    Radiologists rely upon the talents of the technologists with whom they work. Indeed, a good technologist will only enhance the radiologist's performance. Radiological technologists no longer solely take radiographs, but are involved in many more detailed areas of imaging, such as computered tomography, magnetic resonance imaging, nuclear radiology, ultrasound, angiography, and special procedures. They are also required to make decisions that affect the radiological examination. Besides the degree in radiological technology (RT), advanced degrees in nuclear medicine technology (NMT) and diagnostic medical sonography (RDMS) are attainable. The liability of the technologist is not the same as the radiologist involved, but the liability is potentially real and governed by a subdivision of jurisprudence known as agency law. Since plaintiffs and attorneys are constantly searching for new frontiers of medical liability, it is wise for the radiologist and technologist to be aware of the legalities governing their working relationship and to behave accordingly. The legal principles that apply to this working relationship are discussed in this chapter, followed by a presentation of some relevant and interesting cases that have been litigated

    Digital radiography (DR) is one of several new products that have changed our work processes from hard copy to digital formats. The transition from analog screen-film radiography to DR requires thorough user education because of differences in image production, processing, storage and evaluation between the forms of radiography. Without adequate education, radiologic technologists could unknowingly expose children to higher radiation doses than necessary for adequate radiograph quality. To evaluate knowledge about image quality and dose management in pediatric DR among radiologic technologists in the U.S. This communication describes a survey of 493 radiologic technologists who are members of the American Society of Radiologic Technologists (ASRT) and who evaluated the current state of radiological technologist education in image quality and dose management in pediatric DR. The survey included 23 survey questions regarding image acquisition issues, quality assurance, radiation exposure and education in DR of infants and children. Radiologic technologists express many needs in areas of training and education in pediatric DR. Suggested improvements include better tools for immediate feedback about image quality and exposure, more information about appropriate technique settings for pediatric patients, more user-friendly vendor manuals and educational materials, more reliable measures of radiation exposure to patients, and more regular and frequent follow-up by equipment vendors. There is a clear and widespread need for comprehensive and practical education in digital image technology for radiologic technologists, especially those engaged in pediatric radiography. The creation of better educational materials and training programs, and the continuation of educational opportunities will require a broad commitment from equipment manufacturers and vendors, educational institutions, pediatric radiology specialty organizations, and individual imaging specialists.

    A health survey of more than 143,000 radiologic technologists is described. The population was identified from the 1982 computerized files of the American Registry of Radiologic Technologists, which was established in 1926. Inactive members were traced to obtain current addresses or death notifications. More than 6000 technologists were reported to have died. For all registrants who were alive when located, a detailed 16-page questionnaire was sent, covering occupational histories, medical conditions, and other personal and lifestyle characteristics. Nonrespondents were contacted by telephone to complete an abbreviated questionnaire. More than 104,000 responses were obtained. Most technologists were female (76%), white (93%), and employed for an average of 12 years; 37% attended college, and approximately 50% never smoked cigarettes. Radiation exposure information was sought from employer records and commercial dosimetry companies. Technologists employed for the longest times had the highest estimated cumulative exposures, with approximately 9% with exposures greater than 5 cGy. There was a high correlation between cumulative occupational exposure and personal exposure to medical radiographs, related, in part, to the association of both factors with attained age. It is interesting that 10% of all technologists allowed others to practice taking radiographs on them during their training. Nearly 4% of the respondents reported having some type of cancer, mainly of the skin (1517), breast (665), and cervix (726). Prospective surveys will monitor cancer mortality rates through use of the National Death Index and cancer incidence through periodic mailings of questionnaires. This is the only occupational study of radiation employees who are primarily women and should provide new information on the possible risks associated with relatively low levels of exposure

    Full Text Available Background The number of casualties and critically ill patients referred to radiology departments increased during the past decade, which caused the risk of cardiac arrest in radiology departments to increase considerably. Objectives The current study aimed to evaluate the knowledge and attitude of radiology technologists regarding Cardiopulmonary Resuscitation (CPR. Patients and Methods After approval a cross sectional study was designed. Ninety five radiology technologists (male and female were selected in four tertiary referral hospitals in Ahvaz, Iran. Accordingly, 87 radiologic technologists of which agreed to participate in the study. The researchers developed a questionnaire. The questionnaire consisted of three distinct sections including demographic data, attitude, and technical knowledge questions. Reliability of the technical knowledge questions were evaluated using Cronbach’s alpha (76%. Data collection was performed using interview method. Results Of the total 87 questionnaires, one was incomplete. None of the participants had attended a training program since employment. The average scores of attitude towards CPR and technical knowledge were 80 ± 8.9 and 8.8 ± 2.3, respectively. A correlation was observed between age and work experience (r = 0.866, P ≤ 0.0001, age and technical knowledge (r = 0.380, P ≤ 0.0001, work experience and technical knowledge (r = 0.317, P = 0.003, and attitude and technical knowledge (r = 0.397, P ≤ 0.0001. Also a correlation was observed between work experience and attitude (r = 0.385, P ≤ 0.0001. No significant difference was observed between male and female subjects’ technical knowledge (P ≥ 0.05 and attitude (P ≥ 0.05. Conclusions It can be concluded that, although the attitude of participants towards CPR was positive in general, their technical knowledge was poor. This finding should urge decision-makers to consider delivering in-service training courses to radiology technologists

    Japanese radiological technologists occupationally have chances of receiving low doses of ionizing radiation. A cohort study was started on them in 1981, since knowledge of the mortality and health of this population is pertinent to the evaluation of the risk from low-level exposure to radiation. A sampling of 2028 Japanese radiological technologists born before 1933 was followed from 1969 to 1982. All deaths were confirmed by checking copies of family registers and the causes were obtained from death certificates. The deaths observed within this group were compared with the expected number of deaths from major causes as estimated using the Japanese life table of 1975. The number of deaths from all causes, 131, was less than the expected 182.39, a difference that is statistically significant at the 1% level. The observed number of deaths from all malignant neoplasms, 51, was slightly larger than that of the expected 48.94, although the difference was not statistically significant. However, there was a significant excess of observed deaths from brain tumour and malignant neoplasms of male urogenital organs in comparison with expected deaths. Deaths from anaemia also significantly exceeded the expected level. The relationship between dose level and cause of death as adjusted by age at death and first year of employment was investigated using contingency table analysis. Accumulated occupational doses were estimated for 599 of the population of 2028. The relative risk of mortality ratios for all causes of death and cancer of all sites in four dose categories, <50, 50-74, 75-99 and 100+ rad, increased with dose but the statistical tests did not show any significant association. Observation and analysis should be continued to check our present findings further and obtain more complete data. (author)

    Medical radiation workers were among the earliest occupational groups exposed to external ionizing radiation due to their administration of a range of medical diagnostic procedures and accounted for 7.4 million worldwide in 2008. Ionizing radiation is the confirmed human carcinogen for most organ sites. The aims of the study is to evaluate the association between occupational practices including radiation exposure and thyroid cancer risk among radiologic technologists. We found no significant association between the risk of thyroid cancer and the majority of work practices among diagnostic radiation technologists in general. However workers performing fluoroscopy and interventional procedures showed increased risks although the lack of a clear exposure– response gradient makes it difficult to draw clear conclusions. Future studies with larger sample size and detailed work practices implementation are needed to clarify the role of occupational radiation work in thyroid cancer carcinogenesis.

    To investigate stress levels and causes of stress among radiologic technologists and determine whether an intervention could reduce stress in a selected radiologic technologist population. Demographic characteristics and data on preintervention stress sources and levels were collected through Internet-based questionnaires. A 6-week, self-administered, mindfulness-based stress-reduction program was conducted as a pilot intervention with 42 radiologic technologists from the Veterans Administration Medical Center. Data also were collected postintervention. Identified sources of stress were compared with findings from previous studies. Some radiologic technologists experienced improvement in their perceptions of stress after the intervention. Sources of stress for radiologic technologists were similar to those shown in earlier research, including inconsistent management, poor management communication, conflicting demands, long work hours, excessive workloads, lack of work breaks, and time pressures. The mindfulness-based stress-reduction program is an example of an inexpensive method that could improve personal well-being, reduce work errors, improve relationships in the workplace, and increase job satisfaction. More research is needed to determine the best type of intervention for stress reduction in a larger radiologic technologist population.

    The retrospective cohort study of 'Cancer incidence among persons, working at ionizing radiation environment' was performed. The cohort consisted of 2034 persons (13.82% males and 86.18% females). Among them 475 were radiologists (doctors), 868 - radiologic technologists (all of them females) and 470 nurses (cleaners in radiology departments). The members of the cohort were followed -up retrospectively from 01.01.1978 until 31.12.1977. Standard Incidence Ratio for all cancers in the cohort of female radiologic technologists was 1,31 [0,90-1,85], of female nurses -1,99 [1,26-2,99]. The size of cohorts and follow-up period were too small for site - specific analysis of cancer incidence. (author)

    Worldwide increase in the prevalence of abnormal anthropometric indices (i.e., body mass index (BMI), and waist circumference (WC)) are associated with increased risk of death and adverse health outcomes which causes great burden in public health. Studies on the association between radiation exposure and altered anthropometric indices reported both positive and negative associations in atomic bomb and childhood cancer survivors. We have initiated a radiologic technologists health study to investigate occupational radiation exposure and their health effects. Therefore, this study aims to investigate the association between occupational radiation dose with BMI and WC in radiologic technologists in South Korea. These results explain that occupational radiation exposure can possibly alter BMI and WC. Therefore, further study is required to verify the prospective causal effect of radiation exposure on anthropometric indices.

    According to the astonishing progress of medical science, the medical roles of the radiologic technologist are increasing gradually and specializing highly. However, there are the wide disagreements the actual roles of the radiologic technologists at clinics and the relating rules of the medical law. Therefore, it is required that the medical law should be corresponded with the actual state. To solve these problems. This study has proceeded to make the survey of the present medical law and has tried to offer the most suitable theories to the actual state. This study includes the survey of relevant professional literatures. The major contents of this study are as follows. First, medical technician is written (in Chinese character) at the present medical technician law, and that word is written wrong. So, it should be replaced with Therefore, radiologic technologist should be written Second, the relations between the doctor and the radiologic technologist should be written the 'request or other words' instead of 'direction' Third, in spite of the rules of the present medical law, the medical act of radiologic technologist at clinics should be belonging to the boundary of medical practice. Forth, to present the appropriate medical service to the patients, legal status of radiologic technologist as a member of medical team should be established. Fifth, it is desired that Magnetic Resonance Imaging Technology as a business of radiologic technologist should be provided for in the medical law

    Job satisfaction is very important for adequate manpower management in the medical field. To study job satisfaction among the radiologic technologists, 344 cases were reviewed in five university hospitals and one general hospital. Self-administered questionnaire was used to study their socioeconomic characteristics, working conditions, job satisfaction, and the factors affecting there job satisfaction. The results were as follows : 1. There was statistically significant difference in job satisfaction according to the their department of employment, position, and hospital characteristics. 2. The group that was satisfied with their salary had a higher job satisfaction score, whereas others who were not satisfied ranked lower. 3. The positive answering group on the ability and job recognition ranked higher score on the job satisfaction than the negative answering group. 4. The group that was in good relationship with their superiors and co-workers scored higher on job satisfaction. From the above results, the job satisfaction was high for the group with positive thinking and reply, but the intentin to change their job was low. Considering the fact that these results represent only 6 hospitals from limited arease, therefore, necessary to include more medical facilities nationwide, especially small-medium sized clinics or hospitals where the difficulty with high turnover rate of employment is expected, to study further various factors involving job satisfaction in the future

    In this study a group of experts and clinical radiological technologists were surveyed to evaluate the clinical importance of current subjects in the radiological sciences. For the data collection and analysis, an open-ended questionnaire was distributed to the group of experts, and a multiple choice questionnaire was distributed to radiological technologists. Subjects were classified into 9 groups for analysis of the importance of subjects, and in regard to the questionnaire design for measurement of variables, departments and type of hospital were set up as independent variables, and the 9 groups of subjects were set up as dependent variables. As a result, clinical radiological technologists perceived Diagnostic Imaging Technology and practical courses, including general radiography, CT and MRI, as the most clinically necessary subjects, and the group of experts placed most weight on basic courses for the major. The result of this study suggests that the curriculum should be revised in a way that combines theory and practice in order to foster radiological technologists capable of adapting to the rapidly changing healthcare environment.

    Health survey for 1014 radiological technologists was undertaken in 10 districts in Japan. Estimated radiation doses were based on work duration, the status of radiation protection, X-ray equipments to be used, and exposure conditions. Two hundred and eighty-three technologists aged between 45 and 59 were enrolled in this study. Exposure doses ranged from 2 cGy to 337 cGy. According to exposure doses of either 40 cGy, smoking habits, and drinking habits, the subjects were classified into 7 groups. Clinical laboratory data, in addition to systolic and diastolic blood pressures, were analyzed. In comparing the sole effect of irradiation with that of smoking or drinking, the degree of irradiation effect was less than the other two factors. Smoking had a higher synergistic action than irradiation and drinking. (N.K.)

    Radiologic technologists are one of the occupational groups exposed to the highest dose of radiation worldwide. In Korea, radiologic technologists occupy the largest group (about 33%) among medical radiation workers and they are exposed to the highest dose of occupational dose of radiation as well (1). Although work experience with diagnostic radiation procedure of U.S. radiologic technologists was reported roughly (2), few studies have been conducted for description of overall work practices and the change by calendar year and evaluation of related factors on occupational radiation dose. The aims of the study are to describe work practices and to assess risk factors for occupational radiation dose among radiologic technologists in Korea. This study showed the work practices and occupational radiation dose among representative sample of radiologic technologists in Korea. The annual effective dose among radiologic technologists in Korea remains higher compared with those of worldwide average and varied according to demographic factors, year began working, and duration of working

    This study explored several agenda related to license system, education, professional work of radiological technologists (RTs) and a transition process of law for them to investigate a developmental strategy of RTs as a professional career. The results are as followings: 1. The national license system for RTs was started from 1965, 1965-1972 x-ray technicians (medical assistance), 1973-present (2006) radiotechnologist (medical technologist) since then. 2. The average pass ratio of national license examination (1965-2006) for RTs was 46.6%. The method, subjects and level of the examination should be improved. 3. The education term for RTs has been changed since 1963; 1963-1990 two year college. 1991-1999 three year college, 2000-2006 four year and three year college depending on universities and colleges. As of 2006, there are twelve 4-year universities and eighteen 3-year colleges. The total number of new students were 1,965. 4. The new developmental paradigm should be made for technology education of RTs corresponding to the development of medicine and science. 5. The qualification system of clinical specialists in radio-technology field needs to be operated not by the non-governmental body (The-Korean Radiological Technologists Association) but by the governmental body. 6. The vertical relationship among RTs, doctors and other medical workers should be rebuilt through the revision of law. Especially, doctors and dentists 'guidance authority' for RTs should be changed to 'request authority'. 7. The service extent of RTs should be extended in medical fields corresponding to professional work of RTs and a revision of the law needed for this situation

    We are developing a mammographic ontology to share knowledge of the mammographic domain for radiologic technologists, with the aim of improving mammographic techniques. As a first step in constructing the ontology, we used mammography reference books to establish mammographic terminology for identifying currently available knowledge. This study proceeded in three steps: (1) determination of the domain and scope of the terminology, (2) lexical extraction, and (3) construction of hierarchical structures. We extracted terms mainly from three reference books and constructed the hierarchical structures manually. We compared features of the terms extracted from the three reference books. We constructed a terminology consisting of 440 subclasses grouped into 19 top-level classes: anatomic entity, image quality factor, findings, material, risk, breast, histological classification of breast tumors, role, foreign body, mammographic technique, physics, purpose of mammography examination, explanation of mammography examination, image development, abbreviation, quality control, equipment, interpretation, and evaluation of clinical imaging. The number of terms that occurred in the subclasses varied depending on which reference book was used. We developed a terminology of mammographic techniques for radiologic technologists consisting of 440 terms.

    People who live in Taiwan are getting more and more afraid of radiation. Sometimes the phobia results from distorted knowledge. Radiology technologists, in one hand, are more well-educated in radiation and, in the other hand, have more chance to expose to radiation when they are operating radiation producing medical instruments in their daily life. So we are interested in whether they have enough knowledge to protect themselves. We pick up the radiology technology board examination to make the questionnaire for this study. The population is the radiology technologists who work at department of diagnostic radiology, of radiation therapy and nuclear medicine in medical centers. Statistics is then used to see the relationship between knowledge and the factors including gender, age and career period. Based on statistics, we find out that there is significant correlation between the knowledge with age or education level. Elder or lower education level ones has worse knowledge. Continued education may be highly recommended for radiology technologists to avoid occupational radiation injury. (author)

    The aim of this study was to grasp the actual conditions of the radioprotective education in the educational facilities for radiological technologists, and to discuss the ideal way of radioprotective education toward the 21st century. For this purpose, we sent out the questionnaire concerning the circumstances of radioprotective education to 38 educational facilities for radiological technologists in Japan, including 6 universities, 15 junior colleges and 15 technical schools. This research was carried out on March, 1997, and the answers were obtained total 34 educational facilities (86.8%) (6 universities, 15 junior colleges and 13 technical schools) in total. Among the educational facilities in Japan, universities were much richer than the other two facilities in every respect on the educational circumstances including number and the quality of teaching staffs, educational institutions and equipment, practical training facilities and equipment, the number of collection of books in the library, etc. In the process of education for radiological technologists, the background to cause problems concerning the radioprotective education was largely dependent on the difference of educational schemes in Japan. From the view point of the elevation of educational standard for radiological technologists, it is better to transfer all educational processes to the universities, and give high and full level of radioprotective education in universities. And in the field of the medical radiology, the radioprotection and the management system should also be strengthened. For this purpose, it is also required to revise the related laws drastically, to strengthen lessons related to the radioprotection and to plan the richness in contents of the radioprotective education.

    With the exponential increase in minimally invasive fluoroscopically guided interventional radiologic procedures, concern has increased about the health effects on staff and patients of radiation exposure from these procedures. There has been no systematic epidemiologic investigation to quantify serious disease risks or mortality. To quantify all-cause, circulatory system disease and cancer mortality risks in U.S. radiologic technologists who work with interventional radiographic procedures, we evaluated mortality risks in a nationwide cohort of 88,766 U.S. radiologic technologists (77% female) who completed a self-administered questionnaire during 1994-1998 and were followed through 31 December 2003. We obtained information on work experience, types of procedures (including fluoroscopically guided interventional procedures), and protective measures plus medical, family cancer history, lifestyle, and reproductive information. Cox proportional hazards regression models were used to compute relative risks (RRs) with 95% confidence intervals (CIs). Between completion of the questionnaire and the end of follow-up, there were 3,581 deaths, including 1,209 from malignancies and 979 from circulatory system diseases. Compared to radiologic technologists who never or rarely performed or assisted with fluoroscopically guided interventional procedures, all-cause mortality risks were not increased among those working on such procedures daily. Similarly, there was no increased risk of mortality resulting from all circulatory system diseases combined, all cancers combined, or female breast cancer among technologists who daily performed or assisted with fluoroscopically guided interventional procedures. Based on small numbers of deaths (n=151), there were non-significant excesses (40%-70%) in mortality from cerebrovascular disease among technologists ever working with these procedures. The absence of significantly elevated mortality risks in radiologic technologists reporting the

    Recently, the importance of medical information for radiologic technologists has increased. The purpose of this questionnaire survey was to clarify the method of acquiring skill in medical information for radiologic technologists from the point of view of the managers of radiology departments. The questionnaire was sent to 260 hospitals that had introduced picture archiving and communication systems (PACSs) for the person responsible for medical information in the radiology department. The response rate was 35.4% (92 hospitals). The results of this survey clarified that few hospital have staff for medical information in the radiology department. Nevertheless, the excellent staff who have the skills to troubleshoot and develop systems are earnestly needed in radiology departments. To solve this problem, many technologists should understand the content, work load, and necessity of medical information. In addition, cooperation between radiologic technologist schools and hospitals is important in the field of medical information education. (author)

    Radiologic technologists currently consist of 31.5% among diagnostic radiation workers in South Korea. Among diagnostic radiation workers, radiologic technologists receive the highest annual and collective doses in South Korea. Comprehensive assessment of the work practices and associated radiation doses from diagnostic radiology procedures should be undertaken for effective prevention for radiologic technologists. Using the national survey, this study aimed (1) to explore the distribution of the work procedures performed by gender, (2) to evaluate occupational radiation exposure by work characteristics and safety compliance, (3) to identify the primary factors influencing high radiation exposure among radiologic technologists in South Korea. This study provided detailed information on work practices, number of procedures performed on weekly basis, and occupational radiation doses among radiologic technologists in South Korea. Average radiation dose for radiologic technologists is higher than other countries, and type of facility, work safety, and wearing lead apron explained quite a portion of increased risk in the association between radiology procedures and radiation exposure among radiologic technologists.

    The most important sources of ionizing radiation for general public are medical sources. Good working protocols and radiological protections measurements provided significant reduction of patients and professional doses. Medical users of ionizing radiation are radiological technologists. The purpose of this paper is to point out to several facts and errors in radiation protection educational programs for radiological technologists. Medical College educational program covers main specific topics in radiation protection, but there are some omissions in training process. Radiological technologists must be actively involved in radiation protection. Following ethical standards they will reach higher standards than the law requires

    Recently the suits for medical malpractice are gradually increasing in this country. The main purpose of this study is to excavate the most suitable theories about civil liabilities on medical malpractice by radiological technologist. To solve the above-mentioned problems in medical malpractice, I have proceeded to make a survey of traditional theories and tried to excavate the most suitable theories for our medical circumstances among those theories. Both domestic and foreign relevant professional literatures and legal cases were investigated in this study. Several important findings of this study are as follows. First, the nature of legal interrelationship between radiological technologist and physician(or the representative of a hospital) is to define the content of employment. But in the eye of medical law, the interrelationship between radiological technologist and physician is written that radiological technologist should be directed by physician. Second, the nature of legal interrelationship between patient and physician(or the representative of a hospital) is to define the content of legal obligation of physician(or the representative of a hospital), and radiological technologist execute his obligation as proxy for physician. Therefore, patient can not clame any legal right to radiological technologist. Third, radiological technologist has the obligation of Due Care in medical practice. Fourth, on the medical malpractice by radiological technologist the civil liability can be treated as either tortious liability or contractual liability, and physician (or the representative of hospital) take the responsibility for the damage compensation. In this case, physician has the right of indemnity to radiological technologist. But it should be dinied or extremely limited

    This paper analyzes differences and changes within and between the occupation of nurses, radiological technologists, and medical technologists concerning starting salary from April 2005 to March 2009. This paper also investigates the percentage of difference in the amount of starting salary of nurses, radiological technologists, and medical technologists according to their educational attainments. The research-target used was the full-time-job-opening data provided to Okayama University within the given period of time, which specifies the amount of starting salary. The result shows that one's educational background has a crucial influence on the amount of one's starting salary. In fact, the percentage of the amount of starting salary base on one's educational attainment all increased in nurses, radiological technologists, and medical technologists from April 2007 to March 2009. However, this percentage for radiological technologists remains only 50% of increase, which was less significant than other two professional occupations. Moreover, the result indicates a crucial change in the amount of basic starting salary: while the amount of basic starting salary of nurses in 2008 has increased since 2005, that of radiological technologists has dropped remarkably. If this situation is not improved in the near future, the health-service sector may experience a decrease in the number of skilled practitioners which, in turn, will result in a decline in quality of medical care.

    To evaluate risks of hematopoietic and lymphoproliferative malignancies among medical workers exposed to protracted low-to-moderate-dose radiation exposures, a follow-up investigation was conducted in a nation wide cohort of U. S. radiologic technologists. eligible for this study were 71.894 technologists (78% female) certified for at least 2 years during 1926-82, who had responded to a baseline mail questionnaire during 1983-89, were cancer-free except for non-melanoma skin cancer at completion of the questionnaire, and completed a second questionnaire during 1994-98 or died through August 1998. There were 241 technologists with hematopoietic or lymphoproliferative malignancies, including 41 with leukemia subtypes associated with radiation exposures (specifically acute myeloid, acute lymphoid and chronic myeloid leukemias, hereafter designated radiogenic leukemias), 23 with chronic lymphocytic leukemia, 28 with multiple myeloma, 118 with non-Hodgkin lymphoma, and 31 with Hodgkin lymphoma. Of the 241 hematopoietic or lymphoproliferative malignancies identified among radiologic technologists, 85 percent were confirmed by medical records or death certificates, including 98 percent of radiogenic leukemia. Risks of the hematopoietic or lymphoproliferative malignancies were evaluated in relation to questionnaire-derived information on employment as a radiologic technologist, including procedures, work practices, and protective measures. cox proportional hazards regression analysis was used to compute relative risks and 95% confidence intervals, using age at diagnosis as the response, stratifying at baseline for birth cohort in 5-year intervals, and adjusting for potential confounding. Risks were not increased for any of the hematopoietic or lymphoproliferative neoplasms according to year first worked or total duration of years worked as radiologic technologist. For the combined radiogenic leukemias, risks rose significantly with an increasing number of years worked

    The study examined the changes in the decreased facial exposure dose for radiological technologists depending on increased distance between the workers and the X-ray tube head during intraoral radiography. First, the facial phantom similar to the human tissues was manufactured. The shooting examination was configured to the maxillary molars for adults (60 kVp, 10 mA, 50 msec) and for children (60 kVp, 10 mA, 20 msec), and the chamber was fixed where the facial part of the radiation worker would be placed using the intraoral radiography equipment. The distances between the X-ray tube head and the phantom were set to 10 cm, 15 cm, 20 cm, 25 cm, 30 cm, 35 cm, and 40 cm. The phantom was radiated 20 times with each examination condition and the average scattered doses were examined. The rate at the distance of 40 cm decreased by about 92.6% to 7.43% based on the scattered rays radiated at the distance of 10 cm under the adult conditions. The rate at the distance of 40 cm decreased by about 97.6% to 2.58% based on the scattered rays radiated at the distance of 10 cm under the children conditions. Protection from the radiation exposure was required during the dental radiographic examination.

    It is essential to predict the long-term supply and demand for the number of radiologic technologists as medical resources. However, it is difficult to predict the number of Japanese radiologic technologists due to complex and intertwining factors. Our purpose in this study was to predict the future number of radiologic technologists using the concept of system dynamics (SD), and to clarify the effects of relevant factors. In order to estimate the number of Japanese radiologic technologists, we constructed a flow diagram using the concept of SD. We simulated the number of radiologic technologists for the following 4 cases: maintaining the status quo, a change in the pass rate for the national examination, a change in the post-graduate employment rate, and a change in the rate of continuing education. The result for the predicted number of radiologic technologists was 50,509 in 20 years, which is 4,394 (9.5%) more than the present number, and 50,166 in 40 years, which is 4,051 (8.8%) more than the present number. For the factors influencing the number of technologists, the influence of the pass rate on the national examination and that of the rate for post-graduate employment was larger than that of the rate of continuing education in graduate school. The number of Japanese radiologic technologists will increase until 2033 and decrease until 2042, and it does not change after 2042 in case of maintaining the status quo. Implementing the concept of SD allowed us easily to clarify the factors influencing the predicted number of radiologic technologists.

    Distribution of microorganisms were examined for the bucky tables in the radiology rooms of the department of radiological technology, the aprons, handles of various apparatus, handles of mobile radiological apparatus, and hands of the radiological technologists. As a result, relatively larger amounts of bacteria were found on the handles of the mobile radiological apparatus and the aprons. Among the isolated bacteria, Acinetobacter baumanni (7.3%), Klebsiella pneumoniae (6.7%), Staphylococcus aureus (3.9%), Serratia liquefaciens (1.7%), Enterobacter cloaceae (0.6%), Providenica rettgeri (0.6%) are known as the cause of nosocomial infection (hospital acquired infection). In addition, similar colonies were also found on the hands of the radiological technologists such as microorganisms of Klebsiella pneumoniae (8.4%), Staphylococcus aureus (6.6%), Yersinia enterocolotica (5.4%), Acinetobacter baumanni (4.2%), Enterobacter cloaceae (2.4%), Serratia liquefaciens (1.8%), Yersinia pseuotuberculosis (18%), Enterobacter sakazakii (1.2%), and Escherichia coli (0.6%). In particular, this result indicates clinical significance since Staphylococcus aureus and Escherichia coli show strong pathogenicity. Therefore, a continuous education is essential for the radiological technologists to prevent the nosocomial infection.

    We made a detailed study on the course of study in radiation safety control prescribed on March 28, 2003. Questionnaires were sent to 39 training schools for radiological technology, to which 66.7% replied (26/39). Subjects on radiation safety control must include knowledge and technology in both radiation control and medical safety. The contents for instruction of radiation control were in accordance with those given in the traditional program; however, some discrepancies were found in the contents of medical safety. As medical safety, emphasized by the revised Medical Service Law, is regarded as very important by many hospitals, safety control education that include medical ethics should be required as part of the curriculum in the training schools for radiological technologists.

    Ionizing radiations are used in areas such as health, industry and safety, not only in the private sector, but also in the public. Thus, it is necessary the radiological protection, a set of studies and practices that increases the safety in these applications, where the professional involved is the technologist in radiology. The objective was to analyze the contents effectively required by the Brazilian public agencies in their competitions for radiology technologist, regarding the area of radiological protection, identifying their profile of requirement. It consisted of three stages: first, a survey of all the public competitions already carried out in the country up to the end of 2016, that requested a diploma of graduation in Technology in Radiology; second, all the specific questions were collected and grouped in an electronic text file; third, issues involving radiological protection were segregated, using as reference the 2017 edition of the National Nuclear Energy Commission's General Proof of Radioprotection Supervision. The results showed that almost 40% of the competition questions were about radiation protection. From this sampling, the topics most covered were: radiological safety (36%), fundamentals of atomic and nuclear physics (24%) and biological effects of radiation (16%). It is concluded that the competitions for radiologist technologist have the profile of concentration of exigency in radiological safety, fundamentals of atomic and nuclear physics and biological effects of the radiations

    The development of digital radiography (DR) has provided numerous benefits for pediatric imaging, including the ability to post-process images and to make images immediately available for access by care providers. However, DR presents several significant challenges for the radiologic technologists who are responsible for operating the equipment and producing high-quality images in children. This paper discusses those challenges, including lack of standardization among vendors, particularly with regard to the exposure indicator; lack of pediatric-specific educational materials and pediatric techniques; the need for manual technique instead of the use of automatic exposure control in smaller children; and complications related to field size, collimation and shielding in small children. Specific actions and design modifications that might facilitate the effective management of these challenges will be also described. The implementation of measures to promote the production of optimal images while minimizing radiation exposure requires cooperation and communication among imaging professionals, manufacturers and regulatory agencies.

    Technologists working in nuclear medicine (NM) are exposed to higher radiation doses than most other occupationally exposed populations. The aim of this study was to estimate the risk of cancer in NM technologists in relation to work history, procedures performed and radioprotection practices. From the US Radiologic Technologists cohort study, 72 755 radiologic technologists who completed a 2003-2005 questionnaire were followed for cancer mortality through 31 December 2012 and for cancer incidence through completion of a questionnaire in 2012-2013. Multivariable-adjusted models were used to estimate HRs for total cancer incidence and mortality by history of ever performing NM procedures and frequency of performing specific diagnostic or therapeutic NM procedures and associated radiation protection measures by decade. During follow-up (mean=7.5 years), 960 incident cancers and 425 cancer deaths were reported among the 22 360 technologists who worked with NM procedures. We observed no increased risk of cancer incidence (HR 0.96, 95% CI 0.89 to 1.04) or death (HR 1.05, 95% CI 0.93 to 1.19) among workers who ever performed NM procedures. HRs for cancer incidence but not mortality were higher for technologists who began performing therapeutic procedures in 1960 and later compared with the 1950s. Frequency of performing diagnostic or therapeutic NM procedures and use of radioprotection measures were not consistently associated with cancer risk. No clear associations were observed for specific cancers, but results were based on small numbers. Cancer incidence and mortality were not associated with NM work history practices, including greater frequency of procedures performed. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

    This study attempts to provide basic information on overseas employment to the radiological technologists and students majoring in radiology in Korea who consider the overseas employment by investigating the job consciousness for radiological technologists in Canada and Australia which have a high level of interest for overseas employment and want to compare their status with that of Korean radiological technologists. This study was performed by visiting hospitals such as Prince George Regional Hospital, 1475 Edmonton Street, Prince George, BC, Canada on August 13, 2007, Alfred Hospital, Commercial Road Melbourne 3004, Australia on August 4, 2008, and other Korea hospitals that show the similar scale as Canada and Australia on September 10, 2007. The results were summarized as follows : 1. Differences were observed in this sexual composition, such as 18 males (90%) in Korea, 14 females (73.7%) in Canada, and 25 females in Australia (86.2%). 2. The item of 'aptitude' which is one of the most important criteria, showed the highest level in Korea, Canada, and Australia, and the second most considered item was 'salary'. 3. In the values in jobs, the items of 'economic self-sufficiency', 'recognized by others', and 'establishing a social position' represented high levels in Korea, and the items of 'like the job itself', 'establishing self-actualization', 'feel the meaning of life', and 'make new friends' showed high levels in Canada and Australia. 4. Regarding the item of 'a job is important as much as a marriage', 'Yes' showed high level in Korea, and 'No' showed high levels in Canada and Australia. 5. Radiological technologists in Korea demonstrated a low level in the job consciousness compared to those of Canada and Australia. Although this study shows some limitations for showing whole idea of radiological technologists due to the lack of the scope in samples for each country as a practical manner, this study can be regarded significant to compare some countries

    The objective of this study was to investigate representative occupational characteristics and radiation exposure for South Korean radiologic technologists. The authors conducted a national survey by stratified sampling of South Korean administrative districts and types of medical facilities. A total of 585 technologists were surveyed, and survey data were linked with dosimetry data from the National Dose Registry. A total of 73 % of radiologic technologists sampled were male, 62 % were younger than age 40 and 86.5 % began employment after 1990. The most frequent practices among radiologic technologists were diagnostic routine X-ray followed by computed tomography (CT) and portable X-ray. Male workers were more frequently involved in CT, portable X-ray and interventional radiology whereas female workers carried out most mammography procedures. The average annual effective dose was 2.3 mSv for male and 1.3 mSv for female workers. The dose was significantly higher for workers in the provinces and those who had recently started work.

    The applications of radiation to the medical field are increasing steadily, along with advances in radiation technology and development of new medical equipment. Medical applications of radiation differ from applications in other fields, because the patient is exposed to radiation during examination and radiotherapy. Consequently, it is important that training courses in radiation safety for radiological technologists, medical doctors and nurses be periodically carried out to ensure a more effective and safe utilization of radiation. Furthermore, it is important that such training be based on a practical education curriculum, including basic knowledge, technical training, and safe habits. In this paper, we discuss the appropriate role and attitudes of the radiological technologist in radiation safety education. (author)

    To describe the study design, methods, and baseline results of a prospective cohort of radiologic technologists which we have initiated in South Korea. The cohort participants were enrolled through a self-administered questionnaire survey administered from April 2012 to May 2013. Survey data were linked with radiation dosimetry, a cancer registry, and health insurance data by personal identification numbers. A nationwide representative survey was also conducted using a stratified random sampling design with face-to-face interviews. A total of 12,387 radiologic technologists were enrolled, which accounted for approximately 63 % of all diagnostic radiologic technologists working in South Korea. For nationwide survey, 585 workers were interviewed using the detailed questionnaire, and buccal cells were also collected by scraping the inside of the cheek. The majority of study subjects were under 50-year-old and male workers. The average annual effective dose of radiation declined both men (from 2.75 to 1.43 mSv) and women (from 1.34 to 0.95 mSv) over the period of 1996-2011. A total of 99 cancers (66 cancers in men and 33 in women) were reported from 1992 to 2010. The standardized incidence ratio of all cancer combined was significantly lower in men (SIR = 0.75, 95 % CI 0.58-0.96) than general population, but the ratios for thyroid cancer were significantly higher than expected among both men and women. This cohort provides comprehensive information on work activities and health status of diagnostic radiologic technologists. In addition, the nationwide representative sample provides unique opportunities compared with previous radiologic technologist studies.

    The literature has suggested that advancement within politics, academia and the health professions is influenced by gender. Purpose The authors conducted a survey to determine whether advancement was equal by gender in the radiologic science disciplines of nuclear medicine technology, radiation therapy and radiography. The survey was mailed to 900 subjects, 300 from each discipline. The discipline groups were further stratified by initial year of American Registry of Radiologic Technology certification; the authors selected 100 subjects from each discipline who initially were certified in 1978, 100 in 1988 and 100 in 1998. Approximately 33% of those selected responded. The findings of the study provided no evidence that men are promoted differentially than women. Women perceived that men were paid more for the same work. It appears that gender bias is pervasive outside of promotion decisions and, indeed, that some illegal actions (eg, sexual harassment, inappropriate gender-related interview questions) take place in radiologic science clinical settings. It is hoped that this study will set a baseline for future research on whether there is a glass ceiling effect in radiologic clinical practice and stimulate discussion of the importance of equal opportunity regardless of gender.

    The proliferation of pediatric urgent care centers has increased the need for diagnostic imaging support, but the impact of employing radiology technologists at these centers is not known. The purpose of this study was to evaluate radiographic impact and quality at urgent care centers with and without radiology technologists. A retrospective case-control study was conducted comparing 235 radiographic examinations (study) performed without and 83 examinations (control) performed with a radiology technologist at the authors' pediatric urgent care centers. Studies were evaluated for quality using a five-point, Likert-type scale (1 = poor, 5 = best) regarding field of view, presentation, and orthogonal view orientation. Studies were also evaluated for the incidence of positive results, need for repeat imaging, and discrepancies between initial study and follow-up. Imaging quality comparisons between study and control groups were statistically different for field of view (3.98 versus 4.29, P = .014), presentation (4.39 versus 4.51, P = .045), and orthogonal view orientation (4.45 versus 4.69, P = .033). The incidence of repeat imaging was similar (4.7% versus 2.4%, P = 0.526), as well as the discrepancy rates (3.4 versus 2.4%, P = 1.00). The incidence of abnormal radiographic findings for the study and control groups was similar (40.9% versus 34.9%, P = .363). Radiography is an important triage tool at pediatric urgent care centers. It is imperative to have optimal radiographic imaging for accurate diagnosis, and imaging quality is improved when radiology technologists are available. If not feasible or cost prohibitive, it is important that physicians be given training opportunities to bridge the quality gap when using radiographic equipment and exposing children to radiation.

    Radiological Technologists deals with the life of a person which means professional competency is essential for the job. Nevertheless, there have been no studies in Korea that identified the job competence of radiologists. In order to define the core job competencies of Korean radiologists and to present the factor models, 147 questionnaires on job competency of radiology were analyzed using 'PASW Statistics Version 18.0' and 'AMOS Version 18.0'. The valid model consisted of five core job competencies ('Patient management', 'Health and safety', 'Operation of equipment', 'Procedures and management') and 17 sub – competencies. As a result of the factor analysis, the RMSEA value was 0.1 and the CFI, and TLI values were close to 0.9 in the measurement model of the five core job competencies. The validity analysis showed that the mean variance extraction was 0.5 or more and the conceptual reliability value was 0.7 or more , And there was a high correlation between subordinate competencies included in each subordinate competencies. The results of this study are expected to provide specific information necessary for the training and management of human resources centered on competence by clearly showing the job competence required for radiologists in Korea's health environment

    For radiological technologists, it is very important to understand the principle of computed tomography (CT) and CT artifacts derived from mechanical and electrical failure. In this study, a CT system for educating radiological technologists was developed. The system consisted of a cone-beam CT scanner and educational software. The cone-beam CT scanner has a simple structure, using a micro-focus X-ray tube and an indirect-conversion flat panel detector. For the educational software, we developed various educational functions of image reconstruction and reconstruction parameters as well as CT artifacts. In the experiments, the capabilities of the system were evaluated using an acrylic phantom. We verified that the system produced the expected results. (author)

    Self-completed questionnaires were used to obtain information on exposures and otherb factors necessary to evaluated disease risks. Although reliability of lifetime sun exposure of U.S. radiologic technologists and life-style factors, medical exams, and disease history of Korean nuclear power plants workers (2) were reported, few studies have evaluated the reliability of information obtained on radiation-related work in epidemiologic investigations. The aims of the study is to assess reliability of self-reported questionnaire for occupational radiation work in the radiologic technologists in Korea. Overall agreement and kappa regarding radiation work procedure, work practice, and work history were similar to those generally found for factors typically used in epidemiologic studies such as smoking (98% and 0.95) and alcohol consumption (88% and 0.67), and higher than physical activity (76% and 0.51).

    A computer program was created to train technologists to perform chest X-rays in crying infants at maximum inspiration. Videos of 4 children were used. Using a computer program, the moment of deepest inspiration was determined in the video in the single frame view. During the normal running video, 14 technologists (3 with significant experience, 3 with little experience and 8 with very little experience in pediatric radiography) simulated a chest radiograph by pushing a button. The computer program stopped the video and the period of time to the optimal moment for a chest x-ray was calculated. Every technologist simulated 10 chest X-rays in each of the 4 video clips. The technologists then trained themselves to perform chest X-rays at optimal inspiration like playing a computer game. After training, the test was repeated. Changes were evaluated by t-test for unpaired samples (level of significance p < 0.05). Although the differences improved in all children, minimal deviation from the optimal moment for taking an X-ray at inspiration occurred in the periodically crying child (0.21 sec before and 0.13 sec after training). In a non-periodically crying infant, the largest differences were shown. The values improved significantly from 0.29 sec to 0.22 sec. The group with substantial experience in pediatric radiology improved significantly from 0.22 sec to 0.15 sec. The group with very little experience in pediatric radiology showed worse results (improvement from 0.29 sec to 0.21 sec). (orig.)

    The purpose of this study was to analyze factors that could affect health of radiological technologists, which is useful for health care and development of programs for health promotion. Subjects were 234 of radiological technologists who work in general hospitals. Some questionnaires were made about perceptions of health condition and promotional behavior of health for this study. The questionnaires of health perception were 20 items that consist of the present condition of health, health concern and sensitivity. The reliability was sufficient(Cronbach's α=0.79). The other questionnaires about health promotion behavior were 47 items that consist of self-realization, health responsibility, exercise, nutrition, personal relationships, and stress management. The results turned out to be was sufficient (Cronbach's α=0.93). Every data was treated statistically, comparison of average(t-test, ANOVA), correlation, and multiple regression. Related factors to health promotion behavior were age, marriage, salary, class of one's position, career, employment, and religion, in general features. In health life habit, related factors were smoke and exercise. Results of health promotion behavior was 2.90 of mean score, 0.37 of standard deviation. Correlations between factors of health perception and health promotion behavior was positive(p<0.01). Health promotion behavior were affected by sensitivity, presents condition of health, exercise, smoke, career. Sensitivity was the most affectable variable, which means that promotional behavior score became higher and higher as the score of sensitivity and present condition were increased. In addition, persons who exercise regularly, had been smoked, and has higher career showed higher score of promotional behavior. Radiological technologists have to keep their health, trying not to infected by a disease. Most of all, no smoking and regular exercise are the most important thing to all of members.

    There have been few studies of work history and mortality risks in medical radiation workers. We expanded by 11 years and more outcomes our previous study of mortality risks and work history, a proxy for radiation exposure. Using Cox proportional hazards models, we estimated mortality risks according to questionnaire work history responses from 1983 to 1989 through 2008 by 90,268 US radiological technologists. We controlled for potential confounding by age, birth year, smoking history, body mass index, race and gender. There were 9566 deaths (3329 cancer and 3020 circulatory system diseases). Mortality risks increased significantly with earlier year began working for female breast (p trend=0.01) and stomach cancers (p trend=0.01), ischaemic heart (p trend=0.03) and cerebrovascular diseases (p trend=0.02). The significant trend with earlier year first worked was strongly apparent for breast cancer during baseline through 1997, but not 1998-2008. Risks were similar in the two periods for circulatory diseases. Radiological technologists working ≥5 years before 1950 had elevated mortality from breast cancer (HR=2.05, 95% CI 1.27 to 3.32), leukaemia (HR=2.57, 95% CI 0.96 to 6.68), ischaemic heart disease (HR=1.13, 95% CI 0.96 to 1.33) and cerebrovascular disease (HR=1.28, 95% CI 0.97 to 1.69). No other work history factors were consistently associated with mortality risks from specific cancers or circulatory diseases, or other conditions. Radiological technologists who began working in early periods and for more years before 1950 had increased mortality from a few cancers and some circulatory system diseases, likely reflecting higher occupational radiation exposures in the earlier years.

    The purpose of this study was to analyze factors that could affect health of radiological technologists, which is useful for health care and development of programs for health promotion. Subjects were 234 of radiological technologists who work in general hospitals. Some questionnaires were made about perceptions of health condition and promotional behavior of health for this study. The questionnaires of health perception were 20 items that consist of the present condition of health, health concern and sensitivity. The reliability was sufficient(Cronbach's {alpha}=0.79). The other questionnaires about health promotion behavior were 47 items that consist of self-realization, health responsibility, exercise, nutrition, personal relationships, and stress management. The results turned out to be was sufficient (Cronbach's {alpha}=0.93). Every data was treated statistically, comparison of average(t-test, ANOVA), correlation, and multiple regression. Related factors to health promotion behavior were age, marriage, salary, class of one's position, career, employment, and religion, in general features. In health life habit, related factors were smoke and exercise. Results of health promotion behavior was 2.90 of mean score, 0.37 of standard deviation. Correlations between factors of health perception and health promotion behavior was positive(p<0.01). Health promotion behavior were affected by sensitivity, presents condition of health, exercise, smoke, career. Sensitivity was the most affectable variable, which means that promotional behavior score became higher and higher as the score of sensitivity and present condition were increased. In addition, persons who exercise regularly, had been smoked, and has higher career showed higher score of promotional behavior. Radiological technologists have to keep their health, trying not to infected by a disease. Most of all, no smoking and regular exercise are the most important thing to all of members.

    Ionizing and ultraviolet (UV) radiations are known to increase the risk of non-melanoma skin cancer. However, the effect of chronic or protracted exposure to ionizing radiation and the modifying effect of UV exposure on skin cancer risk are not well defined. We evaluated risk of basal cell carcinoma (BCC) and squamous cell carcinoma (SCC) of the skin among radiologic technologists in the United States. A total of 1,355 incident cases with BCC and 270 with SCC were ascertained in 65,304 white technologists between the baseline questionnaire survey in 1983-1989 and the follow-up survey in 1994-1998. Analysis by Cox's proportional hazard model, stratified by birth cohort and adjusted for potential confounders including pigmentation characteristics (skin complexion, eye and hair color) and estimated index of residential UV exposure, indicated significantly increased relative risks for BCC, but not for SCC, among early technologists who likely had high radiation exposure. Relative risks of BCC were 1.42 (95% CI: 1.12-1.79), 2.04 (95% CI: 1.44-2.88), and 2.17 (95% CI: 1.14-4.10) among those who first worked in the 1950s, 1940s, and before 1940, respectively (p for trend: <0.01), compared with technologists who first worked after 1960. The effects of ionizing radiation on BCC were not significantly modified by UV exposure (p for effect modification: 0.31), but they were modified by eye and hair color (p=0.01 and 0.03), with light eye or hair color conferring a higher radiation-related risk. In contrast, relative risks of both BCC and SCC significantly increased with increasing residential UV exposure index, and no modifying effects of pigmentation characteristics were observed. This study provides evidence of increased BCC risk associated with chronic, occupational exposure to a low-to-moderate level of ionizing radiation, which may be modified by pigmentation characteristics

    Protective behavior of radiological technologists against radiation exposure is important to achieve reduction of the patient doses without compromising medical achievements. This study attempts to provide a basic model for the sophisticated intervention strategy that increases the level of the protective behavior of the technologists. The model was applied to real situations in Korea to demonstrate its utility. The results of this study are summarized as follows: First, the protective environment showed the highest relationship in the factors considered, r=0.637 (p<0.01). Secondly, the important factors were protective environment in environment characteristics, expectation for the protective behavior 0.228 (p<0.001), self efficacy 0.142 (p<0.001), and attitude for the protective behavior 0.178 (p<0.001) in personal characteristics, and daily patient -0.112 (p<0.001) and number of the participation in the education session for the protective behavior 0.074 (p<0.05). Thirdly, the final protective behavior model by a path analysis method had direct influence on the attitude 0.171 (p<0.01) and environment 0.405 (p<0.01) for the protective behavior, self efficacy 0.122 (p<0.01), expectation for the protective behavior 0.16 (p<0.01), and self-efficacy in the specialty of projects 0.154 (p<0.01). The acceptance of the model determined by the absolute fit index (GFI), 0.969, and by the incremental fit index (CFI), 0.943, showed very significant levels. Value of 2/df that is a factor applied to verify the acceptance of the model was 37, which implies that the result can be accepted in the desirable range. In addition, the parsimonious fit index configured by AGFI (0.890) and TLI (0.852) was also considered as a scale that accepts the model in practical applications. In case of the establishment of some specific intervention strategies based on the protective behavior model against harmful radiation effects proposed in this study, the strategy will provide an effective way

    The use of radiology examinations in medicine has been growing worldwide. Annually an estimated 3.1 billion radiologic exams are performed. According to this expansion of medical radiation exposure, it has been hard to pay no attention to the effects of medical radiation exposures in the exposure from different types of radiation source. This study, therefore, was aimed to assess the association of medical and occupational radiation exposure in Korean radiologic technologists and evaluate necessity for its consideration in occupational studies. This study did not show the strong association between medical radiation exposure and occupational radiation exposure except several modalities with specific frequency. These results are preliminary but certainly meaningful for interpretation of epidemiologic finding, therefore, we need further evaluation specially for the repeatedly exposed imaging tests and high dose procedures that presented somewhat weak relationship in this study linked with health outcomes of radiation exposure. This study did not show the strong association between medical radiation exposure and occupational radiation exposure except several modalities with specific frequency. These results are preliminary but certainly meaningful for interpretation of epidemiologic finding, therefore, we need further evaluation specially for the repeatedly exposed imaging tests and high dose procedures that presented somewhat weak relationship in this study linked with health outcomes of radiation exposure.

    There has been great concern regarding the radiation protection for women of reproductive age when exposed to diagnostic radiation. The 10-day-rule proposed by the ICRP has not been recommended since 1983 because the risk to embryo and fetus within four weeks after menstruation may be small. However, some expects see that incomplete abandon of the 10-day-rule might cause confusion among the medical doctors and patients, and consequently unwarranted abortion happens. This paper surveyed the views of radiation technologies in hospitals and discussed how radiation exposure of women of reproductive age in medicine should be controlled. We found that the views to be 10-day-rule were spilt 50:50 and that radiation technologists do not necessarily think the 10-day-rule should be abandoned. Even the radiation technologists who are supposed to be able to explain to the patients the health risk following diagnostic exposure do not fully understand the risk involved. In conclusion, although a low-dose risk of diagnostic exposure should be sufficiently educated in order to obtain an exact understanding, the 10-day-rule may be useful in order to actually avoid any trouble in diagnostic radiology.

Method: A questionnaire was used to collect data from 261 radiological technologists working in the city of Busan. Then, SPSS/PC + Win 13 was used to statistically analyze the collected data. One-way ANOVA was adopted to test differences among groups, and multiple regression analyses were conducted to examine the effect of organizational culture and leadership upon organizational effectiveness. Results: First, it was found that radiological technologists stressed consensus most among the 4 types of organizational culture and regarded core transformational leadership as the right type of leadership. Second, regarding the relationship between leadership and organizational effectiveness, transformational leadership had the highest influence upon organizational effectiveness. Third, as for the relationship between organizational culture and organizational effectiveness, it was found that a developmental culture has the highest influence upon organizational effectiveness, followed by a culture of consensus. Conclusion: If transformational leadership and consensual culture are used properly for upgrading job performance in the organization, conflicts among radiological technologists might be reduced, thereby enhancing organizational effectiveness.

    Although the implementation of picture archiving and communication system (PACS) could increase productivity of radiology departments, this depends on factors such as the PACS competence of radiologic technologists (RTs). The purpose of this study was to investigate the RTs' perceptions of PACS competence and educational issues in Western Australia (WA). A hardcopy questionnaire was distributed to WA RTs for obtaining their perceptions of PACS competence and educational issues. Descriptive (percentage of frequency, mean and standard deviation) and inferential statistics (t test and analysis of variance) were used to analyze the responses of the multiple choice and five-point scale questions from the returned questionnaires. The questionnaire response rate was 57.7% (173 out of 300). The mean values of all PACS competence questions except questions 2e-g are in the range of 3.9-4.9, i.e., around competent to very competent. Participants indicated they received adequate PACS training (mean 3.8). Statistically significant variables influencing RTs' perceptions of their PACS competence and educational issues including the age (p education received (p system, and received adequate training. However, future PACS education programs should be tailored to different RTs' groups. For example, multiple training modules might be necessary to support the PACS competence development of older RTs and those with lower general computer literacy.

    Radiological Technologists deals with the life of a person which means professional competency is essential for the job. Nevertheless, there have been no studies in Korea that identified the job competence of radiologists. In order to define the core job competencies of Korean radiologists and to present the factor models, 147 questionnaires on job competency of radiology were analyzed using 'PASW Statistics Version 18.0' and 'AMOS Version 18.0'. The valid model consisted of five core job competencies ('Patient management', 'Health and safety', 'Operation of equipment', 'Procedures and management') and 17 sub – competencies. As a result of the factor analysis, the RMSEA value was 0.1 and the CFI, and TLI values were close to 0.9 in the measurement model of the five core job competencies. The validity analysis showed that the mean variance extraction was 0.5 or more and the conceptual reliability value was 0.7 or more , And there was a high correlation between subordinate competencies included in each subordinate competencies. The results of this study are expected to provide specific information necessary for the training and management of human resources centered on competence by clearly showing the job competence required for radiologists in Korea's health environment.

    In this study, we surveyed the current status, satisfaction and demand of radiologic technologist continuing education for 93 radiologic technologists who participated in the continuing education. To understand the current status and general evaluation and to find out the improvement direction, survey was conducted on 3 categories: participation, satisfaction and demand of continuing education. In addition, we analyzed the continuing education implementation status and the management system by collecting related regulations. As a result, the education completion rates of radiologic technologists from 2010 to 2012 were respectively 42.6%, 43.4% and 34.2%; the rates were similar to other medical technician’s average education completion rates. According to the survey, in case of participation, the most frequent answer was ‘more than five times less than 10 times per year’ with 48.4% and in satisfaction section, the most common answer was ‘Average(3)’ with 34.4%. In demand of continuing education section, 32.8% of the respondents chose ‘Clinical skill training in major field’. In the results of this research, continuing education needs to be managed in the direction of helping radiologists improve their personal ability and self development. Furthermore, to meet the demand of radiologists, the quality of continuing education should be improved to satisfy the educatee

    In order to examine how Radiological Technologists perceive the oriental doctor's use of Medical Imaging Equipment, surveys were conducted for the members of the Korean Radiological Technologists Association. The total number of respondents were 515 and 481, with 34 insincere responses removed caused of nonvalidated answer. The results of the analysis are as follows. Although there were no statistical significance in the difference in perception by location of residence, work place, and educational background, respondents with higher education showed a tendency to agree on the use of comprehensive medical imaging equipment, but tended to oppose the use of special medical imaging equipment. Differences in perception by gender showed a greater negative perception toward the oriental doctor's use of medical imaging equipment by women than men. In particular, women showed more negative tendency for oriental doctor's use of special medical imaging equipment such as MRI, CT, and ultrasound equipment compared to men, and this was statistically significant. The difference in perception by age showed that the oriental doctor's use of medical imaging equipment was negative in the 20∼30s, neutral in the 40∼50s, and positive in the 60s, which were statistically significant. The difference in perception by work experience showed that the longer the work experience was, the more positive it was toward oriental doctor's use of medical imaging equipment. Specifically, the most favorable tendency was found with work experience of more than 30 years, which was statistically significant. The results of this study revealed the Radiological Technologists' perceptions on the oriental doctor's use of Medical Imaging Equipment and this can contribute to the direction of public health promotion in the future

    This technical innovation describes the development of a novel device to aid technologists in reducing exposure variation and repeat imaging in computed and digital radiography. The device consists of a color video and depth camera in combination with proprietary software and user interface. A monitor in the x-ray control room displays the position of the patient in real time with respect to automatic exposure control chambers and image receptor area. The thickness of the body part of interest is automatically displayed along with a motion indicator for the examined body part. The aim is to provide an automatic measurement of patient thickness to set the x-ray technique and to assist the technologist in detecting errors in positioning and motion before the patient is exposed. The device has the potential to reduce the incidence of repeat imaging by addressing problems technologists encounter daily during the acquisition of radiographs. (orig.)

    To elucidate the effects of long-term exposure to low dose irradiation, serostatus of antibodies to cytomegalovirus (CMV), Epstein-Barr virus (EBV) and human T cell lymphotropic virus type 1 (HTLV-1) was determined in 99 radiological technologists and 96 healthy volunteers. Abnormal seropositivity rate for CMV was significantly higher in technologists working for 15 years or more than in those working for less than 15 years. For the same age group, however, there was no significant difference between technologists and controls. Seropositivity rates for EBV-viral capsid antigen (VSA)/IgG and early antigen (EA)/IgG were significantly higher in technologists working for 15 years or more than in the age-matched control group. In the group of technologists exposed to 0.3 Sv or more, seropositivity rates of these antibodies were significantly higher than in those exposed to less than 0.3 Sv. However, there was no correlation between exposure doses and both EBV-associated nuclear antigen antibody and HTLV-1 antibody. Few technologists seronegative for CMV antibody had seropositive antibodies of EBV-VCA/IgG and EA/IgG. For technologists seropositive for CMV antibody, 31% and 54% were seropositive for EBV-VCA/IgG and EA/IgG antibodies, respectively. (Namekawa, K).

    This study aimed to assess whether the changes in compliance rates of evaluation criteria after healthcare accreditation among radiologic technologists working at four university hospitals which had acquired healthcare accreditation in Daejeon metropolitan area. In this study, the evaluation criteria of healthcare accreditation were reclassified and reevaluated to three areas which include patient safety, staff safety, and environmental safety. Each area has eight, three, and five questions, respectively. Each compliance rate was quantitatively measured on a scale of 0 to 10 before and after in this study. The result shows that the overall compliance rates were decreased on all areas compared to the time healthcare accreditation was obtained. The compliance rate of hand hygiene was drastically reduced. To maintain the compliance rates, not only individuals but healthcare organizations should simultaneously endeavor. In particular, healthcare organizations should make an effort to provide continuous education opportunity to their workers and supervise the compliance regularly

    Chromosomal aberrations in the lymphocytes of radiation technologists (RT) were analyzed by the trypsin G-banding method to study the late effects of long-term exposure to low doses of radiation. Structural aberrations were identified in 384 (2.5%) of 15442 cells analyzed from 53 RT as compared to 177 (1.6%) of 11136 cells from 36 healthy controls. Stable aberrations were the most frequent in both groups and were either translocations or deletions. Unstable aberrations were mainly acentric fragments in both groups. The frequency of translocations and acentric fragments was significantly higher in the RT than in the controls and was highest in the RT over 50 years. The highest frequency observed in the >50 age group was attributed to the unknown for cumulative dose prior to introduction of film badges. Frequency of chromosomal aberrations correlated with the estimated dose from the film badges and years of experience of each RT based on the equation y=0.22+0.37D+4.35D 2 , where y is overall frequency of chromosomal aberrations and D is the estimated radiation dose in Sv.

    This article is an information for radiation protection experts. In Austria 2013, seven new jobs were enshrined in ''medical assistance law''. One is the X-ray assistant (Radiographic Assistant). The X-ray assistant may perform simple standardized radiographs. It represents the lowest common denominator to the profession ''Radiologic Technology''. This post will serve experts for radiation protection and employers to inform objectively about which profession has the competences and in which field of work X-ray assistants can be deployed. This article deals with the course content and the classification in the European Qualifications Framework and the legal anchorages.

    Purpose: To determine if the flipped class format has an effect on examination results for a radiologic technologist (RT) program and discuss benefits from creating video resources. Methods: From 2001–2015, students had taken both a radiological physics and quality control (QC) class as a part of their didactic training. In 2005/2006, the creation of videos of didactic lectures and QC test demonstrations allowed for a flip where content was studied at home while exercises and reviews were done in-class. Final examinations were retrospectively reviewed from this timeframe. 12 multiple choice physics questions (MCP) and 5 short answer QC questions (SAQC) were common to pre and post flip exams. The RT program’s ARRT exam scores were also obtained and compared to national averages. Results: In total, 36 lecture videos and 65 quality control videos were created for the flipped content. Data was ∼2.4GB and distributed to students via USB or CD media. For MCP questions, scores improved by 7.9% with the flipped format and significance (Student’s t-test, p<0.05) was found for 3 of the 12 questions. SAQC questions showed improvement by 14.6% and significance was found for 2 of the 5 questions. Student enrollment increased from ∼14 (2001–2004) to ∼23 students (2005–15). Content was continuously added post-flip due to the efficiency of delivery. The QC class in 2003 covered 45 test setups in-class while 65 were covered with video segments in 2014. Flipped materials are currently being repurposed. In 2015, this video content was restructured into an ARRT exam review guide and in 2016, the content was reorganized for fluoroscopy training for physicians. Conclusion: We believe that flipped classes can improve efficiency of content delivery and improve student performance even with an increase in class size. This format allows for flexibility in learning as well as re-use in multiple applications.

    To clarify the long-term effects of occupational exposure to low doses of radiation, Epstein-Barr virus (EBV)-specific antibody titers in sera from 104 radiological technologists (R.T.) and 118 controls in Kumamoto prefecture were measured by the immunofluorescence method. Antibody titers to viral capsid antigen (VCA)-IgG increased with the years of experience as R.T., and the prevalence of abnormal antibody titers to both VCA-IgG and early antigen (EA)-IgG were significantly higher in R.T. with over 15 years of experience or 30 rads of cumulative radiation dose than in the controls. However, there was no correlation between exposure and the frequency of abnormal EBV-associated nuclear antigen (EBNA) antibody titers. The EBV-specific antibody titers of 24 Hiroshima atomic-bomb survivors were also measured. They were similar to those of the R.T. with over 30 years of experience. The EBV-specific antibody titers of R.T. suggest that there may be an impairment of immunologic competence after continuous long-term exposure to low doses of radiation. Also, the correlation of EBV-specific antibody titers and frequency of cells with chromosome aberrations in 53 R.T. was studied. Some correlations were found between the antibody titers to both of the VCA-IgG and EBNA and the frequency of cells with chromosome aberrations.

    The Aichi Association of Radiological Technologists executed the survey according to the task of radiation control in Aichi prefecture. The survey investigated the number of clinics/hospitals who own radiation dosimeters. The association also measured outputs using glass dosimeter (GD-450) manufactured by Chiyoda Technical in diagnostic X ray. The purpose and significance of the survey are: to illustrate that the radiation control task is not involved as routine maintenance work, to examine why the task is not routinely performed, to investigate the number of clinics/hospitals who own diagnostic X ray radiation dosimeters, to inform that the use of dosimeter is essential to achieve accurate measurement for exposed dose, and to motivate the significance of radiation control in routine work. The result of the survey clearly indicated the necessity of radiation control, and suggested the information needed for the Aichi Association of Radiological Technologists to determine the guideline for the medical radiation exposed dose.

    Full Text Available Background: It is of critical importance to improve and maintain the quality of chest radiography (CXR to avoid faulty diagnosis of respiratory diseases. The study aims to determine the effectiveness of a training program in improving the quality of CXR among radiological technologists (RTs in Laos. Design: This was a cross-sectional study, conducted through on-site investigation of X-ray facilities, assessment of CXR films in Laos, both before and after a training course in November 2013. Methods: Each RT prospectively selected 6 recent CXR films, taken both before and within approximately 6 months of attending the training course. Consequently, 12 CXR films per RT were supposed to be collected for assessment. The quality of the CXR films was assessed using the “Assessment Sheet for Imaging Quality of Chest Radiography.” Results: Nineteen RTs from 19 facilities at 16 provinces in Laos participated in the training course. Among them, 17 RTs submitted the required set of CXR films (total: 204 films. A wide range of X-ray machine settings had been used as tube voltage ranged from 40 to 130 kV. The assessment of the CXR films indicated that the training was effective in improving the CXR quality regarding contrast (P = 0.005, sharpness (P = 0.004, and the total score on the 6 assessment factors (P = 0.009. Conclusions: The significant improvement in the total score on the 6 assessment factors, in contrast, and in sharpness, strongly suggests that the training course had a positive impact on the quality of CXR among a sample trainees of RTs in Laos.

    The Japan Association of Radiologic Technologists reported that, from 1941 to 1978, 395 deaths occurred among Japanese radiological technologists who belong to the association. Using these data, Sakka, Kitabatake and colleagues, and the present authors studied mortality and cause of death among these technologists for 11 years from 1955 to 1965, for 7 years from 1966 to 1972, and for 5 years from 1973 to 1977, respectively. In general, the number of cancer deaths in the three studies was less than expected. However, Kitabatake et al. and the present authors found that deaths from skin cancer were significantly more frequent than expected. The present authors recently estimated the cumulative doses of radiation exposure for the majority of deaths (268 out of 395). The mean dose of radiation related to cancer deaths was then compared with that for non-cancer deaths. Also the proportional mortality ratios for cancers were observed in relation to the estimated dose level. In the present study, however, statistical tests to assess for the relationship between mortality and dose of radiation exposure showed no correlation, for the majority of deaths from cancer.

    Ionizing radiations are used in areas such as health, industry and safety, not only in the private sector, but also in the public. Thus, it is necessary the radiological protection, a set of studies and practices that increases the safety in these applications, where the professional involved is the technologist in radiology. The objective was to analyze the contents effectively required by the Brazilian public agencies in their competitions for radiology technologist, regarding the area of radiological protection, identifying their profile of requirement. It consisted of three stages: first, a survey of all the public competitions already carried out in the country up to the end of 2016, that requested a diploma of graduation in Technology in Radiology; second, all the specific questions were collected and grouped in an electronic text file; third, issues involving radiological protection were segregated, using as reference the 2017 edition of the National Nuclear Energy Commission's General Proof of Radioprotection Supervision. The results showed that almost 40% of the competition questions were about radiation protection. From this sampling, the topics most covered were: radiological safety (36%), fundamentals of atomic and nuclear physics (24%) and biological effects of radiation (16%). It is concluded that the competitions for radiologist technologist have the profile of concentration of exigency in radiological safety, fundamentals of atomic and nuclear physics and biological effects of the radiations.

    2007-01-01

    Development of hospital information system and Picture Archiving Communication System is not new in the medical field, and the development of internet and information technology are also universal. In the course of such development, however, it is hard to share medical information without a refined standard format. Especially in the department of radiology, the role of PACS has become very important in interchanging information with other disparate hospital information systems. A specific system needs to be developed that radiological reports are archived into a database efficiently. This includes sharing of medical images. A model is suggested in this study in which an internal system is developed where radiologists store necessary images and transmit them is the standard international clinical format, Clinical Document Architecture, and share the information with hospitals. CDA document generator was made to generate a new file format and separate the existing storage system from the new system. This was to ensure the access to required data in XML documents. The model presented in this study added a process where crucial images in reading are inserted in the CDA radiological report generator. Therefore, this study suggests a storage and transmission model for CDA documents, which is different from the existing DICOM SR. Radiological reports could be better shared, when the application function for inserting images and the analysis of standard clinical terms are completed

    This study investigated the realities of information acquirements and its requirements in the overseas employment and domestic connected education for students at the department of radiation in order to provide basic information for developing the standard educational curriculum for future internationalization in the education of radiation and presenting its direction. The investigation implemented in this study was performed through a questionnaire with 688 students enrolled in the department of radiation. The conclusion of the investigation is summarized as follows : The answers for the question of 'No acquirements in the information of the overseas employment and connected education for radiological technologists' were 487 students (70.8%), and the reason that 'There are no chances in related education' was the highest rate, 424 students (61.6%), of the answers. In the education for the overseas employment, the answers for the question of 'Select a connected education program in school instead of study abroad' were the highest rate, 436 students (63.4%). The most concerned country for the overseas employment was 'Australia', 247 students (35.9%). As a result, answers for the interest, participation, need, and hope for the overseas employment showed high rates even though they demonstrated a low recognition level in the overseas employment. In addition, it is necessary to strategically plan an education program for this issue because all participants agree with the current stream.

    Rationale and Objectives: In Emergency Departments (ED) junior doctors regularly make diagnostic decisions based on radiographic images. This study investigates whether collaboration between junior doctors and radiographers impacts on diagnostic accuracy. Materials and Methods: Research was carried out in the ED of a university teaching hospital and included 10 pairs of participants. Radiographers and junior doctors were shown 42 wrist radiographs and 40 CT Brains and were asked for their level of confidence of the presence or absence of distal radius fractures or fresh intracranial bleeds respectively using ViewDEX software, first working alone and then in pairs. Receiver Operating Characteristic was used to analyze performance. Results were compared using one-way analysis of variance. Results: The results showed statistically significant improvements in the Area Under the Curve (AUC) of the junior doctors when working with the radiographers for both sets of images (wrist and CT) treated as random readers and cases (p ≤ 0.008 and p ≤ 0.0026 respectively). While the radiographers’ results saw no significant changes, their mean Az values did show an increasing trend when working in collaboration. Conclusion: Improvement in performance of junior doctors following collaboration strongly suggests changes in the potential to improve accuracy of patient diagnosis and therefore patient care. Further training for junior doctors in the interpretation of diagnostic images should also be considered. Decision making of junior doctors was positively impacted on after introducing the opinion of a radiographer. Collaboration exceeds the sum of the parts; the two professions are better together.

    In this textbook, the emphasis is less on conventional X-ray techniques of proven value than on more recently developed methods of medical imaging like computed tomography and magnetic resonance tomography. The strategies currently followed in the initial diagnosis, rather than invariably relying on the X-ray methods of the past, are to an increasing extent based on innovative technologies. A considerable part of the textbook is basically an attempt at surveying the contributions of the individual radiologic and radionuclide methods to the establishment of a firm diagnosis. It is pointed out that one single method may provide just one single piece of information. Pathologic changes often can only be assessed in detail, if the individual results of various tests are assembled to make up a complete picture. A limited range of tools and basic reliance on one method alone may detract from diagnositc accuracy. (orig./MG) With 300 figs., 5 tabs [de

    1985-01-01

    This paper discusses the role of the technologist in helping achieve all the objectives of the nuclear project - not only the technical objectives, but the business and societal objectives as well. It is important to realize at the outset the many objectives that the project can fulfill, including the contribution it can make to national development. The technologist may act as consultant, a partner, a business administrator or an agent of the utility, helping implement a management approach that furthers not only technical, but business and societal objectives as well. Two very different approaches to contracting are possible. On the one hand, the utility places heavy pressure on bidders to accept the risk of schedule and license, and forces suppliers to charge higher prices and make little use of local talent. On the other hand, the utility may recognize the need to develop national capability in the nuclear industry, and accept cooperative contracts which encourage suppliers to foster and employ local talent. This issue must be given attention in the initiation of future national nuclear power programs: whether to minimize the cost of the plant or maximize the cultivation and development of national capability

    Although large medical texts are stored in electronic format, they are seldom reused because of the difficulty of processing narrative texts by computer. Morphological analysis is a key technology for extracting medical terms correctly and automatically. This process parses a sentence into its smallest unit, the morpheme. Phrases consisting of two or more technical terms, however, cause morphological analysis software to fail in parsing the sentence and output unprocessed terms as "unknown words." The purpose of this study was to reduce the number of unknown words in medical narrative text processing. The results of parsing the text with additional dictionaries were compared with the analysis of the number of unknown words in the national examination for radiologists. The ratio of unknown words was reduced 1.0% to 0.36% by adding terminologies of radiological technology, MeSH, and ICD-10 labels. The terminology of radiological technology was the most effective resource, being reduced by 0.62%. This result clearly showed the necessity of additional dictionary selection and trends in unknown words. The potential for this investigation is to make available a large body of clinical information that would otherwise be inaccessible for applications other than manual health care review by personnel.

    To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

    Purpose: To determine the economic efficiency of a whole-radiology in- and outpatient treatment with angiographic interventions performed as the main or sole therapy. Materials and Methods: The calculations represent the data of a university radiology department, including the following angiographic interventions (neuroradiology not considered): Vascular intervention (PTA, stent implantation) of kidneys and extremities, recanalization of hemodialysis access, chemoembolization, diagnostic arterioportal liver CT, port implantation, varicocele embolization, PTCD, percutaneous implantation of biliary stent. First, the different angiographic interventions are categorized with reference to the German DRG system 2005. Considering the example of a university hospital, the individual cost of each intervention is calculated and correlated with reimbursements by G-DRG2005 and so-called ''ambulant operation'' (EBM200plus). With these data, profits and losses are calculated for both in- and outpatient care. Results: Radiologic interventions of inpatients yield a profit in the majority of cases. With a base rate of 2900 Euro, the profits in our university hospital range between -872 Euro and +3411 Euro (mean: +1348 Euro). On the other hand, those angiographic interventions suitable for ''ambulant operation'' generate average profits of +372 Euro, if only direct costs are considered. The data of outpatient radiological interventions average between 381 Euro up to 1612 Euro lower than compared with profits obtained from in patient care. (orig.)

    Radiological diagnosis of pulmonary sequestration: review of six cases, including one bilateral. Pulmonary sequestration is an uncommon disorder consisting of aberrant pulmonary tissue that has no normal connection with the bronchial tree or with the pulmonary arteries, but is supplied by a systemic artery which usually arises from the aorta. Six cases of pulmonary sequestration are presented and the radiological manifestation of this rare congenital disorder are discussed. These sequestrations were intralobar/unilateral in four patients, extralobar/unilateral in one and extralobar/bilateral in the other patient. Special attention is given to the extremely uncommon bilateral sequestration. To our knowledge only four cases of this form of disease has been described in the literature. (author) [pt

    This paper develops a relative scale of value for pediatric radiology (RSVPR). Neither the HCFA/ACA Relative Value Scale nor the Workload Measurement System developed by Health and Welfare Canada specifically addressed pediatric radiologic examinations. Technical and professional charges for examinations at Children's Hospital Medical Center were reviewed and compared with time and cost analysis. A scale was developed with chest radiography (PA and lateral views) assigned a value of 1. After review by pediatric radiologic technologists, radiologic administrators, pediatric radiologists, and chairs of departments of children's hospitals, this proposed scale was modified to reflect more accurately relative value components of pediatric radiologic and imaging examinations

    Full text: The purpose is to present the activities of Department of Radiation technologists at Medical College Sofia in knowledge management (KM) in human health applications and namely: continuous development of academic curriculum (AC) for medical radiation technologists (MRT) in sense of the conference motto “Nuclear Knowledge Management: Challenges and Approaches”. Our challenge is to realize, in practice, the important role of MRT professionals in healthcare. They are the front line in the patient safety and the last person with the patient before exposure. The existing AC has been periodically peer-reviewed: in 2011, 2014, and ongoing reviews, with the aim to guarantee that we are providing knowledge, skills and competencies that meet modern requirements for the training of radiation technologists. The AC compromises both academic and clinical education. The clinical component occurs throughout the academic course, accenting the role of MRT in radiology, radiotherapy and nuclear medicine. The approach of continuously developing the AC will meet the stringent requirements recently published by IAEA, with the goal that radiological medical practitioners, medical physicists, medical radiation technologists and other health professionals with specific duties in relation to protection and safety for patients in a given radiological procedure are specialized in the appropriate area.

    Clinical post-mortem radiology is a relatively new field of expertise and not common practice in most hospitals yet. With the declining numbers of autopsies and increasing demand for quality control of clinical care, post-mortem radiology can offer a solution, or at least be complementary. A working group consisting of radiologists, pathologists and other clinical medical specialists reviewed and evaluated the literature on the diagnostic value of post-mortem conventional radiography (CR), ultrasonography, computed tomography (PMCT), magnetic resonance imaging (PMMRI), and minimally invasive autopsy (MIA). Evidence tables were built and subsequently a Dutch national evidence-based guideline for post-mortem radiology was developed. We present this evaluation of the radiological modalities in a clinical post-mortem setting, including MIA, as well as the recently published Dutch guidelines for post-mortem radiology in foetuses, neonates, and children. In general, for post-mortem radiology modalities, PMMRI is the modality of choice in foetuses, neonates, and infants, whereas PMCT is advised in older children. There is a limited role for post-mortem CR and ultrasonography. In most cases, conventional autopsy will remain the diagnostic method of choice. Based on a literature review and clinical expertise, an evidence-based guideline was developed for post-mortem radiology of foetal, neonatal, and paediatric patients. What is Known: • Post-mortem investigations serve as a quality check for the provided health care and are important for reliable epidemiological registration. • Post-mortem radiology, sometimes combined with minimally invasive techniques, is considered as an adjunct or alternative to autopsy. What is New: • We present the Dutch guidelines for post-mortem radiology in foetuses, neonates and children. • Autopsy remains the reference standard, however minimal invasive autopsy with a skeletal survey, post-mortem computed tomography, or post

    One hundred seven patients who underwent procedures not involving direct interaction with a radiologist were interviewed regarding their experience. The 545 responses divided clearly into items regarding the physical facility (parking, room temperature, etc) and items directly under control of radiology. The latter were twofold: waiting time and technologist behavior. Specific behaviors judged critical for technologists included ability to impart clear instructions, interpersonal behaviors, concern for physical comfort, and skill in procedure performance. A final question involved the role of the ''unseen'' radiologist. Patients desired a high level of skill in study interpretation and that the radiologist possess several positive personality traits even though they never anticipated direct contact

    Full Text Available This article explores how the role of learning technologists, a professional group that has emerged during the last 15 to 20 years, may be diversifying to include supporting e-research. It contributes to the current debate about the emerging profession and the roles it should play in contemporary higher education. Previous studies have shown that, typically, the profession's role has focussed almost exclusively on curriculum development; traditionally, learning technologists work with students and tutors to enhance the learning environment with technology. This article presents two case studies of PhD research that used a standard e-learning tool, the virtual learning environment (VLE, to conduct focus groups online. The case studies demonstrate the expert role of the learning technologist in supporting researchers to make informed decisions about whether and how to use e-learning tools to conduct qualitative e-research. The learning technologist advised on the potential advantages and limitations of using the VLE for research and fostered collaborative, working relationships with the researchers, acquiring extensive background knowledge about their projects. This required the learning technologist to draw upon her own experience with research into e-learning and on her professional experience gained from supporting curriculum developments. It is suggested that many learning technologists could extend their roles, transferring their knowledge to include supporting e-research. A more inclusive model of the learning technologist's role in academia could help address the potential polarisation of the profession into researchers and practitioners.

    To assess how the portrayal of Radiology on medical TV shows is perceived by patients and radiology professionals. In this IRB-approved study with patient consent waived, surveys were conducted among adult patients scheduled for radiological examinations and radiology professionals. The questionnaire investigated medical TV watching habits including interest in medical TV shows, appearance of radiological examination/staff, radiology's role in diagnosis-making, and rating of the shows' accuracy in portraying radiology relative to reality. One hundred and twenty-six patients and 240 professionals (133 technologists, 107 radiologists) participated. 63.5 % patients and 63.2 % technologists rated interest in medical TV shows ≥5 (scale 1-10) versus 38.3 % of radiologists. All groups noted regular (every 2nd/3rd show) to >1/show appearance of radiological examinations in 58.5-88.2 % compared to 21.0-46.2 % for radiological staff appearance. Radiology played a role in diagnosis-making regularly to >1/show in 45.3-52.6 %. There is a positive correlation for interest in medical TV and the perception that radiology is accurately portrayed for patients (r = 0.49; P = 0.001) and technologists (r = 0.38; P = 0.001) but not for radiologists (r = 0.01). The majority of patients perceive the portrayed content as accurate. Radiologists should be aware of this cultivation effect to understand their patients' behaviour which may create false expectations towards radiological examinations and potential safety hazards.

    To evaluate scientific papers published by Korean radiologists in the Science Citation Index Expanded (SCIE) radiology journals, between 1986 and 2010. The Institute for Scientific Information Web of Knowledge-Web of Science (SCIE) database was searched for all articles published by Korean radiologists, in SCIE radiology journals, between 1986 and 2010. We performed the analysis by typing 'Korea' and 'radiol' in the address section and selecting the subject area of 'Radiology, Nuclear Medicine, and Medical Imaging' with the use of the general search function of the software. Analyzed parameters included the total number of publications, document types, journals, and institutions. In addition, we analyzed where Korea ranks, compared to other countries, in terms of the number of published articles. All these data were analyzed according to five time periods: 1986-1990, 1991-1995, 1996-2000, 2001-2005, and 2006-2010. Overall, 4974 papers were published by Korean radiologists, in 99 different SCIE journals, between 1986 and 2010, of which 4237 (85.2%) were article-type papers. Of the total 115395 articles, worldwide, published in radiology journals, Korea's share was 3.7%, with an upward trend over time (p < 0.005). The journal with the highest number of articles was the American Journal of Roentgenology (n 565, 13.3%). The institution which produced the highest number of publications was Seoul National University (n = 932, 22.0%). The number of scientific articles published by Korean radiologists in the SCIE radiology journals has increased significantly between 1986 and 2010. Korea was ranked 4th among countries contributing to radiology research during the last 5 years.

    Diagnostic radiology is still the foremost of all innovative medical disciplines. This has many advantages but also some handicaps, e.g. the siting problem of medical equipment whose clinical potential is not fully known. This applies in particular to nuclear spin tomography, where the Laender governments and the Scientific Council seen to agree that all universities should have the appropriate equipment as soon as possible in order to intensify interdisciplinary research. Formerly, in the case of computerized tomography, there was less readiness. As a result, the siting of CT equipment is less organically structured. A special handicap of innovative fields is the problem of training and advanced training. The Chamber of Medicine and the Association of Doctors Participating in the Health Insurance Plan have issued regulations aimed at a better standardisation in this field. (orig.) [de

    Full text: Nuclear medicine has contributed to notable benefits to the human health from the very beginning. The Radioisotopes techniques, as well as the ionizing radiation used, have evolved providing functional and anatomical information of the patient, through non-invasive methods. With reference to Radiological Protection, the justification of each one of these practices and its perfect execution is intimately related to the benefit provided to the patients. The National Atomic Energy Commission apart from favouring the scientific and technological development, considers indispensable to work thoroughly on the professional training of the prospective technologists. Our over twenty-year experience in organizing and delivering courses of Technologists in Nuclear Medicine, although based on a much simpler program, have allowed the Institute of Nuclear Studies of the Ezeiza Atomic Center to acquire the capacity of developing a program to train highly qualified Technologists in that field. This project represents a step forward of great importance to the graduates qualification, since they will have the endorsement of CNEA and of the Faculty of Medicine of the Maimonides University. These are the three outstanding characteristics agreed on: 1.- General Education, carried out by subjects closely related to the optimisation of the relation Technologist - Patient - Environment and represented by: Radiological Protection and Hospital Security, Psychology, Ethics and Professional Medical Ethics, Nursing, English, Hygiene and Hospital Security and Management of the Quality in Services of Health. 2.- Diagnostic Procedures: planned according to organs, apparatuses or systems which are horizontally crossed by the anatomy, physiology and physiopathology Preparation of the patient, indications, main counter indications, radiopharmaceuticals, mechanisms of incorporation, pathologies, clinical protocols, instrumentation, post radiopharmaceuticals administration imaging

    In 1997 the European Commission published Radiation Protection 91: 'Criteria for acceptability of radiological (including radiotherapy) and nuclear medicine installations'(1). This document specified the minimum criteria for acceptability. It has been used to this effect in legislation, codes of practice and by individual professionals. In a single document, it defined a level of performance at which remedial action was required. The document specified a series of parameters which characterised equipment performance and acceptable levels of performance. In its time it proved to be a useful document which was applied in member states to various degrees. Since the publication of Report 91 in 1997(1), a series of weaknesses emerged over time. Development of new radiological systems and technologies, as well as improvements in traditional technologies, has created circumstances where the acceptability criteria were in need of review. These weaknesses were recognised by the European Commission and a tender for its revision was issued. The criteria were developed by a team drawn from a broad range of backgrounds including hospitals, industry, government bodies, regulators and standardisation organisations. Representatives were mainly from Europe, but individuals from the American Association of Physicists in Medicine and International Atomic Energy Agency were included in the drafting process. This study describes the process employed in developing the revised document and the consultation process involved. One of the major difficulties the revision team encountered was related to an understanding of the actual meaning of the EC Directive(2). The view taken by the revision team was that Article 8, paragraph 3 places responsibilities on both the holders of radiological equipment and competent authorities. The acceptability criteria have been produced consistent with the European Commission's Medical Exposures Directive(2), which requires that patient exposures are

    Full Text Available Osteitis deformans or Paget′s disease of bone, fondly referred to as the ′collage of matrix madness′, is a unique skeletal disease characterized by furious osteoclastic bone resorption followed by a period of hectic bone formation, resulting in again in the bone mass wherein the newly formed bone is disordered and architecturally unsound. A disease of obscure etiology, it usually manifests as progressive enlargement of one or multiple bones of the skeleton. Herewith we present a typical example of a polyostotic form of Paget′s disease with classical clinical features and radiologic changes in one patient and a subclinical form of Paget′s disease with marked radiological changes in the other patient.

  18. Professional liability of the radon technologist

    Kornreich, M.R.

    1987-01-01

    The radon technologist will want to protect himself from lawsuits by plaintiffs who believe they have suffered consequences of a false measurement or erroneous recommendation. The author may be sued for negligence or on the contract. A plaintiff is more likely to be successful in a suit for monetary losses associated with real estate transactions or remediation than in a suit for personal injury. To avoid liability, the radon technologist will want to keep aware of the state of the art; use standard protocols; carefully supervise employees; take all technical precaution; and get legal advice in contracting. The author should also adhere to applicable federal, state, or local regulations. Disclosing the limits of measurement procedures and emphasizing the importance of maintaining standardized environmental conditions in the building are important. Since it is extremely difficult for an individual to get adequate professional liability insurance at a reasonable price, radon technologists should cooperate, perhaps through their professional societies, to negotiate the best possible insurance policies

    We aimed to analyze scientific papers published by Turkish authors in "radiology, nuclear medicine and medical imaging" journals included in the Science Citation Index Expanded and compared the number of published scientific papers from Turkey and other countries. We retrospectively searched all papers published by Turkish authors between 1945 and 2008 by using Web of Science software. We performed the analysis by typing "Turkey" in the address section and all radiology and medical imaging journals in the source title section using the general search function of the software. We further analyzed these results by using "analyze" function of the software according to the number of publications per year, journals, institution and type of papers. We also calculated total number of citations to published scientific papers using citation report function. We analyzed the rank of Turkey among other countries in terms of the number of published papers. Overall, 4,532 papers were published between 1945 and 2008. The first paper was published in 1976. Number of publications increased dramatically from 1976 (n = 1) to 2008 (n = 383). The top 5 journals publishing papers from Turkish authors were European Journal of Nuclear Medicine and Molecular Imaging (n = 328), Clinical Nuclear Medicine (n = 296), European Journal of Radiology (n = 289), European Radiology (n = 207) and Journal of Clinical Ultrasound (n = 186). All published papers received 18,419 citations and citation to paper ratio was 4.06. The rank of Turkey among other countries in terms of published papers improved during the last 25 years. Number of papers from Turkey published in radiology and medical imaging journals has increased at the start of the new millennium. Currently, Turkey is among the top 12 countries when the number of scientific papers published in radiology journals is taken into consideration.

    The purpose of this study was to assess the feasibility and profitability of a radiology department providing a six-point trauma ultrasound (US) examination for abdominal or pelvic free fluid as part of a trauma alert team. The study included 191 trauma alerts, which generated 156 US examinations. A radiologist and a departmental technologist carried beepers and responded to level I and II traumas. A departmental secretary or technologist recorded when the responding technologist exited and re-entered the department and if US was performed. If performed, the US examination evaluated the four abdominal and pelvic quadrants and the suprapubic and subxiphoid regions. For 64 patients, the responding technologist recorded the times of the trauma alert, emergency room arrival, US start and finish, and return to the radiology department. Median response, wait, scan duration, and return times were 2, 8, 5, and 7 minutes, respectively. Median costs for the technician, physician, archiving, transcription, and equipment were $8.17, $30.85, $0.97, $4.80, and $41.22, respectively. Reimbursement per examination averaged $110.60. Sensitivity analyses that varied the time spent (median vs mean), US non-use rate (10%-18%), and years of depreciation (5-7 years) yielded net results ranging from a $36.60 profit to a $6.12 loss per examination. A radiology department can profitably respond to trauma alerts and provide a six-point trauma US examination for free fluid.

    Purpose: To determine the economic efficiency of a whole-radiology in- and outpatient treatment with angiographic interventions performed as the main or sole therapy. Materials and Methods: The calculations represent the data of a university radiology department, including the following angiographic interventions (neuroradiology not considered): Vascular intervention (PTA, stent implantation) of kidneys and extremities, recanalization of hemodialysis access, chemoembolization, diagnostic arterioportal liver CT, port implantation, varicocele embolization, PTCD, percutaneous implantation of biliary stent. First, the different angiographic interventions are categorized with reference to the German DRG system 2005. Considering the example of a university hospital, the individual cost of each intervention is calculated and correlated with reimbursements by G-DRG2005 and so-called ''ambulant operation'' (EBM200plus). With these data, profits and losses are calculated for both in- and outpatient care. Results: Radiologic interventions of inpatients yield a profit in the majority of cases. With a base rate of 2900 Euro, the profits in our university hospital range between -872 Euro and +3411 Euro (mean: +1348 Euro). On the other hand, those angiographic interventions suitable for ''ambulant operation'' generate average profits of +372 Euro, if only direct costs are considered. The data of outpatient radiological interventions average between 381 Euro up to 1612 Euro lower than compared with profits obtained from in patient care. (orig.)

This report describes the calculations of radionuclide release and transport and of the resultant dose to the regional population, assuming a projected installed capacity of 220,000 MW in the year 2000, of which 144,000 MW would be nuclear. All elements of the fuel cycle were assumed to be in operation. The radiological dose was calculated as a one-year dose based on ingestion of 35 different food types as well as for nine non-food pathways, and was reported as dose to the total body and for six specific organs for each of four age groups (infant, child, teen, and adult). Results indicate that the average individual would receive an incremental dose of 7 x 10/sup -4/ millirems in the year 2000 from the operation of nuclear facilities within and adjacent to the region, five orders of magnitude smaller than the dose from naturally occurring radiation in the area. The major contributor to dose was found to be tritium, and the most significant pathways were immersion in air, inhalation of air, transpiration of tritium (absorption through the skin), and exposure radionuclide-containing soil. 60 references.

    integrated care will include an increased focus on patient education, monitoring, and follow-up. The most effective treatments will require an individualized, patient-centered approach. A workforce analysis shows that the number of trained physician specialists will be inadequate to provide this care. Well-trained sleep medicine practitioners at many levels will be needed to meet treatment goals, including some roles appropriate for sleep technologists. These factors provide challenges and opportunities for sleep technologists. In order to maintain viability as an allied health profession, the majority of sleep technologists will need to be better educated and demonstrate competency in more roles than overnight monitoring and record scoring. Models for this transition already exist, with several programs moving technologists from night work to days and from diagnosis to patient education, provision of treatment, and monitoring of adherence. The challenge for the professional association is to define new roles for sleep technologists and provide the education that the membership will require to flourish in those new roles.

    A study was conducted to evaluate the radiation transmission through lead equivalent aprons that are used in a radiology department. A large area beam (poor geometry) was employed for the transmission measurements, and backscatter was simulated by placing 7 '' of Lucite behind each apron. Separate ionization chambers were used to measure the incident and transmitted x-ray beams. Transmission measurements were made at 70 kVp and 100 kVp through aprons and protective shields from eight different vendors that were marked 0.25 mm and 0.5 mm lead equivalent. Transmissions through 0.254 mm and 0.508 mm of pure lead were also measured and were compared with the transmissions through the lead equivalent materials. In addition, the area densities of the aprons were measured to compare radiation transmission with respect to the weights of the aprons. At 70 kVp, the transmission through 0.254 mm of pure lead was 5.4% and the transmissions through the 0.25 mm lead equivalent materials were 4.3% to 10.2% with a mean value of 7.1% and a standard deviation (s.d.) of 1.4%. At 100 kVp, the values were 15% for 0.254 mm pure lead and 12.3% to 20.7% (mean 16.8%, s.d. 2.1%) for the 0.25 mm lead equivalent materials. The transmission through the 0.508 mm pure lead sample was 0.9% at 70 kVp, and the corresponding transmissions through the 0.5 mm lead equivalent materials were 0.6% to 1.6% (mean 1.0%, s.d. 0.2%). At 100 kVp, the transmission through the 0.508 mm lead sample was 5% and those through the 0.5 mm lead equivalent materials were 3.5% to 6.7% (mean 4.9%, s.d. 0.7%). The radiation transmissions at 70 kVp, through two 'lead-free' 0.5 mm lead equivalent aprons, were 1.7% and 1.9% and at 100 kVp the transmissions were 6.1% and 6.8%, respectively. This study indicates that there is a need to establish methods for acceptance testing of aprons and a need to establish acceptance limits for the x-ray transmission of aprons at specific kVp values. There is also a need for the

    Our aim in this study was to evaluate the effect of the radiologist, technologist, and other examination-related factors on the frequency of recommendations for additional imaging (RAI) during sonographic (US) interpretation. We retrospectively reviewed 719 US reports from a single academic medical center for the presence of RAI. All studies had been interpreted by one of three abdominal radiologists. Examinations were performed at an outpatient radiology facility with no onsite radiologist (n = 299) or at an inpatient emergency department or hospital-based outpatient setting that had an onsite radiologist (n = 420). Possible associations between the frequency of RAI and the presence of an onsite radiologist, location of the examination, body part or region imaged, patient age, technologist performing the exam, and radiologist reading the exam were evaluated. There were significant differences between each pair of radiologists in terms of overall frequency of RAI (p technologists (13.6%-40.0%, p = 0.03). However, other factors such as patient age, patient sex, US unit, patient location, and radiologist location were not associated with the frequency of RAI (p = 0.15-0.93). The individual radiologist and technologist influenced the frequency of RAI for US examinations, whereas other examination-related factors did not. The observed substantial variability in RAI between radiologists and technologists warrants further study, with consideration of strategies to optimize RAI within US reports. © 2015 Wiley Periodicals, Inc.

    About the situation of nuclear medicine technologists in Japan, survey was made in August, 1979, by sending questionnaire to 219 facilities, and 341 technologists responded, the recovery rate being 70%. About the situation in the United States, the data were taken from the similar survey results in 1975 and 1976. The results in Japan, as compared with those in the United States, are described as follows: years of experience, contents of work, participation in society meetings and others, and occupation prior to the employment as nuclear medicine technologists. The findings are interesting in such items as the sexes of the technologists, the participation in meetings, and the types of works. In Japan, the technologists are dominantly male, while in the United States, more than 80% are female. In Japan, 97% of the technologists participated in society meetings and others. (J.P.N.)

  10. International Stability. The Responsibility of the Scientist and Technologist

    International Nuclear Information System (INIS)

    1983-01-01

    Scientists and technologists ('technical experts') bear heavy responsibility for the explosive world situation where the further existence of civilization is threatened. Without their initiatives and their efforts the weapons of mass annihilation would not have been invented and developed. The essential features of nuclear warfare are explained. 25-40% of the world force of technical experts may be on war work now. Whatever justification for their work they see, they are tied to it, as quitting would mean loss of income, possibilities for professional career, status and prestige. On the other hand, many scientists, including Bohr, Joliot, Pauling, Einstein and Russell, have done invaluable work in informing, warning, educating and mobilizing the public against the danger of a nuclear war. In the present desperate situation the support of the largest possible number of technical experts for such activities ought to be enlisted. In this respect engineers and technologists could follow the example of medical doctors. Moreover, owing to their familiarity with criteria for stability in material systems engineers could make constructive proposals for the improvement of stability in international relations. (author)

  11. Radiological protection of the environment, including non-human species-views from the global nuclear industry

    Saint-Pierre, S.; RPWG

    2008-01-01

    This paper updates the WNA key messages on the RP of the environment. This paper shows that the chronology of views (2000-2008) leads to a recognition that the current RP system has provided adequate protection of people and of the environment. In early 2000s, doubts were raised on the adequacy of the RP system. Next (2002-2005), the international community forged the view that the current RP system has in practice provided appropriate standards of environmental protection, but also acknowledged that the system needs further development to fill a 'conceptual gap'. In 2005, the IAEA plan of activities on the RP of the environment formalized international developments and conditioned the future revision (if any) of current standards. During 2006-2008, ICRP issued new guidance on RP of non-human species which offers little on an assessment framework of practical use and on a compelling case for such assessments. This guidance, based on the new ICRP concept of Reference Animals and Plants, falls short in terms of environmental protection approach. A milestone study on the RP of non-human species is the SENES independent overview (2007) which 'confirmed that both people and nature have been adequately protected from radioactive releases from all kinds of nuclear sites, old and new'. This overview covers case studies for nuclear sites including some that had experienced major accidents. It derives that the earlier acknowledgement on the 'conceptual gap' appears no longer valid or at the very least, that the gap (if any) is extremely small. The RP of the environment is part of the on-going revision of the current IAEA Basic Safety Standards (BSS). We emphasize that the recently published BSS draft 1.0 in July 2008 covers (with adequacy) RP of the environment through general provisions (free of provisions to non-human species) on the assessment of environmental impact.

  12. Technologist assessment of abnormalities in mammography

    International Nuclear Information System (INIS)

    Cheesman, A.

    2006-01-01

    Clinical images must meet the needs of the radiologist in order to serve the patient well. Learning to fully appreciate and assess the range of potentially pathological concerns is an important part of the role of the mammographer within the breast imaging team: being sure of a complete study that serves the purpose for the radiologist goes beyond pure technical appreciation. It now requires some clinical knowledge in order to ensure the area of concern is appropriately imaged, clearly seen and readily characterized by the radiologist. The technologist's role in ensuring appropriate imaging to clarify the extent of potential disease becomes an integral part of the criteria for excellence. Application of our basic analytical skills to our patient history and clinical images should now be an expectation of the mammographic technologist. Assessing and demonstrating clearly an area of concern on our images is a long way from diagnosing disease. What is missed or obscured on our clinical images is not analyzed by the radiologist. Therefore it is essential that we recognize a possible concern and know how to demonstrate it clearly. To recognize what is potentially a concern, it helps to know a little about where and how pathology within the breast develops. There are three basic areas of concern when checking our images, clinical assessment, calcifications and masses. The mammographer within today's modern team oriented department must have the advanced positioning and clinical skills to ensure the area of concern is appropriately imaged, clearly seen and able to be characterized by the radiologist. To properly assess and demonstrate potential problems for our medical partner, the radiologist, we must understand well the three areas of clinical and pathological change that exposes early breast cancer.

    The Malaysian aviation industry has continued to march forward. With a turnover of RM23.7 billion in 2013, it is expected to grow higher especially after the Malaysian national aerospace blueprint was launched in 2015. The aviation related organizations currently have a workforce of approximately 13500. These organizations need to be managed by competent managers who have a strong background of technologist. Aviation technologist is one of the key components in the aviation maintenance industry as they are the future managers charged with the responsibility to ensure continuation of the organization's objectives and culture. The technologist role and manager's role are somehow different. The promotion of technologist to managerial roles is quite common but whether the technologist is able to take up managerial role effectively is yet to be fully understood. It is quite common that there was insufficient training for the technologist before being promoted to take up management roles. The purpose of this paper is to give an overview of the role of technologists and managers in professional services industries such as MRO and to understand that there is a need within the industry to re-look into the perspective of a proper training to prepare them to take up management roles effectively.

    The education of radiologic technology began in the regular institute of higher education in Korea in 1963. Up to now from then, our education to bring up the radiologic technologists has developed greatly in quality and quantity, and now departments of radio-technology are founded in the 16 junior colleges in March, 1995. This study was done to verify the necessity and propriety to reform the education system of radiologic technology which was run as two or three year system of college curriculum for 32 years since 1963, and to search for the method to reform in the future. We got the following results from this research. 1. In the survey, on the desirable education year for radiologic technologists, 63.9 % of professors of department of radio-technology and 63.0 % of radiologic technologists chose the 4 year system, 27.9 % of professors and 34.6 % of radiologic technologists chose the 4 year system added to graduate school. 2. In the survey, on the future development of radiologic equipment and technique, 67.2 % of professors of department of radiologic technology and 86.4 % of radiologic technologists have a view of 'revolutional development'. Also, on the future tasks or roles

    Full Text Available Christina C Mendat,1 Dave Mislan,2 Lisa Hession-Kunz2 1Human Factors MD, Charlotte, NC, 2Hologic Inc., Marlborough, MA, USA Abstract: A sample size of 280 certified mammography technologists were surveyed to understand what factors affect patient discomfort during breast imaging. Given mammography technologists’ level of patient involvement, they are uniquely positioned to observe factors that affect patient comfort. The findings suggest that according to technologists, multiple factors, including patient ethnicity, breast density, previous biopsy and lumpectomy experience, as well as psychological factors, impact breast discomfort during mammography. Additionally, with respect to imaging protocols, technologists attributed 80% of moderate-to-extreme discomfort to “length of compression time” (27% and “compression force” (53%. Technologists also attributed “pinching at chest wall” and “hard edges of breast platform” to “very high” discomfort significantly more times (P<0.05 than “coolness and edges of paddle”. These findings confirm some of what has been reported to date and challenge other findings. Given that recent decline in breast cancer mortality has been attributed to improvements in early detection and treatment, approaches to reduce discomfort should be considered in order to promote screening compliance. Although more research is needed, it is apparent that the patient experience of comfort and pain during mammography is an area warranting increased research and solutions.

    In 2015, the Society of Nuclear Medicine and Molecular Imaging Technologist Section (SNMMI-TS) launched a multiyear quality initiative to help prepare the technologist workforce for an evidence-based health-care delivery system that focuses on quality. To best implement the quality strategy, the SNMMI-TS first surveyed technologists to ascertain their perception of quality and current measurement of quality indicators. Methods: An internet survey was sent to 27,989 e-mail contacts. Questions related to demographic data, perceptions of quality, quality measurement, and opinions on the minimum level of education are discussed in this article. Results: A total of 4,007 (14.3%) responses were received. When asked to list 3 words or phrases that represent quality, there were a plethora of different responses. The top 3 responses were image quality, quality control, and technologist education or competency. Surveying patient satisfaction was the most common quality measure (80.9%), followed by evaluation of image quality (78.2%). Evaluation of image quality (90.3%) and equipment functionality (89.4%) were considered the most effective measures. Technologists' differentiation between quality, quality improvement, quality control, quality assurance, and quality assessment seemed ambiguous. Respondents were confident in their ability to assess and improve quality at their workplace (91.9%) and agreed their colleagues were committed to delivering quality work. Of note, 70.7% of respondents believed that quality is directly related to the technologist's level of education. Correspondingly, respondents felt there should be a minimum level of education (99.5%) and that certification or registry should be required (74.4%). Most respondents (59.6%) felt that a Bachelor's degree should be the minimum level of education, followed by an Associate's degree (40.4%). Conclusion: To best help nuclear medicine technologists provide quality care, the SNMMI-TS queried technologists to

    Radiologic science is a complex health profession, requiring the competent use of technology as well as the ability to function as part of a team, think critically, exercise independent judgment, solve problems creatively and communicate effectively. This article presents a review of literature in support of the relevance of collaborative learning to radiologic science education. In addition, strategies for effective design, facilitation and authentic assessment of activities are provided for educators wishing to incorporate collaborative techniques into their program curriculum. The connection between the benefits of collaborative learning and necessary workplace skills, particularly in the areas of critical thinking, creative problem solving and communication skills, suggests that collaborative learning techniques may be particularly useful in the education of future radiologic technologists. This article summarizes research identifying the benefits of collaborative learning for adult education and identifying the link between these benefits and the necessary characteristics of medical imaging technologists.

    The purpose of our study was to create a real-time electronic dashboard in the pediatric radiology reading room providing a visual display of updated information regarding scheduled and in-progress radiology examinations that could help radiologists to improve clinical workflow and efficiency. To accomplish this, a script was set up to automatically send real-time HL7 messages from the radiology information system (Epic Systems, Verona, WI) to an Iguana Interface engine, with relevant data regarding examinations stored in an SQL Server database for visual display on the dashboard. Implementation of an electronic dashboard in the reading room of a pediatric radiology academic practice has led to several improvements in clinical workflow, including decreasing the time interval for radiologist protocol entry for computed tomography or magnetic resonance imaging examinations as well as fewer telephone calls related to unprotocoled examinations. Other advantages include enhanced ability of radiologists to anticipate and attend to examinations requiring radiologist monitoring or scanning, as well as to work with technologists and operations managers to optimize scheduling in radiology resources. We foresee increased utilization of electronic dashboard technology in the future as a method to improve radiology workflow and quality of patient care. Copyright © 2017 Elsevier Inc.

    This paper reports on the importance of postoperative radiology. Most surgical procedures on the alimentary tract are successful, but postoperative complications remain a common occurrence. The radiologist must be familiar with a large variety of possible surgical complications, because it is this specialty that is most commonly called on to render a definitive diagnosis. The decision for reoperation, for instance, is usually based on results from radiologic imaging techniques. These now include ultrasonography, CT scanning, needle biopsy, and interventional techniques in addition to contrast studies and nuclear medicine investigation

    In this study, we assessed the community and educational needs for sleep technologists by surveying program directors of nationally accredited polysomnography, electroneurodiagnostic technology, and respiratory care educational programs. Currently, little is known about our educational capacity and the need for advanced degrees for sleep medicine technical support. A questionnaire was developed about current and future community and educational needs for sleep technologists. The questionnaire was sent to directors of CAAHEP-accredited polysomnography and electroneurodiagnostic technology programs (associate degree and certificate programs), and directors of CoARC-accredited respiratory therapy associate degree and bachelor degree programs (n = 358). Qualitative and quantitative data were collected via an internet survey tool. Data analysis was conducted with the IBM SPSS statistical package and included calculating means and standard deviations of the frequency of responses. Qualitative data was analyzed and classified based on emerging themes. One hundred seven of 408 program directors completed the survey. Seventy-four percent agreed that demand for qualified sleep technologists will increase, yet 50% of those surveyed believe there are not enough educational programs to meet the demand. Seventy-eight percent of those surveyed agreed that the educational requirements for sleep technologists will soon increase; 79% of those surveyed believe sleep centers have a need for technologists with advanced training or specialization. Our study shows educators of associate and certificate degree programs believe there is a need for a bachelor's degree in sleep science and technology.

    2005-01-01

    Recently, so many medical institutions established and the increasing use of the high technological medical imaging equipment, it makes radiological technology become the main instrument for the medical diagnostic and radiation therapy. However, the medical radiological technologies play the important role to operate all the related radiological machines. If they do not use the machines adequately, it will increase the patients' radiation absorbed dose. Then, the whole society health may be influenced. Therefore, constructing the professional competence of the medical radiological technologists is an important course. The purpose of this research are: (1) to construct the index of professional competence with radiological technology students, (2) to discuss the professional competence for the graduates from the department of radiological technology to be the reference for the Ministry of Examination for the license test of radiological technologists, (3) to provide the direction of the radiological technology department development.

    2002-12-01

    Full Text Available Simulation modelling was in the mainstream of CAL development in the 1980s when the late David Squires introduced this author to the Dynamic Modelling System. Since those early days, it seems that simulation modelling has drifted into a learning technology backwater to become a member of Laurillard's underutilized, 'adaptive and productive' media. Referring to her Conversational Framework, Laurillard constructs a pedagogic case for modelling as a productive student activity but provides few references to current practice and available resources. This paper seeks to complement her account by highlighting the pioneering initiatives of the Computers in the Curriculum Project and more recent developments in systems modelling within geographic and business education. The latter include improvements to system dynamics modelling programs such as STELLA®, the publication of introductory textbooks, and the emergence of online resources. The paper indicates several ways in which modelling activities may be approached and identifies some educational development roles for learning technologists. The paper concludes by advocating simulation modelling as an exemplary use of learning technologies - one that realizes their creative-transformative potential.

    The demand for nuclear medicine technologists (NMTs) in Kuwait has increased, especially with the introduction of multimodality imaging systems. In order to increase the number of NMTs in the workforce and retain the existing NMTs, there should be a better way to motivate them. To find out how satisfied NMTs are and the factors that motivate them. An interview was conducted with 40 randomly selected NMTs to explore deep-seated emotions and attitudes that were related to motivation. Questions about the recognition NMTs receive from the general public, whether they are acknowledged as significant contributors to health services, ways to improve the standing of NMTs in society, and the clarity of the job description were included. A questionnaire survey was then conducted with 100 randomly selected NMTs. The questions were designed to elicit wider perspective of the information obtained from the interviews. The results show a need for attention in the Ministry of Health to NMTs for recognition, motivation, and improvement. Giving the NMTs their own identity and opportunities to be part of decision-making in the health team would influence more students to join nuclear medicine departments and give more self-confidence to the existing NMTs.

    Full text: Therapeutic doses of I-131 for treatment of thyroid cancer are administered orally in liquid or capsule form. During the last few years, a total number of patients loaded in our isolation ward increased from 4 to 10 patients per week. When considering radiation safety precautions for attending technologists, it is preferable to use the dose in capsules. The purpose of this study is to compare radiation exposure to nuclear medicine technologists from administering I-131 therapy dosages in capsules and in liquid form in a closed system. Materials and Methods: Three year radiation exposure to technologists during I-131 administration was analyzed. From January 2004 to June 2005 dose administration was in liquid form (n=263) and from July 2005 to February 2007 in capsules (n=541). Radiation dose assessment was performed with an electronic personal dosimeter (PDM 112). The dose rate in μSv and time spent per patient were recorded. Results: Dose received per patient when I-131 was given in a liquid was 3.50 ± 1.67 μSv and 1.17 ± 0.66 μSv when given in capsules. Compared with the use of a liquid, capsules significantly reduced radiation dose to technologists by 66% (P < 0.001). These doses received depended not only on the administered activity but also on the time, distance and shielding. Time spent per patient, including a brief visit before the time of dosing to explain the procedure and answer questions was reduced slightly from 4.4 ± 2.2 to 3.7 ± 1.8 minutes (P < 0.01). These correspond to a reduction in a yearly dose to 1 technologist by 40%, from 0.63 mSv to 0.38 mSv from dosing to 175 and 325 patients respectively. Conclusions: The measured doses clearly showed that handling of I-131 therapy dosages either in a liquid form or capsules are not the major contributors to the technologist's radiation exposure in routine clinical practice. However, one has to be cautious and follow good work practice to avoid risk of radiation exposure and radioiodine

    Current medical care is subdivided according to medical advances, and sophistication and new techniques are necessary. In this setting, doctors and nurses have been explaining to and consulting patients about their medical examinations; however, in recent years, medical technologists have performed these duties at the start of the team's medical care. Therefore, we think it is possible for patients to receive clear and convincing explanations. Most patients cannot understand their examination data, which are written using numbers and charts, etc. Recently, the Nagano Medical Technologist Society has been developing technologists who could explain examination results to patients. This development training included hospitality and communication. The certificate of completion will be issued in March when the program starts.

    This study was conducted to survey of radiation safety control and to measure occupational radiation exposure dose of staff in interventional radiology in Korea. Interventioanl radiology requires the operator and assisting personnel to remain close to the patient, and thus close to primary beams of radiation. Therefore exposure doses of these personnel are significant from a radiological protection point of view. We surveyed the status of radiation safety on interventional radiology of 72 hospitals. The result were that 119 radiation equipments are using in interventional radiology and 744 staffs are composed of 307 radiologists, 116 residents of radiology, 5 general physicians, 171 radiologic technologists and 145 nurses. 81.4% and 20.2 % of operating physicians are using neck collar protector and goggle respectively. The average radiation dose was measured 0.46±0.15 mSv/10 hours fluoroscopy inside examination room in radiation protection facilities. Occupational radiation exposure data on the staff were assessed in interventional radiology procedures from 8 interventional radiology equipments of 6 university hospitals. The dose measurements were made by placing a thermoluminesent dosimeter(TLD) on various body surface of operation and assistant staff during actual interventional radiology. The measured points were the corner of the eyes, neck(on the thyroid) , wrists, chest(outside and inside of the protector), and back. Average radiation equivalent dose of the corner of left eye and left wrist of operating physicians were 1.19 mSv(0.11∼4.13 mSv)/100 minutes fluoroscopy and 4.32 mSv(0.16∼11.0 mSv)/100 minutes fluoroscopy respectively. Average exposure dose may vary depending on the type of procedure, personal skills and the quality of equipment. These results will be contributed to prepare the guide line in interventional radiology in Korea

    Nuclear medicine technologists may not have had opportunity to read periodic journals on a regular basis and may feel intimidated by the content, style and jargon used in many journal articles. By becoming familiar with the style of articles and having some grasp of the basic concepts underlying statistical description of data errors and their relation to hypothesis testing, the technologist can begin to appreciate the content in journals. In particular they should appreciate that journal articles are open to debate and do not necessarily represent 'truth' (Au)

    Natural radionuclides are part of the human environment and of the raw materials used. Technical processes may cause their accumulation in residues, and the result will be so-called NORM materials (Naturally occurring radioactive material). The amended Radiation Protection Ordinance (StrlSchV 2001) specifies how the public should be protected, but there are also residues dating back before the issuing of the StrlSchV 2001, the so-called NORM residues. The project intended to assess the risks resulting from these residues. It comprises four parts. Part 1 was for clarification of the radiological relevance of NORM residues and for the development of concepts to detect them. The criterion for their radiological relevance was their activity per mass unit and the material volume accumulated through the centuries. The former was calculated from a wide bibliographic search in the relevant literature on radiation protection, while the mass volume was obtained by a detailed historical search of the consumption of materials that may leave NORM residues. These are, in particular, residues from coal and ore mining and processing. To identify concrete sites, relevant data sources were identified, and a concept for identification of concrete NORM residues was developed on this basis. (orig.) [de

    Radiation exposures incurred by nuclear medicine technologists during diagnostic imaging and gamma camera quality control (QC) were measured on a procedural basis over a three-month period using a portable, low-range, self-reading ion chamber. A total of more than 400 measurements were made for 15 selected procedures. From these, mean procedural exposures and standard deviations were calculated. The results show that daily flood phantom QC, at 0.58 mR, and gated cardiac studies, at 0.45 mR, were the two greatest sources of exposure. Other procedures resulted in exposures varying roughly from 0.10 to 0.20 mR. Difficult patients were responsible for a doubling of technologist exposure for many procedures. Standard deviations were large for all procedures, averaging 65% of the mean values. Comparison of technologist exposure inferred from the procedural measurements with the time coincident collective dose equivalent recorded by the TLD service of the Radiation Protection Bureau indicates that approximately half of the collective technologist exposure arose from patient handling and flood QC

    Pediatric radiology is an important subsection of diagnostic radiology involving specific difficulties, but unfortunately is quite too often neglected as a subject of further education and training. The book therefore is not intended for specialists in the field, but for radiologists wishing to plunge deeper into the matter of pediatric radiology and to acquire a sound, basic knowledge and information about well-proven modalities, the resulting diagnostic images, and interpretation of results. The book is a compact guide and a helpful source of reference and information required for every-day work, or in special cases. With patients who are babies or children, the challenges are different. The book offers all the information needed, including important experience from pediatric hospital units that may be helpful in diagnostic evaluation, information about specific dissimilarities in anatomy and physiology which affect the imaging results, hints for radiology planning and performance, as well as information about the various techniques and their indication and achievements. The book presents a wide spectrum of informative and annotated images. (orig./CB) [de

    Individual and collective radiation doses received by Canadian radiation technologists (RTs) working in diagnostic radiology, nuclear medicine and radiotherapy are summarized for the period 1978 to 1988. The data were obtained directly from the National Dose Registry, Department of National Health and Welfare. Over the 11-year study period the mean annual dose equivalent fluctuated around 0.2, 1.8 and 1.1 mSv for RTs working in diagnostic radiology, nuclear medicine and radiotherapy respectively. Over the same period the occupational collective dose equivalent decreased in diagnostic radiology by 44% and radiotherapy by 35%, and increased in nuclear medicine by 45%. Approximately 10 000 RTs are monitored each year, with an estimated total occupational collective dose equivalent of about 3.6 person-sievert. Analysis of dose distribution data showed that only 1.3% of all monitored RTs received an annual whole-body dose equivalent greater than the current legal limit for members of the public (5 mSv). Approximately half of the RTs working in nuclear medicine and radiotherapy received an annual dose equivalent in excess of 0.5 mSv; only 7.3% of their diagnostic radiology counterparts exceeded this level. Demographic data showed a high preponderance of young women in all three RT classifications, and an analysis of the radiation risks to this occupational group revealed increases of up to 12% above the risk associated with a 'standard' adult working population exposed to the same collective dose equivalent.

    Recently, there have been marked advances in the technological strategies employed in medical examinations. The educational concept to nurture highly capable medical technologists is considered to be a priority issue by not only educators but also employers, even though the medical educational levels have markedly improved in every college and university. It is commonly acknowledged that the results of any examination in the clinical laboratory should be accurate and fed back to medical doctors as soon as possible. The business outline of medical technologists in our hospital is becoming more extensive because we act as a core hospital in the area, and so knowledge regarding many kinds of chemical and transfusion examinations is required in operations performed around the clock. Furthermore, medical doctors, clerical workers, nurses, and volunteers comprise a team of sophisticated workers in our hospital. To accomplish our daily work, character traits such as accuracy, honesty, perseverance, and ability to follow instruction manuals, are the most fundamental and valuable. To nurture a highly career-oriented medical technologist, we propose that the following should be focused on: self-responsibility, reduction of malpractices, economic profitability, brainstorming, education of subsequent generations, and the spirit of cooperativeness and reconciliation. Additionally, it is another basic requirement of competent medical technologists to learn to adapt to laboratory-based changes in their work throughout their career. In conclusion, how to adapt to any social demand and learn strategies in any era should be taught in college or university as well as after graduation because each hospital and institute has a different philosophy and requirements of newcomers. It is important for medical technologists and doctors to develop flexible ways of thinking, although we sometimes might accede to traditional ways.

    A fully automated and comprehensive Radiology Department system was implemented in the Fall of 1980, which highly integrates the multiple functions of a large Radiology Department in a major medical center. The major components include patient registration, film tracking, management statistics, patient flow control, radiologist reporting, pathology coding and billing. The highly integrated design allows sharing of critical files to reduce redundancy and errors in communication and allows rapid dissemination of information throughout the department. As one node of an integrated distributed hospital system, information from central hospital functions such as patient identification are incorporated into the system and reports and other information are available to other hospital systems. The system is implemented on a Data General Eclipse S/250 using the MIIS operating system. The management of a radiology department has become sufficiently complex that the application of computer techniques to the smooth operation of the department has become almost a necessity. This system provides statistics on room utilization, technologist productivity, and radiologist activity. Room utilization graphs are a valuable aid for staffing and scheduling of technologists, as well as analyzing appropriateness of radiologic equipment in a department. Daily reports summarize by radiology section exams not dictated. File room reports indicate which film borrowers are delinquent in returning films for 24 hours, 48 hours and one week. Letters to the offenders are automatically generated on the high speed line printer. Although all radiology departments have similar needs, customization is likely to be required to meet specific priorities and needs at any individual department. It is important in choosing a system vendor that such flexibility be available. If appropriately designed, a system will provide considerable improvements in efficiency and effectiveness.

    An aerial radiological survey was conducted of major sections of the Tonopah Test Range (TTR) in central Nevada from August through October 1993. The survey consisted of aerial measurements of both natural and man-made gamma radiation emanating from the terrestrial surface. The initial purpose of the survey was to locate depleted uranium (detecting 238 U) from projectiles which had impacted on the TTR. The examination of areas near Cactus Springs Ranch (located near the western boundary of the TTR) and an animal burial area near the Double Track site were secondary objectives. When more widespread than expected 241 Am contamination was found around the Clean Slates sites, the survey was expanded to cover the area surrounding the Clean Slates and also the Double Track site. Results are reported as radiation isopleths superimposed on aerial photographs of the area

    Substantial effort has been placed into enhancing federal capabilities for responding to a Chemical, Biological, Radiological, or Nuclear (CBRN) terrorist attack. However, little emphasis has been placed on including the local-level medical responders in these efforts. In effecting response to a radiological incident, potentially useful resources to access are health care professionals with training in matters of ionizing radiation, namely: nuclear medicine physicians, radiologists, radiation oncologists, medical physicists, and technologists. In this report, we focus on Nuclear Medicine expertise in Canada, and place this expertise into the context of assisting with a radiological terrorist incident. Nuclear Medicine expertise, along with its supporting infrastructure has already been deployed in proportion to the distribution of the civilian population. Given the expectations that the civilian population places in these health care professionals, their immediate access to specialized equipment, and the delay between a radiological terrorist incident and the arrival of federal expert capabilities, it is likely that these health care professionals will play important roles in emergency response. These roles will likely be: identifying the nature of the incident, triage, decontamination, coordinating with First Responders, and communicating with the media. Acknowledging the potential value of these professionals in responding to a radiological terrorist incident, steps should be taken to enlist their support and integrate them into a coherent national strategy.

    Full Text Available In 1972, Edsger Dijkstra claimed that computers had only introduced the new problem of learning to use them effectively. This is especially true in 2015 with regard to powerful new educational technologies. This article describes the challenges that 21st century educational technologists are, and will be, addressing as they undertake the effective integration of new technologies into K-12 educational systems and learning environments. The expanding Internet, ever more powerful mobile devices, and other innovations make the task of designing effective formal and informal learning challenging, especially in light of the high rate of change in these new technologies. While these technologies introduce many benefits, they are also causing serious threats to system security and personal privacy. Furthermore, as these technologies continue to evolve, ethical issues such as equal access to resources become imperative. Educational technologists must expand their forward-thinking leadership and planning competencies so as to ensure effective use of new technologies.

    Full Text Available The paper describes the results of research aimed at assessing the current conditions related to clinical laboratory technologist professional development. A descriptive cross study covering the period between November 2013 and January 2014 is presented. Several techniques for identifying and hierarchically arranging professional developmental related problems were used to study a sample at the Faculty of Health Technology of the Medical University “Carlos Juan Finlay”. The study involved heads of teaching departments and methodologists of health care technology specialties; moreover a survey and a content test were given graduate clinical laboratory technicians. The authors reached at the conclusion that clinical laboratory technologist professional development is limited and usually underestimate the necessities and interests of these graduates. Likewise, a lack of systematization and integration of the biomedical basic sciences contents and the laboratory diagnosis is noticeable.

    Many studies have demonstrated that the exposure of nuclear medicine technologists arises primarily from radioactive patients rather than from preparation of radiopharmaceuticals. However, in order to devise strategies to reduce staff exposure, it is necessary to identify the specific tasks within each procedure that result in the highest radiation doses. An ESM Eberline FH41B-10 radiation dosemeter, which records the ambient dose equivalent rate, was used to monitor the radiation exposure of a technologist and to record the dose rate in μSv per hour every 32 s throughout a working day. The technologist recorded the procedures that were being performed so that the procedures that resulted in higher doses could be identified clearly. The measured doses clearly showed that the major contributions to the technologist's dose were the following: (1) transferring incapacitated patients from the imaging table to a hospital trolley; (2) difficult injections without syringe shields; and (3) setting up patients for gated myocardial scans. The average dose to the technologist from transferring patients after a bone scan was 0.54 μSv, 40% of the total dose of 1.3 μSv for the complete bone scan procedure. The average dose received injecting 900 MBq of 99 Tc m -HDP using a tungsten syringe shield was 0.57 μSv, but the highest dose was 1.6 μSv, in a patient in whom the injection was difficult. A 0.5 mm lead apron was found to reduce the dose when setting up a patient for a gated stress 99 Tc m -sestamibi myocardial scan by approximately a factor of 2. The average dose per patient for this task was reduced from 1.1 to 0.6 μSv. It is recommended that staff waiting for assistance with patient transfers stand away from the patient, that tungsten syringe shields be used for all radiopharmaceutical injections and that a 0.5 mm lead apron be worn when attending patients containing high activities of 99 Tc m radiopharmaceuticals, such as those having myocardial imaging.

    The modern radiology department is built around the flow of information. Ordering providers request imaging studies to be performed, technologists complete the work required to perform the imaging studies, and radiologists interpret and report on the imaging findings. As each of these steps is performed, data flow between multiple information systems, most notably the radiology information system (RIS), the picture archiving and communication system (PACS) and the voice dictation system. Even though data flow relatively seamlessly, the majority of our systems and processes are inefficient. The purpose of this article is to describe the radiology value stream and describe how radiology informaticists in one department have worked to improve the efficiency of the value stream at each step. Through these examples, we identify and describe several themes that we believe have been crucial to our success. (orig.)

    processes occurring at the geosphere-biosphere interface and in the surface environment. One of the primary outputs of the NAnet project has been the compilation of reviews of more than 70 individual analogue studies with relevance for the near-field, far field or biosphere. Each analogue study review was documented using a standard review template that includes sections concerned with performance assessment relevance and applications, limitations of the analogue, a summary of any particular quantitative information derived from the study, an assessment of the uncertainties associated with the qualitative and quantitative information, an indication of the time-scales covered by the analogue and reference to any applications in communication and links to the primary literature. A simple referencing system was developed that enables safety assessors and communication specialists rapidly to find all those analogues that relate to their specific issues and interests. It is based on a simple matrix that has on one axis the range of materials and on the other axis the range of processes that can occur in the repository system. Intersections of the axes identify unique material-process combinations and analogue studies can be listed at the appropriate intersections. Two generic analogue matrices have been developed, one for the near-field and one for the far-field. Combining analogue studies with field and laboratory investigations provides a powerful means of investigating the natural processes which will occur in the repository environment because the disadvantages of one method are balanced by the advantages of the other. In order to illustrate how analogues can contribute to build technologists confidence, examples for the three different roles of analogues are given. Analogue studies contribute to technologists confidence by increasing the understanding of processes that control the evolution of the repository system over time. Qualitative information from analogues is of

    In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications.

    In this paper, we give a short introduction to machine learning and survey its applications in radiology. We focused on six categories of applications in radiology: medical image segmentation, registration, computer aided detection and diagnosis, brain function or activity analysis and neurological disease diagnosis from fMR images, content-based image retrieval systems for CT or MRI images, and text analysis of radiology reports using natural language processing (NLP) and natural language understanding (NLU). This survey shows that machine learning plays a key role in many radiology applications. Machine learning identifies complex patterns automatically and helps radiologists make intelligent decisions on radiology data such as conventional radiographs, CT, MRI, and PET images and radiology reports.

    Computed tomography has made possible the excellent and basic work having to do with the characteristics of the trachea, its caliber, shape, and length in children. Another group of articles has to do with interventional pediatric radiology. This year there were a number of articles of which only a sample is included, dealing with therapeutic procedures involving drainage of abscesses, angioplasty, nephrostomy, therapeutic embolization, and the removal of esophageal foreign bodies. Obviously, there is no reason to think that techniques developed for the adult may not be applicable to the infant or child; also, there is no reason to believe that processes peculiar to the child should not be amenable to intervention, for instance, use of embolization of hepatic hemangioma and transluminal balloon valvuloplasty for pulmonary valvular stenosis. Among the reports and reviews, the author would add that sonography remains a basic imaging technique in pediatric radiology and each year its application broadens. For example, there is an excellent article having to do with sonography of the neonatal and infant hip and evaluation of the inferior vena cava and the gallbladder. Nuclear medicine continues to play a significant role in diagnosis, which is featured in two articles concerned with problems of the hip

    2011-03-01

    Conventional diagnostic nuclear medicine applications have been continuously increasing in most nuclear medicine departments in Turkey, but to our knowledge no one has studied the doses to technologists who perform nuclear medicine procedures. Most nuclear medicine laboratories do not have separate control rooms for technologists, who are quite close to the patient during data acquisition. Technologists must therefore stay behind lead shields while performing their task if they are to reduce the radiation dose received. The aim of this study was to determine external radiation doses to technologists during nuclear medicine procedures with and without a lead shield. Another aim was to investigate the occupational annual external radiation doses to Turkish technologists. This study used a Geiger-Müller detector to measure dose rates to technologists at various distances from patients (0.25, 0.50, 1, and 2 m and behind a lead shield) and determined the average time spent by technologists at these distances. Deep-dose equivalents to technologists were obtained. The following conventional nuclear medicine procedures were considered: thyroid scintigraphy performed using (99m)Tc pertechnetate, whole-body bone scanning performed using (99m)Tc-methylene diphosphonate, myocardial perfusion scanning performed using (99m)Tc-methoxyisobutyl isonitrile, and (201)Tl (thallous chloride) and renal scanning performed using (99m)Tc-dimercaptosuccinic acid. The measured deep-dose equivalent to technologists per procedure was within the range of 0.13 ± 0.05 to 0.43 ± 0.17 μSv using a lead shield and 0.21 ± 0.07 to 1.01 ± 0.46 μSv without a lead shield. Also, the annual individual dose to a technologist performing only a particular scintigraphic procedure throughout a year was estimated. For a total of 95 clinical cases (71 patients), effective external radiation doses to technologists were found to be within the permissible levels. This study showed that a 2-mm lead shield

    To evaluate the current status of interventional radiology in Canada. A questionnaire was sent to 28 Canadian interventional radiologists (defined as a physician who performs any type of interventional procedure, including biopsies, but excluding interventional neuroradiology) practising in both tertiary and community hospitals in the major centres in all provinces except Prince Edward Island. Twenty-two (79%) of 28 surveys were completed and returned, providing data about 86 interventional radiologists (IRs). IRs were performing almost all of the following procedures at their institutions: inferior vena cava filter placement, venous angioplasty, dialysis fistula angioplasty, diagnostic and therapeutic pulmonary and bronchial artery procedures, diagnostic and therapeutic procedures of the lower extremity and renal arteries, percutaneous abscess and biliary drainage procedures, percutaneous nephrostomy, and fibroid embolization. A second group of procedures, performed by both IRs and non-radiologists in most institutions, included: all types of central venous catheter placements, pleural drainage, and gastrostomy tube placement. Procedures not being performed by anyone in a number of institutions included: dialysis graft thrombolysis, varicocele embolization, transjugular intrahepatic portosystemic shunts, palliative stenting of the gastrointestinal tract, fallopian tube recannalization, and liver and prostate tumour treatments. The factors most often limiting the respondents' ability to provide a comprehensive interventional service were the interventional radiology inventory budget and the availability of interventional radiology rooms; 50% of respondents indicated the number of available nurses, technologists and IRs was also an important limiting factor. IRs in Canada still play a major role in many of the most commonly performed procedures. However, limited availability of resources and personnel in many institutions may be hampering the ability of IRs to

    Interventional radiological procedures are on the increase by virtue of the fact that these procedures replace highly invasive surgical and other procedures. Radiation dose to patients and hospital workers are of significance since these procedures tend to impart large dose to them. Moreover, long term risk from radiation absorbed by patients is of concern since the life expectancy of major fraction of patients is long after undergoing the procedure. This study intends to measure radiation dose imparted to patients as well as personnel- radiologists, technologists, nurses, etc. and estimate the risk factor involved

    2001-01-01

    The first international conference specifically focused on the radiological protection of patients will be held in Torremolinos (Malaga), Spain, next week, from 26 to 30 March 2001. The conference, formally titled, 'International Conference on the Radiological Protection of Patients in Diagnostic and Interventional Radiology, Nuclear Medicine and Radiotherapy', is being organized by the IAEA, hosted by the Government of Spain and co-sponsored by the European Commission, the Pan American Health Organization and the World Health Organization. Medical applications of ionizing radiation are accepted world-wide as essential tools for keeping or restoring human health. However, they also represent by far the largest man-made source of radiation exposure. The United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR) estimates that diagnostic medical applications of radiation account for about 95% of the exposure to radiation from man-made sources of radiation and about 12% of total exposure, which includes the exposures received from natural sources. More than 900 participants from 80 countries are expected to attend the conference. They cover a broad spectrum of expertise, including radiologists, nuclear medicine specialists, radiation oncologists, medical physicists, technologists/radiographers, radiological protection officers, equipment manufacturers, experts who develop standards for radiological equipment, hospital administrators and public health officials and representatives of professional societies. In addition, a number of patients who have undergone radiation treatment will represent patients' interests and a patient will chair one of the round table debates. The conclusions of the Conference will be incorporated into the IAEA's programme of work in the field of radiation safety and will be reported to the IAEA General Conference at its next meeting in September 2001

    2004-01-01

    The physicians, technicians, nurses, and others involved in radiation areas constitute the largest group of workers occupationally exposed to man-made sources of radiation. Personnel radiation exposure must be monitored for safety and regulatory considerations, this assessment may need to be made over a period of one month or several months. The purpose of this study was to carry out an exploratory survey of occupational exposures associated with diagnostic radiology. The personnel dosimeters used in this study were thermoluminescent dosimeters (TLDs). The reported number of monitored workers was 110 of different departments of radiology of the Mexican Republic without education in radiation safety, included general fluoscopic/radiographic imaging, computed tomography and mammography procedures. Physicians and X-ray technologist in diagnostic radiology receive an average annual effective dose of 2.9 mSv with range from 0.18 to 5.64 mSv. The average level of occupational exposures is generally similar to the global average level of natural radiation exposure. The annual global per capita effective dose due to natural radiation sources is 2.4 mSv (UNSCEAR 2000 Report). There is not significant difference between average occupational exposures and natural radiation exposure for p < 0.05

    2017-06-01

    Errors by nuclear medicine technologists during the preparation of radiopharmaceuticals or at other times can cause patient harm and may reflect the impact of interruptions, busy work environments and deficient systems or processes. We aimed to: (a) characterise the rate and nature of interruptions technologists experience and (b) identify strategies that support safety. We performed 100 hours of observation of 11 technologists at a major public hospital and measured the proportions of time spent in eight categories of work tasks, location of task, interruption rate and type and multitasking (tasks conducted in parallel). We catalogued specific safety-oriented strategies used by technologists. Technologists completed 5227 tasks and experienced 569 interruptions (mean, 4.5 times per hour; 95% CI 4.1 to 4.9). The highest interruption rate occurred when technologists were in transit between rooms (10.3 per hour (95% CI 8.3 to 12.5)). Interruptions during radiopharmaceutical preparation occurred a mean of 4.4 times per hour (95% CI 3.3 to 5.6). Most (n=426) tasks were interrupted once only and all tasks were resumed after interruption. Multitasking occurred 16.6% of the time. At least some interruptions were initiated by other technologists to convey important information and/or to render assistance. Technologists employed a variety of verbal and non-verbal strategies in all work areas (notably in the hot-lab) to minimise the impact of interruptions and optimise the safe conduct of procedures. Although most were due to individual choices, some strategies reflected overt or subliminal departmental policy. Some interruptions appear beneficial. Technologists' self-initiated strategies to support safe work practices appear to be an important element in supporting a resilient work environment in nuclear medicine.

    Protocol development between radiology and pediatric emergency medicine requires a multidisciplinary approach to manage straightforward as well as complex and time-sensitive needs for emergency department patients. Imaging evaluation requires coordination of radiologic technologists, radiologists, transporters, nurses and coordinators, among others, and might require accelerated routines or occur at sub-optimal times. Standardized protocol development enables providers to design a best practice in all of these situations and should be predicated on evidence, mission, and service expectations. As in any new process, constructive feedback channels are imperative for evaluation and modification. (orig.)

    Full Text Available This study highlights the importance of biosecurity in the work of technicians and technologists in Radiology. As a means of motivation research, it was observed that despite the investment of the hospitals and clinics for the improvement of radiological techniques, little has been done to prevent the spread of diseases among the professionals in radiology. To do so, held the same direction by quantitatively and qualitatively, using the analytical method and a questionnaire as the technique of analysis, with the sample of 29 professionals located in public hospitals, the School LS and in private practice. The results demonstrated that there is knowledge of biosafety among radiology professionals, but there is no understanding of the relevance of the subject by some a good portion of them.

In India, the Atomic Energy Regulatory Board (AERB) constituted by Government of India under the Atomic Energy Act (1962) and Radiation Protection Rules (1971) to enforce legislation concerning radiation, is the competent authority which stipulates the qualification requirements of technologists. 3 tabs

    1966-04-01

    This is the third in a series of reports prepared by the-National Advisory Committee on Radiation for the Surgeon General of the Public Health Service. The first two were directed to the broad responsibilities of the Service in the field of radiation control and to problems concerned with the protection of the public against undue radiation exposure from contamination of the environment with radioactive materials. In this report the Committee traces the remarkable growth that has taken place in the uses of ionizing radiation in the health professions, in industry, and in other walks of life. It also notes a number of emerging problems which not only are of importance from the point of view of radiation protection, but also, if not alleviated, threaten the quality of medical care in the United States and the translation of the advances of atomic research into needed benefits for the people. These problems include (a) serious weaknesses in academic departments of radiology which have restricted efforts to provide adequate instruction of medical and post-doctoral students in the clinical applications of ionizing radiation, including radiation protection; and (b) an increasingly severe shortage of manpower in all branches of the radiological sciences. The magnitude and complexity of these problems are sufficiently great that a concerted effort is needed by the Public Health Service to correct them. The alleviation of the problems just cited is but a part of a more comprehensive series of responsibilities faced by the Service in the radiological sciences. The Service must play an important role in the prevention of undue exposure of the population from medical, occupational, and environmental sources of ionizing radiation; at the same time, it must actively support the development and application of radiological methods in the diagnosis and treatment of diseases. In order that the Service may effectively meet its enlarging responsibilities in the radiological sciences

    Powers, Kevin J

    2005-01-01

    A total of 326 programs are represented in the data collected. Based on the average number of full- and part-time faculty members reported per program, this survey represents more than 1500 faculty positions. Based on the forecast of retirement and career change for all faculty members, there will be a turnover of 700 to 800 positions over the next 5 to 10 years. Part-time/adjunct faculty vacancies are expected to create the greatest number of opportunities for technologists to make the transition to education, with approximately one third of current part-time/adjunct educators planning on leaving radiologic sciences education within 5 years. To encourage retention of part-time/adjunct educators, annual evaluations should be modified to recognize the important educational role these instructors play. There is a need to create enthusiasm and interest in education as a career pathway for radiologic technologists. Resources are needed that help radiologic technologists make the transition to teaching. Finally, the retention of educators must be emphasized. Program applicant trends indicate radiologic technology students are older, have prior postsecondary education experience or are making a career change. This data emphasizes the need for educators, both full time and part time, to understand the characteristics and needs of the adult learner. Adult learners bring a wealth of education, experience and life skills that create both opportunities and challenges in the classroom and clinical setting. All categories of respondents indicated that their current salaries were greater than those of program graduates in their firstjob. Of interest is that 1 in 5 (20%) of part-time/adjunct educators indicated the opposite--that program graduates earn more in their firstjob than educators earn. When asked about salaries if working full time in clinical practice, the majority of all groups indicated their salary would be about the same or would decrease. Only 20% of program

  18. Organizational decentralization in radiology.

    Aas, I H Monrad

    2006-01-01

    At present, most hospitals have a department of radiology where images are captured and interpreted. Decentralization is the opposite of centralization and means 'away from the centre'. With a Picture Archiving and Communication System (PACS) and broadband communications, transmitting radiology images between sites will be far easier than before. Qualitative interviews of 26 resource persons were performed in Norway. There was a response rate of 90%. Decentralization of radiology interpretations seems less relevant than centralization, but several forms of decentralization have a role to play. The respondents mentioned several advantages, including exploitation of capacity and competence. They also mentioned several disadvantages, including splitting professional communities and reduced contact between radiologists and clinicians. With the new technology decentralization and centralization of image interpretation are important possibilities in organizational change. This will be important for the future of teleradiology.

  19. Radiological protection in interventional radiology

    International Nuclear Information System (INIS)

    Padovani, R.

    2001-01-01

    Interventional radiology (IR) reduces the need for many traditional interventions, particularly surgery, so reducing the discomfort and risk for patients compared with traditional systems. IR procedures are frequently performed by non-radiologist physicians, often without the proper radiological equipment and sufficient knowledge of radiation protection. Levels of doses to patients and staff in IR vary enormously. A poor correlation exists between patient and staff dose, and large variations of dose are reported for the same procedure. The occurrence of deterministic effects in patients is another peculiar aspect of IR owing to the potentially high skin doses of some procedures. The paper reviews the use of IR and the radiological protection of patients and staff, and examines the need for new standards for IR equipment and the training of personnel. (author)

    This study was performed to understand the bacteriologic contamination level of radiological equipment which have frequent contacts with patients in the Department of Radiology of an university hospital in Busan area. Before sterilizing in-patient of the radiology rooms, MRSA, VRE, acinetobacter baumannii, candida albicans, and enterococcus sp. were detected. After sterilization, all the bacteria were not found. As examine times become longer, more bacteria were detected and after 7 hours, bacillus sp.(GPR), CNS, acinetobacter baumannii, and Enterococcus sp. were detected. After examining infected patients, bacillus sp.(GPR), VRE, enterococcus sp. CNS, and micrococcus sp. were detected and on the hands of radiological technologists, CNS, enterococcus sp. escherichia coli, and enterobacter sp. were detected. Similar species of bacteria were detected from each radiology room, but pseudomonas aeruginosa was detected on the handles of portable radiological equipment and the chair in the waiting room. Therefore, it is the most important to regularly sterilize radiological equipment and devices which have frequent contacts with patients and to sterilize them right after the use of infected patients in order to prevent the spread of infection. Also, thorough hand washing, education on infection and management for the characteristics of Department of Radiology should be performed for the systematic prevention of infection.

    1987-01-01

    Anesthetic techniques for neurodiagnostic studies and radiation therapy have been recently reviewed, but anesthetic involvement in thoracic and abdominal radiology has received little attention. Patient reactions to radiologic contrast media may be of concern to the anesthesiologist, who is often responsible for injecting these agents during diagnostic procedures, and thus is included in this discussion. Finally, the difficulties of administering anesthesia for magnetic resonance imaging (MRI) scans are outlined, in an effort to help anesthesiologist to anticipate problems with this new technologic development. Although there are very few indications for the use of general anesthesia for diagnostic radiologic studies in adults, most procedures performed with children, the mentally retarded, or the combative adult require either heavy sedation or general anesthesia. In selecting an anesthetic technique for a specific procedure, both the patient's disease process and the requirements of the radiologist must be carefully balanced

    Pervading the plans and objective outlined herein for continued and enhanced federal support of research in radiology is a challenge of unparalleled magnitude, for the economic foundation on which this support is based has rarely been more precarious. The new administration in Washington may well be the most fiscally constrained in half a century, and its stated interest in reducing federal expenditures could have disastrous consequences for the scientific research effort in this country, including that in radiology and the radiological sciences. The circumvention of these consequences may well require the dedicated effort of the entire scientific community over the next few months and years, including that part representing radiology and the radiological sciences

  8. Reduction of adult fingers visualized on pediatric intensive care unit (PICU) chest radiographs after radiation technologist and PICU staff radiation safety education

    International Nuclear Information System (INIS)

    Tynan, J.R.; Duncan, M.D.; Burbridge, B.E.

    2009-01-01

    A recent publication from our centre revealed a disturbing finding of a significant incidence of adult fingers seen on the pediatric intensive care unit (PICU) chest radiographs. This is inappropriate occupational exposure to diagnostic radiation. We hypothesized that the incidence of adult fingers on PICU chest radiographs would decline after radiation safety educational seminars were given to the medical radiation technologists and PICU staff. The present study's objectives were addressed by using a pretest-posttest design. Two cross-sectional PICU chest radiograph samples, taken before and after the administration of radiation safety education for our medical radiation technologists and PICU staff, were compared by using a χ 2 test. There was a 61.2% and 76.9% reduction in extraneous adult fingers, directly exposed to the x-ray beam and those seen in the coned regions of the film, respectively, on PICU chest radiographs (66.7% reduction overall). This reduction was statistically significant (χ2 = 20.613, P < .001). Limiting unnecessary occupational radiation exposure is a critical issue in radiology. There was a statistically and clinically significant association between radiation safety education and the decreased number of adult fingers seen on PICU chest radiographs. This study provides preliminary evidence in favour of the benefit of radiation safety seminars. (author)

    Radiological interventions possess wide utilization in the diagnosis and treatment for pediatric patients. Pediatric interventional radiology is an important branch of interventional radiology and also an important branch of pediatric radiology. Pediatric interventional radiology has grown substantially over the last 30 years, radiologists closely cooperation with surgeons and other physicians providing a new horizon in the management of pediatric diseases in western countries. It includes pediatric cardiac interventional radiology, pediatric neuro-interventional radiology, pediatric vascular interventional radiology, pediatric nonvascular interventional radiology, pediatric tumor interventional radiology and others. In the United States, every children hospital which owns two hundred beds has to have special trained interventional radiologists in radiologic department installing with advanced digital subtraction angiographic equipment. Interventional therapeutic procedures and diagnostic angiography have been proceeding more and more for the congenital and acquired diseases of children. The promising results give use uprising and interventional therapy as an alternative or a replacement or supplement to surgical operation. Pediatric interventional radiology is rather underdeveloped in China with a few special pediatric interventional radiologist, lack of digital subtraction angiography equipment. Pediatric radiologists have no enough field for interventional procedures such as pediatric neuro-interventional radiology and pediatric vascular interventional radiology. In the contrary adult interventional radiologists do have better interventional jobs in China and Pediatric cardiologists also share the same trend. They perform angiocardiography for congenital heart diseases and treat congenital heart disease with interventional procedures including balloon dilation of valves and vessels, coil embolization of collaterals, patent ducts and other arterial fistulae

  10. Strategic planning for radiology: opening an outpatient diagnostic imaging center.

    Leepson, Evan

    2003-01-01

    Launching a new diagnostic imaging center involves very specific requirements and roadmaps, including five major areas of change that have a direct impact on planning: Imaging and communication technology Finances and reimbursement Ownership structure of imaging entities Critical workforce shortages Imaging is moving outside radiology First, planning must focus on the strategic level of any organization, whether it is a multi-national corporation or a six-person radiology group. Think of all organizations as a triangle with three horizontal levels: strategic, managerial and operational. The strategic level of decision-making is at the top of the triangle, and here is where planning must take place. For strategic planning to work, there must be focused time and energy spent on this activity, usually away from the reading room and imaging center. There are five planning strategies, which must have the explicit goal of developing and growing the imaging center. The five strategies are: Clinical and quality issues, Governance and administration, Technology, Relationships, Marketing and business development. The best way to plan and implement these strategies is to create work groups of radiologists, technologists, and administrative and support staff. Once the group agrees on the strategy and tactic, it takes responsibility for implementation. Embarking on the launch of a new outpatient diagnostic imaging center is no small undertaking, and anyone who has struggled with such an endeavor can readily attest to the associated challenges and benefits. Success depends on many things, and one of the most important factors relates to the amount of time and the quality of effort spent on strategic planning at the outset. Neglecting or skimping on this phase may lead to unforeseen obstacles that could potentially derail the project.

    It is becoming increasingly important for today's medical technologists to receive proper training on the safety of medical treatment and healthcare in order to accommodate the rapid changes and advancement in medical technology. In particular, because of the increase of hospital-acquired infections, the role of medical technologists involved in infection control has become much more important. In addition, particularly in Japan, the career options available to students graduating with a degree in medical technology have become much more diverse, ranging from research laboratories to clinical services; however, undergraduate education for medical technologists is limited. It is therefore deemed necessary for undergraduate students to be provided with adequate training from their universities by offering a wider selection of classes in this subject area. In this paper, we summarize our preliminary findings on the trial lessons that are offered to medical technology students in their microbiology class. These lessons are designed to enhance students' academic potential and to engage their interest.

    Each facility is tasked with maintaining personnel radiation exposure as low as reasonably achievable (ALARA). A continued effort is required to meet this goal by developing and implementing improvements to technical work documents (TWDs) and work performance. A review of selected TWDs from most facilities shows there is a need to incorporate more radiological control requirements into the TWD. The Radioactive Work Permit (RWP) provides a mechanism to place some of the requirements but does not provide all the information needed by the worker as he/she is accomplishing the steps of the TWD. Requiring the engineers, planners and procedure writers to put the radiological control requirements in the work steps would be very easy if all personnel had a strong background in radiological work planning and radiological controls. Unfortunately, many of these personnel do not have the background necessary to include these requirements without assistance by the Radiological Control organization at each facility. In add...

    Full Text Available The professional content of sleep medicine has grown significantly over the past few decades, warranting the recognition of sleep medicine as an independent specialty. Because the practice of sleep medicine has expanded in Saudi Arabia over the past few years, a national regulation system to license and ascertain the competence of sleep medicine physicians and technologists has become essential. Recently, the Saudi Commission for Health Specialties formed the National Committee for the Accreditation of Sleep Medicine Practice and developed national accreditation criteria. This paper presents the newly approved Saudi accreditation criteria for sleep medicine physicians and technologists.

    Environmental monitoring in the vicinity of the Calvert Cliffs Nuclear Power Plant has been shown the radiation dose to the public from plant operation to be quite small. Calculations from the reported release rates yield 0.2 mrem whole body dose and 0.6 mrem skin dose for the calendar quarter of maximum release. Radioactivity discharges to the Chesapeake Bay have resulted in detectable concentrations of /sup 110m/Ag, 58 Co, and 60 Co in sediments and shellfish. The area yielding samples with detectable concentrations of plant effluents extends for roughly six miles up and down the western shore, with maximum values found at the plant discharge area. The radiation dose to an individual eating 29 doz oysters and 15 doz crabs (5 kg of each) taken from the plant discharge area would be about 4/1000 mrem whole body dose and 0.2 mrem gastrointestinal tract dose (about 0.007% and 0.5% of the applicable guidelines, respectively.) Comparison of these power plant-induced doses with the fluctuations in natural radiation dose already experienced by the public indicates that the power plant effects are insignificant. The natural variations are tens of times greater than the maximum doses resulting from Calvert Cliffs Power Plant. Although operations to date provide an insufficient basis to predict radiological impact of the Calvert Cliffs Plant over its operational lifetime, available data indicate that the plant should continue to operate with insignificant radiological impact, well within all applicable guidelines

    1987-01-01

    As medico-legal statistics show, compared with other branches of medicine, cases of liability of the radiologist or his assistants are relatively rare. The duty to exercise due care as set out in Paragraph 6 of the Austrian penal code or Paragraph 276 of the German civil code, respectively, provide a basic rule of law also for radiology. Due to the risk inherent in the investigation method, incidents in angiography cannot be totally excluded. Therefore, it is of utmost importance that all steps be taken with regard to staff, equipment and drugs to be able to deal with any complications and incidents that may arise. The courts of law require the employer to produce strongest exonerating evidence to prove that the duty to exercise due care in the selection and supervision of the assistants has been duly fulfilled. For the practical execution of radiological investigations of the digestive tract, also the RTA is responsible; her liability when performing an irrigoscopy is particularly great, as perforation of the intestine is often lethal. The introduction of the rectal tube into the vagina by mistake, with resultant injury or death of the patient, will regularly lead to conviction under penal law. (orig.) [de

    The purpose of this study was to investigate the form and content of the radiology reports from radiology clinics in Korea. One hundred and sixty six radiology reports from 49 radiology clinics were collected, and these reports were referred to the academic tertiary medical center from March 2008 to February 2009. These included reports for CT (n = 18), MRI (n = 146) and examinations not specified (n = 2). Each report was evaluated for the presence of required contents (demographics, technical information, findings, conclusion, the name, license number and signature of the radiologist and the referring facility). These requirements were based on the guideline of the American College of Radiology and the previous research. The name of the patient, the gender, the body part, the type of examination, the time of examination and the conclusion, the name of the radiologist and the name of facility were well recorded in over 90% of the radiology reports. However, the identification number of the patient, the referring facility, the referring physician, the use of contrast material, the clinical information, the time of dictation, the signature of the radiologist and the license number of the radiologist were poorly recorded (less than 50%). The optimal format of a radiology report should be established for reliable and valid communication with clinicians

    A purported benefit of digital imaging and archiving of radiographic procedures is the presumption of time savings to radiologists, radiology technologists, and radiology departmentpersonnel involved with processingfilms and managing theflimfile room. As part of the University of Washington's evaluation of Picture Archiving and Communication Systems (PACS)for the U.S. Army Medical Research and Development Command, a study was performed which evaluated the current operationalpractices of the film-based radiology department at the University of Washington Medical Center (UWMC). Industrial engineering time and motion studies were conducted to document the length of time requiredforfilm processing in various modalities, the proportion of the total exam time usedforfilm processing, the amount of time radiologists spent searchingfor and looking at images, and the amount of time file room personnel spent collating reports, making loans, updatingfilm jacket information, and purging files. This evaluation showed that better than one-half of the tasks in the file room may be eliminated with PACS and radiologists may save easily 10 percent of the time they spend reading films by no longer having to searchforfilms. Radiology technologists may also save as much as 10 percent of their time with PACS, although this estimate is subject to significant patient mix aberrations and measurement error. Given that the UWMC radiology department operates efficiently, similar improvements are forecast for other radiology departments and larger improvements areforecastfor less efficient departments.

    Aim: The use of PACS and the need for images and clinical data is increasing exponentially. This presentation will provide a historical overview of radiology information systems (RIS) and their interaction with hospital information systems (HIS), PACS systems and modalities. Materials and Methods: The various approaches to interfacing and integrating RIS and PACS systems will be described as well as their impact on radiology departmental work-flow and the productivity of radiologists, technologists and other RIS users. Specifically, the image-centric and RIS-centric approaches to PACS will be compared. Results: Instant access to vital clinical information enables radiology departments to go beyond simply managing processes to making fundamental improvements in productivity and care processes. Unity of design translates into simplicity of operations. Integration of historically separate applications makes the environment easier to support, reduces turnaround time, and improves patient care. Conclusion: Finally, insight on new technologies and future trends in PACS, system integration and work-flow strategies will be presented in light of delivery of both clinical images and clinical data

    Radiology is vital to the life-saving efforts of surgeons and other physicians, but precious time can be lost generating the images and transferring them to and from the operating room. Furthermore, hospitals are straining under the task of storing and managing the deluge of diagnostic films produced every year. A 300-bed hospital generates about 1 gigabyte (8 x 10 9 bits) of picture information every day and is legally bound to hold it for three to seven years--30 years in the case of silicosis or black lung disease, illnesses that may have relevance to future lawsuits. Consequently, hospital warehouses are filling with x-ray film and written reports that are important for analysis of patient histories, for comparison between patients, and for analyzing the progress of disease. Yet only a fraction of the information's potential is being used because access is so complicated. What is more, films are easily lost, erasing valuable medical histories

  8. The economics of interventional radiology

    International Nuclear Information System (INIS)

    Price, G.W.

    1988-01-01

    At a time when policy makers and regulators are scheming to reduce the costs and utilization of medical services, interventional radiology is poised for growth. Part of this potential for growth is based on wider acceptance of the procedures performed by interventional radiologists. A second factor in the growth potential is the relative value in cost of these procedures compared with alternative therapies. The author presents a discussion of the differences in the relative value of these procedures when performed by physicians of different specialties. This paper reviews the status of the economic climate in the health care delivery system and the role and potential growth of interventional radiology. This includes a review of current data on the utilization of interventional radiology procedures in the Medicare program. This overview includes a discussion of the initiatives of the federal government which directly impact interventional radiology

    Until today, most of the documentation of forensic relevant medical findings is limited to traditional 2D photography, 2D conventional radiographs, sketches and verbal description. There are still some limitations of the classic documentation in forensic science especially if a 3D documentation is necessary. The goal of this paper is to demonstrate new 3D real data based geo-metric technology approaches. This paper present approaches to a 3D geo-metric documentation of injuries on the body surface and internal injuries in the living and deceased cases. Using modern imaging methods such as photogrammetry, optical surface and radiological CT/MRI scanning in combination it could be demonstrated that a real, full 3D data based individual documentation of the body surface and internal structures is possible in a non-invasive and non-destructive manner. Using the data merging/fusing and animation possibilities, it is possible to answer reconstructive questions of the dynamic development of patterned injuries (morphologic imprints) and to evaluate the possibility, that they are matchable or linkable to suspected injury-causing instruments. For the first time, to our knowledge, the method of optical and radiological 3D scanning was used to document the forensic relevant injuries of human body in combination with vehicle damages. By this complementary documentation approach, individual forensic real data based analysis and animation were possible linking body injuries to vehicle deformations or damages. These data allow conclusions to be drawn for automobile accident research, optimization of vehicle safety (pedestrian and passenger) and for further development of crash dummies. Real 3D data based documentation opens a new horizon for scientific reconstruction and animation by bringing added value and a real quality improvement in forensic science.

    2014-06-01

    Purpose: The new ABR core exam integrates physics into clinical teaching, with an emphasis on understanding image quality, image artifacts, radiation dose and patient safety for each modality and/or sub-specialty. Accordingly, physics training of radiological residents faces a challenge. A traditional teaching of physics through didactic lectures may not fully fulfill this goal. It is also difficult to incorporate physics teaching in clinical practice due to time constraints. A dedicated physics rotation may be a solution. This study is to evaluate a full week physics workshop developed for the first year radiological residents. Methods: The physics rotation took a full week. It included three major parts, introduction lectures, hand-on experiences and observation of technologist operation. An introduction of basic concepts was given to each modality at the beginning. Hand-on experiments were emphasized and took most of time. During hand-on experiments, residents performed radiation measurements, studied the relationship between patient dose and practice (i.e., fluoroscopy), investigated influence of acquisition parameters (i.g., kV, mAs) on image quality, and evaluated image quality using phantoms A physics test before and after the workshop was also given but not for comparison purpose. Results: The evaluation shows that the physics rotation during the first week of residency in radiology is preferred by all residents. The length of a full week of physics workshop is appropriate. All residents think that the intensive workshop can significantly benefit their coming clinical rotations. Residents become more comfortable regarding the use of radiation and counseling relevant questions such as a pregnant patient risk from a CE PE examination. Conclusion: A dedicated physics rotation, assisting with didactic lectures, may fulfill the requirements of physics of the new ABR core exam. It helps radiologists deeply understand the physics concepts and more efficiently use

    With this work and employing the radioprotection criterion, the authors pretend to minimize the risks associated to this practice; without losing the quality of the radiologic image. Odontology should perform the following criterions: 1. Justification: all operation of practice that implies exposition to radiations, should be reweighed, through an analysis of risks versus benefits, with the purpose to assure, that the total detriment will be small, compared to resultant benefit of this activity. 2. Optimization: all of the exposures should be maintained as low as reasonable possible, considering the social and economic factors. 3. Dose limit: any dose limit system should be considered as a top condition, nota as an admissible level. (S. Grainger)

  20. Integrative teaching in Radiology. A survey

    Dettmer, S.; Weidemann, J.; Wacker, F.; Fischer, V.

    2015-01-01

    To survey integrative teaching in radiology at German universities. A questionnaire about radiological education was sent electronically to all 37 chairpersons of university radiology departments in Germany. The questions included the course type, teaching methods, concept, perception, and advantages and disadvantages of integrative teaching. Statistical analysis was performed with nonparametric statistics and chi-square test. The survey was considered representative with a return rate of 68%. Integrative teaching is established at 4/5 of all departments. Integrative teaching is well accepted with an acceptance rate that is significantly higher in so-called 'Modellstudiengaengen' (model courses of study) (100%) compared to conventional courses of study (72%). The advantages of integrative teaching include linking of content (92%) and preparation for interdisciplinary work (76%). The disadvantages include high effort (75%) and time (67%) for organization. Furthermore, there is a risk that basic radiological facts and knowledge cannot be conveyed and that the visibility of radiology as an independent discipline is lost. Conventional radiological teaching has a similarly high acceptance (84%) compared to integrative courses (76%). Integrative teaching has a high acceptance among chairpersons in radiology in Germany despite the greater effort. A good interdisciplinary collaboration is essential for integrative teaching and at the same time this can be conveyed to the students. However, the visibility of radiology as a discipline and the possibility to cover basic radiological content must be ensured. Therefore, both conventional courses and integrative teaching seems reasonable, especially in cross-disciplinary subjects such as radiology.

  1. Paediatric interventional radiology

    International Nuclear Information System (INIS)

    McLaren, Clare

    2014-01-01

    Paediatric interventional radiology (PIR) is a rapidly-growing subspecialty, which offers a wide range of procedures applicable to almost all areas of hospital paediatrics. There are many important differences between paediatric and adult practice in interventional radiology, including disease processes and treatment goals, anatomical considerations, periprocedural patient management, radiation exposure optimisation and legal aspects. The use of retrievable or absorbable interventional devices such as stents will probably become more widespread in PIR practice. Recent advances in the technology of imaging equipment have been accompanied by an increase in the complexity of the work done by the radiographer. These developments present challenges and opportunities related to training and maintenance of skills, staffing arrangements, and the potential for advanced practice. It is likely that specialisation in PIR will become a more common role for radiographers in the future

    Camargo, Aline; Liu, Li; Yousem, David M

    2017-09-01

    The purpose of this study is to assess medical ethics knowledge among trainees and practicing radiologists through an online survey that included questions about the American College of Radiology Code of Ethics and the American Medical Association Code of Medical Ethics. Most survey respondents reported that they had never read the American Medical Association Code of Medical Ethics or the American College of Radiology Code of Ethics (77.2% and 67.4% of respondents, respectively). With regard to ethics education during medical school and residency, 57.3% and 70.0% of respondents, respectively, found such education to be insufficient. Medical ethics training should be highlighted during residency, at specialty society meetings, and in journals and online resources for radiologists.

  3. Digital radiology and ultrasound

    Todd-Pokropek, A.

    1991-01-01

    With the access to digital methods for handling and processing images in general, many medical imaging methods are becoming more effectively handled digitally. This applies in particular to basically digital techniques such as CT and MR but also now includes Nuclear Medicine (NM), Ultrasound (US) and a variety of radiological procedures such as Digital Subtraction Angiography (DSA) and Fluoroscopy (DF). The access to conventional projection images by stimulatable plates (CR) or by digitization of film makes all of radiology potentially accessible, and the management of such images by a network is the basic aim of Picture Archiving and Communication Systems (PACS). However, it is suggested that in order for such systems to be of greater value, that way in which such images are treated needs to change, that is, digital images can be used to derive additional clinical value by appropriate processing

    Finlay, D.B.L.; Allen, M.J.

    1984-01-01

    This book is about radiology of fractures. While it contains sections of clinical features it is not intended that readers should rely entirely upon these for the diagnosis and management of the injured patient. As in the diagnosis and treatment of all medical problems, fracture management must be carried out in a logical step-by-step fashion - namely, history, examination, investigation, differential diagnosis, diagnosis and then treatment. Each section deals with a specific anatomical area and begins with line drawings of the normal radiographs demonstrating the anatomy. Accessory views that may be requested, and the indications for these, are included. Any radiological pitfalls for the area in general are then described. The fractures in adults are then examined in turn, their radiological features described, and any pitfalls in their diagnosis discussed. A brief note of important clinical findings is included. A brief mention is made of pediatric fractures which are of significance and their differences to the adult pattern indicated. Although fractures can be classified into types with different characteristics, in life every fracture is individual. Fractures by and large follow common patterns, but many have variations

  5. Introduction to radiological performance assessment

    Moss, G.

    1995-02-01

    A radiological performance assessment is conducted to provide reasonable assurance that performance objectives for low-level radioactive waste (LLW) disposal will be met. Beginning in the early stages of development, a radiological performance assessment continues through the operational phase, and is instrumental in the postclosure of the facility. Fundamental differences exist in the regulation of commercial and defense LLW, but the radiological performance assessment process is essentially the same for both. The purpose of this document is to describe that process in a concise and straightforward manner. This document focuses on radiological performance assessment as it pertains to commercial LLW disposal, but is applicable to US Department of Energy sites as well. Included are discussions on performance objectives, site characterization, and how a performance assessment is conducted. A case study is used to illustrate how the process works as a whole. A bibliography is provided to assist in locating additional information

    2013-01-01

    Qualitative research is lacking regarding the experiences of magnetic resonance imaging (MRI) technologists and their involvement in workplace safety practices. This article provides a gateway to explore, describe and document experiences of MRI technologists in New Zealand (NZ) pertaining to intra-orbital metallic foreign body (IMFB) safety practices. This phenomenological study describes the experiences of seven MRI technologists all with a minimum of 5 years' NZ work experience in MRI. The MRI technologists were interviewed face-to-face regarding their professional IMFB workplace experiences in order to explore historical, current and potential issues. Findings demonstrated that aspects of organization and administration are fundamentally important to MRI technologists. Varying levels of education and knowledge, as well as experience and skills gained, have significantly impacted on MRI technologists’ level of confidence and control in IMFB practices. Participants’ descriptions of their experiences in practice regarding decision-making capabilities further highlight the complexity of these themes. A model was developed to demonstrate the interrelated nature of the themes and the complexity of the situation in totality. Findings of this study have provided insight into the experiences of MRI technologists pertaining to IMFB safety practices and highlighted inconsistencies. It is hoped that these findings will contribute to and improve the level of understanding of MRI technologists and the practices and protocols involved in IMFB safety screening. The scarcity of available literature regarding IMFB safety practices highlights that more research is required to investigate additional aspects that could improve MRI technologists’ experiences

    Desjardins, Marc; Fleming, Christine Ann

    2014-08-01

    Accreditation in Ontario, Canada, requires that licensed clinical laboratories participate in external quality assessment (also known as proficiency testing) and perform competency evaluation of their staff. To assess the extent of ongoing competency assessment practices, the Quality Management Program--Laboratory Services (QMP-LS) Microbiology Committee surveyed all 112 licensed Ontario microbiology laboratories. The questionnaire consisted of a total of 21 questions that included yes/no, multiple-choice, and short-answer formats. Participants were asked to provide information about existing programs, the frequency of testing, what areas are evaluated, and how results are communicated to the staff. Of the 111 responding laboratories, 6 indicated they did not have a formal evaluation program since they perform only limited bacteriology testing. Of the remaining 105 respondents, 87% perform evaluations at least annually or every 2 years, and 61% include any test or task performed, whereas 16% and 10% focus only on problem areas and high-volume complex tasks, respectively. The most common methods of evaluation were review of external quality assessment (EQA) challenges, direct observation, and worksheet review. With the exception of one participant, all communicate results to staff, and most take remedial action to correct the deficiencies. Although most accredited laboratories have a program to assess the ongoing competency of their staff, the methods used are not standardized or consistently applied, indicating that there is room for improvement. The survey successfully highlighted potential areas for improvement and allowed the QMP-LS Microbiology Committee to provide guidance to Ontario laboratories for establishing or improving existing microbiology-specific competency assessment programs.

    Currently, Educational program of radiological science is developed in enormous growth, our educational environments leading allied health science education program in the number of super high speed medical industry. Radiological science may be the fastest growing technologies in our medical department today. In this way, Medical industry fields converged in the daily quick, the fact that department of radiological science didn't discharged ones duties on current educational environments. The curriculum of radiological technologists that play an important part between skill and occupation's education as major and personality didn't performed one's part most effectively on current medical environments and digital radiological equipment interface. We expect improvement and suggestion to grow natural disposition as studies in the graduate of radiological science. Therefore, in this paper, current curriculum of radiological science are catched hold of trend and problems on digital radiology environments, on fact the present state of problems, for Graduate program of radiological science, graduate courses of MS and ph.D. are suggested a reform measure of major education curriculum introduction

  14. Standing at the crossroads: Identity and recognition of the Applied Science Technologist in British Columbia

    Science.gov (United States)

    Roemer, Thomas

    Modern technical education in British Columbia has been affected by two societal trends: in industry, engineering technology evolved as a discipline to bridge the increasing chasm between the process-oriented skill sets of tradespersons/technicians, and the declarative knowledge focus of engineering; in education, the provincial college and institute system was created to address the need for a new post-secondary credential situated between trades certificates and university degrees. The Applied Science Technologist arguably forms the intersection of these two concepts. Almost forty years after its inception, it is timely to ask if the original model has matured into a distinct occupational category in industry, education, and in the public mind. The thesis proposes three environments, the Formative, Market and Public Domain, respectively. Interviews, surveys and personal experience afforded insights into the dynamics of these domains with respect to a fledgling occupational category, while the socio-philosophical concepts of culture, habitus and social imaginary provide the tools to interpret the findings. The thesis postulates that an emerging occupational category will not only challenge existing cultures and habitus, but that over time it will influence the imaginaries of each domain and society as a whole. Ultimately, the occupational category will be truly successful only when the general public is able to distinguish it from related disciplines. Charles Taylor's writings on multiculturalism are used to discuss identity and recognition of the Applied Science Technologist in each domain while Pierre Bourdieu's perspectives on the existence of habitus and self-proliferating elites form the framework to examine the relationships between technologists and engineers. Taylor's theory of multiple concurrent social imaginaries guides the comparison of divergent expectations among academic, career and vocational instructors at British Columbia's colleges. The thesis

  1. Radiological classification of mandibular fractures

    International Nuclear Information System (INIS)

    Mihailova, H.

    2009-01-01

    Mandibular fractures present the biggest part (up to 97%) of the facial bone fractures. Method of choice for diagnosing of mandibular fractures is conventional radiography. The aim of the issue is to present an unified radiological classification of mandibular fractures for the clinical practice. This classification includes only those clinical symptoms of mandibular fracture which could be radiologically objectified: exact anatomical localization (F1-F6), teeth in fracture line (Ta,Tb), grade of dislocation (D I, D II), occlusal disturbances (O(+), O(-)). Radiological symptoms expressed by letter and number symbols are systematized in a formula - FTDO of mandibular fractures similar to TNM formula for tumours. FTDO formula expresses radiological diagnose of each mandibular fracture but it doesn't include neither the site (left or right) of the fracture, nor the kind and number of fractures. In order to express topography and number of fractures the radiological formula is transformed into a decimal fraction. The symbols (FTD) of right mandible fracture are written in the numerator and those of the left site - in the denominator. For double and multiple fractures between the symbols for each fracture we put '+'. Symbols for occlusal disturbances are put down opposite, the fractional line. So topographo-anatomical formula (FTD/FTD)xO is formed. In this way the whole radiological information for unilateral, bilateral, single or multiple fractures of the mandible is expressed. The information in the radiological topography anatomic formula, resp. from the unified topography-anatomic classification ensures a quick and exact X-ray diagnose of mandibular fracture. In this way contributes to get better, make easier and faster X-ray diagnostic process concerning mandibular fractures. And all these is a precondition for prevention of retardation of the diagnosis mandibular fracture. (author)

    2016-01-01

    Since the discovery of radiation at the end of the 19. century, the health effects of exposure to radiation have been studied more than almost any other factor with potential effects on human health. The NEA has long been involved in discussions on the effects of radiation exposure, releasing two reports in 1994 and 2007 on radiological protection science. This report is the third in this state-of-the-art series, examining recent advances in the understanding of radiation risks and effects, particularly at low doses. It focuses on radiobiology and epidemiology, and also addresses the social science aspects of stakeholder involvement in radiological protection decision making. The report summarises the status of, and issues arising from, the application of the International System of Radiological Protection to different types of prevailing circumstances. Reports published by the NEA Committee on Radiation Protection and Public Health (CRPPH) in 1998 and 2007 provided an overview of the scientific knowledge available at that time, as well as the expected results from further research. They also discussed the policy implications that these results could have for the radiological protection system. The 2007 report highlighted challenges posed by developments in relation to medical exposure and by intentions to include the environment (i.e. non-human species), within the scope of the radiological protection system. It also addressed the need to be able to respond to a radiological terrorist attack. This report picks up on where the 1998 and 2007 reports left off, and addresses the state of the art in radiological prevention science and application today. It is divided into five chapters. Firstly, following broadly the structural topics from the 1998 and 2007 reports, the more purely scientific aspects of radiological protection are presented. These include cancer risk of low dose and dose rates, non-cancer effects and individual sensitivity. In view of the increasing

    International Nuclear Information System (INIS)

    O'Sullivan, Patrick; Ljubenov, Vladan

    2012-01-01

    Requirements for characterization of radiological and other hazards in nuclear facilities are reflected in the IAEA Safety Standards. WS-R-5, Safety Requirements for Decommissioning of Facilities using Radioactive Material, includes a requirement that 'During the preparation of the final decommissioning plan, the extent and type of radioactive material (irradiated and contaminated structures and components) at the facility shall be determined by means of a detailed characterization survey and on the basis of records collected during the operational period'. The subsidiary Safety Guide WS-G-2.1, Decommissioning of Nuclear Power Plants and Research Reactors, further elaborates that 'A survey of radiological and non-radiological hazards provides an important input for the safety assessment and for implementing a safe approach during the work'. Although the characterisation requirements addressed in the Safety Standards relate primarily to the detailed survey activities undertaken following the shutdown of the facility, it is evident that radiological characterization is of relevance to all major phases of the lifetime of a nuclear facility, including: - the siting phase - baseline surveys are undertaken to determine background radiation levels; - the construction phase - construction materials are retained to support future calculations of radioactivity distributions; - the operational phase - surveys are done regularly, with additional surveys being required following incidents involving plant contamination; - the transition phase - detailed radiological surveys are required to support the development of the final decommissioning plan; and - the closure phase - a final survey of the site and any remaining structures will be needed to support an application for release of the site from regulatory control. In the case of facilities that are already shut down, the main purpose of radiological characterisation is to provide a reliable database of information on the

    2015-04-01

    To survey integrative teaching in radiology at German universities. A questionnaire about radiological education was sent electronically to all 37 chairpersons of university radiology departments in Germany. The questions included the course type, teaching methods, concept, perception, and advantages and disadvantages of integrative teaching. Statistical analysis was performed with nonparametric statistics and chi-square test. The survey was considered representative with a return rate of 68 %. Integrative teaching is established at 4/5 of all departments. Integrative teaching is well accepted with an acceptance rate that is significantly higher in so-called "Modellstudiengängen" [model courses of study] (100 %) compared to conventional courses of study (72 %). The advantages of integrative teaching include linking of content (92 %) and preparation for interdisciplinary work (76 %). The disadvantages include high effort (75 %) and time (67 %) for organization. Furthermore, there is a risk that basic radiological facts and knowledge cannot be conveyed and that the visibility of radiology as an independent discipline is lost. Conventional radiological teaching has a similarly high acceptance (84 %) compared to integrative courses (76 %). Integrative teaching has a high acceptance among chairpersons in radiology in Germany despite the greater effort. A good interdisciplinary collaboration is essential for integrative teaching and at the same time this can be conveyed to the students. However, the visibility of radiology as a discipline and the possibility to cover basic radiological content must be ensured. Therefore, both conventional courses and integrative teaching seems reasonable, especially in cross-disciplinary subjects such as radiology. Both integrative teaching and conventional radiological teaching are highly accepted. The advantages include the linking of multidisciplinary content and the preparation for interdisciplinary cooperation

  9. Radiological Work Planning and Procedures

    International Nuclear Information System (INIS)

    KURTZ, J.E.

    2000-01-01

    Each facility is tasked with maintaining personnel radiation exposure as low as reasonably achievable (ALARA). A continued effort is required to meet this goal by developing and implementing improvements to technical work documents (TWDs) and work performance. A review of selected TWDs from most facilities shows there is a need to incorporate more radiological control requirements into the TWD. The Radioactive Work Permit (RWP) provides a mechanism to place some of the requirements but does not provide all the information needed by the worker as he/she is accomplishing the steps of the TWD. Requiring the engineers, planners and procedure writers to put the radiological control requirements in the work steps would be very easy if all personnel had a strong background in radiological work planning and radiological controls. Unfortunately, many of these personnel do not have the background necessary to include these requirements without assistance by the Radiological Control organization at each facility. In addition, there seems to be confusion as to what should be and what should not be included in the TWD

    The most important radiologically detectable effects of the primary and secondary hyperparathyroidism of the skeletal system and the periarticular soft tissue structures are presented. In the following sensitivity and specificity of radiological imaging - sonography, scintigraphy, computed tomography, magnetic resonance imaging, arteriography and selective venous sampling - in the preoperative diagnostic of the parathyroid adenomas are discussed. Therefore, radiological imaging can be omitted before primary surgery. It was only in secondary surgery that radiological process proved useful and a guide during surgical intervention. (orig.) [de

  12. Radiology education: a radiology curriculum for all medical students?

    Science.gov (United States)

    2017-09-26

    Diagnostic errors in radiology are frequent and can cause severe patient harm. Despite large performance differences between radiologists and non-radiology physicians, the latter often interpret medical images because electronic health records make images available throughout the hospital. Some people argue that non-radiologists should not diagnose medical images at all, and that medical school should focus on teaching ordering skills instead of image interpretation skills. We agree that teaching ordering skills is crucial as most physicians will need to order medical images in their professional life. However, we argue that the availability of medical images is so ubiquitous that it is important that non-radiologists are also trained in the basics of medical image interpretation and, additionally in recognizing when radiological consultancy should be sought. In acute situations, basic image interpretations skills can be life-saving. We plead for a radiology curriculum for all medical students. This should include the interpretation of common abnormalities on chest and skeletal radiographs and a basic distinction of normal from abnormal images. Furthermore, substantial attention should be given to the correct ordering of radiological images. Finally, it is critical that students are trained in deciding when to consult a radiologist.

    The purpose of this study was to provide an introduction to parsing the radiologic appearance of thoracic vertebrae and ribs. In the study, the radiologic-anatomic correlation technique was applied to promote further understanding of normal chest radiographs. The thoracic vertebrae and ribs of chest radiographs were compared with each macroscopic radiologic and computed tomography (CT) image. The rib parsed the linear shadow of the body of the rib. The macroscopic and radiologic images of thoracic vertebrae and ribs were evaluated to explain their normal radiologic findings. The results of such correlation were summarized as follows: The lamina of the vertebral arch was visualized due to anterior rotation of the upper thoracic vertebrae. The density ratio of the thoracic-vertebrae shadow was almost the same in the vertebral body and vertebral arch. The linear shadow superimposed on the rib corresponded to the inferior margin of the rib. The radiologic-anatomic correlation technique was useful to evaluate normal radiologic findings, and the study was useful to radiological technologists. (author)

    To investigate the ability to successfully develop and institute a comprehensive health care economics skills curriculum in radiology residency training utilizing didactic lectures, case scenario exercises, and residency miniretreats. A comprehensive health care economics skills curriculum was developed to significantly expand upon the basic ACGME radiology residency milestone System-Based Practice, SBP2: Health Care Economics requirements and include additional education in business and contract negotiation, radiology sales and marketing, and governmental and private payers' influence in the practice of radiology. A health care economics curriculum for radiology residents incorporating three phases of education was developed and implemented. Phase 1 of the curriculum constituted basic education through didactic lectures covering System-Based Practice, SBP2: Health Care Economics requirements. Phase 2 constituted further, more advanced didactic lectures on radiology sales and marketing techniques as well as government and private insurers' role in the business of radiology. Phase 3 applied knowledge attained from the initial two phases to real-life case scenario exercises and radiology department business miniretreats with the remainder of the radiology department. A health care economics skills curriculum in radiology residency is attainable and essential in the education of future radiology residents in the ever-changing climate of health care economics. Institution of more comprehensive programs will likely maximize the long-term success of radiology as a specialty by identifying and educating future leaders in the field of radiology.

    Background: Diseases exhibiting osteolysis in children are rare hereditary conditions. Several types have been recognised with different clinical manifestations. One type includes subcutaneous nodules, arthropathy and osteolysis and has been termed NAO syndrome. Previous radiological reports have described the affected bones, usually the carpal and tarsal regions, but a detailed analysis of the radiological findings of both the axial as well as the appendicular skeleton has not been reported. Objectives: To describe the radiological findings in a large group of children with an autosomal recessive disease characterized by nodules, familial arthropathy and osteolysis. Materials and methods: The study comprises 14 patients from 9 families and all patients had the triad of nodulosis, arthropathy and osteolysis (NAO). Results: The most common radiological manifestations were osteopenia, undertubulation of long bones, arthritic changes, sclerotic sutures of the calvaria, osteolysis and muscle contractures. Other common findings were squared vertebrae, broad medial clavicles and brachycephaly. Progress of disease was documented in more than half of the patients. Conclusions: Our study is the first report of the detailed radiological findings of NAO syndrome. In NAO syndrome, both the axial and appendicular skeleton are involved (orig.)

    This study assesses the inter-observer variability of mammographic breast density scoring (BDS) between technologists and radiologists and evaluates the effect of technologist patient referral on the load of adjuvant ultrasounds. In this IRB approved study, a retrospective analysis of 503 prospectively acquired, random mammograms was performed between January and March 2014. Each mammogram was evaluated for BDS independently and blindly by both the performing technologist and the interpreting radiologist. Statistical calculation of the Spearman correlation coefficient and weighted kappa were obtained to evaluate the inter-observer variability between technologists and radiologists and to examine whether it relates to the technologist's seniority or women's age. The effect on the load of adjuvant ultrasounds was evaluated. 10 mammography technologists and 7 breast radiologists participated in this study. BDS agreement levels between technologists and radiologists were in the fair to moderate range (kappa values: 0.3-0.45, Spearman coefficient values: 0.59-0.65). The technologists markedly over-graded the density compared to the radiologists in all the subsets evaluated. Comparison between low and high-density groups demonstrated a similar trend of over-grading by technologists, who graded 51% of the women as having dense breasts (scores 3-4) compared to 27% of the women graded as such by the radiologists. This trend of over grading breast density by technologists was unrelated to the women's age or to the technologists' seniority. Mammography technologists over-grade breast density. Technologists' referral to an adjuvant ultrasound leads to redundant ultrasound studies, unnecessary breast biopsies, costs and increased patient anxiety. Copyright © 2016 Elsevier Ireland Ltd.

  2. Microsystems technologist workforce development capacity and challenges in Central New Mexico.

    Energy Technology Data Exchange (ETDEWEB)

    Osborn, Thor D.

    2008-04-01

    Sandia National Laboratories has made major investments in microsystems-related infrastructure and research staff development over the past two decades, culminating most recently in the MESA project. These investment decisions have been made based in part upon the necessity for highly reliable, secure, and for some purposes, radiation-hardened devices and subsystems for safety and sustainability of the United States nuclear arsenal and other national security applications. SNL's microsystems development and fabrication capabilities are located almost entirely within its New Mexico site, rendering their effectiveness somewhat dependent on the depth and breadth of the local microsystems workforce. Consequently, the status and development capacity of this workforce has been seen as a key personnel readiness issue in relation to the maintenance of SNL's microsystems capabilities. For this reason SNL has supported the instantiation and development of the Southwest Center for Microsystems Education, an Advanced Technology Education center funded primarily by the National Science Foundation, in order to foster the development of local training capacity for microsystems technologists. Although the SCME and the associated Manufacturing Technology program at Central New Mexico Community College have developed an effective curriculum and graduated several highly capable microsystems technologists, the future of both the center and the degree program remain uncertain due to insufficient student enrollment. The central region of New Mexico has become home to many microsystems-oriented commercial firms. As the demands of those firms for technologists evolve, SNL may face staffing problems in the future, especially if local training capacity is lost.

    1982-01-01

    The dictionary of radiology is based on practical experience in diagnostic radiology. Following a brief clinical introduction, radiological methods including nuclear medicine and the increasingly important field of sonography are presented in alphabetic order, each term with a short definition. The most favourable order of application is determined by the diagnostic value, technical requirements and discomfort of the various methods. Preparative measures, the duration of the examinations, and problems of radiation hygiene are discussed. Illustrative drawings supplement the text. The fields of application given for the various methods are based on the latest state of knowledge. Other methods, e.g. endoscopy in all its variants and thermography, are mentioned whereever they are of diagnostic value. The book has a brief appendix in which the fundamental physical and technical context are explained, also in alphabetic order. Detailed cross-references establish a connection between diseases and diagnostic methods, thus facilitating access to the desired information.

    Due to increasing cardiac disease and its mortality rate, the frequency of cardiac imaging has grown and, as a result, interventional cardiologists potentially receive high radiation doses in cardiac examinations. This study aimed to assess the knowledge, attitude, and practice (KAP) level of radiation protection (RP) among interventional radiology staff in Iranian health care centers across the country. We used a validated questionnaire survey consisting of 30 multiple-choice questions to perform a cross-sectional study. Participants were healthcare personnel working professionally with radiation at different levels (i.e., secretary, radiology technologists, nurse, and physician). The questionnaire was divided into three sections to assess KAP regarding RP. Significant differences exist in RP KAP mean scores based on educational age (p 0.050). We found a significant difference between RP KAP mean scores and different regions (p < 0.050). Educational and practice age, sex, type of hospital, and geographical region affect he KAP of interventional radiology staff regarding RP. Since many of the subjective radiation harms for both medical team and patients, this can be easily controlled and prevented; a checkup for personnel of interventional radiology departments, considering samples from different parts of the country with different levels of education, continuous training, and practical courses may help map the status of KAP. The results of this study may also help authorized health physics officers design strategic plans to enhance the quality of such services in radiation departments.

    2012-07-01

    The radiologic aesthetics of some body parts and internal organs have inspired certain artists to create specific works of art. Our aim was to describe the link between radiology and fine art. We explored 13,625 artworks in the literature produced by 2049 artists and found several thousand photographs in an online image search. The examination revealed 271 radiologic artworks (1.99%) created by 59 artists (2.88%) who mainly applied radiography, sonography, CT, and MRI. Some authors produced radiologic artistic photographs, and others used radiologic images to create artful compositions, specific sculptures, or digital works. Many radiologic artworks have symbolic, metaphoric, or conceptual connotations. Radiology is clearly becoming an original and important field of modern art.

    Traditionally, the pediatric radiology elective for medical students and pediatric residents constituted a morning teaching session focused mainly on radiography and fluoroscopy. A more structured elective was desired to broaden the exposure to more imaging modalities, create a more uniform educational experience, and include assessment tools. In 2012, an introductory e-mail and formal syllabus, including required reading assignments, were sent to participants before the start date. A rotating weekly schedule was expanded to include cross-sectional imaging (ultrasound, CT, MR) and nuclear medicine. The schedule could accommodate specific goals of the pediatric resident or medical student, as requested. Starting in 2013, an online pre-test and post-test were developed, as well as an online end-of-rotation survey specific to the pediatric radiology elective. Taking the Image Gently pledge was required. A scavenger hunt tool, cue cards, and electronic modules were added. Pre-test and post-test scores, averaged over 2 years, showed improvement in radiology knowledge, with scores increasing by 27% for medical students and 21% for pediatric residents. Surveys at the end of the elective were overwhelmingly positive, with constructive criticism and complimentary comments. We have successfully created an elective experience in radiology that dedicates time to education while preserving the workflow of radiologists. We have developed tools to provide a customized experience with many self-directed learning opportunities. Our tools and techniques are easily translatable to a general or adult radiology elective.

    Magnetic resonance imaging is proving to be a powerful diagnostic modality. Included in this year's abstracts and discussions are papers having to do with it application to neoplasia in general and a variety of specific disorders of the brain and spinal column. Magnetic resonance spectroscopy is reported; whether or not this becomes practical, it is an exciting prospect. Perhaps because interventional techniques are so readily applicable at this time, both in the infant and child as well as in the adult, little has been included. On the other hand, some disorders that were in the province of adult medicine are now becoming distressingly common in infants and children, i.e., the adult respiratory distress syndrome; the acquired immune deficiency syndrome and AIDS-related complex; and aluminum bone disease in children. Of those developments that are promising and related to the infant or child, one can count the articles having to do with extracorporeal membrane oxygenation and the treatment of the respiratory distress syndrome, hyaline membrane disease, with human surfactant. The latter raises expectations for the end of multiple examinations of the sick neonate necessary for the definition and follow-up of pulmonary interstitial emphysema and the other complications of air block phenomenon. The two contributions on the role of diagnostic imaging before and after transplantation of the liver serve as a reference

  12. Expanding the scope of practice for radiology managers: radiation safety duties.

    Orders, Amy B; Wright, Donna

    2003-01-01

    In addition to financial responsibilities and patient care duties, many medical facilities also expect radiology department managers to wear "safety" hats and complete fundamental quality control/quality assurance, conduct routine safety surveillance in the department, and to meet regulatory demands in the workplace. All managers influence continuous quality improvement initiatives, from effective utilization of resource and staffing allocations, to efficacy of patient scheduling tactics. It is critically important to understand continuous quality improvement (CQI) and its relationship with the radiology manager, specifically quality assurance/quality control in routine work, as these are the fundamentals of institutional safety, including radiation safety. When an institution applies for a registration for radiation-producing devices or a license for the use of radioactive materials, the permit granting body has specific requirements, policies and procedures that must be satisfied in order to be granted a permit and to maintain it continuously. In the 32 U.S. Agreement states, which are states that have radiation safety programs equivalent to the Nuclear Regulatory Commission programs, individual facilities apply for permits through the local governing body of radiation protection. Other states are directly licensed by the Nuclear Regulatory Commission and associated regulatory entities. These regulatory agencies grant permits, set conditions for use in accordance with state and federal laws, monitor and enforce radiation safety activities, and audit facilities for compliance with their regulations. Every radiology department and associated areas of radiation use are subject to inspection and enforcement policies in order to ensure safety of equipment and personnel. In today's business practice, department managers or chief technologists may actively participate in the duties associated with institutional radiation safety, especially in smaller institutions, while

    The book conveys the knowledge indispensable to diagnostic radiologists in emergency wards. Its material is divided under anatomical viewpoints. The individual forms of fracture are briefly described. Normal anatomy in the X-ray picture, pitfalls in diagnostics, possibilities of error and differential diagnosis are discussed in individual chapters each. All essential diagnoses are illustrated by highly informative pictures with detailed legends. The book is not restricted to the description of bone fractures but includes as well the X-ray diagnosis of traumatized thoracal and abdominal organs. It proves to be up to date with the current state of knowledge by discussing furthermore the possibilities of computerized tomography and diagnostic methods using isotopes and ultrasonic waves.

    2001-01-01

    The spleen is generally not considered a challenge to the radiologist. Most often it poses a problem by anomalies or an irregular but normal contrast enhancement; however, a variety of inflammatory, infectious and neoplastic diseases may involve the spleen. CT and ultrasonography are screening modalities for the spleen. For problem solving, MR imaging can be helpful, especially due to its free choice of the imaging plane and because of the high resolution in contrast MR imaging. Splenic angiography as a diagnostic tool has generally been replaced by CT, ultrasound, or MR and is now used as an interventional method, e.g., in non-surgical management of patients with chronic idiopathic thrombocytopenia or in patients with splenic trauma. This article reviews the radiology of the spleen, including anatomy, embryology, splenomegaly, splenic injury, infarction, cysts, tumors, abscesses, sarcoidosis, and AIDS. Knowledge about the use of different imaging modalities and underlying gross and microscopic pathologic features leads to a better understanding of the radiologic findings. (orig.)

    To gauge the prevalence of sexual harassment (SH) and to understand the issues regarding its disclosure among radiologists. A questionnaire on ethics and SH was sent by e-mail to 1,569 radiologists and radiology trainees in an institutional database maintained for continuing medical education purposes on three separate occasions between September 17 and October 31, 2016. The link to the survey was also posted on social media sites via the authors' divisional and institutional accounts on Facebook, Twitter, Instagram, and Aunt Minnie, as well as on ACR and RSNA web blogs. Overall, 9.75% (39 of 400) respondents stated they had suffered SH, with more female (22 of 90 = 24.4%) than male victims (11 of 249 = 4.4%) (P school graduates (119 of 220 = 54.1%) were less likely than graduates from outside the United States (37 of 48 = 77.1%). Of 401 respondents to questions on SH, 28.7% (n = 115), including more women (38 of 91 = 41.8%) than men (61 of 249 = 24.5%) (P = .002), said they had witnessed SH. By percentage responding, female radiologists are more frequently victims and witnesses of sexual harassment but are less likely to report such cases. Steps need to be taken to eliminate a culture that leads radiologists to tolerate SH without addressing it. Copyright © 2017 American College of Radiology. Published by Elsevier Inc.

    Huepscher, D.N.

    1988-01-01

    Before the radiologist can decide on his approach to the examination, he needs clinical information and a short relevant medical history of the patient. These aspects are considered in Chapter 1. Chapter 2 covers the 'standard' examination of the esophagus, the contrast media, the relative values of the single contrast, mucosal relief and double contrast studies, the various techniques used to obtain double contrast films and, finally, several of the drugs administered during the examination. Since in cases of aspecific dysphagia the entire esophagus - including the pharynx - must be examined, this stepchild of the radiological examination is the focus of attention in Chapter 3 while an overview of the anatomy, physiology, roentgen anatomy and roentgen physiology of the esophageal body is presented in Chapter 4. Congenital abnormalities, displacement and impressions, diverticula, foreign bodies, perforation and tumors are considered in more detail in Chapters 5 to 10, respectively. The value of computed tomography for the staging of esophageal cancer is discussed in Chapter 11. Chapter 12 is devoted to the highly diversified spectrum of abnormalities of the esophageal wall. Disturbed motility is the subject of Chapter 13. In Chapter 14 the hiatal hernia, gastroesophageal reflux and its results are discussed in a somewhat broader context. In Chapter 15 the radiological aspects of the postoperative esophagus are described. (orig./MG)

    In the other sections, one finds discussions of lesions or disorders that are congenital in nature, that are genetically determined, and that are acquired. Others that involve the lung of the child may in fact be encountered in the adult as well, e.g., cystic adenomatoid malformation, knowledge of which will provide another basis for a more encompassing differential diagnosis of some curious or poorly understood problems. Some would appear to be quite rare, and one might wonder why they should be included, e.g., plastic bronchitis and immotile cilia syndrome. The radiologist is the one who may well see the patient with chronic pulmonary disease on repeated occasions and suggest an approximate differential diagnosis that may result in a definitive diagnosis. One must know the possibilities, however, in order to construct such a differential. There are papers dealing with hydatid disease and amebiasis, uncommon to be sure, but these diseases have been encountered in Boston an I am sure elsewhere as the world gets smaller and travel becomes available to more people. Again, it is the radiologist who might be the first to suspect the underlying disease. There is a follow-up to an interesting article that occurred in the 1984 YEAR BOOK (article 6-1) that has to do with the role of surgical intervention in utero. The abstracted paper concerned with the prenatal diagnosis of obstructive uropathy and the comments by Doctor Lebowitz that are included this year are pertinent as intrauterine diagnosis and potential therapy become better understood and defined. The dysfunction of collagen-dificient osteogenesis imperfecta is of interest because of its importance and relevance to the diagnosis of the osseous dysplasias; its elucidation will become more and more the province of the enzyme chemist or the biochemist as opposed to reliance on gross morphology

    In Japan, the primary 'baby-boomer' generation, born between 1947 and 1949, is now in its retirement. This has caused a marked shortage of human resources nationwide. Clinical laboratory technologists are no exception, and many clinical laboratories in Japanese healthcare facilities are struggling with management because the number of new graduates, i.e., newly licensed technologists, is mostly fixed and, therefore, their recruitment is becoming more and more competitive. Our laboratory is now facing a wave of mass-retirement associated with our history. In addition, in the early 2000s, there was almost no position for new graduates replacing those retiring because of the change in the social healthcare system as well as our hospital's policy. This resulted in uneven numbers of technologists in generations, and it seemed to be getting worse. Fortunately, five years ago, the direction of social health care was changed and lots of positions became available as a result. We have been trying to recruit new graduates and experienced technologists as well, and were able to hire 18 people. Among them, 8 were non-freshmen. The generation gap has been mostly resolved. We will continue to make our laboratory more attractive not just to new graduates but also to experienced technologists, especially those who wish to return to work after a several-year absence to raise their children. We believe that this will energize our laboratory.

    1980-01-01

    To provide medical and scientific background on certain selected technologies generally considered to be of particular significance, the National Center for Health Care Technology (NCHCT) has commissioned a series of overview papers. This is one of several projects entered into jointly by the Bureau of Radiological Health (BRH) and NCHCT relating to the use of radiation for health care. Dental radiation protection has been a long-time interest of BRH. Both past and on-going efforts to minimize population radiation exposure from electronic products have included specific action programs directed at minimizing unnecessary radiation exposure to the population from dental radiology. Current efforts in quality assurance and referral criteria are two aspects of NCHCT's own assessment of this technology which are described within the larger picture presented in this overview. The issues considered in this document go beyond the radiation exposure aspects of dental x-ray procedures. To be responsive to the informational needs of NCHCT, the assessment includes various other factors that influence the practice of dental radiology. It is hoped this analysis will serve as the basis for planning and conducting future programs to improve the practice of dental radiology

  1. Radiologic examination

    Thoeni, R.F.

    1989-01-01

    The radiographic examination of the upper and lower gastrointestinal tract has been changed drastically by the introduction of endoscopic procedures that are now widely available. However, the diagnostic approach to the small bowel remains largely unchanged. Ultrasonography, computed tomography (CT), and magnetic resonance imaging (MRI) are occasionally employed but are not primary imaging modalities for small bowel disease. Even though small bowel endoscopes are available, they are infrequently used, and no scientific paper on their employment has been published. Barium studies are still the mainstay for evaluating patients with suspected small bowel abnormalities. This paper discusses the anatomy and physiology of the small bowel and lists the various types of barium and pharmacologic aids used for examining it. The different radiographic methods for examining the small bowel with barium, including SBFT, dedicated SBFT, enteroclysis, peroral pneumocolon (PPC), and retrograde small bowel examination, are described and put into perspective. To some degree such an undertaking must be a personal opinion, but certain conclusions can be made based on the available literature and practical experience. This analysis is based on the assumption that all the various barium techniques are performed with equal expertise by the individual radiologist, thus excluding bias from unfamiliarity with certain aspects of a procedure, such as intubation or skilled compression during fluoroscopy. Also, the use of water-soluble contrast material, CT, and MRI for evaluating suspected small bowel abnormalities is outlined

    Skills and knowledge regarding many different types of test are required for medical technologists (MTs) to provide accurate information to help doctors and other medical specialists. In order to become an efficient MT, specialized training programs are required. Certification in specialized areas of clinical laboratory sciences or a doctoral degree in medical sciences may help MTs to realize career advancement, a higher earning potential, and expand the options in their career. However, most young MTs in national university hospitals are employed as part-time workers on a three-year contract, which is too short to obtain certifications or a doctoral degree. We have to leave the hospital without expanding our future. We need to take control of our own development in order to enhance our employability within the period. As teaching and training hospitals, national university hospitals in Japan are facing a difficult dilemma in nurturing MTs. I hope, as a novice medical technologist, that at least university hospitals in Japan create an appropriate workplace environment for novice MTs.

  3. Radiological instrument

    International Nuclear Information System (INIS)

    Kronenberg, S.; McLaughlin, W.L.; Seibentritt, C.R. Jr.

    1986-01-01

    An instrument is described for measuring radiation, particularly nuclear radiation, comprising: a radiation sensitive structure pivoted toward one end and including a pair of elongated solid members contiguously joined together along their length dimensions and having a common planar interface therebetween. One of the pairs of members is comprised of radiochromic material whose index of refraction changes due to anomolous dispersion as a result of being exposed to nuclear radiation. The pair of members further has mutually different indices of refraction with the member having the larger index of refraction further being transparent for the passage of light and of energy therethrough; means located toward the other end of the structure for varying the angle of longitudinal elevation of the pair of members; means for generating and projecting a beam of light into one end of the member having the larger index of refraction. The beam of light is projected toward the planar interface where it is reflected out of the other end of the same member as a first output beam; means projecting a portion of the beam of light into one end of the member having the larger index of refraction where it traverses therethrough without reflection and out of the other end of the same member as a second output beam; and means adjacent the structure for receiving the first and second output beams, whereby a calibrated change in the angle of elevation of the structure between positions of equal intensity of the first and second output beams prior to and following exposure provides a measure of the radiation sensed due to a change of refraction of the radiochromic material

    2011-01-01

    Radiological and pathological imaging constitute an essential part of modern medicine. Furthermore, by showing microscopic and radiological images many pathological processes can be made clearer and easier to understand. This has consequences for education. Many medical faculties are switching partly or entirely to the use of 'virtual microscopy', which amounts to studying digitalised histological preparations with the help of software that shows striking similarities to Google Earth. The requesting physician of the future will be able to make the most effective use of radiological tests when he or she has been trained in 'radiological thinking'. Students must realise that radiology depends not just on looking, as one might at holiday snaps, but more especially on interpreting what is seen. By using modern aids, it is possible to test the listeners' knowledge during lectures as a basis for the rest of the presentation. Collections of educational images are now widely available, including on the Internet.

    1998-01-01

    For radiology the socioeconomic environment is a topic of increasing importance. In addition to the well-known important scientific developments in radiology such as interventional MRI, several other major trends can be recognized: (1) changes in the delivery of health care, in which all kinds of managed care are developing and will influence the practice of radiology, and (2) the process of computerization and digitization. The socioeconomic environment of radiology will be transformed by the developments in managed care, teleradiology and the integration of information systems. If radiologists want to manage future radiology departments they must have an understanding of the changes in the fields of economics and politics that are taking place and that will increasingly influence radiology. Some important and recognizable aspects of these changes will be described here. (orig.)

    This second edition of Radiology of Osteoporosis has been fully updated so as to represent the current state of the art. It provides a comprehensive overview of osteoporosis, the pathologic conditions that give rise to osteoporosis, and the complications that are frequently encountered. After initial chapters devoted to pathophysiology, the presentation of osteoporosis on conventional radiographs is illustrated and discussed. Thereafter, detailed consideration is given to each of the measurement methods employed to evaluate osteoporosis, including dual x-ray absorptiometry, vertebral morphometry, spinal and peripheral quantitative computed tomography, quantitative ultrasound, and magnetic resonance imaging. The role of densitometry in daily clinical practice is appraised. Finally, a collection of difficult cases involving pitfalls is presented, with guidance to their solution. The information contained in this volume will be invaluable to all with an interest in osteoporosis. (orig.)

    E-mail is an Internet service that can be used for sending messages and binary files between individuals as well as for participating in discussion groups. For sending and receiving these types of messages, the users must use either a dedicated e-mail client or one of the several mailing facilities of the World Wide Web. The newsgroups enable likeminded people to discuss subjects on a group-wide basis, but access is generally not limited, and the participants cannot be selected. Conclusion: The objective of this paper is to give radiologists an introduction to using e-mail, mailing lists and newsgroups, the three most important communication services of the Internet. The function of these services is explained, and the advantages of implementing them in a radiology practice are discussed. Potential problems and concerns including security matters are highlighted, and ways in which they can be resolved are suggested. (orig.) [de

    Hamley, S.A.

    1993-01-01

    A manual is being developed to explain to line managers how radiological controls are designed and implemented. The manual also fills a gap in the Health Physics literature between textbooks and on-the-floor procedures. It may be helpful to new Health Physicists with little practical experience and to those wishing to improve self-assessment, audit, and appraisal processes. Many audits, appraisals, and evaluations have indicated a need for cultural change, increased vigor and example, and more effective oversight by line management. Inadequate work controls are a frequent and recurring problem identified in occurrence reports and accident investigations. Closer study frequently indicates that many line managers are willing to change and want to achieve excellence, but no effective guidance exists that will enable them to understand and implement a modern radiological control program. The manual is now in draft form and includes information that will be of use to line managers dealing with improving radiological performance and the practical aspects of radiological controls implementation. The manual is expected to be completed by the fall of 1993 and to be used in conjunction with a performance-based self-assessment training program at the Oak Ridge National Laboratory

    The human embryo-fetus is highly radiosensitive and must be protected from excessive exposure to ionizing radiation. The maximum permissible dose equivalent for the developing embryo-fetus is set at 0.5 rem per year - the MPD level for members of the general public. Methods by which supervisory personnel can limit the fetal dose incurred by the occupational exposure of the mother are presented. It is recommended that supervisory personnel attempt to limit occupational exposure to the current non-occupational MPD levels for all x-ray technologists, thereby, insuring that the fetal dose limits are not surpassed and providing an added safety factor for personnel by keeping exposures as low as reasonably achievable

    A case of peritoneal malignant mesothelioma in a radiation technologist, who had worked in this field for 34 years, is reported. Histopathologically, a biopsy specimen from the retroperitoneal tumor revealed a biphasic type of malignant mesothelioma. Electron microscopy disclosed that the tumor cells contained prominent microvilli, basal laminae adjacent to the stroma, junctional complexes, desmosomes, tonofilaments, clusters of glycogen granules, well developed rough endoplasmic reticulum (RER), confronting cisternae showing direct continuity with the RER and membrane-bound granules suggestive of secretory activity. No increased amount of asbestos was detected in autopsied lung material or the peritoneal mesothelioma. The estimated cumulative dose of occupational irradiation was calculated to be about 40 to 50 rad at most. Irradiation was discussed in relation to the etiology of the peritoneal mesothelioma.

    To evaluate the self-reported leadership practices of radiology administrators and the demographic characteristics associated with those leadership practices. The effect of these demographic characteristics and leadership practices on job satisfaction also was studied. One-hundred forty-nine American Society of Radiologic Technologists members who indicated they have a position of administrator/manager, chief technologist, or supervisor completed a demographic survey and the Leadership Practices Inventory (LPI) self-survey tool. The LPI divides successful leadership into 5 practices: Challenge the Process, Inspire a Shared Vision, Enable Others to Act, Encourage the Heart, and Model the Way. The categories Challenge the Process and Inspire a Shared Vision had the lowest mean scores and the widest variation. Having had formal leadership training and being older were demographic characteristics associated with higher LPI scores. Having a higher LPI score and having had formal leadership training were associated with higher job satisfaction. Formal leadership training was the only statistically significant variable when using LPI score as the response variable. The results of this study show that radiology administrators would benefit from formal leadership training that focuses on challenging the process and inspiring a shared vision.

    This article is based on the New Horizons lecture delivered at the 2016 Radiological Society of North America Annual Meeting. It addresses looming changes for radiology, many of which stem from the disruptive effects of the Fourth Industrial Revolution. This is an emerging era of unprecedented rapid innovation marked by the integration of diverse disciplines and technologies, including data science, machine learning, and artificial intelligence-technologies that narrow the gap between man and machine. Technologic advances and the convergence of life sciences, physical sciences, and bioengineering are creating extraordinary opportunities in diagnostic radiology, image-guided therapy, targeted radionuclide therapy, and radiology informatics, including radiologic image analysis. This article uses the example of oncology to make the case that, if members in the field of radiology continue to be innovative and continuously reinvent themselves, radiology can play an ever-increasing role in both precision medicine and value-driven health care. © RSNA, 2018.

    Color-blindness is the inability to perceive differences between some color that other people can distinguish. Using a literature search, the results indicate the prevalence of color vision deficiency in the medical profession and its on medical skills. Medical laboratory technicians and technologists employees should also screen for color blindness. This research aimed to study color blindness prevalence among Hospitals' Clinical Laboratories' Employees and Students in Tehran University of Medical Sciences (TUMS). A cross-sectional descriptive and analytical study was conducted among 633 TUMS Clinical Laboratory Sciences' Students and Hospitals' Clinical Laboratories' Employees to detect color-blindness problems by Ishihara Test. The tests were first screened with certain pictures, then compared to the Ishihara criteria to be possible color defective were tested further with other plates to determine color - blindness defects. The data was saved using with SPSS software and analyzed by statistical methods. This is the first study to determine the prevalence of color - blindness in Clinical Laboratory Sciences' Students and Employees. 2.4% of TUMS Medical Laboratory Sciences Students and Hospitals' Clinical Laboratories' Employees are color-blind. There is significant correlation between color-blindness and sex and age. But the results showed that there is not significant correlation between color-blindness defect and exposure to chemical agents, type of job, trauma and surgery history, history of familial defect and race. It would be a wide range of difficulties by color blinded students and employees in their practice of laboratory diagnosis and techniques with a potentially of errors. We suggest color blindness as a medical conditions should restrict employment choices for medical laboratory technicians and technologists job in Iran.

    According to the recent developments in radiological techniques, the role of radiology in the clinical management of patients is ever increasing and in turn, so is the importance of radiology in patient management. Thus far, there have been few open discussions about medical ethics related to radiology in Korea. Hence, concern about medical ethics as an essential field of radiology should be part of an improved resident training program and patient management. The categories of medical ethics related with radiology are ethics in the radiological management of patient, the relationship of radiologists with other medical professionals or companies, the hazard level of radiation for patients and radiologists, quality assurance of image products and modalities, research ethics, and other ethics issues related to teleradiology and fusion imaging. In order to achieve the goal of respectful progress in radiology as well as minimizing any adverse reaction from other medical professions or society, we should establish a strong basis of medical ethics through the continuous concern and self education

  11. Radiological Image Compression

    Science.gov (United States)

    Lo, Shih-Chung Benedict

    The movement toward digital images in radiology presents the problem of how to conveniently and economically store, retrieve, and transmit the volume of digital images. Basic research into image data compression is necessary in order to move from a film-based department to an efficient digital -based department. Digital data compression technology consists of two types of compression technique: error-free and irreversible. Error -free image compression is desired; however, present techniques can only achieve compression ratio of from 1.5:1 to 3:1, depending upon the image characteristics. Irreversible image compression can achieve a much higher compression ratio; however, the image reconstructed from the compressed data shows some difference from the original image. This dissertation studies both error-free and irreversible image compression techniques. In particular, some modified error-free techniques have been tested and the recommended strategies for various radiological images are discussed. A full-frame bit-allocation irreversible compression technique has been derived. A total of 76 images which include CT head and body, and radiographs digitized to 2048 x 2048, 1024 x 1024, and 512 x 512 have been used to test this algorithm. The normalized mean -square-error (NMSE) on the difference image, defined as the difference between the original and the reconstructed image from a given compression ratio, is used as a global measurement on the quality of the reconstructed image. The NMSE's of total of 380 reconstructed and 380 difference images are measured and the results tabulated. Three complex compression methods are also suggested to compress images with special characteristics. Finally, various parameters which would effect the quality of the reconstructed images are discussed. A proposed hardware compression module is given in the last chapter.

  12. Radiological Protection in Medicine

    Valetin, J.

    2011-01-01

    This report was prepared to underpin the Commission's 2007 Recommendations with regard to the medical exposure of patients, including their comforters and carers, and volunteers in biomedical research. It addresses the proper application of the fundamental principles (justification, optimisation of protection, and application of dose limits) of the Commission's 2007 Recommendations to these individuals. With regard to medical exposure of patients, it is not appropriate to apply dose limits or dose constraints, because such limits would often do more harm than good. Often, there are concurrent chronic, severe, or even life-threatening medical conditions that are more critical than the radiation exposure. The emphasis is then on justification of the medical procedures and on the optimisation of radiological protection. In diagnostic and interventional procedures, justification of procedures (for a defined purpose and for an individual patient), and management of the patient dose commensurate with the medical task, are the appropriate mechanisms to avoid unnecessary or unproductive radiation exposure. Equipment features that facilitate patient dose management, and diagnostic reference levels derived at the appropriate national, regional, or local level, are likely to be the most effective approaches. In radiation therapy, the avoidance of accidents is a predominant issue. With regard to comforters and carers, and volunteers in biomedical research, dose constraints are appropriate. Over the last decade, the Commission has published a number of documents that provided detailed advice related to radiological protection and safety in the medical applications of ionising radiation. Each of the publications addressed a specific topic defined by the type of radiation source and the medical discipline in which the source is applied, and was written with the intent of communicating directly with the relevant medical practitioners and supporting medical staff.

    This paper discusses evaluation of normal and diseased endocrine organs that has been facilitated by the development of new radiologic-imaging techniques including nuclear medicine, ultrasound, computed tomography, and magnetic resonance imaging. With improvement in resolution and tissue contrast, abnormalities as small as 5 mm can now be imaged with these modalities. Endocrinologists and clinicians involved in the evaluation and diagnosis of patients with endocrine diseases can be substantially aided by a proper radiologic workup. The authors describe and illustrate various radiologic techniques that are useful for evaluating thyroid and parathyroid derangements

    With the rising incidence of chronic liver disease caused by viral hepatitis, hepatocellular carcinoma is showing a corresponding rise worldwide. Surgery remains the mainstay of treatment, but patients unfit for surgery or liver transplantation form the bulk of those presenting with this disease. Palliative treatments are being used to treat those and radiological modalities form the mainstay of the treatment. Radiology plays a major role in the diagnosis, treatment and follow-up of hepatocellular carcinoma. Current radiological treatment modalities include percutaneous ethanol ablation, radiofrequency ablation and trans-arterial chemoembolization. This update highlights the recent advancements in the field and compares their relative merits and demerits. (author)

    2015-05-01

    This study assesses the prevalence of use of the most commonly used social media sites among private radiology groups (PRGs) and academic radiology departments (ARDs). The 50 largest PRGs and the 50 ARDs with the highest level of funding from the National Institutes of Health were assessed for presence of a radiology-specific social media account on Facebook, Twitter, Instagram, Pinterest, YouTube, and LinkedIn. Measures of organizational activity and end-user activity were collected, including the number of posts and followers, as appropriate; between-group comparisons were performed. PRGs adopted Facebook 12 months earlier (P = .02) and Twitter 18 months earlier (P = .02) than did ARDs. A total of 76% of PRGs maintained ≥1 account on the social media sites included in the study, compared with 28% of ARDs (P Instagram, 2%. The prevalence of radiology-specific social media accounts for ARDs was: Facebook, 18%; LinkedIn, 0%; Twitter, 24%; YouTube, 6%; Pinterest, 0%; and Instagram, 0%. There was no significant difference between ARDs and PRGs in measures of end-user or organizational activity on Facebook or Twitter. Use of social media in health care is emerging as mainstream, with PRGs being early adopters of Facebook and Twitter in comparison with ARDs. Competitive environments and institutional policies may be strong factors that influence how social media is used by radiologists at the group and department levels.

    In September 2000, an expert mission was assigned to Chile, under the regional project named 'International BBS in Medical Practices Radiation Protection and Quality Assurance In Interventional Radiology' (ARCAL XLIX). The objective of the mission was to evaluate the level of radiation protection (RP) and safety in interventional cardiology ( IC ) installations. A team of local cardiologists, medical physicists and technologists was created for this purpose and during one week, several cardiology laboratories were evaluated and some basic quality controls (QC) were carried out. A basic pilot training course in radiation protection was imparted at the Hospital of the University of Chile in Santiago de Chile and some of the key objectives for a future national quality assurance programme were presented during the national congress of IC. In addition, a national survey on radiation protection aspects was circulated and its results evaluated. These activities enabled the local team to become familiar with the methodology of assessment of the level of protection and the organization of a programme, which was illustrated with the examples of similar European programmes. As result of these actions, several proposals were made to both the local authorities and the IAEA. The most important were: a) to initiate a basic QC programme, b) to organize a training in RP for cardiologists in order to formalize their accreditation, c) to improve personal occupational dosimetry, d) to initiate a programme of patient dosimetry, e) to optimize the technical and clinical protocols, f) to create a national registry of incidents with skin injuries.

    We implemented an Image Quality Reporting and Tracking Solution (IQuaRTS), directly linked from the PACS, to improve communication between radiologists and technologists. IQuaRTS launched in May 2015. We compared MRI issues filed in the period before IQuaRTS implementation (May-September 2014) using a manual system with MRI issues filed in the IQuaRTS period (May-September 2015). The unpaired t test was used for analysis. For assessment of overall results in the IQuaRTS period alone, all issues filed across all modalities were included. Summary statistics and charts were generated using Excel and Tableau. For MRI issues, the number of issues filed during the IQuaRTS period was 498 (2.5% of overall MRI examination volume) compared with 78 issues filed during the period before IQuaRTS implementation (0.4% of total examination volume) (p = 0.0001), representing a 625% relative increase. Tickets that documented excellent work were 8%. Other issues included images not pushed to PACS (20%), film library issues (19%), and documentation or labeling (8%). Of the issues filed, 55% were MRI-related and 25% were CT-related. The issues were stratified across six sites within our institution. Staff requiring additional training could be readily identified, and 80% of the issues were resolved within 72 hours. IQuaRTS is a cost-effective online issue reporting tool that enables robust data collection and analytics to be incorporated into quality improvement programs. One limitation of the system is that it must be implemented in an environment where staff are receptive to quality improvement.

    The biopsy of the first tumor-draining lymph node (sentinel node) is bound to become the procedure of choice in regional staging of skin melanoma patients. In our department, we do successively: lymphoscintigraphy; identification of sentinel node by γ probe before surgery; identification during surgery of sentinel node with γ probe. During those different steps, the technologist has an important role. The different steps of the technologist's work are: Preparation of radiopharmaceutical Tc 99m Nanocolloides (Nanocis Cis Bio Int); Control of radio chemical purity(RCP) by thin-layer chromatography (TLC); Programming of acquisition protocol on the γ camera; Acquisition of dynamic and static images; Identification percutaneous of the sentinel node with the γ probe and Co 57 pencil; Processing of scintigraphic images; At least identification with surgeon of the sentinel node. After excision of the lymph node, we have to verify the disappearing of radioactivity. Those steps will be illustrated by different clinical cases. Conclusion: Sentinel node identification is: New useful technique for patient: not very much invasive; screening of patients with high risk factors; great parameters of prognosis; Interest for technologist: narrow collaboration with nuclearist and surgeon; psychological role close to the patient; various competency of technologist; diagnostic and therapeutic participations

    Using the results of a six month survey on the doses received by non-monitored hospital workers from diagnostic nuclear medicine patients (DNMP) in three hospitals and published statistics on Quebec's workers and hospitals, an evaluation of the radiological impact of DNMP has been calculated on the Quebec's population. In 1989, diagnostic nuclear medicine gave an average of 6.4 mSv/act or a total of 2,800 sv-man. The diagnostic nuclear medicine technologists' community received 0.4 Sv-man and the non-monitored hospital workers 1.7 Sv-man from the DNMP in the same year. (author)

  3. Radiological attacks and accidents. Medical consequences

    2007-01-01

    Probability of the occurrence of radiological attacks appears to be elevated after the terrorist attacks against the United States on September 11 in 2001. There are a lot of scenarios of radiological attack: simple radiological device, radiological disperse device (RDD or dirty bomb), attacks against nuclear reactor, improvised nuclear device, and nuclear weapons. Of these, RDD attack is the most probable scenario, because it can be easily made and can generate enormous psychological and economic damages. Radiological incidents are occurring to and fro in the world, including several cases of theft to nuclear facilities and unsuccessful terrorist attacks against them. Recently, a former Russian spy has allegedly been killed using polonium-210. In addition, serious radiological accidents have occurred in Chernobyl, Goiania, and Tokai-mura. Planning, preparation, education, and training exercise appear to be essential factors to cope with radiological attacks and accidents effectively without feeling much anxiety. Triage and psychological first aid are prerequisite to manage and provide effective medial care for mass casualties without inducing panic. (author)

    2012-01-01

    Purpose: A nation-wide evaluation of ionizing radiation exposure of the Romanian population due to the radiological examinations is performed in accordance with European Directive 97/43 EURATOM implemented in national regulations. Method: The study is applied to the collected data from radiological departments from Romanian hospitals during 2010. The radiological examinations were grouped in three categories: conventional diagnostic radiology, interventional radiology and computed tomography. The annual collective dose was determined from the reported data about the mean effective doses and the frequency for each type of radiological examination, in conformity with the national regulations. Regarding the frequency aspects, the results include the age and gender distributions. Major results: More then 6 million radiological examinations were performed in 2010, Romania having a population about of 20.3 million inhabitants. The collective effective dose for 2010 resulted from the study is 152 mSv per 1000 inhabitants. Conclusions: Medical practitioners must select the best medical imaging investigation for each clinical case taking into account the importance of keeping the patient dose as low as possible. Medical physicists should be strongly involved in the establishing of the dosimetry procedures. (author)

    Basic research in interventional radiology, including transcatheter artery perfusion especially, is progressing slowly due to lack of proper method. Microdialysis technique, a kind of accurate sampling technique in vivo, may help to solve the problem. Just as its name implies, microdialysis means tiny dialysis with advantages of authenticity, exactness and less error. Furthermore it has been applied widely and should be received with great attention and popularity. (authors)

  8. Radiological protection report 2016

    International Nuclear Information System (INIS)

    2017-06-01

    In the radiological protection report 2016, the Swiss Federal Nuclear Safety Inspectorate (ENSI) provides an overview of the radiological protection in its area of supervision. Part A of the report deals with protecting the staff of nuclear power plants from the dangers of ionising radiation. It also includes a list of the personal doses accumulated by the staff, broken down using various parameters. Applying the optimisation imperative, it has been proved possible to significantly reduce the annual collective doses in Switzerland's nuclear power plants since they came on stream thanks to major efforts by the operators. In 2016, a total of 6,153 people measured accumulated 2,877 person-mSv. The collective doses have reached a low level corresponding to the radiological condition of the plants and the scope of the work required to be performed in controlled zones (e.g. non-destructive materials testing). ENSI will continue to follow the trend for collective doses and assess the reasons for local variances as well as for measures initiated. The individual doses for people employed in ENSI's area of supervision in 2016 showed a maximum figure of 10 mSv and a mean value of 0.5 mSv which was significantly below the dose limit of 20 mSv for occupational radiation exposure. The discharge of radioactive substances with the exhaust air and waste water from nuclear power plants are dealt with in Part B of the report. In 2016, nuclear power plant operators again met the admissible release limits set by the authorities, in some cases by a considerable margin. The emissions of Swiss nuclear power plants led to a dose of less than 0.01 mSv per year in the direct neighbourhood. A comparison with the average annual radiation dose for the Swiss population of 5.5 mSv shows that the relevant contribution from nuclear power plants lies in the area of one percent of this figure. Effluents from Swiss nuclear power plants were also below the target of 1 GBq per year set by ENSI

    2001-01-01

    The purpose of the International Society of Radiology (ISR), as being the global organization of radiologists, is to promote and help co-ordinate the progress of radiology throughout the world. In this capacity and as a co-operating organization of the IAEA, the ISR has a specific responsibility in the global radiological protection of patients. Globally, there are many users of medical radiation, and radiology may be practised in the most awkward circumstances. The individuals performing X ray studies as well as those interpreting them may be well trained, as in industrialized parts of the world, but also less knowledgeable, as in developing areas. The problems of radiological protection, both of patients and of radiation workers, still exist, and radiation equipment is largely diffused throughout the world. That is why a conference like this is today as important as ever. Radiation protection is achieved through education, on the one hand, and legislation, on the other. Legislation and regulation are the instruments of national authorities. The means of the ISR are education and information. Good radiological practice is something that can be taught. The ISR is doing this mainly through the biannual International Congress of Radiology (ICR), now arranged in an area of radiological need; the three previous ICRs were in China, in India and in South America; the next one is going to be in Mexico in 2002. The goal of the ICR is mainly to be an instructive and educational event, especially designed for the needs of its surrounding region. The ISR is aiming at producing educational material. The International Commission on Radiological Education (ICRE), as part of the ISR, is launching the production of a series of educational booklets, which also include radiation protection. The ICRE is actively involved in shaping and organizing the educational and scientific programme of the ICRs

  10. Radiological terrorism and Australia's response

    International Nuclear Information System (INIS)

    Patterson, D.

    2003-01-01

    A terrorist attack in Australia involving dispersal of radioactive material is different from conventional terrorist attacks involving explosives. The trauma experienced by victims during an explosive incident includes cuts, broken limbs, burns and shock. When an explosive device involving radioactive materials is involved, there are a number of additional characteristics including the contamination of victims and the surrounding area and the potential requirement for ongoing monitoring and decontamination. Response actions may require additional complex emergency response measures including immediate protective actions to protect those potentially exposed to contamination, mass casualty care, and public and mental health. There are concerns that terrorist organizations are showing increasing interest in acquiring radiological material that could be used with explosive. A dirty bomb or technically known as a radiological dispersal device (RDD) is a device designed to spread radioactive contamination over a wide area and pose a health and safety threat to those within the contaminated area. The radioactive material could be in the form of a large chunk of material, fine powder, a liquid mist, or a gas. The material may also be spread in other ways, such as by simply emptying a container over the desired area. As RDD's do not require large amounts of explosives, there is unlikely to be a large numbers of casualties, however the areas contaminated by the radiological material may cause immediate and long term health risks to those exposed. An RDD is a weapon of Mass Disruption rather than destruction. While the likelihood of RDD's being employed by terrorist in Australia is still considered remote, Australia's emergency response organizations are developing plans to ensure a rapid and comprehensive response occurs should such an event occur in this country, The presentation will outline Australia's response arrangements at the local/state level and the type of federal

    With ongoing healthcare payment reforms in the USA, radiology is moving from its current state of a revenue generating department to a new reality of a cost-center. Under bundled payment methods, radiology does not get reimbursed for each and every inpatient procedure, but rather, the hospital gets reimbursed for the entire hospital stay under an applicable diagnosis-related group code. The hospital case mix index (CMI) metric, as defined by the Centers for Medicare and Medicaid Services, has a significant impact on how much hospitals get reimbursed for an inpatient stay. Oftentimes, patients with the highest disease acuity are treated in tertiary care radiology departments. Therefore, the average hospital CMI based on the entire inpatient population may not be adequate to determine department-level resource utilization, such as the number of technologists and nurses, as case length and staffing intensity gets quite high for sicker patients. In this study, we determine CMI for the overall radiology department in a tertiary care setting based on inpatients undergoing radiology procedures. Between April and September 2015, CMI for radiology was 1.93. With an average of 2.81, interventional neuroradiology had the highest CMI out of the ten radiology sections. CMI was consistently higher across seven of the radiology sections than the average hospital CMI of 1.81. Our results suggest that inpatients undergoing radiology procedures were on average more complex in this hospital setting during the time period considered. This finding is relevant for accurate calculation of labor analytics and other predictive resource utilization tools.

    The expectation of the referring physician are key to developing a successful practice in radiology. Structured interviews with 17 clinicians in both community care and academic practice documented that accuracy of the radiologic report was the single most important factor in clinician satisfaction. Data intercorrelation showed that accuracy of report correlated with frequency of referral (r = .49). Overall satisfaction of the referring physician with radiology correlated with accuracy (r = .69), patient satisfaction (r = .36), and efficiency in archiving (r = .42). These data may be weighted by departmental managers to allocate resources for improving referring physician satisfaction

    In addition to being a profession, the practice of radiology is a business, and marketing is an important part of that business. There are many facets to marketing a radiology practice. The authors present a number of ideas on how to go about doing this. Some marketing methods can be directed to both patients and referring physicians. Others should be directed just to patients, while still others should be directed just to referring physicians. Aside from marketing, many of them provide value to both target audiences.

    1998-01-01

    The German Radiological Society, in cooperation with other German professional bodies, set up draft Guidelines for Radiological Interventions and submitted them to the professional community for discussion. The Guidelines are meant to assess the potential of radiological interventions as treatment alternatives to surgery or aggressive therapy such as chemotherapy. In fact, technical practicability on its own is insufficient to warrant intervention. The Guidelines are systematically compiled notions and recommendations whose aim it is to provide support to physicians and patients in choosing suitable medical care provisions (prevention, diagnosis, therapy, aftertreatment) in specific circumstances. A complete Czech translation of the Guidelines is given. (P.A.)

    Due to the rising costs and competitive pressures radiological clinics and practices are now facing, controlling instruments are gaining importance in the optimization of structures and processes of the various diagnostic examinations and interventional procedures. It will be shown how the use of selected controlling instruments can secure and improve the performance of radiological facilities. A definition of the concept of controlling will be provided. It will be shown which controlling instruments can be applied in radiological departments and practices. As an example, two of the controlling instruments, material cost analysis and benchmarking, will be illustrated.

    During the past century, cardiac imaging technologies have revolutionized the diagnosis and treatment of acquired and congenital heart disease. Many important contributions to the field of cardiac imaging were initially reported in Radiology. The field developed from the early stages of cardiac imaging, including the use of coronary x-ray angiography and roentgen kymography, to nowadays the widely used echocardiographic, nuclear medicine, cardiac computed tomographic (CT), and magnetic resonance (MR) applications. It is surprising how many of these techniques were not recognized for their potential during their early inception. Some techniques were described in the literature but required many years to enter the clinical arena and presently continue to expand in terms of clinical application. The application of various CT and MR contrast agents for the diagnosis of myocardial ischemia is a case in point, as the utility of contrast agents continues to expand the noninvasive characterization of myocardium. The history of cardiac imaging has included a continuous process of advances in our understanding of the anatomy and physiology of the cardiovascular system, along with advances in imaging technology that continue to the present day.

    2002-01-01

    Medical imaging processing and analysis methods have significantly improved during recent years and are now being increasingly used in clinical applications. Preprocessing algorithms are used to influence image contrast and noise. Three-dimensional visualization techniques including volume rendering and virtual endoscopy are increasingly available to evaluate sectional imaging data sets. Registration techniques have been developed to merge different examination modalities. Structures of interest can be extracted from the image data sets by various segmentation methods. Segmented structures are used for automated quantification analysis as well as for three-dimensional therapy planning, simulation and intervention guidance, including medical modelling, virtual reality environments, surgical robots and navigation systems. These newly developed methods require specialized skills for the production and postprocessing of radiological imaging data as well as new definitions of the roles of the traditional specialities. The aim of this article is to give an overview of the state-of-the-art of medical imaging processing methods, practical implications for the ragiologist's daily work and future aspects. (orig.) [de

    Rectal stenosis is a common condition caused by a wide variety of diseases, including both intrinsic and extrinsic disorders, as well as both malignant and benign pathologies. Barium enema, CT, and MRI are the primary modalities for the evaluation of the disease, and careful observation of the characteristic radiologic features usually leads to correct diagnosis. However, some of the lesions looks very similar and are difficult to differentiate from each other. The purpose of this study is to review the literature on diseases that cause rectal stenosis, to clarify the characteristics of radiologic features, and to suggest the limitations in differential diagnosis. Deliberate analysis of these imaging features and correlation with clinical manifestations can facilitate a more specific diagnosis. (orig.)

    Nuclear activities in Brazil, and particularly the radiological accident of Goiania, are examined in the light of the environmental and nuclear laws of Brazil and the issue of responsibility. The absence of legislation covering radioactive wastes as well as the restrictions on Brazilian States to issue regulations covering nuclear activities are reviewed. The radiological accident and its consequences, including the protection and compensation of the victims, the responsibility of the shareholders of the Instituto Goiano de Radioterapia, operator of the radioactive source, the provisional storage and the final disposal at Abadia de Goias of the radioactive waste generated by the accident are reviewed. Finally, nuclear responsibility, the inapplicability of the Law 6453/77 which deals with nuclear damages, and the state liability regime are analysed in accordance with the principles of the Brazilian Federal Constitution.

  1. Understanding Mechanisms of Radiological Contamination

    Rick Demmer; John Drake; Ryan James, PhD

    2014-03-01

    Over the last 50 years, the study of radiological contamination and decontamination has expanded significantly. This paper addresses the mechanisms of radiological contamination that have been reported and then discusses which methods have recently been used during performance testing of several different decontamination technologies. About twenty years ago the Idaho Nuclear Technology Engineering Center (INTEC) at the INL began a search for decontamination processes which could minimize secondary waste. In order to test the effectiveness of these decontamination technologies, a new simulated contamination, termed SIMCON, was developed. SIMCON was designed to replicate the types of contamination found on stainless steel, spent fuel processing equipment. Ten years later, the INL began research into methods for simulating urban contamination resulting from a radiological dispersal device (RDD). This work was sponsored by the Defense Advanced Research Projects Agency (DARPA) and included the initial development an aqueous application of contaminant to substrate. Since 2007, research sponsored by the US Environmental Protection Agency (EPA) has advanced that effort and led to the development of a contamination method that simulates particulate fallout from an Improvised Nuclear Device (IND). The IND method diverges from previous efforts to create tenacious contamination by simulating a reproducible “loose” contamination. Examining these different types of contamination (and subsequent decontamination processes), which have included several different radionuclides and substrates, sheds light on contamination processes that occur throughout the nuclear industry and in the urban environment.

    A radiological survey of the former Middlesex Sampling Plant, Middlesex, New Jersey, has been completed. The surveyed property served as a uranium ore sampling plant during the 1940's and early 1950's. It was released for unrestricted use in 1967 following a radiological survey by the Atomic Energy Commission and is now a reserve training center for the U. S. Marine Sixth Motor Transport Battalion. The present survey was undertaken to determine whether the existing radiological status of the property is consistent with current health standards and radiation protection practices. The radiological survey included measurement of residual alpha, beta, and gamma contamination levels, radon and radon daughter concentrations in buildings, external gamma radiation levels on the site and on adjacent property, and radium concentrations in soil on the site and on adjacent property

    The use of computers is increasing in every field of medicine, especially radiology. Filmless radiology departments, speech recognition software, electronic request forms and teleradiology are some of the recent developments that have substantially increased the amount of time a radiologist spends in front of a computer monitor. Computers are also needed for searching literature on the internet, communicating via e-mails, and preparing for lectures and presentations. It is well known that regular computer users can suffer musculoskeletal injuries due to repetitive stress. The role of ergonomics in radiology is to ensure that working conditions are optimized in order to avoid injury and fatigue. Adequate workplace ergonomics can go a long way in increasing productivity, efficiency, and job satisfaction. We review the current literature pertaining to the role of ergonomics in modern-day radiology especially with the development of picture archiving and communication systems (PACS) workstations.

    The rapid pace of technologic advancement and increasing expectations for patient- and family-friendly environments make it common for radiology leaders to be involved in imaging remodel and construction projects. Most radiologists and business directors lack formal training in architectural and construction processes but are expected to play significant and often leading roles in all phases of an imaging construction project. Avoidable mistakes can result in significant increased costs and scheduling delays; knowledgeable participation and communication can result in a final product that enhances staff workflow and morale and improves patient care and experience. This article presents practical guidelines for preparing for and leading a new imaging architectural and construction project. We share principles derived from the radiology and nonradiology literature and our own experience over the past decade completely remodeling a large pediatric radiology department and building a full-service outpatient imaging center.

    Objective: The aim of this research was to explore the perceived value of clinical clerkships in the radiology curriculum as well as the impact of radiology clerkship on students' beliefs about the profession of radiology as a whole and as a career. Methods: This study is a sequel to a previous survey in which student perceptions about radiology curriculum components were investigated. The present study focuses on a further analysis of a subsection in this study, based on 14 statements about radiology clerkship and two statements about radiology as a career. Results: Perceived usefulness of the aspects of radiology clerkship as 'radiology examination', 'skills development' and 'diagnosis focus' were awarded the highest scores. The predict value of the subscale 'radiology examination' on the level of performance was very high (adjusted R 2 = 0.19, p < .001). Conclusion: Students expressed highly favorable evaluation of clerkship as a learning environment to learn to order and to interpret imaging studies as well as an unique possibility to attend various radiological examinations and to access to specific radiology software systems, as well as to get a better view on radiology and to improve image interpretation skills. This positive attitude towards clerkship is closely tied to students' beliefs about the profession of radiology as a whole. These aspects of dedicated radiology clerkship are crucial for effective and high-quality education as well as for the choice of radiology as a career.

    Emergencies in radiology are infrequent but potentially lethal. Australian and New Zealand radiologists are advised to undergo resuscitation training at least every three years; however, little is known about their experience and confidence in managing common emergencies relevant to their clinical practice. This paper describes the current experience and confidence of radiologists and radiology trainees in Australia and New Zealand in the management of common medical emergencies. A cross-sectional online survey of trainees and fellows of the Royal Australian and New Zealand College of Radiology collected data on training and learning preferences relating to resuscitation and life-support skills, access to emergency medical care, and knowledge, confidence and ability in managing a variety of medical emergencies. There were 602 responses to the survey (response rate 23.4%). The majority of respondents were interested in learning more about the management of contrast reactions, cardiac arrest, ischaemic chest pain and basic life support. Self-rated knowledge, confidence and ability were higher in respondents who had completed life-support training within the previous three years. In this group, however, more than 40% rated their ability at managing contrast reactions as poor or fair, while more than 60% rated their ability as poor or fair for management of cardiac arrest, basic life support, advanced life support and dosing of adrenaline. Preferred resuscitation training modalities included simulation, small-group tutorials and workshops. Self-reported level of skill and expertise in the management of potential emergencies in radiology is suboptimal among a large number of respondents. Consideration should be given to addressing this by improving access to specific training.

    The purpose of this design guide is to provide radiological safety requirements, standards, and information necessary for designing facilities that will operate without unacceptable risk to personnel, the public, or the environment as required by the US Department of Energy (DOE). This design guide, together with WHC-CM-4-29, Nuclear Criticality Safety, WHC-CM-4-46, Nonreactor Facility Safety Analysis, and WHC-CM-7-5, Environmental Compliance, covers the radiation safety design requirements at Westinghouse Hanford Company (WHC). This design guide applies to the design of all new facilities. The WHC organization with line responsibility for design shall determine to what extent this design guide shall apply to the modifications to existing facilities. In making this determination, consideration shall include a cost versus benefit study. Specifically, facilities that store, handle, or process radioactive materials will be covered. This design guide replaces WHC-CM-4-9 and is designated a living document. This design guide is intended for design purposes only. Design criteria are different from operational criteria and often more stringent. Criteria that might be acceptable for operations might not be adequate for design

    To evaluate the CT findings of bronchial anthracofibrosis. Fourteen patients with bronchoscopically confirmed anthracofibrosis were involved in this study. CT findings (n=3D12) were retrospectively analysed; the pattern, distri-bution and extent of bronchial and parenchymal abnormalities and additional findings such as mediastinal lymphadenopathy and pleural effusion were assessed. Age, sex, and occupational and disease history were history were also reviewed. Patients were aged between 63 and 95 (mean, 71.3) years, and ten were female. Only one patient had an occupational history, but four had a history of pulmonary tuberculosis. Frequent radiologic findings were bronchial wall thickening(n=3D6), atelectasis(n=3D8), mediastinal lymphad-enopathy(n=3D7) and mass(n=3D4). Other accompanying findings were bronchial wall calcification(n=3D3), consolidation(n=3D2) and pleural effusion(n=3D2). Right upper (n=3D7) and right middle lobe(n=3D7) were the most commonly involved sites, and multifocal involvement (n=3D7) was frequent. Bronchial wall thickening, atelectasis and mediastinal lymphadenopathy were characteristic CT findings of anthracofibrosis. When such findings are noted in older or aged female patients, anthracofibrosis should be included in the differential diagnosis

    Epilepsy is a heterogenous group of disorders with multiple causes. Clinical management of epilepsy patients requires knowledge of seizure syndromes, causes, and imaging features. The aim of radiological investigations is to recognize the underlying cause of epilepsy. The main indications for neuroimaging studies are partial and secondarily generalized seizures, patients with neurological signs and intractable seizures, and patients with focal signs on EEG. Partial seizures of any type are more likely to be associated with a focus that may be identified on neuroimaging. MRI is the method of choice for evaluating structural abnormalities of the brain. High resolution MRI and dedicated imaging technique are needed for detection of subtle pathological changes as cortical dysplasias and temporal medial sclerosis. Other lesions that may be detected include neoplasms, vascular malformations, destructive lesions following brain injury, stroke, infection, etc. CT continues to be the technique for the investigation of patients with seizures under certain conditions. New techniques such as functional MRI, MR spectroscopy, SPECT, receptor PET and magnetic source imaging are becoming clinical tools for improving diagnosis [et

    Clinical laboratories in university hospitals should be operated with a good balance of medical practice, education, research, and management. The role of a clinical laboratory is to promptly provide highly reliable laboratory data to satisfy the needs of clinicians involved in medical practice and health maintenance of patients. Improvement and maintenance of the quality of the laboratory staff and environment are essential to achieve this goal. In order to implement these requirements efficiently, an appropriate quality management system should be introduced and established, and evaluated objectively by a third party (e.g. by obtaining ISO 15189 certification). ISO 15189 is an international standard regarding the quality and competence of clinical laboratories, and specifies a review of the efficient operational system and technical requirements such as competence in implementing practical tests and calibration. This means the results of laboratory tests reported by accredited laboratories withstand any international evaluation, which is very important to assure the future importance of the existence and management of clinical laboratories as well as internationalization of medical practice. "Education" and "research" have important implications in addition to "medical practice" and "management", as the roles that clinical laboratories should play in university hospitals. University hospital laboratories should be operated by keeping these four factors in good balance. Why are "education" and "research" required in addition to "medical practice" services? If individual clinical laboratory technologists can provide an appropriate response to this question, the importance of the existence of clinical laboratories would be reinforced, without being compromised.

    Full Text Available The food & drink (F&D sector in Europe ranks low in innovation and the European F&D industry has been losing importance in the global market. The food professionals, i.e., food scientists and technologists (FSTs, may not be meeting the varied demands of the sector. Here, we identify education, experience and skills of current FSTs and compare  geographic regions and employment areas. Between 2009 and 2012, 287 questionnaires representing over 4000 FSTs were collected from employers in 16 countries. Analyses showed that more than 80% of FSTs have a university degree; but only in Industry in the Central European region are most degrees in food science/technology. More than half of FSTs, and almost 60% in the South, have less than 10 years’ experience. The most common FST job title is Quality Manager, but with several variations based on region and employment area. Among skills, the most common is Communicating; found in over 90% of FSTs in all regions and employment areas. Food Safety is the most common of the food sector-specific skills, present in more than 75% of FSTs, yet there are differences in food sector skills based on employment area. Overall, these data suggest similarities among currently employed food professionals throughout Europe; they are young and highly educated, but also differences, especially in their food sector-specific skills. An understanding of the current FST should contribute to the improvement of FST training and thus benefit the European food sector.

    Objective: To explore the radiological features of hypophosphatasia. Methods: Five cases of hypophosphatasia were definitely diagnosed, which included 3 males and 2 females aged from 5 months to 23 years. The laboratory assays were analyzed, radiological appearances of bone were determined and differential diagnoses were made. Results: The alkaline phosphatase in blood serum of five patients decreased, which were 8, 20, 13, 21, and 18 U/L respectively. Phosphoethanolamine increased in blood serum of the five patients, which were 16.5, 13.5, 21.6, 18.7, and 28.9 μmol/L respectively. Phosphoethanolamine also increased in urine,which were 2350, 9120, 3520, 5280, and 1820 μmol/L respectively. Calcium in blood serum increased, which were 4.2, 5.6, 4.9, 6.1, and 3.5 mmol/L respectively. X-ray images displayed that the density of bone decreased in 5 cases, the metaphyses exhibited widening and cupping in 4 cases, the provisional calcification zone of the metaphysis became thinning or disappearing in 4 cases, long bone bended in 4 cases and pathologically fractured in 1 case. Conclusion: Hypophosphatasia can be indicated by its relatively special radiological appearance, and it can be diagnosed and differentiated from rickets, osteomalacia and osteogenesis imperfect by the laboratory examination combined with its clinical presentation.

  2. Report writing in skeletal radiology

    International Nuclear Information System (INIS)

    Rowe, L.J.; Yochum, T.R.

    1987-01-01

    The formulation of reports in clinical practice is a standard method of documentation of a patient's history, examination findings, therapeutic regime, and prognosis, as well as other important features. In the practice of producing and interpreting diagnostic radiographs, report writing also serves a number of important roles, which include providing an accurate means of recording findings in instances of 1) medicolegal circumstances; 2) a standard for comparison with previous or later examinations; 3) a permanent record if the radiographs are lost or not immediately available for perusal; 4) communication with other practitioners and health professionals; and 5) expediating the treatment regime by providing a resume of important indications and contraindictions for therapy. In the radiological literature there is a distinct lack of material on report writing and very little as to what would be considered a standard style. Consequently, radiological reporting has increasingly become a subjective, personalized procedure, with each individual modifying the report according to previous training, experience, and needs. It is the purpose of this chapter to provide basic guidelines on the mechanisms of formulating adequate standardized reports in radiological examinations of the skeletal system

    A brief radiological safety and risk assessment of a nuclear power generation center with an adjacent on-site waste disposal facility at a specific site in the State of Utah is presented. The assessment was conducted to assist in determining the feasibility and practicality of developing a nuclear energy center (NEC) in Utah consisting of nine 1250 MWe nuclear pressurized water reactor (PWR) electrical generating units arranged in 3 clusters of 3 units each known as triads. The site selected for this conceptual study is in the Horse Bench area about 15 miles directly south of the town of Green River, Utah. The radiological issues included direct radiation exposures to on-site workers and the off-site population, release of radioactive material, and effects of these releases for both normal operations and accidental occurrences. The basic finding of this study is that the concept of an NEC in the Green River area, specifically at the Horse Bench site, is radiologically feasible

    Pulmonary tuberculosis (TB) is a common worldwide lung infection. The radiological features show considerable variation, but in most cases they are characteristic enough to suggest the diagnosis. Classically, tuberculosis is divided into primary, common in childhood, and postprimary, usually presenting in adults. The most characteristic radiological feature in primary tuberculosis is lymphadenopathy. On enhanced CT, hilar and mediastinal nodes with a central hypodense area suggest the diagnosis. Cavitation is the hallmark of postprimary tuberculosis and appears in around half of patients. Patchy, poorly defined consolidation in the apical and posterior segments of the upper lobes, and in the superior segment of the lower lobe is also commonly observed. Several complications are associated with tuberculous infection, such as hematogenous dissemination (miliary tuberculosis) or extension to the pleura, resulting in pleural effusion. Late complications of tuberculosis comprise a heterogeneous group of processes including tuberculoma, bronchial stenosis bronchiectasis, broncholithiasis, aspergilloma, bronchoesophageal fistula and fibrosing mediastinitis. Radiology provides essential information for the management and follow up of these patients and is extremely valuable for monitoring complications.

    Diagnostic errors are important in all branches of medicine because they are an indication of poor patient care. Since the early 1970s, physicians have been subjected to an increasing number of medical malpractice claims. Radiology is one of the specialties most liable to claims of medical negligence. Most often, a plaintiff's complaint against a radiologist will focus on a failure to diagnose. The etiology of radiological error is multi-factorial. Errors fall into recurrent patterns. Errors arise from poor technique, failures of perception, lack of knowledge and misjudgments. The work of diagnostic radiology consists of the complete detection of all abnormalities in an imaging examination and their accurate diagnosis. Every radiologist should understand the sources of error in diagnostic radiology as well as the elements of negligence that form the basis of malpractice litigation. Error traps need to be uncovered and highlighted, in order to prevent repetition of the same mistakes. This article focuses on the spectrum of diagnostic errors in radiology, including a classification of the errors, and stresses the malpractice issues in mammography, chest radiology and obstetric sonography. Missed fractures in emergency and communication issues between radiologists and physicians are also discussed.

  7. Evolution of the system of radiological protection

    International Nuclear Information System (INIS)

    2005-11-01

    One of the main challenges facing radiological protection experts is how to integrate radiological protection within modern concepts of and approaches to risk governance. It is within this context that the International Commission on Radiological Protection (ICRP) decided to develop new general recommendations to replace its Publication 60 recommendations of 1990. In the process of developing these new recommendations, the views of the ICRP have evolved significantly, largely due to stakeholder involvement that has been actively solicited by the ICRP. In this regard, it was upheld during the First Asian Regional Conference organised by the NEA in October 2002 that the implementation of the new system must allow for regional, societal and cultural differences. In order to ensure appropriate consideration of these differences, the NEA organised the Second Asian Regional Conference on the Evolution of the System of Radiological Protection. Held in Tokyo on 28-29 July 2004, the conference included presentations by the ICRP Chair as well as by radiological experts from Australia, China, Japan and Korea. Within their specific cultural and socio-political milieu, Asia-Pacific and western ways of thought on how to improve the current system of radiological protection were presented and discussed. These ways of thinking, along with a summary of the conference results, are described in these proceedings. (author)

    The International Commission on Radiological Protection and the international organizations that co-sponsored the International Basic Safety Standards for the Protection against Ionization Radiation and for the Safety of Radiation Sources (BSS) - among them PAHO and WHO - recommended the use of investigation levels to provide guidance for medical exposures. In this work, entrance surface doses for several common diagnostic radiology procedure have been determined from exposure rate measurements and patient technique factors in seven 'World Health Imaging System - Radiography' (WHIS-RAD) units, installed in public health services facilities of the Republic of Haiti. The results show the entrance surface doses below the guidance levels published in the BSS. Concomitant image quality measurements performed, however, indicate serious artifacts in the film processing, calling for the need of additional training of the technologists. (author)

    Full Text Available It has been my good fortune to live and practice radiology during a long period of momentous change – to see the transformation of the discipline from a supportive service into a mainstream, essential branch of clinical medicine. I remember wearing red goggles to adapt my vision before performing fluoroscopy; observing the horrible, now thankfully obsolete, practice of ventriculography, which was considered advanced neuroradiology; and performing other, now rarely prescribed procedures, such as double-contrast barium enemas and intravenous pyelography. Witnessing the beginnings of interventional radiology, I suggested its name in an editorial. I also had the good fortune to see the introduction of computed tomography (CT and a technology first known as nuclear magnetic resonance imaging. Together with fellow members of a committee of the American College of Radiology and editors of prestigious radiological journals, I took part in changing the name of the latter modality to MRI, freeing it from threatening implications. Looking back on these experiences, one lesson stands out above all: Innovation and transformation never cease. Looking forward, it is clear that radiology, along with the rest of medicine, is now undergoing further momentous changes that will affect the future of all those already practicing as well as those yet to start their careers.

    Complete text of publication follows. Background and purpose: Radiology department that provides images with proper quality plays a vital role in diagnosis of diseases. Good image is obtained by proper technical criteria and correct Positioning. Personnel practice of radiology department has a principal role on radiographs quality. This study was carried out to determine the radiology department personnel practice in university hospitals. Method and Material: Data collection was made using an observational check list. Its validity and reliability was determined previously. The sample size of which was thirty-nine persons. 29 items of practice related to technical and protect ional aspects at three working shifts were observed and recorded separately. Results: Results showed that most of the personnel were female (61.5%), over 40 years old (59%) and technicians (53.8%). On the whole, personnel's score percentages in technical field on three shifts of morning evening and night were 47.5%, 46.2%, and 45.9%, respectively which were less than them in protect ional field (60.3%, 56A% and 55.8%, respectively). Comparison of technical protection and total scores related to individual variables showed significant difference only in organizational grades (p<0.0001, p<0.05, p<0.0001, respectively) Le. The mean scores of radiological technologists holding BSc and associate degrees were more than those of technologists not holding university degrees. Conclusion: The quality of the personnel practice is not desirable; therefore continuing education programmers are needed for personnel. Protection against radiation exposure, availability of equipment and continuous evaluation of use of equipment can be effective in dose reduction in patients.

    This book is divided into three parts: The first part - 'Technology and normal findings' - explains current radiological diagnostic methods. The indications for particular examinations are given, with the techniques and possible errors. The second part of the book - 'Diseases of the lung' - gives a systematic description of basic knowledge needed for diagnosis. Each chapter begins with a definition of the disease and a discussion of the diagnostic information that can be expected from the various radiological methods. This is followed by the pathological morphology and pathological physiology and the clinical symptoms. The third part of the book - 'Radiological signs and differential diagnosis' - deals with image patterns, such as segmental opacities, calcification, localized hyperlucency, etc. It begins where the diagnostician must begin - immediate confrontation with the radiograph, analysis of the details, recognition of structures and understanding the image.

    The purpose of this study was to clarify actual conditions and problems in medical information education and to propose the educational concept to be adopted in medical information. A questionnaire survey was carried out by the anonymous method in June 2008. The survey was intended for 40 radiological technology schools. The questionnaire items were as follows: (1) educational environment in medical information education, (2) content of a lecture in medical information, (3) problems in medical information education. The response rate was 55.0% (22 schools). Half of the responding schools had a laboratory on medical information. Seventeen schools had a medical information education facility, and out of them, approximately 50% had an educational medical information system. The main problems of the medical information education were as follows: (a) motivation of the students is low, (b) the educational coverage and level for medical information are uncertain, (c) there are not an appropriate textbook and educational guidance. In conclusion, these findings suggest that it is necessary to have a vision of medical information education in the education of radiological technologists.

    As interventional radiology (IVR) has become widespread recently, skin injury caused by exposure to radiation have been reported in academic meetings, and are a major concern in academic circles. In 1986, The Japanese Society of Circulation Imaging Technology (CITEC)'s organized a group to engage in an actual condition survey on cineangiography. We have studied exposed doses to patients in the event of cardiac catheterization using ancate data available in Japan and made efforts to spread methods of reducing exposure doses through academic meetings and medical journal. In 1998, we set up the Radiation Exposure Control Committee. The committee's objectives were to reduce exposure doses to patients and operators during cardiovascular examinations, and establish concrete of technical methods and protection guidelines for exposed dose reduction. We have studied presentations at academic meetings and study meetings, etc., and classified the results into the following 5 categories: methods of reducing radiation by X-ray equipment, methods of reducing exposure using X-ray protection devices, exposure dosimetry, clinical cases of radiation exposure, and QC, QA. The committee issued a textbook based on the reports and have educated, guided and enlightened radiological technologists, nurses and ME by holding the 'Seminar for reduction technique of radiation exposure in circulator organs.'

    The biological effects of radiation and potential risks therefrom far exceeds the knowledge of any other hazardous agent, whether in the industrial field, or in the general environment affecting members of the public. The International Commission on Radiological Protection (ICRP) has been playing a pioneering role for decades in this direction. The extensive database that has been established over the decades by the ICRP, the methodologies, techniques and the organizational structures that have been developed to control radiation hazards, and, above all, the philosophy of risk evaluation and management that has been evolved by ICRP, would serve as valuable guides not only to those concerned with radiological protection but to scientist, technologist and administrators involved in all facets of occupational and industrial safety, as well as those concerned with environmental protection. From 1959 to the end of 1993 ICRP has brought out 64 publications running to around 9000 pages. It is important that everyone connected with the uses of ionizing radiations should be familiar with at least the basic features of the thinking of ICRP as embodied in these publications. The present handbook attempts to give in a concise, consolidated and codified form the salient features of all the relevant information contained in the voluminous ICRP publications. The material has been presented in 7 parts, each dealing with one major aspect of the recommendations, and summarizing the various publications connected with it.

    The purpose of this study was to clarify actual conditions and problems in medical information education and to propose the educational concept to be adopted in medical information. A questionnaire survey was carried out by the anonymous method in June 2008. The survey was intended for 40 radiological technology schools. The questionnaire items were as follows: educational environment in medical information education, content of a lecture in medical information, problems in medical information education. The response rate was 55.0% (22 schools). Half of the responding schools had a laboratory on medical information. Seventeen schools had a medical information education facility, and out of them, approximately 50% had an educational medical information system. The main problems of the medical information education were as follows: motivation of the students is low, the educational coverage and level for medical information are uncertain, there are not an appropriate textbook and educational guidance. In conclusion, these findings suggest that it is necessary to have a vision of medical information education in the education of radiological technologists. (author)

  1. Radiological incidents in radiotherapy

    2008-01-01

    In many countries a reporting system of radiological incidents to national regulatory body exists and providers of radiotherapy treatment are obliged to report all major and/or in some countries all incidents occurring in institution. State Office for Nuclear Safety (SONS) is providing a systematic guidance for radiotherapy departments from 1997 by requiring inclusion of radiation safety problems into Quality assurance manual, which is the basic document for obtaining a license of SONS for handling with sources of ionizing radiation. For that purpose SONS also issued the recommendation 'Introduction of QA system for important sources in radiotherapy-radiological incidents' in which the radiological incidents are defined and the basic guidance for their classification (category A, B, C, D), investigation and reporting are given. At regular periods the SONS in co-operation with radiotherapy centers is making a survey of all radiological incidents occurring in institutions and it is presenting obtained information in synoptic communication (2003 Motolske dny, 2005 Novy Jicin). This presentation is another summary report of radiological incidents that occurred in our radiotherapy institutions during last 3 years. Emphasis is given not only to survey and statistics, but also to analysis of reasons of the radiological incidents and to their detection and prevention. Analyses of incidents in radiotherapy have led to a much broader understanding of incident causation. Information about the error should be shared as early as possible during or after investigation by all radiotherapy centers. Learning from incidents, errors and near misses should be a part of improvement of the QA system in institutions. Generally, it is recommended that all radiotherapy facilities should participate in the reporting, analyzing and learning system to facilitate the dissemination of knowledge throughout the whole country to prevent errors in radiotherapy.(authors)

  2. Radiology's value chain.

    Science.gov (United States)

    Enzmann, Dieter R

    2012-04-01

    A diagnostic radiology value chain is constructed to define its main components, all of which are vulnerable to change, because digitization has caused disaggregation of the chain. Some components afford opportunities to improve productivity, some add value, while some face outsourcing to lower labor cost and to information technology substitutes, raising commoditization risks. Digital image information, because it can be competitive at smaller economies of scale, allows faster, differential rates of technological innovation of components, initiating a centralization-to-decentralization technology trend. Digitization, having triggered disaggregation of radiology's professional service model, may soon usher in an information business model. This means moving from a mind-set of "reading images" to an orientation of creating and organizing information for greater accuracy, faster speed, and lower cost in medical decision making. Information businesses view value chain investments differently than do small professional services. In the former model, producing a better business product will extend image interpretation beyond a radiologist's personal fund of knowledge to encompass expanding external imaging databases. A follow-on expansion with integration of image and molecular information into a report will offer new value in medical decision making. Improved interpretation plus new integration will enrich and diversify radiology's key service products, the report and consultation. A more robust, information-rich report derived from a "systems" and "computational" radiology approach will be facilitated by a transition from a professional service to an information business. Under health care reform, radiology will transition its emphasis from volume to greater value. Radiology's future brightens with the adoption of a philosophy of offering information rather than "reads" for decision making. Staunchly defending the status quo via turf wars is unlikely to constitute a

    2013-01-01

    ICRP has provided an updated overview of radiation protection principles in pediatric radiology. The authors recommend that staff, radiologists, medical physicists and vendors involved in pediatric radiology read this document. For conventional radiography, the report gives advice on patient positioning, immobilization, shielding and appropriate exposure conditions. It describes extensively the use of pulsed fluoroscopy, the importance of limiting fluoroscopy time, and how shielding and geometry must be used to avoid unnecessary radiation to the patient and operator. Furthermore, the use of fluoroscopy in interventional procedures with emphasis on dose reduction to patients and staff is discussed in light of the increasing frequency, complexity and length ofthe procedures. CT is the main reason that medical imaging in several developed countries is the highest annual per capita effective radiation dose from man-made sources. The ICRP report gives extensive descriptions of how CT protocols can be optimized to minimize radiation exposure in pediatric patients. The importance of balancing image quality with acceptable noise in pediatric imaging and the controversies regarding the use of protective shielding in CT are also discussed.

    1992-01-01

    An important aspect of DOE safety analyses is estimating potential accident risk. The estimates are used to: determine if additional controls are needed, identify Safety Class Items, and demonstrate adequate risk reduction. Thus, guidelines are needed to measure comparative risks. The Westinghouse M ampersand O Nuclear Facility Safety Committee and the Safety Envelope Working Group have developed radiological risk guidelines for comparing the risks from individual accident analyses. These guidelines were prepared under contract with the US Department of Energy. These guidelines are based on historical DOE guidelines and current requirements, and satisfy DOE and technical community proposals. for goals that demonstrate acceptable risk. The guidelines consist of a frequency versus consequence curve for credible accidents. Offsite and onsite guidelines are presented. The offsite risk acceptance guidelines are presented in Figure 1. The guidelines are nearly isorisk for anticipated events where impacts are chronic, and provide additional reduction for unlikely events where impacts may be acute and risk uncertainties may be significant. The guidelines are applied to individual release accident scenarios where a discrete frequency and consequence has been estimated. The guideline curves are not to be used for total risk assessments. Common cause events are taken into consideration only for an individual facility. Frequencies outside the guideline range are considered to be local site option (analyst judgement) as far as assessments of risk acceptance are concerned. If the curve is exceeded, then options include either a more detailed analysis or imposing additional preventive or mitigative features. Another presentation discusses implementation in detail. Additional work is needed to provide risk comparison guidelines for releases from multiple facilities and for toxic releases

  2. Establish radiation protection programme for diagnostic radiology

    Mammography is an effective method used for breast diagnostics and screening. The aim of this project is to review the literature on how to establish radiation protection programme for mammography in order to protect the patients, the occupationally exposed workers and the members of the public from harmful effects of ionizing radiation. It reviews some of the trends in mammography doses and dosimetric principles such as average glandular dose in the glandular tissue which is used for description of radiation risk, also the factors affecting patient doses are discussed. However, the average glandular dose should not be used directly to estimate the radiation risk from mammography. Risk is calculated under certain assumptions from determined entrance surface air kerma. Given the increase in population dose, emphasis is placed on the justification and optimization of the mammographic procedures. Protection is optimized by the radiation dose being appropriate with the purpose of the mammographic examination. The need to establish diagnostic reference levels as an optimization is also discussed. In order to obtain high quality mammograms at low dose to the breast, it is necessary to use the correct equipment and perform periodic quality control tests on mammography equipment. It is noted that in order to achieve the goal of this project, the application of radiation protection should begin at the time of requesting for mammography examination, positioning of the patient, irradiation, image processing and interpretation of mammogram. It is recommended that close cooperation between radiology technologists, radiologist, medical physicists, regulatory authority and other support workers be required and established to obtain a consistent and effective level of radiation protection in a mammography facility.

    Radiological controls are required by law in the design of commercial nuclear power reactor facilities. These controls can be relatively minor or significant, relative to cost. To ensure that radiological controls are designed into a project, the health physicist (radiological engineer) must be involved from the beginning. This is especially true regarding keeping costs down. For every radiological engineer at a nuclear power plant there must be fifty engineers of other disciplines. The radiological engineer cannot be an expert on every discipline of engineering. However, he must be knowledgeable to the degree of how a design will impact the facility from a radiological perspective. This paper will address how to effectively perform radiological analyses with the goal of radiological controls integrated into the design package.

    Over the last several years, the concept and methodology of evidence-based medicine (EBM) have received significant attention in the scientific community. However, compared to therapeutic medical disciplines, EBM-based radiological publications are still underrepresented. This article summarizes the principles of EBM and discusses the possibilities of their application in radiology. The presented topics include the critical appraisal of studies on the basis on EBM principles, the explanation of EBM-relevant statistical outcome parameters (e.g., ''likelihood ratio'' for diagnostic and ''number needed to treat'' for interventional procedures), as well as the problems facing evidence-based radiology. Evidence-based evaluation of radiological procedures does not only address aspects of cost-effectiveness, but is also particularly helpful in identifying patient-specific usefulness. Therefore it should become an integral part of radiologist training. (orig.)

  18. Medical radiology terminology

    International Nuclear Information System (INIS)

    1986-01-01

    Standardization achievements in the field of radiology induced the IEC to compile the terminology used in its safety and application standards and present it in publication 788 (1984 issue), entitled 'Medical radiology terminology'. The objective pursued is to foster the use of standard terminology in the radiology standards. The value of publication 788 lies in the fact that it presents definitions of terms used in the French and English versions of IEC standards in the field of radiology, and thus facilitates adequate translation of these terms into other languages. In the glossary in hand, German-language definitions have been adopted from the DIN standards in cases where the French or English versions of definitions are identical with the German wording or meaning. The numbers of DIN standards or sections are then given without brackets, ahead of the text of the definition. In cases where correspondance of the various texts is not so good, or reference should be made to a term in a DIN standard, the numbers are given in brackets. (orig./HP) [de

  3. Cardiovascular and interventional radiology

    International Nuclear Information System (INIS)

    White, R.I. Jr.

    1985-01-01

    A symposium of eight short but complete papers giving an overview of interventional radiology is presented. Organized by Dr. William Casarella, this symposium is certainly the most current review of the subject available. This year's cardiovascular section is again heavily weighted toward interventional radiology. Abrams and Doubilet's article on the underutilization of angioplasty is important because it describes the cost effectiveness of this method. Most health planners, right or wrong, have complained about overutilization of diagnostic radiology procedures. In general, the opposite is true for interventional procedures - they are underutilized. If the authors draw the attention of their hospital administrators to these approaches and also produce the data on long-term follow-up for our medical colleagues, interventional radiology may realize its full potential. Articles on cardiac magnetic resonance imaging are beginning to appear and this technique seems to have great potential. An important article, which is the first prospective study comparing lung scintigraphy and pulmonary angiography in the diagnosis of pulmonary embolism, supports the increased use of pulmonary angiography. Finally, an article on complications of percutaneous biliary drainage provokes some discussion of its value for routine preoperative use

    Magnavita, N; Bergamaschi, A

    2009-10-01

    One of the causes of the increasing request for radiological examinations occurring in all economically developed countries is the active role played by the patient-consumer. Consumerism places the radiologist in an ethical dilemma, between the principle of autonomy on the one hand and the ethical principles of beneficence, nonmaleficence and justice on the other. The choice made by radiologists in moral dilemmas is inspired by an adherence to moral principles, which in Italy and elsewhere refer to the Judaeo-Christian tradition or to neo-Darwinian relativism. Whatever the choice, the radiologist is bound to adhere to that choice and to provide the patient with all the relevant information regarding his or her state of health.

  13. Lessons learned in radiology

    International Nuclear Information System (INIS)

    Goodenough, D.J.

    2001-01-01

    The paper reviews aspects of the history of radiology with the goal of identifying lessons learned, particularly in the area of radiological protection of the patient in diagnostic and interventional radiology, nuclear medicine and radiotherapy. It is pointed out that since the days of Roentgen there has been a need not only to control and quantify the amount of radiation reaching the patient but also to optimize the imaging process to offer the greatest diagnostic benefit within allowable levels of patient dose. To this end, in diagnostic radiology, one finds the development of better films, X rays tubes, grids, screens and processing techniques, while in fluoroscopy, one sees the increased luminance of calcium tungstate. In interventional radiology, one finds an improvement in catheterization techniques and contrast agents. In nuclear medicine, the development of tracer techniques into modern cameras and isotopes such as technetium can be followed. In radiotherapy, one sees the early superficial X rays and radium sources gradually replaced with radon seeds, supervoltage, 60 Co and today's linear accelerators. Along with the incredible advances in imaging and therapeutic technologies comes the growing realization of the potential danger of radiation and the need to protect the patient (as well as physicians, ancillary personnel and the general population) from unnecessary radiation. The important lesson learned is that we must walk a tightrope, balancing the benefits and risks of any technology utilizing radiation to produce the greatest benefits at the lowest acceptable risk. The alternative techniques using non-ionizing radiation will have to be considered as part of the general armamentarium for medical imaging whenever radiation consequences are unacceptable. (author)

    The aim of this study is to gain insight into the individual user acceptance of PACS by the radiology department staff of the Ghent University Hospital. Hereto a basic--direct effects only--form of UTAUT was assessed. Ninety-four questionnaires were distributed and 56 usable questionnaires were returned (19 radiologists - 37 technologists). The questionnaire consisted of scales of Venkatesh et al. [13] for performance expectancy (PE), effort expectancy (EE), facilitating conditions (FC), social influence (SI), self-efficacy (SE), attitude (ATT), anxiety (ANX) and behavioral intention (BI), and a scale of Moore et al. [22] to assess the perceived voluntariness of PACS-use. The reliability of all scales, except FC and voluntariness, was acceptable to good. The voluntariness scale was divided into a mandatoriness (MAN) and a voluntariness (VOL) measure. Both radiologists and technologists seem to welcome PACS, with radiologists having higher ratings on PE, EE, ATT, VOL and BI. Only PE and FC were salient for predicting BI, while EE and SI were not salient. Variance explained in behavioral intention to use PACS was 48%. Both radiologists and technologists were positive towards PACS and had strong intentions to use PACS. As other healthcare professionals, they appear to make their technology acceptance decision independent from their superiors, hereby focusing on usefulness rather than on ease of use. It is also important that support is supplied. Basic UTAUT is an adequate model to assess technology acceptance in a radiological setting.

  16. Statistics Refresher for Molecular Imaging Technologists, Part 2: Accuracy of Interpretation, Significance, and Variance.

    Farrell, Mary Beth

    2018-06-01

    This article is the second part of a continuing education series reviewing basic statistics that nuclear medicine and molecular imaging technologists should understand. In this article, the statistics for evaluating interpretation accuracy, significance, and variance are discussed. Throughout the article, actual statistics are pulled from the published literature. We begin by explaining 2 methods for quantifying interpretive accuracy: interreader and intrareader reliability. Agreement among readers can be expressed simply as a percentage. However, the Cohen κ-statistic is a more robust measure of agreement that accounts for chance. The higher the κ-statistic is, the higher is the agreement between readers. When 3 or more readers are being compared, the Fleiss κ-statistic is used. Significance testing determines whether the difference between 2 conditions or interventions is meaningful. Statistical significance is usually expressed using a number called a probability ( P ) value. Calculation of P value is beyond the scope of this review. However, knowing how to interpret P values is important for understanding the scientific literature. Generally, a P value of less than 0.05 is considered significant and indicates that the results of the experiment are due to more than just chance. Variance, standard deviation (SD), confidence interval, and standard error (SE) explain the dispersion of data around a mean of a sample drawn from a population. SD is commonly reported in the literature. A small SD indicates that there is not much variation in the sample data. Many biologic measurements fall into what is referred to as a normal distribution taking the shape of a bell curve. In a normal distribution, 68% of the data will fall within 1 SD, 95% will fall within 2 SDs, and 99.7% will fall within 3 SDs. Confidence interval defines the range of possible values within which the population parameter is likely to lie and gives an idea of the precision of the statistic being

    Purpose: Development of a save and effective protocol for analgosedation of patients undergoing painful interventional procedures. Material and Methods: In a prospective trial a consecutive series of 72 adult patients underwent analgosedation during painful interventions. A radiologist performed the analgosedation, the patients received a combination of a shortly effective piperidine derivative (Alfentanil [Rapifen trademark ]; 7.5-15 μg/kg body weight) and Benzodiazepine (midazolam [Dormicum trademark ]; 20 μg/kg body weight). After pre-procedure oxygenation patients were continuously monitored. Pain and discomfort were scored using an established visual-analog pain score (0-10). A control group (n=24) had received midazolam, pentazocine or fentanyl according to the study protocol. Results: All procedures could be carried out by an interventional radiologist and a nurse and/or technologist only. In 69/72 cases adequate analgosedation could be achieved. Injection of alfentanil was titrated, with a rapid onset and short acting effect of the analgesia. Patients reported an average pain score of 2.6 vs. 4.5 in the control group. Over 55% experienced no or mild pain (score 0-3), in the control group only 8% reached this level. Conclusion: A combination of shortly effective alfentanil and midazolam allows interventional radiologists to perform major procedures alone under effective analgosedation. This medication scheme is superior to the medication upon demand. (orig.) [de

    Eponyms serve the purpose of honoring individuals who have made important observations and discoveries. As with other fields of medicine, eponyms are frequently encountered in radiology, particularly in chest radiology. However, inappropriate use of an eponym may lead to potentially dangerous miscommunication. Moreover, an eponym may honor the incorrect person or a person who falls into disrepute. Despite their limitations, eponyms are still widespread in medical literature. Furthermore, in some circumstances, more than one individual may have contributed to the description or discovery of a particular anatomical structure or disease, whereas in others, an eponym may have been incorrectly applied initially and propagated for years in medical literature. Nevertheless, radiologic eponyms are a means of honoring those who have made lasting contributions to the field of radiology, and familiarity with these eponyms is critical for proper reporting and accurate communication. In addition, the acquisition of some historical knowledge about those whose names are associated with various structures or pathologic conditions conveys a sense of humanity in the field of medicine. In this article, the first of a multipart series, the authors discuss a number of chest radiology eponyms as they relate to neoplasms, including relevant clinical and imaging features, as well biographic information of the respective eponym׳s namesake.

  19. Evolution of the system of radiological protection

    International Nuclear Information System (INIS)

    2004-01-01

    The development of new radiological protection recommendations by the International Commission on Radiological Protection (ICRP) continues to be a strategically important undertaking, both nationally and internationally. With the growing recognition of the importance of stakeholder aspects in radiological protection decision making, regional and cultural aspects have also emerged as having potentially significant influence on how protection of the public, workers and the environment are viewed. Differing cultural aspects should therefore be considered by the ICRP in its development of new recommendations. Based on this assumption, the NEA organised the Asian Regional Conference on the Evolution of the System of Radiological Protection to express and explore views from the Far East. Held in Tokyo on 24-25 October 2002, the conference included presentations by the ICRP Chair as well as by radiological protection experts from Japan, the Republic of Korea, China and Australia. The distinct views and needs of these countries were discussed in the context of their regional and cultural heritages. These views, along with a summary of the conference results, are presented in these proceedings. (author)

    Disastrous radiation and nuclear meltdown require an intricate scale of emergency health and social care capacity planning framework. In Malaysia, multiple agencies are responsible for implementing radiological and nuclear safety and security. This research project focused on the Radiological Trauma Triage (RTT) System. This system applies patient's classification based on their injury and level of radiation sickness. This classification prioritizes on the diagnostic and treatment of the casualties which include resources estimation of the medical delivery system supply and demand. Also, this system consists of the leading rescue agency organization and disaster coordinator, as well as the technical support and radiological medical response teams. This research implemented and developed the resources planning simulator for radiological incidents management. The objective of the simulator is to assist the authorities in planning their resources while managing the radiological incidents within the Internal Treatment Area (ITA), Reception Area Treatment (RAT) and Hospital Care Treatment (HCT) phases. The majority (75%) of the stakeholders and experts, who had been interviewed, witnessed and accepted that the simulator would be effective to resolve various types of disaster and resources management issues.
