Center for Devices and Radiological Health Publications Index, August 1988

International Nuclear Information System (INIS)

1988-08-01

This is the first Publications Index to be published by the Center for Devices and Radiological Health. Previous indexes, titled 'Bureau of Radiological Health Publications Index', were published before the Center was formed in 1982 through the merger of the Bureau of Radiological Health and the Bureau of Medical Devices; the last of these indexes was published in October 1980. The 1988 edition contains records of medical device and radiological health documents authored or published by the Center from 1978 through 1986. It should not be considered all-inclusive since those documents for which bibliographic information was not available have been excluded. The Publications Index is being distributed to Center staff, state radiological health programs, and libraries on the Center's publication mailing list. The Center plans to update and publish the Index every other year to provide a convenient record of published Center documents

Patient Preferences in Regulatory Benefit-Risk Assessments: A US Perspective.

Science.gov (United States)

Johnson, F Reed; Zhou, Mo

Demands for greater transparency in US regulatory assessments of benefits and risks, together with growing interest in engaging patients in Food and Drug Administration regulatory decision making, have resulted in several recent regulatory developments. Although Food and Drug Administration's Center for Drug Evaluation and Research (CDER) and Center for Devices and Radiological Health (CDRH) have established patient-engagement initiatives, CDRH has proposed guidelines for considering quantitative data on patients' benefit-risk perspectives, while CDER has focused on a more qualitative approach. We summarize two significant studies that were developed in collaboration and consultation with CDER and CDRH. CDER encouraged a patient advocacy group to propose draft guidance on engaging patient and caregiver stakeholders in regulatory decision making for Duchenne muscular dystrophy. CDRH sponsored a discrete-choice experiment case study to quantify obese respondents' perspectives on "meaningful benefits." CDRH and CDER issued draft guidance in May and June 2015, respectively, on including patient-preference data in regulatory submissions. Both organizations face challenges. CDER is working on integrating qualitative data into existing evidence-based review processes and is exploring options for therapeutic areas not included on a priority list. CDRH has adopted an approach that requires patient-preference data to satisfy standards of valid scientific evidence. Although that strategy could facilitate integrating patient perspectives directly with clinical data on benefits and harms, generating such data requires building capacity.

Differences in Allelic Frequency and CDRH3 Region Limit the Engagement of HIV Env Immunogens by Putative VRC01 Neutralizing Antibody Precursors

Directory of Open Access Journals (Sweden)

Christina Yacoob

2016-11-01

Full Text Available Elicitation of broadly neutralizing antibodies remains a long-standing goal of HIV vaccine research. Although such antibodies can arise during HIV-1 infection, gaps in our knowledge of their germline, pre-immune precursor forms, as well as on their interaction with viral Env, limit our ability to elicit them through vaccination. Studies of broadly neutralizing antibodies from the VRC01-class provide insight into progenitor B cell receptors (BCRs that could develop into this class of antibodies. Here, we employed high-throughput heavy chain variable region (VH/light chain variable region (VL deep sequencing, combined with biophysical, structural, and modeling antibody analyses, to interrogate circulating potential VRC01-progenitor BCRs in healthy individuals. Our study reveals that not all humans are equally predisposed to generate VRC01-class antibodies, not all predicted progenitor VRC01-expressing B cells can bind to Env, and the CDRH3 region of germline VRC01 antibodies influence their ability to recognize HIV-1. These findings will be critical to the design of optimized immunogens that should consider CDRH3 interactions.

Radiological protection and public health: crossbreeding

Smeesters, Patrick; Pinak, Miroslav

2008-01-01

Full text: This paper summarizes the scope of activities, ongoing experience and current results of the Expert Group on the Public Health Perspective in Radiological Protection (EGPH) of the Committee of Radiological Protection and Public Health, OECD Nuclear Energy Agency. While the prime and general task of the EGPH group is looking at how the public health and radiation protection can better take an advantage of their respective perspectives, the following four areas have been explored in detail: a) Exposure to radon; b) Justification of medical exposures; c) Public health judgement and decision making based on new scientific evidence; and d) Management of individual differences. In most of these areas, a targeted telephone survey on public policies in selected countries was used for collecting information from stake holders (public, consumers groups, public health and radiation protection regulators, governmental bodies, medical practitioners, patients, scientific communities, NGOs, etc.). The presented paper also highlights key issues of collected information and summarises existing approaches and policies. The case study on exposure to radon collects national information on approaches to the management of domestic radon risks, focusing on the integration of radiation protection and public health aspects (quality of dwellings, overall quality of indoor air, perception of radon levels, position of radon risk in the pool of other risks). In the case of justification of medical exposures, the Group studies the applications of the justification principle in opportunistic screenings (responsibilities, management of the situation, risk assessment). The precautionary principle and its impact on policy judgement in the light of significant scientific uncertainties can have a large influence on radiological-protection decision making. The case study on public health judgement and decision making based on new scientific evidence is exploring how these uncertainties and

The health care value transparency movement and its implications for radiology.

Durand, Daniel J; Narayan, Anand K; Rybicki, Frank J; Burleson, Judy; Nagy, Paul; McGinty, Geraldine; Duszak, Richard

2015-01-01

The US health care system is in the midst of disruptive changes intended to expand access, improve outcomes, and lower costs. As part of this movement, a growing number of stakeholders have advocated dramatically increasing consumer transparency into the quality and price of health care services. The authors review the general movement toward American health care value transparency within the public, private, and nonprofit sectors, with an emphasis on those initiatives most relevant to radiology. They conclude that radiology, along with other "ancillary services," has been a major focus of early efforts to enhance consumer price transparency. By contrast, radiology as a field remains in the "middle of the pack" with regard to quality transparency. There is thus the danger that radiology value transparency in its current form will stimulate primarily price-based competition, erode provider profit margins, and disincentivize quality. The authors conclude with suggested actions radiologists can take to ensure that a more optimal balance is struck between quality transparency and price transparency, one that will enable true value-based competition among radiologists rather than commoditization.

Medina, Santiago L.; Altman, Nolan R.

2002-01-01

To describe the resources and strategies required to establish a health outcomes and economics center in radiology.Methods. Human and nonhuman resources required to perform sound outcomes and economics studies in radiology are reviewed.Results. Human resources needed include skilled medical and nonmedical staff. Nonhuman resources required are: (1) communication and information network; (2) education tools and training programs; (3) budgetary strategies; and (4) sources of income. Effective utilization of these resources allows the performance of robust operational and clinical research projects in decision analysis, cost-effectiveness, diagnostic performance (sensitivity, specificity, and ROC curves), and clinical analytical and experimental studies.Conclusion. As new radiologic technology and techniques are introduced in medicine, society is increasingly demanding sound clinical studies that will determine the impact of radiologic studies on patient outcome. Health-care funding is scarce, and therefore third-party payers and hospitals are demanding more efficiency and productivity from radiologic service providers. To meet these challenges, radiology departments could establish health outcomes and economics centers to study the clinical effectiveness of imaging and its impact on patient outcome. (orig.)

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

Strategic planning and radiology practice management in the new health care environment.

Science.gov (United States)

Sharpe, Richard E; Mehta, Tejas S; Eisenberg, Ronald L; Kruskal, Jonathan B

2015-01-01

Current comprehensive health care reform in the United States demands that policy makers, insurers, providers, and patients work in reshaping the health care system to deliver care that is both more affordable and of higher quality. A tectonic shift is under way that runs contrary to the traditional goal of radiology groups to perform and interpret large numbers of imaging examinations. In fact, radiology service requisitions now must be evaluated for their appropriateness, possibly resulting in a reduction in the number of imaging studies performed. To be successful, radiology groups will have to restructure their business practices and strategies to align with the emerging health care paradigm. This article outlines a four-stage strategic framework that has aided corporations in achieving their goals and that can be readily adapted and applied by radiologists. The four stages are (a) definition and articulation of a purpose, (b) clear definition of strategic goals, (c) prioritization of specific strategic enablers, and (d) implementation of processes for tracking progress and enabling continuous adaptation. The authors provide practical guidance for applying specific tools such as analyses of strengths, weaknesses, opportunities, and threats (so-called SWOT analyses), prioritization matrices, and balanced scorecards to accomplish each stage. By adopting and applying these tools within the strategic framework outlined, radiology groups can position themselves to succeed in the evolving health care environment. RSNA, 2015

Radiological health risks from accidents during transportation of spent nuclear fuels

International Nuclear Information System (INIS)

Chen, S.Y.; Yuan, Y.C.

1988-01-01

Potential radiological health risks from severe accident scenarios during the transportation of spent nuclear fuels are estimated. These extremely low probability, but potentially credible, scenarios are characterized by the U.S. Nuclear Regulatory Commission's Modal Study in terms of the maximum credible structural responses and/or the maximum credible cask temperature responses. In some accident scenarios, the spent nuclear fuel casks are assumed to be breached, resulting in the release of radioactivity to the atmosphere. Models have been developed to estimate radiological health consequences, including potential short-term exposures and health effects to individuals and potential long-term environmental dose commitments and health effects to the population. The population risks are calculated using state-level data, and the resulting overall health risks are compared for several levels of cleanup effort to determine the relative effects on long-term risks to the population in the event of an accident. 4 refs., 3 figs., 3 tabs

Given the changing climate of health care and the imperative to add value, radiologists must join forces with the rest of medicine to deliver better patient care in a more cost-effective, evidence-based manner. For several decades, interventional radiology has added value to the health care system through innovation and the provision of alternative and effective minimally invasive treatments, which have decreased morbidity, mortality, and overall cost. The clinical practice of interventional radiology embodies many of the features of Imaging 3.0, the program recently launched by the ACR. We provide a review of some of the major contributions made by interventional radiology and offer general principles from that experience, which are applicable to all radiologists.

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.

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.

This Necessary and Sufficient (N and S) set of standards is for Other Industrial, Radiological, and Non-Radiological Hazard Facilities at Oak Ridge National Laboratory (ORNL). These facility classifications are based on a laboratory-wide approach to classify facilities by hazard category. An analysis of the hazards associated with the facilities at ORNL was conducted in 1993. To identify standards appropriate for these Other Industrial, Radiological, and Non-Radiological Hazard Facilities, the activities conducted in these facilities were assessed, and the hazards associated with the activities were identified. A preliminary hazards list was distributed to all ORNL organizations. The hazards identified in prior hazard analyses are contained in the list, and a category of other was provided in each general hazard area. A workshop to assist organizations in properly completing the list was held. Completed hazard screening lists were compiled for each ORNL division, and a master list was compiled for all Other Industrial, Radiological Hazard, and Non-Radiological facilities and activities. The master list was compared against the results of prior hazard analyses by research and development and environment, safety, and health personnel to ensure completeness. This list, which served as a basis for identifying applicable environment, safety, and health standards, appears in Appendix A.

Costing in Radiology and Health Care: Rationale, Relativity, Rudiments, and Realities.

Science.gov (United States)

Rubin, Geoffrey D

2017-02-01

Costs direct decisions that influence the effectiveness of radiology in the care of patients on a daily basis. Yet many radiologists struggle to harness the power of cost measurement and cost management as a critical path toward establishing their value in patient care. When radiologists cannot articulate their value, they risk losing control over how imaging is delivered and supported. In the United States, recent payment trends directing value-based payments for bundles of care advance the imperative for radiology providers to articulate their value. This begins with the development of an understanding of the providers' own costs, as well as the complex interrelationships and imaging-associated costs of other participants across the imaging value chain. Controlling the costs of imaging necessitates understanding them at a procedural level and quantifying the costs of delivering specific imaging services. Effective product-level costing is dependent on a bottom-up approach, which is supported through recent innovations in time-dependent activity-based costing. Once the costs are understood, they can be managed. Within the high fixed cost and high overhead cost environment of health care provider organizations, stakeholders must understand the implications of misaligned top-down cost management approaches that can both paradoxically shift effort from low-cost workers to much costlier professionals and allocate overhead costs counterproductively. Radiology's engagement across a broad spectrum of care provides an excellent opportunity for radiology providers to take a leading role within the health care organizations to enhance value and margin through principled and effective cost management. Following a discussion of the rationale for measuring costs, this review contextualizes costs from the perspectives of a variety of stakeholders (relativity), discusses core concepts in how costs are classified (rudiments), presents common and improved methods for measuring

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

2007-01-01

The interaction between the health and the radiological protection areas has proved fundamental, in our work experience, for the quality of response to victims of accidents, involving ionizing radiation. The conceptions and basic needs comprehension of the adequate response, on these two areas, have brought changes to the essential behavior related to the victim's care, the protection response, the environment and waste production. The joint task of health professionals and radiological protection staff, as first responders, demonstrates that it is possible to adjust practices and procedures. The training of professionals of the radiological protection area by health workers, has qualified them on the basic notions of pre-hospital attendance, entitling the immediate response to the victim prior to the health team arrival, as well as the discussion on the basic concepts of radiological protection with the health professionals, along with the understanding of the health area with its specific needs on the quick response to imminent death risk, or even the necessary procedures of decontamination.

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.

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

This paper will present some of the key findings of a comparative Latin-American study on radiological risk perception in the health area. The project used a survey method to examine the social demands for information about radiological risks with regard to diagnostic and therapeutic applications. The following topics will be analysed: 1) The role of information as a means for feeling safe; 2) who should inform the public on radiological risks; and 3) what type of information the public would like to receive. A questionnaire was distributed to outpatient samples from ten countries: Argentine, Brazil, Colombia, Cuba, Ecuador, Mexico, Panama, Peru, Uruguay, and Spain, thanks to the collaboration of the different National Radioprotection Societies of the above mentionned countries, and of other concerned professionals (in case they didn't had any association at the time). Correspondence analysis and other techniques of optimal scaling will be used. The paper will discuss the main cross-cultural differences with regard to social demand for information about radiological risks. Our findings may have relevant implications for radiological risks communication programs. (author)

validation of Teleradiology. The Scientific Societies SIRM-AIMN-AINR and the Academic Institutions, together with the SNR, AIFM and the F.N.C.TSRM, the Regional Bodies and the Italian National Health Trusts are required to make a positive and constructive commitment to this new field, which has become the object of considerable attention and interests. While confirming that, if used correctly, this methodology will no doubt increase the overall efficiency of Diagnostic Imaging - in the primary interest of the patient's right to health - it is felt that attention should also be paid to the working practices of the Radiology Specialists and Radiology Technicians and to the training of both. It is necessary to standardise training and practice, and to make an integrated and coherent use of resources with respect to the healthcare goals we wish to attain. Many have described the undisputed advantages of Teleradiology, but there have been relatively few reports on the related risks and recommendations for its use. It is certain that an improper use of the method (forced& interpretation of the bill on complementary diagnostic activities, operational misunderstandings between Radiology Specialists and Radiology Technicians, rarefaction of the relationship between Radiologist and Patient, obligation to use teleconsultation in all situations) will lead to considerable disadvantages for all those working in the field of Radiology, specialists and radiology technicians alike. Therefore, by adopting this document, which is by no means against Teleradiology but for a rational use of the method and full awareness of what it actually implies, the Scientific Society intends on the one hand to participate actively and concretely in the process of regulating all those aspects of Teleradiology for which it is competent - rather than waiting for regulations to be imposed from above - and, on the other, to provide, through its highly qualified Study Group (Specialists in Radiology, Nuclear

Full text: Radiology had been introduced in Mongolia by the establishment of the first X-Ray room at the First State Central Hospital in 1934. First radiologists in Mongolia were invited from the former Soviet Union; V. Sokolov, P. Omelchenko and others worked at the ''Burevestnik'' X-ray equipment of Russian production with high X-ray exposure and low capacity; they could perform only limited arts of Xray studies like fluoroscopy of thorax, stomach, esophagus and roentgenography of skull and extremities. The second X- ray equipment has been presented by the close friend of Lenin, the Director of People's Commissariat of Health Protection of the Soviet Union, Dr. N.A. Semashko; the present had been dedicated to the 10th Anniversary of Mongolian Health Care sector. During the military maneuvers at Khalkhin- Gol in 1939, several province hospitals and military hospitals had been supplied by the Xray equipment. During the period 1959-1960 all province hospitals, specialized hospitals had got X-ray unit. In 1955, Radii 226 had been used at first time in Mongolia for a treatment. In 1959, the State Radiological Clinic had been founded as a branch of X-ray cabinet of the First State Central Hospital. By the initiative of the absolvent of University of Leipzig, German Democratic Republic, Dr. P. Onkhuudai, Laboratory of Nuclear Medicine was established on 31 PstP March 1975 at the First State Central Hospital, which performed urography, thyroid and liver studies using Iod-131, Au-198, Hg-203 isotopes. In 1982, the gamma-camera and radio immunological equipment had been donated by the World Health Organization, and the Laboratory of Nuclear Medicine had been reorganized into Department of Nuclear Laboratory. Afterwards, in 1992 CT and SPECT diagnostics had been introduced at the First State Central Hospital, therefore new possibilities for high quality radiological diagnostic in Mongolia had been created. In 2007 the Siemens Magnetom 0.3 Tesla had been installed at the

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.

1990-07-01

There is an increase in international laser safety requirements as part of the emphasis on world-wide standardization of products and regulations. In particular the documents which will evolve from the 1992 consolidation efforts of the European Community (EC) will impact both laser manufacturers and users. This paper provides a discussion of the current status of the various laser radiation standards. NORTH AMERICAN REQUIREMENTS United States Requirements on manufacturers from the Food and Drug Administration (FDA) have been in effect since 1975. The Center for Devices and Radiological Health (CDRH) within that agency ensures that these mandatory requirements [1] are satisfied. The CDRH regulations include the division of products into classes depending on their potential for hazard criteria for power measurement and requirements for product features labels and manuals and records and reports. Manufacturers must test products and certify that they comply with the CDRH requirements. User requirements are found in a standard published by the American National Standards Institute (ANSI) and in requirements from several individual states. Specific ANSI standards have also been published for fiber communications systems [34] and for lasers in medical applications [35]. Please note that the Appendix includes additional information on the standards discussed in this paper including sources for obtaining the documents. Canada In the past Canada has had requirements for two specified product categories (bar code scanners and educational lasers) [26 These will be replaced

Radiological controls integrated into design

Energy Technology Data Exchange (ETDEWEB)

Kindred, G.W. [Cleveland Electric Illuminating Co., Perry, OH (United States)

1995-03-01

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.

Boice, J.D. Jr.; Mandel, J.S.; Doody, M.M.; Yoder, R.C.; McGowan, R.

1992-01-01

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

Socioeconomic trends in radiology

Barneveld Binkhuysen, F.H.

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.)

Role of radiology in occupational medicine

International Nuclear Information System (INIS)

Vehmas, T.

2004-01-01

This review discusses the contribution of radiology to occupational medicine as well as work-related problems in radiology dept.s. Research issues are emphasized. Radiology has been used especially when diagnosing occupational respiratory and locomotive system problems and solvent-induced encephalo- and hepatopathy. The aim of research in these areas is usually to characterize occupational diseases and to identify physico-chemical hazards in the work place by comparing between groups of workers and non-exposed controls. Radiological imaging allows an objective characterization of the disease, and it may clarify the pathogenesis of the process and provide a useful epidemiological tool. Advanced statistical methods are often needed to adjust analyses for confounding variables. As the diagnostic requirements are increasing, more sensitive and sophisticated radiological methods, such as high-resolution computed tomography, magnetic resonance imaging and magnetic resonance spectroscopy, may be required for the early recognition of occupational health risks. This necessitates good cooperation between occupational health units and well-equipped imaging dept.s. Considering occupational problems in radiology departments, the increasing use of digital radiology requires ergonomic measures to control and prevent locomotive problems caused by work with computers. Radiation protection measures are still worth concern, especially in interventional radiology

The Indian Health Service (IHS) operates or contracts with Tribal groups to operate 50 hospitals and approximately 165 primary ambulatory care centers. These facilities contain approximately 275 medical and 800 dental diagnostic x-ray machines. IHS environmental health personnel in collaboration with the Food and Drug Administration's (FDA) Center for Devices and Radiological Health (CDRH) developed a diagnostic x-ray protection program including standard survey procedures and menu-driven calculations software. Important features of the program include the evaluation of equipment performance collection of average patient entrance skin exposure (ESE) measurements for selected procedures, and quality assurance. The ESE data, collected using the National Evaluation of X-ray Trends (NEXT) protocol, will be presented. The IHS Diagnostic X-ray Radiation Protection Program is dynamic and is adapting to changes in technology and workload

The Fukushima radiological emergency and challenges identified for future public health responses.

Miller, Charles W

2012-05-01

On 11 March 2011, northern Japan was rocked by first a magnitude 9.0 earthquake off the eastern coast and then an ensuing tsunami. The Fukushima Daiichi Nuclear Power Plant complex was hit by these twin disasters, and a cascade of events was initiated that led to radionuclide releases causing widespread radioactive contamination of residential areas, agricultural land, and coastal waters. Radioactive material from Japan was subsequently transmitted to locations around the globe, including the U.S. The levels of radioactive material that arrived in the U.S. were never large enough to be a concern for health effects, but the presence of this material in the environment was enough to create a public health emergency in the U.S. The radiation safety and public health communities in the U.S. are identifying challenges they faced in responding to this incident. This paper discusses three of those challenges: (1) The growing shortage of trained radiation subject matter experts in the field of environmental transport and dosimetry of radionuclides; (2) the need to begin expressing all radiation-related quantities in terms of the International System of Units; and (3) the need to define when a radiation dose is or is not one of "public health concern." This list represents only a small subset of the list of challenges being identified by public health agencies that responded to the Fukushima incident. However, these three challenges are fundamental to any radiological emergency response. Addressing them will have a significant positive impact on how the U.S. responds to the next radiological emergency.

Public health preparedness and response to a radiological terrorist attack

Given the potential for intentional malevolent acts, the security of radioactive sources should be ensured. In the event of a terrorist attack using a radioactive source, we should care not only about health concerns of victims, especially including first responders who suffer from radiation injury, but also public health activities with affected people during the long recovery phase. Regarding the radiological public health viewpoint, preventive efforts are also important. In fact, regulatory reform is progressing in Japan according to the code of conduct issued by IAEA. One of the difficulties of countermeasures for the security of radioactive sources in Japan is to establish a disposal facility for disused sealed radioactive sources, since radioactive waste has been additionally a point of contention in society since the nuclear disaster. This paper presents an overview of countermeasures for terrorist attacks using a radioactive source, from the viewpoint of public health in Japan including the results of survey targeted hospitals equipped with blood irradiation machines.

Global view on the radiological protection of patients: PAHO position paper

International Nuclear Information System (INIS)

Borras, C.

2001-01-01

The Pan American Health Organization/World Health Organization (PAHO/WHO), founded in 1902, initiated a radiological health programme in the 1950s. Within this programme, there are currently three lines of work: (a) radiology services; (b) radiation safety; and (c) radiological emergencies. Radiology services deals with health services for diagnostic and interventional imaging, and for radiation therapy. Radiation safety studies the three types of exposures to both ionizing and non-ionizing radiation: occupational; medical; and public. Radiological emergencies involve radioactive waste management programmes and emergency plans. The radiological protection of patients is addressed in each of these areas: (a) when analysing the infrastructure of radiology services; and (b) when determining medical exposures; and (c) when investigating overexposures in interventional or therapeutic procedures or under-doses in radiation therapy.

Radiology education: a radiology curriculum for all medical students?

Zwaan, Laura; Kok, Ellen M; van der Gijp, Anouk

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.

Toward raising the higher level of radiological nursing

International Nuclear Information System (INIS)

Kusama, Tomoko; Ban, Nobuhiko; Ono, Koji

2013-01-01

The role and purpose of nursing in the radiological field are discussed with essentials of radiological nursing for raising its higher level and needed fundamental education. The discussion is from the thought that, at Fukushima Nuclear Power Plant Accident (Mar. 2011), general medical staff including nurses are rather insufficient of radiological knowledge like the exposure, radiation effect and risk. In the medical radiological field, nurses are expected to play roles of arranging the circumstance for patient's ease like explanation about health effect/risk, appropriate nursing of them after radiological diagnosis, radiation protection of nurses themselves, and of environment. At such an emergency as the Accident, care for the acutely exposed victims, their decontamination and responding to patient's concern are necessary. At the later phase, also needed are nursing of victims undergoing health management done by authorities and of radiological workers concerned as well as the third item above. Therefore, fundamentals of radiological knowledge such as physics, exposure, health effects, protection, contamination, legal rules and risk communication are required in the education of nurses. Otherwise, this education can be conducted as a part of safety security and physical assessment. The Accident also gives us the importance of radiological risk communication with its victims. (T.T.)

Scott, H.L.; Maisler, J.

1993-01-01

Over the past year, the Department of Energy (DOE) Office of Health (EH-40) has taken a leading role in the development of new standardized radiological control training programs for use throughout the DOE complex. The Department promulgated its Radiological Control (RadCon) Manual in June 1992. To ensure consistent application of the criteria presented in the RadCon Manual, standardized radiological control core training courses and training materials have been developed for implementation at all DOE facilities. In producing local training programs, standardized core courses are to be supplemented with site-specific lesson plans, viewgraphs, student handbooks, qualification standards, question banks, and wallet-sized training certificates. Training programs for General Employee Radiological Training, Radiological Worker I and II Training, and Radiological Control Technician Training have been disseminated. Also, training committees under the direction of the Office of Health (EH-40) have been established for the development of additional core training courses, development of examination banks, and the update of the existing core training courses. This paper discusses the current activities and future direction of the DOE radiological control core training program

With the widespread ownership of smartphones, many health care professionals question the degree to which medically related smartphone applications are reliable. To assess the variety of smartphone applications relating to paediatric radiology and the presence of health care professional involvement in their development. As a secondary objective, we explore whether there are gaps within the paediatric radiology app market. The most popular smartphone marketplaces (Apple iTunes App Store, Blackberry Mobile Market, Google Play Android Market, Nokia Ovi, Samsung and Microsoft Windows Marketplace) were searched for terms relating to paediatric radiology. Cost, review ratings, number of downloads, health care involvement and target audience were recorded. Nine paediatric radiology applications were found in the Apple iTunes App Store and nine in the Google Play Android Market. The target audiences for all applications were health care professionals. None were available for patients or their caregivers. All applications were reported to have medical expertise in their development. All paediatric radiology applications were developed with the aid of a health care professional. Due to the small number available online, there is a potential gap in the marketplace for further applications in this field, possibly aimed at patients and their families. (orig.)

Text Simplification Using Consumer Health Vocabulary to Generate Patient-Centered Radiology Reporting: Translation and Evaluation.

Science.gov (United States)

Qenam, Basel; Kim, Tae Youn; Carroll, Mark J; Hogarth, Michael

2017-12-18

Radiology reporting is a clinically oriented form of documentation that reflects critical information for patients about their health care processes. Realizing its importance, many medical institutions have started providing radiology reports in patient portals. The gain, however, can be limited because of medical language barriers, which require a way for customizing these reports for patients. The open-access, collaborative consumer health vocabulary (CHV) is a terminology system created for such purposes and can be the basis of lexical simplification processes for clinical notes. The aim of this study was to examine the comprehensibility and suitability of CHV in simplifying radiology reports for consumers. This was done by characterizing the content coverage and the lexical similarity between the terms in the reports and the CHV-preferred terms. The overall procedure was divided into the following two main stages: (1) translation and (2) evaluation. The translation process involved using MetaMap to link terms in the reports to CHV concepts. This is followed by replacing the terms with CHV-preferred terms using the concept names and sources table (MRCONSO) in the Unified Medical Language System (UMLS) Metathesaurus. In the second stage, medical terms in the reports and general terms that are used to describe medical phenomena were selected and evaluated by comparing the words in the original reports with the translated ones. The evaluation includes measuring the content coverage, investigating lexical similarity, and finding trends in missing concepts. Of the 792 terms selected from the radiology reports, 695 of them could be mapped directly to CHV concepts, indicating a content coverage of 88.5%. A total of 51 of the concepts (53%, 51/97) that could not be mapped are names of human anatomical structures and regions, followed by 28 anatomical descriptions and pathological variations (29%, 28/97). In addition, 12 radiology techniques and projections represented

The occupational risks associated with the chemical toxicity of uranium can be overlooked during the processing, handling and storage of the material, as the radioactivity of the material is often used alone to assess the health consequences of exposure to uranium compounds. This note provides a summary of the current United Kingdom occupational standards for uranium based on radiation dose and/or chemical toxicity with a particular focus on intake via inhalation. A simple model is subsequently presented to allow a comparison to be drawn between the occupational exposure standard for chemical toxicity and radiological dose limit. Using these data a set of suggested limits on occupational exposure to airborne uranium is proposed that indicate where the legal annual radiological dose limit for workers or the Health and Safety Executive occupational exposure standard for chemical toxicity are at risk of being breached.

Evidence-based Practice of Radiology.

Science.gov (United States)

Lavelle, Lisa P; Dunne, Ruth M; Carroll, Anne G; Malone, Dermot E

2015-10-01

Current health care reform in the United States is producing a shift in radiology practice from the traditional volume-based role of performing and interpreting a large number of examinations to providing a more affordable and higher-quality service centered on patient outcomes, which is described as a value-based approach to the provision of health care services. In the 1990 s, evidence-based medicine was defined as the integration of current best evidence with clinical expertise and patient values. When these methods are applied outside internal medicine, the process is called evidence-based practice (EBP). EBP facilitates understanding, interpretation, and application of the best current evidence into radiology practice, which optimizes patient care. It has been incorporated into "Practice-based Learning and Improvement" and "Systems-based Practice," which are two of the six core resident competencies of the Accreditation Council for Graduate Medical Education and two of the 12 American Board of Radiology milestones for diagnostic radiology. Noninterpretive skills, such as systems-based practice, are also formally assessed in the "Quality and Safety" section of the American Board of Radiology Core and Certifying examinations. This article describes (a) the EBP framework, with particular focus on its relevance to the American Board of Radiology certification and maintenance of certification curricula; (b) how EBP can be integrated into a residency program; and (c) the current value and likely place of EBP in the radiology information technology infrastructure.

Discussion on concepts for radiological dosimetric quantities in the Japan Health Physics Society

International Nuclear Information System (INIS)

Takahashi, Fumiaki; Oda, Keiji

2007-01-01

Many dosimetric quantities have been used for radiation protection purpose. The International Commission on Radiological Protection (ICRP) has recommended protection quantities and the International Commission on Radiation Units and Measurements (ICRU) has introduced operational quantities to provide a reasonable estimate of the protection quantities. Enthusiastic discussions are continuously made on the issues of the dosimetric quantities, such as basic biological data for the definition of these quantities and applicability of the quantities to actual radiation protection practice. At the moment, some changes are being proposed concerning dosimetric quantities in the draft recommendations of ICRP, opened for consultation in recent years. Thus, the Japan Health Physics Society (JHPS) established the Expert Committee on concepts of Dosimetric Quantities used in radiological protection (ECDQ) in April 2005 to reviewed and discuss issues in the dosimetric quantities.

Accountable care organizations and radiology: threat or opportunity?

Science.gov (United States)

Abramson, Richard G; Berger, Paul E; Brant-Zawadzki, Michael N

2012-12-01

Although the anticipated rise of accountable care organizations brings certain potential threats to radiologists, including direct threats to revenue and indirect systemic changes jeopardizing the bargaining leverage of radiology groups, accountable care organizations, and other integrated health care delivery models may provide radiology with an important opportunity to reassert its leadership and assume a more central role within health care systems. Capitalizing on this potential opportunity, however, will require radiology groups to abandon the traditional "film reader" mentality and engage actively in the design and implementation of nontraditional systems service lines aimed at adding differentiated value to larger health care organizations. Important interlinked and mutually reinforcing components of systems service lines, derived from radiology's core competencies, may include utilization management and decision support, IT leadership, quality and safety assurance, and operational enhancements to meet organizational goals. Such systems-oriented service products, tailored to the needs of individual integrated care entities and supported by objective performance metrics, may provide market differentiation to shield radiology from commoditization and could become an important source of new nonclinical revenue.

Health Care Delivery Meets Hospitality: A Pilot Study in Radiology.

Steele, Joseph Rodgers; Jones, A Kyle; Clarke, Ryan K; Shoemaker, Stowe

2015-06-01

The patient experience has moved to the forefront of health care-delivery research. The University of Texas MD Anderson Cancer Center Department of Diagnostic Radiology began collaborating in 2011 with the University of Houston Conrad N. Hilton College of Hotel and Restaurant Management, and in 2013 with the University of Nevada, Las Vegas, William F. Harrah College of Hotel Administration, to explore the application of service science to improving the patient experience. A collaborative pilot study was undertaken by these 3 institutions to identify and rank the specific needs and expectations of patients undergoing imaging procedures in the MD Anderson Department of Diagnostic Radiology. We first conducted interviews with patients, providers, and staff to identify factors perceived to affect the patient experience. Next, to confirm these factors and determine their relative importance, we surveyed more than 6,000 patients by e-mail. All factors considered important in the interviews were confirmed as important in the surveys. The surveys showed that the most important factors were acknowledgment of the patient's concerns, being treated with respect, and being treated like a person, not a "number"; these factors were more important than privacy, short waiting times, being able to meet with a radiologist, and being approached by a staff member versus having one's name called out in the waiting room. Our work shows that it is possible to identify and rank factors affecting patient satisfaction using techniques employed by the hospitality industry. Such factors can be used to measure and improve the patient experience. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

In this paper authors deals with study of radiation protection at the Department of Radiology and Toxicology, Faculty of Health and Social Studies of University of South Bohemia. This department providing awareness of the concept of radiation protection in persons of different professions, who will come into contact with ionizing radiation sources. These are e.g. specialists in health services, employees in defectoscopy and industry, members of police and fire fighting services, etc. For these persons, the Department of Radiology and Toxicology was established at the Faculty of Health and Social Studies of University of South Bohemia that offer their relevant education in theory and practice of radiation problems that are accredited in following direction: bachelor study in Applied radiobiology and toxicology; bachelor study in Biophysics and medical techniques; and master study in Crisis radiobiology and toxicology. These specified subjects are arranged in such a way that the student can be introduced into the teaching text based on the concept and history of relevant problems, for example: radiation physics, ionizing radiation dosimetry, clinical dosimetry. In accordance with a survey implemented in the field of health services it was found that there is a lack of people with technical education in the field of radiation at the level of Bachelors. These requirements are most properly adhered to by the specialty 'Radiological Technician' that is currently being planned at the Faculty of Health and Social Studies and that will be subjected to the accreditation process. The specialty 'Radiological Assistant' was formerly accredited at the faculty, whose activity is different from that of the 'Radiological Technician', as defined by Law of the Czech Republic No. 96/2004 Sb

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

The possible occurrence of accidents involving sources of ionizing radiation calls for response plans to mitigate the consequences of radiological accidents. An emergency planning framework is suggested for institutions which use medical applications of ionizing radiation. Bearing in mind that the prevention of accidents is of prime importance in dealing with radioactive materials and other sources of ionizing radiation, it is recommended that emergency instructions and procedures address certain aspects of the causes of these radiological events. Issues such as identification of radiological events in medical practices and their consequences, protective measures, planning for an emergency response and maintenance of emergency capacity are considered.

Medical irradiation is the largest man-made contributor to the radiation dose received by the population of Great Britain, and diagnostic radiology is the most important component of medical irradiation. The work described here is a survey of the numbers and types of radiological examinations carried out in National Health Service hospitals in Great Britain in 1977. The overall level of diagnostic radiology in Great Britain as a whole is reported and separate estimates for England, Wales and Scotland are given. Discussion of topics such as the frequency of particular types of examination, the number of films per examination and the use of gonad shields is included, and the results of the present survey are compared with those of the last national survey which was carried out in 1957. Also reported is an estimate of the amount of radiology undertaken outside the Health Service. The findings will be combined with estimates of gonadal doses from the different examinations and child expectancy data to estimate the genetically significant dose to the population of Great Britain.

Health Risks of Diagnostic Radiology

International Nuclear Information System (INIS)

Al-Oraby, M.N.A.

2014-01-01

Exposure to ionizing radiation during diagnostic radiologic procedures carries small but real risks. Children, young adults and pregnant women are especially vulnerable. Exposure of patients to diagnostic energy levels of ionizing radiation should be kept to the minimum necessary to provide useful clinical information and allay patients concerns about radiation-related risks. Computerized Tomography (CT) accounts for two thirds of the cumulative patient dose from diagnostic radiological procedures and the cumulative dose from CT is rising as technological advances increase the number of indications and the capabilities of CT. Carcinogenesis and teratogenesis are the main concerns with ionizing radiation. The risk increases as the radiation dose increases. There is no minimum threshold and the risk is cumulative: a dose of 1 mSv once a year for 10 years is equivalent to a single dose of 10 mSv. Whenever practical, choose an imaging test that uses less radiation or no radiation and lengthen the periods between follow-up imaging tests. Some patients may avoid screening mammography because of fear of radiation-induced cancer, yet this test uses a very small radiation dose (0.6 mSv, much less than the annual dose from background radiation, 3.6 mSv).

A radiological control implementation guide

International Nuclear Information System (INIS)

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 workshop provides a forum for exchange of information and experience among regulators, scientists and governmental and non-governmental organisations in the areas of radiological protection and public health. This is the second in the series of NEA workshops on this subject. The first Science and Values in Radiological Protection workshop was held in Helsinki in January 2008 and hosted by the Radiation and Nuclear Safety Authority of Finland (STUK). The workshop focussed on developing a shared understanding between various stakeholders and identifying the elements of a framework more suited to the integration of new scientific and technological developments and socio-political considerations in radiological protection. This second workshop focusses on radiological protection issues that are currently facing us, and that continue to pose challenges to our world today.

Efficient use of resources in organizations is one of the most important duties of managers. Appropriate allocation of resources can help managers to do this well. The aim of this study was to determine the cost of radiology services and to compare it with governmental tariffs (introduced by the Ministry of Health in Iran). This was a descriptive and applied study that was conducted using the retrospective approach. First, activity centers were identified on the basis of five main groups of hospital activities. Then, resources and resource drivers, activities, and hospital activity drivers were identified. At the next step, the activities related to the delivery of radiology process were identified. Last, through allocation of activities cost to the cost objects, the cost price of 66 services that were delivered in the radiology department were calculated. The data were collected by making checklists, using the hospital's information system, observations, and interviews. Finally, the data were analyzed using the non-parametric Wilcoxon test, Microsoft Excel, and SPSS software, version 18. The findings showed that from the total cost of wages, materials, and overhead obtained, the unit cost of the 66 cost objects (delivered services) in the Radiology Department were calculated using the ABC method (Price of each unit of Nephrostogram obtained $15.8 and Cystogram obtained $18.4). The Kolmogorov-Smirnov test indicated that the distribution of data of cost price using the ABC method was not normal (p = 0.000). The Wilcoxon test showed that there was a significant difference between the cost of services and the tariff of radiology services (p = 0.000). The cost of delivered services in radiology departments was significantly higher than approved tariffs of the Ministry of Health, which can have a negative impact on the quality of services.

The basis for a radiological protection program to the health area of the State University of Campinas (UNICAMP)

1994-01-01

There are some sectors in the Health Area of the State University of Campinas (UNICAMP) that present great potential risks from the viewpoint of radiation protection. The aim of this work is to establish the basis a radiological protection program applicable to these sectors. The Diagnostic Radiology Services and the Laboratory of Cardiac Catheterization of the Hospital de Clinicas have been analyzed, as well as the Radiotherapy Services of the Center for Integral Assistance to the Women Health (CAISM). This work was mainly supported by national and international regulations related to the operative and employment aspects of the equipment and radiation sources used in the health area. Regulations related to area and individual monitoring of workers were also used. Results show that the interior of the rooms where the equipment and radiation sources are located is classified as controlled area, whereas the neighborhoods of the rooms are mostly free areas. In order to improve the radiological protection conditions, only some of the operative and employment aspects need to be modified regarding equipment and radiation sources. In this way, routine personal monitoring would not be further required. Since all the workers have their annual mean equivalent doses below 3/10 of the primary limits of the applicable equivalent dose, routine individual monitoring could be exempted.

Nuclear or radiologic emergencies are defined as incidents that are caused by radioactive substance or by other sources of radiation and can pose a serious hazard to public health. In case of nuclear or radiologic emergencies, radioactive rays will damage the human body and bring about psychological and mental stress, resulting in a series of social psychological effects. The key to medical rescue for nuclear or radiologic emergencies is to take effective measures which can minimize the body harm resulting from nuclear or radiologic emergencies and maintain social stability. This article reviews the personnel protection, on-the-spot salvage, treatments of various harm, and prevention of public psychological effect following nuclear or radiologic emergencies. (authors)

Parikh, Jay R; Harolds, Jay A; Bluth, Edward I

2017-08-01

Workplace bullying is common in health care and has recently been reported in both radiology and radiation oncology. The purpose of this article is to increase awareness of bullying and its potential consequences in radiology and radiation oncology. Bullying behavior may involve abuse, humiliation, intimidation, or insults; is usually repetitive; and causes distress in victims. Workplace bullying is more common in health care than in other industries. Surveys of radiation therapists in the United States, student radiographers in England, and physicians-in-training showed that substantial proportions of respondents had been subjected to workplace bullying. No studies were found that addressed workplace bullying specifically in diagnostic radiology or radiation oncology residents. Potential consequences of workplace bullying in health care include anxiety, depression, and health problems in victims; harm to patients as a result of victims' reduced ability to concentrate; and reduced morale and high turnover in the workplace. The Joint Commission has established leadership standards addressing inappropriate behavior, including bullying, in the workplace. The ACR Commission on Human Resources recommends that organizations take steps to prevent bullying. Those steps include education, including education to ensure that the line between the Socratic method and bullying is not crossed, and the establishment of policies to facilitate reporting of bullying and support victims of bullying.

The BHO RAP-1 has been developed to: (a) ensure the availability of an effective radiological assistance capability to ensure the protection of persons and property; (b) provide guidelines to RAP-1 Team personnel for the evaluation of radiological incidents and implementation of corrective actions; (c) maintain liaison with other DOE installations, Federal, State and local organizations which may become involved in radiological assistance operations in Region I; and (d) encourage development of a local capability to cope with radiological incidents

Radiological impacts of uranium recovery in the phosphate industry

International Nuclear Information System (INIS)

Ryan, M.T.

1981-01-01

This article characterizes the occupational and public radiological health impacts associated with phosphate mining and milling. These impacts are related to the phosphate industry's uranium production potential and are compared with those associated with conventional uranium mining and milling. The radiological impacts resulting from occupational and nonoccupational exposures are assessed. Occupational exposures in phosphate facilities are compared to background exposures and radiological population dose assessments, which characterize important radionuclides and exposure pathways. The following conclusions were reached: (1) public consequences of phosphate mining will occur whether or not uranium is recovered as a by-product, (2) radiological consequences of phosphate mining may be comparable to those associated with uranium mining and milling per unit uranium production, (3) radiological impacts via surface waterways and crops fertilized with uranium-bearing phosphates are of minor consequence, and (4) major radiological public health problems associated with phosphate mining are related to radon and radon progeny exposures in structures built on reclaimed lands or with phosphate mining residues, although the magnitudes of these impacts are difficult to evaluate with current data

For the past several years, the health physics/radiation protection field has experienced a significant shortage of qualified professionals. The shortage is expected to continue for foreseeable future given the continued demand by both nuclear and medical facilities and the expected growth in the areas of waste management and environmental remediation. In response to such a shortage, beginning in the fall of 1984, Georgia Institute of Technology (Georgia Tech) established a video-based instruction program that enables professionals in the nuclear field to earn a master of science degree in health physics/radiological engineering while working at a distant nuclear facility. The admission criteria and curricular requirements for the program are identical to those for the resident (on-campus) students (except that weekly attendance at departmental seminars is excused). The program is designed for students with undergraduate degrees in health physics, engineering, or appropriate sciences such as physics, chemistry, or biology. A total of 50 quarter credit hours is required, so that a student who takes one course per quarter can complete the program in four years

This position is significantly different from a traditional classroom instructor or a facility health physicist, and provides workers with a level of radiological safety guidance not routinely provided by typical training programs. Implementation of this position presents a challenge in providing effective instruction, requiring rapport with the radiological worker not typically developed in the routine radiological training environment. The value of this unique training is discussed in perspective with cost-savings through better radiological control. Measures of success were developed to quantify program performance and providing a realistic picture of the benefits of providing one-on-one or small group training. This paper provides a description of the unique features of the program, measures of success for the program, a formula for implementing this program at other facilities, and a strong argument for the success (or failure) of the program in a time of increased radiological safety emphasis and reduced radiological safety budgets.

Radiological control implementation guide

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

Radiological Dispersal Polonium-210, and Lessons for Public Health

Whitcomb, R. C.; Miller, C. W.

On November 23, 2006, Alexander Litvinenko died in London as a result of being poisoned with Polonium-210. Public health authorities in the United Kingdom (UK) subsequently found Polonium-210 contamination at a number of locations in and around London. UK authorities have determined that citizens of 48 countries other than the UK, including the United States, may have been exposed to this contamination. UK authorities asked the CDC to contact approximately 160 individuals who may have been exposed to Po-210. These citizens have been advised that their risk of adverse health effects is likely to be low, but, if they are concerned, they should contact their primary health care provider. In turn, physicians are referred to state and local public health departments or CDC for further information on Po-210, including where they can seek testing of 24 hour urine samples for Po-210, if desired. CDC posted guidance for members of the public and physicians on its web site, and it responded to numerous inquiries from national media. Working with our UK colleagues, CDC developed guidelines for judging when a measurement of Po-210 in urine was or was not a level of concern. Because the death of Mr. Litvinenko is an ongoing criminal investigation, one of the major challenges of this response to what is a radiological dispersal device event has been the inability to obtain all of the technical detail desired to perform assessments. This has complicated the ability to communicate effectively with citizens and members of the public health community. These and other lessons learned from this response will help prepare the public health community to respond more effectively to future contamination events involving radioactive dispersal in the environment.(author)

Hazardous radiological waste-dental and environmental perspective

Dental radiology is concerned with maxillo-facial radiological diagnostic procedure. It is meant for patient welfare and to generate diagnostically useful information, which can be utilized for patient welfare. If injudiciously used, it can become a source of harmful effluents and solid waste, which may pose risk to health and environment. Professionals of dental radiology should be aware about their responsibility to dispose such waste in the rightful manner to fulfil their medical pledge and ethics of doing no harm. (author)

The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

Analysis of radiology business models.

Enzmann, Dieter R; Schomer, Donald F

2013-03-01

As health care moves to value orientation, radiology's traditional business model faces challenges to adapt. The authors describe a strategic value framework that radiology practices can use to best position themselves in their environments. This simplified construct encourages practices to define their dominant value propositions. There are 3 main value propositions that form a conceptual triangle, whose vertices represent the low-cost provider, the product leader, and the customer intimacy models. Each vertex has been a valid market position, but each demands specific capabilities and trade-offs. The underlying concepts help practices select value propositions they can successfully deliver in their competitive environments. Copyright © 2013 American College of Radiology.

Comparison of the radiological and chemical toxicity of lead

Energy Technology Data Exchange (ETDEWEB)

Beitel, G.A.; Mott, S.

1995-03-01

This report estimates the worst-case radiological dose to an individual from ingested lead containing picocurie levels of radionuclides and then compares the calculated radiological health effects to the chemical toxic effects from that same lead. This comparison provides an estimate of the consequences of inadvertently recycling, in the commercial market, lead containing nominally undetectable concentrations of radionuclides. Quantitative expressions for the radiological and chemical toxicities of lead are based on concentrations of lead in the blood stream. The result shows that the chemical toxicity of lead is a greater health hazard, by orders of magnitude, than any probable companion radiation dose.

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

Radiological assessment. A textbook on environmental dose analysis

Energy Technology Data Exchange (ETDEWEB)

Till, J.E.; Meyer, H.R. (eds.)

1983-09-01

Radiological assessment is the quantitative process of estimating the consequences to humans resulting from the release of radionuclides to the biosphere. It is a multidisciplinary subject requiring the expertise of a number of individuals in order to predict source terms, describe environmental transport, calculate internal and external dose, and extrapolate dose to health effects. Up to this time there has been available no comprehensive book describing, on a uniform and comprehensive level, the techniques and models used in radiological assessment. Radiological Assessment is based on material presented at the 1980 Health Physics Society Summer School held in Seattle, Washington. The material has been expanded and edited to make it comprehensive in scope and useful as a text. Topics covered include (1) source terms for nuclear facilities and Medical and Industrial sites; (2) transport of radionuclides in the atmosphere; (3) transport of radionuclides in surface waters; (4) transport of radionuclides in groundwater; (5) terrestrial and aquatic food chain pathways; (6) reference man; a system for internal dose calculations; (7) internal dosimetry; (8) external dosimetry; (9) models for special-case radionuclides; (10) calculation of health effects in irradiated populations; (11) evaluation of uncertainties in environmental radiological assessment models; (12) regulatory standards for environmental releases of radionuclides; (13) development of computer codes for radiological assessment; and (14) assessment of accidental releases of radionuclides.

Fifty years of radiological protection

International Nuclear Information System (INIS)

2007-01-01

On 21 March 1957, the Steering Committee for Nuclear Energy of the Organisation for European Economic Co-operation established the Working Party on Public Health and Safety. From this early date onwards, radiological protection formed a central part of the work of what was to become the OECD Nuclear Energy Agency. Now, 50 years later, the Committee on Radiation Protection and Public Health (CRPPH) has commissioned this historical review of half a century of work and accomplishments. Over this period, the key topics in radiological protection have been identified, debated and addressed by the CRPPH. This report brings this history to life, presenting the major questions in the context of their time, and of the personalities who worked to address them. The developments and views of the past condition how we are able to assess and manage radiological risks today, as well as how we may adjust to challenges that will or could emerge in the coming years. This heritage is thus an important element for the CRPPH to consider as it looks forward to its next 50 years of accomplishments. (author)

Radiological health assessment of natural radioactivity in the vicinity of Obajana cement factory, North Central Nigeria

Directory of Open Access Journals (Sweden)

Omoniyi Matthew Isinkaye

2015-01-01

Full Text Available Measurements of activity concentrations of natural radionuclides in and around Obajana cement factory, North Central Nigeria have been carried out in this study to determine the activity levels of natural radionuclides in different environmental matrices in order to assess the radiological health hazards associated with the use of these matrices by the local population. A low-background Pb-shielded gamma spectroscopic counting assembly utilizing NaI (Tl detector was employed for the measurements. The results show that sediment samples have the highest activity concentrations of all the radionuclides relative to soil, farmland soil, and rock samples. The radium equivalent activity and indoor gamma dose rates together with the corresponding annual effective indoor doses evaluated were found to be lower than their permissible limits. It suffices to say, that contrary to age-long fear of radiation risks to the population in the vicinity of the cement factory, no excessive radiological health hazards either indoors and/or outdoors is envisaged. Therefore, the environmental matrices around the factory could be used without any restrictions.

Improving diagnosis in health care: perspectives from the American College of Radiology.

2017-09-26

In September of 2014, the American College of Radiology joined a number of other organizations in sponsoring the 2015 National Academy of Medicine report, Improving Diagnosis In Health Care. Our presentation to the Academy emphasized that although diagnostic errors in imaging are commonly considered to result only from failures in disease detection or misinterpretation of a perceived abnormality, most errors in diagnosis result from failures in information gathering, aggregation, dissemination and ultimately integration of that information into our patients' clinical problems. Diagnostic errors can occur at any point on the continuum of imaging care from when imaging is first considered until results and recommendations are fully understood by our referring physicians and patients. We used the concept of the Imaging Value Chain and the ACR's Imaging 3.0 initiative to illustrate how better information gathering and integration at each step in imaging care can mitigate many of the causes of diagnostic errors. Radiologists are in a unique position to be the aggregators, brokers and disseminators of information critical to making an informed diagnosis, and if radiologists were empowered to use our expertise and informatics tools to manage the entire imaging chain, diagnostic errors would be reduced and patient outcomes improved. Heath care teams should take advantage of radiologists' ability to fully manage information related to medical imaging, and simultaneously, radiologists must be ready to meet these new challenges as health care evolves. The radiology community stands ready work with all stakeholders to design and implement solutions that minimize diagnostic errors.

Eletronuclear Healthcare Foundation is the Institution responsible for the actions of health response involving ionizing radiation in the area of Nuclear Power Plant Almirante Alvaro Alberto in Angra dos Reis. Because of their specific assignments and references for being in training health manpower in the field of ionizing radiation developed a range of Training Courses for Professionals Area Health to prepare them for Response to Radiological and Nuclear Accidents. Modules are proposed specifically for the professional response of the Technical Level and Higher Level, the level Pre-hospital and hospital. These modules are further divided into specific levels or modules, Basic or Introductory, Intermediate and Advanced. Are applied pretests and post tests to monitor the content of fixing, maintaining a historical series of reviews. Your content is theoretical and practical applications developed in 30 to 48 hours, with simulations (drills) and distribution of educational materials. We already have more than 80 applications training, focusing on internal staff and external to the institution, developing interesting partner with the Armed Forces and Civil Defense. It still maintained a link on the institution seeking access and download over 400 titles on the subject and exchange of information and experiences. For improving the teaching material, the authors launched in 2011 the first manual in Portuguese on the subject with new revised edition in 2013: 'Manual of Medical Actions In Radiological Emergencies'. The results indicate increased knowledge and appropriateness of the themes and the strategy proposed for this activity, demonstrating yet passed that information can be multiplied and meets the growing demand of the country that has hosted and will host international events relevant at QBNRE risk.

Already before the events of September 11th 2001 concern was raised about the spread of orphan sources and their potential use in Radiological Dispersion Devices by terrorist groups. Although most of the simulated scenarios foresee a rather limited direct health impact on the population, the affected region would suffer from the indirect consequences such as social disruption, cleanup requirements and economic costs. The nature of such a radiological attack would anyway be different compared to conventional radiological accidents, basically because it can happen anywhere at any time. Part of the response resides in a general preparedness scheme incorporating attacks with Radiological Dispersion Devices. Training of different potential intervention teams is essential. The response would consist of a prioritised list of actions adapted to the circumstances. As the psychosocial dimension of the crisis could be worse than the purely radiological one, an adapted communication strategy with the public aspect would be a key issue.

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

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

Health literacy in vascular and interventional radiology: a comparative analysis of online patient education resources.

The Internet is frequently accessed by patients as a resource for medical knowledge. However, the provided material is typically written at a level well above the recommended 7th grade level. A clear understanding of the capabilities, limitations, risks, and benefits of interventional radiology by patients, both current and prospective, is hindered when the textual information offered to the public is pitched at a level of sophistication too high for general comprehension. In January 2013, all 25 patient education resources from the Cardiovascular and Interventional Radiology Society of Europe (CIRSE) Web site ( http://www.cirse.org ) and all 31 resources from the Society of Interventional Radiology (SIR) Web site ( http://www.sirweb.org ) were analyzed for their specific level of readability using ten quantitative scales: Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook, Gunning fog index, New Fog Count, Coleman-Liau index, FORCAST formula, Fry graph, Raygor Readability Estimate, and New Dale-Chall. Collectively, the patient education resources on the CIRSE Web site are written at the 12.3 grade level, while the resources on the SIR Web site are written at the 14.5 grade level. Educational health care materials available on both the CIRSE and the SIR Web sites are presented in language in the aggregate that could be too difficult for many lay people to fully understand. Given the complex nature of vascular and interventional radiology, it may be advantageous to rewrite these educational resources at a lower reading level to increase comprehension.

Radiation exposures experienced by workers are widely explained. The first evidences of biological effects, the implications for human health and the radiological protection have been covered. The conceptual structure that covers the radiological protection and adequate protection without limiting benefits, the scientific basis of radiology, the benefits and risks of the radiological protection are specified. The effective per capita doses are exposed in medical uses both for Latin America and for other regions in the average radiology, dental radiology, nuclear medicine and radiotherapy. The manners of occupational exposures in the medicine are presented. Industrial uses have also its average effective dose in the industrial irradiation, industrial radiography and radioisotopes production. Within the natural radiation the natural sources can significantly contribute to occupational exposure and have their average effective dose. Occupational medical surveillance to be taken into industrial sites is detailed. In addition, the plan of international action for the solution of dilemmas of occupational exposures is mentioned and the different dilemmas of radioactive exposure are showed. The external irradiation, the acute diseases by radiations, the cutaneous syndrome of the chronic radiation, the radioactive contamination, the internal radioactive contamination, the combined lesion and accidental exposures are also treated [es

Cardiovascular and interventional radiology

White, R.I. Jr.

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

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.

Lääperi, A L

1996-01-01

The purpose of this study was to analyse the cost structure of radiological procedures in the intermediary referral hospitals and general practice and to develop a cost accounting system for radiological examinations that takes into consideration all relevant cost factors and is suitable for management of radiology departments and regional planning of radiological resources. The material comprised 174,560 basic radiological examinations performed in 1991 at 5 intermediate referral hospitals and 13 public health centres in the Pirkanmaa Hospital District in Finland. All radiological departments in the hospitals were managed by a specialist in radiology. The radiology departments at the public health care centres operated on a self-referral basis by general practitioners. The data were extracted from examination lists, inventories and balance sheets; parts of the data were estimated or calculated. The radiological examinations were compiled according to the type of examination and equipment used: conventional, contrast medium, ultrasound, mammography and roentgen examinations with mobile equipment. The majority of the examinations (87%) comprised conventional radiography. For cost analysis the cost items were grouped into 5 cost factors: personnel, equipment, material, real estate and administration costs. The depreciation time used was 10 years for roentgen equipment, 5 years for ultrasound equipment and 5 to 10 years for other capital goods. An annual interest rate of 10% was applied. Standard average values based on a sample at 2 hospitals were used for the examination-specific radiologist time, radiographer time and material costs. Four cost accounting versions with varying allocation of the major cost items were designed. Two-way analysis of variance of the effect of different allocation methods on the costs and cost structure of the examination groups was performed. On the basis of the cost analysis a cost accounting program containing both monetary and

Cost/benefit of high technology in diagnostic radiology

Goethlin, J.H.

1987-08-01

High technology is frequently blamed as a main cause for the last decade's disproportionate rise in health expenditure. Total costs for all large diagnostic and therapeutic appliances are typically less than 1% of annual expenditure on health care. CT, DSA, MRI, interventional radiology, ESWL, US, mammography, computers in radiology and PACS may save 10-80% of total cost for diagnosis and treatment of disease. Expenditure on high technology is in general vastly overestimated. Because of its medical utility, a slower deployment cannot be desirable. (orig.)

Due to the short term, long term and genetic effects of radiation, the work with radioactive materials requires special protection measures. The objective of radiological protection is to assure the occupational health of the workers by maintaining the dose levels as low as reasonably achievable. The radiological protection measures implanted in the NUCLEBRAS fuel element factory are described. The philosophy and practical measures taken are explained, and a comparison between radiation protection and industrial safety norms is made. The result of this work shows that the radiological safety of the element factory is assured. (author) [pt

Radiological monitoring of food in Cuba

Jerez V, S.F.

1996-01-01

The appearing of the problem for protecting the environment from radioactive contamination is not an accidental matter. The introduction into the earth crust of radioactive material coming from nuclear weapons, accidents, wastes, etc, has caused, as a consequence, the contamination of the biosphere. The extensive trade of food in our country has made necessary the establishment of radiological monitoring in food, which was organized by the Department of Public Health. The structure, functions, characteristics and aspects related to radiological monitoring of food in Cuba are shown in the present paper. The organization and resources for performing the monitoring program, both for normal conditions and for nuclear and/or radiological emergency cases, are detailed. (author). 12 refs., 2 figs

Quality assurance (QA) is a fundamental component of every successful radiology operation. A radiology QA program must be able to efficiently and effectively monitor and respond to quality problems. However, as radiology QA has expanded into the depths of radiology operations, the task of defining and measuring quality has become more difficult. Key performance indicators (KPIs) are highly valuable data points and measurement tools that can be used to monitor and evaluate the quality of services provided by a radiology operation. As such, KPIs empower a radiology QA program to bridge normative understandings of health care quality with on-the-ground quality management. This review introduces the importance of KPIs in health care QA, a framework for structuring KPIs, a method to identify and tailor KPIs, and strategies to analyze and communicate KPI data that would drive process improvement. Adopting a KPI-driven QA program is both good for patient care and allows a radiology operation to demonstrate measurable value to other health care stakeholders. Copyright © 2015 Mosby, Inc.

1988-01-01

The Medical Physics Group at the School of Medicine of the Complutense University of Madrid, started a programme on the study of radiation doses in relation to Diagnostic Radiology in the area of Madrid in 1986, in cooperation with the Department of Health and Consumer Affairs, and several Madrid area hospitals as well as some Outpatient Centers. In Spain, the National Health Service (NHS) (through the National Institute of Health, INSALUD), potentially cares for the health of approximately 94% of the population. This figure reaches 99% at the Community of Madrid. Radiological examinations are performed mainly in Hospitals and Outpatient Centers (the latter making up a first link in the patient's radiological diagnosis). Private Diagnostic Radiology is used by the remaining 6% of the population (not taking into account the population attended in military hospitals), and by patients who in spite of having access to NHS Diagnostic Radiology Services, prefer to choose the private sector for different reasons. Besides the data we obtained during the first year of study from four large Madrid-area hospitals (and a few outpatient centers); we have used data furnished by the Department of Health and Consumer Affairs, the INSALUD and other sources

Radiological emergency: Malaysian preparedness and response

Planning and preparation in advance for radiological emergencies can help to minimise potential public health and environmental threats if and when an actual emergency occurs. During the planning process, emergency response organisations think through how they would respond to each type of incident and the resources that will be needed. In Malaysia, planning, preparation for and response to radiological emergencies involve many parties. In the event of a radiological emergency and if it is considered a disaster, the National Security Council, the Atomic Energy Licensing Board and the Malaysian Nuclear Agency (Nuclear Malaysia) will work together with other federal agencies, state and local governments, first responders and international organisations to monitor the situation, contain the release, and clean up the contaminated site. Throughout the response, these agencies use their protective action guidelines. This paper discusses Malaysian preparedness for, and response to, any potential radiological emergency. (authors)

Innovation and entrepreneurship in health care can help solve the current health care crisis by creating products and services that improve quality and convenience while reducing costs. To effectively drive innovation and entrepreneurship within the current health care delivery environment, academic institutions will need to provide education, promote networking across disciplines, align incentives, and adapt institutional cultures. This article provides a general review of entrepreneurship and commercialization from the perspective of academic radiology departments, drawing on information sources in several disciplines including radiology, medicine, law, and business. Our review will discuss the role of universities in supporting academic entrepreneurship, identify drivers of entrepreneurship, detail opportunities for academic radiologists, and outline key strategies that foster greater involvement of radiologists in entrepreneurial efforts and encourage leadership to embrace and support entrepreneurship.

Information extraction from multi-institutional radiology reports.

Science.gov (United States)

Hassanpour, Saeed; Langlotz, Curtis P

2016-01-01

The radiology report is the most important source of clinical imaging information. It documents critical information about the patient's health and the radiologist's interpretation of medical findings. It also communicates information to the referring physicians and records that information for future clinical and research use. Although efforts to structure some radiology report information through predefined templates are beginning to bear fruit, a large portion of radiology report information is entered in free text. The free text format is a major obstacle for rapid extraction and subsequent use of information by clinicians, researchers, and healthcare information systems. This difficulty is due to the ambiguity and subtlety of natural language, complexity of described images, and variations among different radiologists and healthcare organizations. As a result, radiology reports are used only once by the clinician who ordered the study and rarely are used again for research and data mining. In this work, machine learning techniques and a large multi-institutional radiology report repository are used to extract the semantics of the radiology report and overcome the barriers to the re-use of radiology report information in clinical research and other healthcare applications. We describe a machine learning system to annotate radiology reports and extract report contents according to an information model. This information model covers the majority of clinically significant contents in radiology reports and is applicable to a wide variety of radiology study types. Our automated approach uses discriminative sequence classifiers for named-entity recognition to extract and organize clinically significant terms and phrases consistent with the information model. We evaluated our information extraction system on 150 radiology reports from three major healthcare organizations and compared its results to a commonly used non-machine learning information extraction method.

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.

Radiological protection at particle accelerators: An overview

International Nuclear Information System (INIS)

Thomas, R.H.

1991-01-01

Radiological protection began with particle accelerators. Many of the concerns in the health physics profession today were discovered at accelerator laboratories. Since the mid-1940s, our understanding has progressed through seven stages: observation of high radiation levels; shielding; development of dosimetric techniques; studies of induced activity and environmental impact; legislative and regulatory concerns; and disposal. The technical and scientific aspects of accelerator radiation safety are well in hand. In the US, there is an urgent need to move away from a ''best available technology'' philosophy to risk-based health protection standards. The newer accelerators will present interesting radiological protection issues, including copious muon production and high LET (neutron) environments

Sardanelli, Francesco; Di Leo, Giovanni; Hunink, Myriam G.; Gilbert, Fiona J.; Krestin, Gabriel P.

2010-01-01

To provide an overview of evidence-based medicine (EBM) in relation to radiology and to define a policy for adoption of this principle in the European radiological community. Starting from Sackett's definition of EBM we illustrate the top-down and bottom-up approaches to EBM as well as EBM's limitations. Delayed diffusion and peculiar features of evidence-based radiology (EBR) are defined with emphasis on the need to shift from the demonstration of the increasing ability to see more and better, to the demonstration of a significant change in treatment planning or, at best, of a significant gain in patient outcome. The ''as low as reasonably achievable'' (ALARA) principle is thought as a dimension of EBR while EBR is proposed as part of the core curriculum of radiology residency. Moreover, we describe the process of health technology assessment in radiology with reference to the six-level scale of hierarchy of studies on diagnostic tests, the main sources of bias in studies on diagnostic performance, and levels of evidence and degrees of recommendations according to the Centre for Evidence-Based Medicine (Oxford, UK) as well as the approach proposed by the GRADE working group. Problems and opportunities offered by evidence-based guidelines in radiology are considered. Finally, we suggest nine points to be actioned by the ESR in order to promote EBR. Radiology will benefit greatly from the improvement in practice that will result from adopting this more rigorous approach to all aspects of our work. (orig.)

2011-01-01

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.

Dias, Camila Rodrigues; Pereira, Marluce Rodrigues; Freire, André Pimenta

2017-12-01

Radiology processes are commonly supported by Radiology Information System (RIS), Picture Archiving and Communication System (PACS) and other software for radiology. However, these information technologies can present usability problems that affect the performance of radiologists and physicians, especially considering the complexity of the tasks involved. The purpose of this study was to extract, classify and analyze qualitatively the usability problems in PACS, RIS and other software for radiology. A systematic review was performed to extract usability problems reported in empirical usability studies in the literature. The usability problems were categorized as violations of Nielsen and Molich's usability heuristics. The qualitative analysis indicated the causes and the effects of the identified usability problems. From the 431 papers initially identified, 10 met the study criteria. The analysis of the papers identified 90 instances of usability problems, classified into categories corresponding to established usability heuristics. The five heuristics with the highest number of instances of usability problems were "Flexibility and efficiency of use", "Consistency and standards", "Match between system and the real world", "Recognition rather than recall" and "Help and documentation", respectively. These problems can make the interaction time consuming, causing delays in tasks, dissatisfaction, frustration, preventing users from enjoying all the benefits and functionalities of the system, as well as leading to more errors and difficulties in carrying out clinical analyses. Furthermore, the present paper showed a lack of studies performed on systems for radiology, especially usability evaluations using formal methods of evaluation involving the final users.

Mental health effects from radiological accidents and their social management

International Nuclear Information System (INIS)

Brenot, J.; Charron, S.; Verger, P.

2000-01-01

Mental health effects resulting from exposure to radiation have been identified principally in the context of large radiological accidents. They cover an extended scope of manifestations in relation with the notion of stress: increase of some hormones, modifications in mental concentration, symptoms of anxiety and depression, psycho-somatic diseases, deviation behaviours, and, on the long term, a possible post-traumatic stress disorder (PTSD). The main results come from the Three Mile Island, Goiania, and Chernobyl accidents and several modifying factors have been identified. Considering those facts, diverse social responses can be brought to reduce the detriment to affected individuals and communities. Medical treatments are necessary for persons who suffer from pathological diseases. In most cases, a structured public health follow-up is required to establish the seriousness of the health problems, to forecast the extent of medical and psychological assistance, and to inform people who express fears and worries. Social assistance is always valuable under various forms: financial compensations, preferential medical care, and particular advantages concerning working and living conditions. If this social assistance is necessary and helpful, it also induces a loss in personal adjustment capability and initiative capacity. To overcome those negative impacts, some guidelines to authorities' action can be set up. But the best approach, not excluding the previous ones, remains problem solving at the local level through community responsibilization; some instructive examples come from the Chernobyl experience.

The Society for Computer Applications in Radiology (SCAR) Transforming the Radiological Interpretation Process (TRIP) Initiative aims to spearhead research, education, and discovery of innovative solutions to address the problem of information and image data overload. The initiative will foster interdisciplinary research on technological, environmental and human factors to better manage and exploit the massive amounts of data. TRIP will focus on the following basic objectives: improving the efficiency of interpretation of large data sets, improving the timeliness and effectiveness of communication, and decreasing medical errors. The ultimate goal of the initiative is to improve the quality and safety of patient care. Interdisciplinary research into several broad areas will be necessary to make progress in managing the ever-increasing volume of data. The six concepts involved are human perception, image processing and computer-aided detection (CAD), visualization, navigation and usability, databases and integration, and evaluation and validation of methods and performance. The result of this transformation will affect several key processes in radiology, including image interpretation; communication of imaging results; workflow and efficiency within the health care enterprise; diagnostic accuracy and a reduction in medical errors; and, ultimately, the overall quality of care.

Objectives: To determine the frequency of needle stick injury in health care workers of radiology department. Study type, settings and duration: Cross sectional, observational study conducted at the Radiology department of Aga Khan University hospital from January 2000 to May 2010. Subject and Methods: All self-reported needle stick injuries data of Health care workers of radiology department was recorded. The personnel involved (Radiologist, resident, radiographer, nurses etc), area of working and the causes of injury were identified including the procedural or post procedural details. Patient's status of hepatitis or blood borne infection was also noted. Data was recorded and analyzed in Excel worksheet. Results: A total of 55 health workers reported needle stick injuries at all sections of radiology departments with maximum number needle stick injuries at general radiography, fluoroscopy and IVP section. Radiographers and radiology residents received the maximum number of injuries. Major cause of injury was cannulation however, many injuries occurred during disposing or handling of bin. In majority of cases the patients were not infected with any known blood borne infections. Conclusions: Doctors and nurses get needle-stick injuries while carrying out clinical procedures, while, ancillary staff get infected post procedure during disposal of garbage. Policy message: Good occupational health and safety practices must be promoted to all staff. Safer disposal of needles is an important area where practice and procedure needs to be carefully reviewed. It is necessary to undertake a risk assessment, to offer counseling and Post Exposure Prophylaxis and treatment where necessary. (author)

This presentation explores the relationship of some principles of economics and ethics as applied to the radiologic sciences community. The adversarial nature of these two topics is discussed, as well as how they work together in the improvement of health care delivery. With the health care system ''under the microscope,'' we must stringently watch our productivity and quality. These topics are also discussed in relation to the professional education of students and the continuing education of staff, educators, managers, and physicians in the radiologic sciences. With the rapid growth of more complex health technologies, the changing characteristics of health problems, and a commitment to serve the total population, a true team effort is required in health care delivery

Radiological protection system in the era of nuclear renaissance expectation for development of radiological protection system

International Nuclear Information System (INIS)

Toyomatsu, Hideki

2008-01-01

The current radiological protection system, which was established mainly by the ICRP and UNSCEAR, has contributed to the prevention of potential radiological health hazards, and has been a fundamental concept during the development of nuclear energy. Through a detailed discussion regarding the new ICRP recommendations, the world nuclear industry has reached a consensus that the current radiological protection system keeps its integrity in principle although it involves some remaining issues, such as the disposal of radioactive waste. In order to maximize the advantages of nuclear energy while keeping the integrity of radiological protection system, it is essential to address the characteristics of radiation, which is specific to nuclear energy, so that nuclear energy can coexist with other energy sources. The three basic principles of radiological protection (i.e., justification, optimization and dose limits), which were completed in the 1990 recommendations of ICRP, should be retained as the basic concepts for the future radiological protection system in order to maintain the continuity and consistency of the radiological protection system. The radiological protection system can be furthermore developed only by combining the above three principles with best practices extracted from utilities' field experience. The significant reduction of radiation exposures received by members of the public and radiation workers in the field has resulted from the efforts by the world utilities to achieve the optimization. In order to correctly apply the theory to the work practices, it is essential to see how the theory is practically used in the field. Such a process should be also emphasized in the revision work of the IAEA Basic Safety Standards (BSS), which is currently under progress. Integrating the theory in the work practices is the key to the true development of nuclear renaissance, which could lead to the establishment of the nuclear safety regime. (author)

The concept of error and malpractice in radiology.

Science.gov (United States)

Pinto, Antonio; Brunese, Luca; Pinto, Fabio; Reali, Riccardo; Daniele, Stefania; Romano, Luigia

2012-08-01

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. The etiology of radiological error is multifactorial. Errors fall into recurrent patterns. Errors arise from poor technique, failures of perception, lack of knowledge, and misjudgments. 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. Errors are an inevitable part of human life, and every health professional has made mistakes. To improve patient safety and reduce the risk from harm, we must accept that some errors are inevitable during the delivery of health care. We must play a cultural change in medicine, wherein errors are actively sought, openly discussed, and aggressively addressed. Copyright © 2012 Elsevier Inc. All rights reserved.

The role of medical imaging is increasingly integral to health care, drug discovery, biology, and other life sciences. The changes that are occurring call for innovation in the training of the medical imaging experts of tomorrow. In their previous book, Radiology Education: The Scholarship of Teaching and Learning (2008), the editors addressed the philosophical and theoretical underpinnings of scholarship in radiology education. Now, in The Practice of Radiology Education: Challenges and Trends, they focus on the application of these concepts within educational programs for radiology residents and fellows. The book has three sections on Curriculum, Programs and Trainees, and Leadership and Resources. Within this framework, each chapter addresses theory and principles, practical issues, and resources and literature relevant to educational practice. The contributors are educators in radiology from around the world, providing a global perspective on the main challenges facing medical imaging education and the potential strategies required to meet these challenges. It is hoped that the book will assist in attaining the ultimate goal of radiology education: to help patients. (orig.)

Topical problems of quality assurance and quality control in diagnostic radiology are discussed and possible solutions are shown. Complex units are differentiated with reference to physicians, technicians, organization of labour, methods of examination and indication. Quality control of radiologic imaging systems should involve three stages: (1) simple tests carried out by radiologic technicians, (2) measurements by service technicians, (3) testing of products by the manufacturer and independent governmental or health service test agencies.

To preserve radiology rounds in the changing health care environment, we have introduced virtual radiology rounds, an initiative enabling clinicians to remotely review imaging studies with the radiologist. We describe our initial experience with virtual radiology rounds and referring provider impressions. Virtual radiology rounds, a web-based conference, use remote sharing of radiology workstations. Participants discuss imaging studies by speakerphone. Virtual radiology rounds were piloted with the Neonatal Intensive Care Unit (NICU) and the Congenital Cardiovascular Care Unit (CCVCU). Providers completed a survey assessing the perceived impact and overall value of virtual radiology rounds on patient care using a 10-point scale. Pediatric radiologists participating in virtual radiology rounds completed a survey assessing technical, educational and clinical aspects of this methodology. Sixteen providers responded to the survey; 9 NICU and 7 CCVCU staff (physicians, nurse practitioners and fellows). Virtual radiology rounds occurred 4-5 sessions/week with an average of 6.4 studies. Clinicians rated confidence in their own image interpretation with a 7.4 average rating for NICU and 7.5 average rating for CCVCU. Clinicians unanimously rated virtual radiology rounds as adding value. NICU staff preferred virtual radiology rounds to traditional rounds and CCVCU staff supported their new participation in virtual radiology rounds. Four of the five pediatric radiologists participating in virtual radiology rounds responded to the survey reporting virtual radiology rounds to be easy to facilitate (average rating: 9.3), to moderately impact interpretation of imaging studies (average rating: 6), and to provide substantial educational value for radiologists (average rating: 8.3). All pediatric radiologists felt strongly that virtual radiology rounds enable increased integration of the radiologist into the clinical care team (average rating: 8.8).

The objective of Radiological Protection is to guarantee that neither people, be they workers or members of the public, or the environment are exposed to radiological risks considered by society to be unacceptable. Among the various resources available to meet this objective is Research and Development (R and D), which is carried out in three areas: I. Radiological protection of persons: (a) knowledge of the biological effects of radiations, in order to determine the relationship that exists between radiation exposure dose and its effects on health; (b) the development of new personal dosimetry techniques in order to adapt to new situations, instrumental techniques and information management technologies allowing for better assessment of exposure dose; and (c) development of the principle of radiological protection optimisation (ALARA), which has been set up internationally as the fundamental principle on which radiological protection interventions are based. II. Assessment of environmental radiological impact, the objective of which is to assess the nature and magnitude of situations of exposure to ionising radiations as a result of the controlled or uncontrolled release of radioactive material to the environment, and III.Reduction of the radiological impact of radioactive wastes, the objective of which is to develop radioactive material and waste management techniques suitable for each situation, in order to reduce the risks associated with their definitive management or their release to the environment. Briefly described below are the strategic lines of R and D of the CSN, the Electricity Industry, Ciemat and Enresa in the aforementioned areas. (Author)

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

Strengthening the scientific basis of radiological protection

The overarching objective of the radiological protection system is to contribute to an appropriate level of protection against the harmful effects of radiation exposure, without unjustifiably limiting the desired results from the human activity causing exposure. Such a balance is achieved by understanding as best as possible the scientific characteristics of radiation exposure and the related health effects, and by taking this knowledge into consideration when judging which protection decisions will ensure the best balance between social and economic aspects and risks. In general, the existing radiological protection system, on which national regulations are built in virtually every country in the world, works well and does not underestimate protection needs for either individuals or exposed populations as a whole. The latest International Commission on Radiological Protection (ICRP) recommendations, which define this protection system, were formed after a long and open dialogue with the public, where expert views were actively collected and discussed at national, regional and international levels. Although the radiological protection system is very effective, and there is no current need for a prompt revision, it is important nonetheless to keep a watchful eye on the latest scientific results, and to work to ensure that the entire radiological protection community is kept up to date on evolving and emerging scientific issues. In this way, potential or actual scientific changes can be appropriately identified and in turn can stimulate reflection on changes that might be needed in the protection system, in policy, in regulation and in practice. Such reflection should benefit from the input of other scientific disciplines and interested stakeholders. To contribute to this process, the NEA Committee on Radiological Protection and Public Health (CRPPH) has periodically reviewed and released reports on the state of the art in radiological protection science (see NEA

A Federal Radiological Monitoring and Assessment Center (FRMAC) is established in response to a Lead Federal Agency (LFA) or State request when a radiological emergency is anticipated or has occurred. The FRMAC coordinates the off-site monitoring, assessment, and analysis activities during such an emergency. The FRMAC response is divided into three phases. FRMAC Phase 1 is a rapid, initial-response capability that can interface with Federal or State officials and is designed for a quick response time and rapid radiological data collection and assessment. FRMAC Phase 1 products provide an initial characterization of the radiological situation and information on early health effects to officials responsible for making and implementing protective action decisions

Radiological health risk evaluation of radium contaminated land: A real life implementation

A plot of land, currently used for dairy farming, has been contaminated over the years with radium due to the operation of one of the world's largest radium production plants. Within the framework of a global remediation approach for the plant surroundings, the land owner needed advice for a future destination of the land. Therefore, the radium contamination was accurately mapped, and on the basis of its severity a practically feasible subdivision of the land into four plots was proposed. For all four plots, the radiological risk was evaluated for the current type of land use and for possible alternative types. Hence a clear and usable advice could be formulated to the authorities reconciling public health, economic and practical issues. (authors)

The US Department of Energy (DOE) has sponsored a Radiological Assistance Program (RAP) since the 1950's. The RAP is designed to make DOE resources available to other DOE facilities, state, tribal, local, private businesses, and individuals for the explicit purpose of assisting during radiological incidents. The DOE has an obligation, through the Atomic Energy Act of 1954, as amended, to provide resources through the Federal Radiological Emergency Response Plan (FRERP, Nov. 1985) in the event of a radiological incident. Toward this end, the RAP program is implemented on a regional basis, and has planned for an incremental response capability with regional coordination between states and DOE response elements. This regional coordination is intended to foster a working relationship between DOE radiological assistance elements and those state, tribal, and local agencies responsible for first response to protect public health and safety

The future policy for radiological protection

2004-01-01

At the end of the 1990's, the International Commission on Radiological Protection (ICRP) launched a process for establishing new recommendations, which are expected to serve as guidelines for national systems of radiological protection. Currently the ICRP's proposed recommendations are being subjected to extensive stakeholder comment and modifications. The NEA Committee on Radiation Protection and Public Health (CRPPH) has been actively involved in this process. Part of the Committee's work has been to undertake collaborative efforts with the ICRP through, for example, the organisation of broad stakeholder fora. The first of these, held in Taormina, Italy in 2002, focused on the development of a policy basis for the radiological protection of the environment. The second forum, held in Lanzarote, Spain in April 2003, addressed the latest concepts and approaches in the ICRP proposed recommendations for a system of radiological protection. During this meeting, the ICRP listened to the views of various stakeholder groups, including radiological protection regulators, environmental protection ministries, the nuclear power industry and NGOs. As a result, the ICRP modified its proposals to better reflect stakeholder needs and wishes. This report presents the outcomes of the discussions, examining what the ICRP proposed and how its proposals have been affected and modified as a result of stakeholder input. (author)

Interest in quality assurance processes and quality improvement in diagnostic radiology is being driven by a number of factors. These include the high cost and complexity of radiological equipment, acknowledgement of the possibility of increasing doses to patients, and the importance of radiological diagnosis to patient management within the health care environment. To acknowledge these interests, clinical audits have been introduced and, in Europe, mandated under a European Directive (Council Directive 97/47/EURATOM). Comprehensive clinical audits focus on clinical management and infrastructure, patient related and technical procedures, and education and research. This publication includes a structured set of standards appropriate for diagnostic radiology, an audit guide to their clinical review, and data collection sheets for the rapid production of reports in audit situations. It will be a useful guide for diagnostic radiology facilities wishing to improve their service to patients through timely diagnosis with minimal radiation dose.

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.

They are exposed to different types of health hazards namely, fumes, gases and dust, which are risk factors for developing occupational diseases. Therefore, the aim of this study was to perform chest radiology to determine the occupational hazards of cement dust on the lungs of cement mill workers. This study was carried out in the Department of Physiology, Faculty of Health and Medical Sciences, Hamdard University Karachi, Pakistan, during the period June to August 2000. In this study 50, apparently healthy volunteer male cement mill workers were randomly selected with an average of 13 years exposure with age ranging from 20-60 years. They were matched with 50, healthy male control subjects in terms of age, height, weight and socioeconomic status. Both groups met with exclusion criteria as per standard. Radiology was performed by Trophy radiology. Results: The present study demonstrated 12% of cases with interstitial lung disease and 2% of cases with pleural thickening and chronic bronchitis in cement mill workers. Conclusion: Exposure to cement dust causes interstitial lung disease, pleural thickening and chronic bronchitis in cement mill workers. (author)

Planning the medical response to radiological accidents

International Nuclear Information System (INIS)

1998-01-01

Radioactive substances and other sources of ionizing radiation are used to assist in diagnosing and treating diseases, improving agricultural yields, producing electricity and expanding scientific knowledge. The application of sources of radiation is growing daily, and consequently the need to plan for radiological accidents is growing. While the risk of such accidents cannot be entirely eliminated, experience shows that most of the rare cases that have occurred could have been prevented, as they are often caused by human error. Recent radiological accidents such as those at Chernobyl (Ukraine 1986), Goiania (Brazil 1987), San Salvador (El Salvador 1989), Sor-Van (Israel 1990), Hanoi (Viet Nam 1992) and Tammiku (Estonia 1994) have demonstrated the importance of adequate preparation for dealing with such emergencies. Medical preparedness for radiological accidents must be considered an integral part of general emergency planning and preparedness and established within the national framework for radiation protection and safety. An IAEA Technical Committee meeting held in Istanbul in 1988 produced some initial guidance on the subject, which was subsequently developed, reviewed and updated by groups of consultants in 1989, 1992 and 1996. Special comments were provided by WHO, as co-sponsor of this publication, in 1997. This Safety Report outlines the roles and tasks of health authorities and hospital administrators in emergency preparedness for radiological accidents. Health authorities may use this document as the basis for their medical management in a radiological emergency, bearing in mind that adaptations will almost certainly be necessary to take into account the local conditions. This publication also provides information relevant to the integration of medical preparedness into emergency plans

Evaluation and analysis of the integrative course "Radiological Anatomy" established since 2007 at the Medical School Hannover (MHH) in comparison with conventional education. Anatomy and radiology are usually taught separately with a considerable time lag. Interdisciplinary teaching of these associated subjects seems logical for several reasons. Therefore, the integrative course "Radiological Anatomy" was established in the second year of medical education, combining these two closely related subjects. This interdisciplinary course was retrospectively evaluated by consideration of a student questionnaire and staff observations. The advantages and disadvantages of integrative teaching in medical education are discussed. The course ratings were excellent (median 1; mean 1.3 on a scale of 1 to 6). This is significantly (p radiology increased during the course (88 %). According to the students' suggestions the course was enhanced by a visitation in the Department of Radiology and the additional topic central nervous system. Integrative teaching of anatomy and radiology was well received by the students. Both, anatomical and radiological comprehension and the motivation to learn were improved. However, it should be considered, that the amount of work and time required by the teaching staff is considerably increased compared to traditional teaching. © Georg Thieme Verlag KG Stuttgart · New York.

2009-01-01

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

This report presents the technical details of RISKIND, a computer code designed to estimate potential radiological consequences and health risks to individuals and the collective population from exposures associated with the transportation of spent nuclear fuel. RISKIND is a user-friendly, interactive program that can be run on an IBM or equivalent personal computer under the Windows{trademark} environment. Several models are included in RISKIND that have been tailored to calculate the exposure to individuals under various incident-free and accident conditions. The incident-free models assess exposures from both gamma and neutron radiation and can account for different cask designs. The accident models include accidental release, atmospheric transport, and the environmental pathways of radionuclides from spent fuels; these models also assess health risks to individuals and the collective population. The models are supported by databases that are specific to spent nuclear fuels and include a radionuclide inventory and dose conversion factors. In addition, the flexibility of the models allows them to be used for assessing any accidental release involving radioactive materials. The RISKIND code allows for user-specified accident scenarios as well as receptor locations under various exposure conditions, thereby facilitating the estimation of radiological consequences and health risks for individuals. Median (50% probability) and typical worst-case (less than 5% probability of being exceeded) doses and health consequences from potential accidental releases can be calculated by constructing a cumulative dose/probability distribution curve for a complete matrix of site joint-wind-frequency data. These consequence results, together with the estimated probability of the entire spectrum of potential accidents, form a comprehensive, probabilistic risk assessment of a spent nuclear fuel transportation accident.

Rehani, M.M.

1995-01-01

The branch of quality assurance is now taking a new direction towards total quality management (TQM). Being of industrial origin, the concepts and terminologies in TQM are alien to medical and paramedical professionals. However, the impetus it has already made in other areas of health sciences makes medical physicists left out when diagnostic radiology does not encompass TQM. The purpose of this paper is to introduce the terms used in TQM and some aspects of its application to diagnostic radiology. (author). 12 refs., 1 tab

Dosimetry in Diagnostic Radiology for Paediatric Patients

International Nuclear Information System (INIS)

2013-01-01

Concern about the radiation dose to children from diagnostic radiology examinations has recently been popularly expressed, particularly as related to computed tomography (CT) procedures. This involves the observation that children can receive doses far in excess of those delivered to adults, in part due to the digital nature of the image receptors that may give no warning to the operator of the dose to the patient. Concern for CT examinations should be extended to the broad range of paediatric diagnostic radiological procedures responsible for radiation doses in children, especially as factors, such as increased radiosensitivity and the longer life expectancy of children, increase the associated radiation risk. In all cases, owing to the added paediatric radiological examination factor of patient size and its associated impact on equipment selection, clinical examination protocol and dosimetric audit, the determination of paediatric dose requires a distinct approach from adult dosimetry associated with diagnostic radiological examinations. In response to this, there is a need to inform health professionals about standardized methodologies used to determine paediatric dose for all major modalities such as general radiography, fluoroscopy and CT. Methodologies for standardizing the conduct of dose audits and their use for the derivation and application of diagnostic reference levels for patient populations, that vary in size, are also required. In addition, a review is needed of the current knowledge on risks specific to non-adults from radiation, and also an analysis of the management of factors contributing to dose from paediatric radiological examinations. In 2007, the IAEA published a code of practice, Dosimetry in Diagnostic Radiology: An International Code of Practice, as Technical Reports Series No. 457 (TRS 457). TRS 457 recommends procedures for dosimetric measurement and calibration for the attainment of standardized dosimetry, and addresses requirements

Ethical problems in radiology: radiological consumerism.

Science.gov (United States)

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.

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 Radiological Protection Plan - PPR, quoted by the Regulatory Standard 32, requires to be maintained at the workplace and at the disposal of the worker's inspection the PPR, for it to be aware of their work environment and the damage that can be caused by misuse of ionizing radiation. Objective: to discuss the interface between PPR and ethical reflection. Method: this is a reflective study. Discussion and results: regulatory norm 32 points out that the worker who conducts activities in areas where there are sources of ionizing radiation should know the risks associated with their work. However, it is considered that the sectors of hospital radiology the multidisciplinary health team is exposed to ionizing radiation and has not always aware of the harm caused by it, so end up unprotected conduct their activities. Concomitantly, recent studies emphasize the radiological protection and concern for the dangers of radiation on humans, but rather refer to the legislation about the radiological protection. In this context an ethical reflection is necessary, seeking to combine work ethics liability to care in protecting themselves and the other with the institutional conditions for this protection becomes effective

Perspectives on the chemical and radiological hazards of uranium

International Nuclear Information System (INIS)

Stansbury, P.S.

1987-01-01

Uranium is unique among the elements because it presents chemical and radiological hazards of comparable magnitude. Although the biological effects of a heavy metal damaging the kidneys are vastly different from the actions of an alpha-emitting nuclide in the lung or bone tissues, there are some perceptual and phenomenological similarities of note to health physicists. In a broad sense, the amount of uranium that could cause chemical kidney damage or pose a radiation hazard could go unnoticed in the work place. Once taken into the body, the chemical action or the radiological insult progresses without any warning signals. Ultrasensitive bioassay techniques could detect the presence of uranium in the body and quantify an intake that is known to have occurred. The adverse health effect of either the chemical or radiological mode of action is catastrophic: kidney failure on one hand, cancer on the other. Two other parallelisms should be noted. The natural loss of nephrons is part of the aging process. Similarly 15 to 20% of the population die of naturally caused cancer. Thus, the effects of uranium exposure mimic natural effects in unexposed populations. There are suspected adverse health effects at low levels of exposure to uranium. Even though there may be good reasons for suspecting low-level effects, both chemical and radiological, there is very little definitive evidence that these effects occur in human populations. 7 refs., 1 fig., 1 tab

Full text: This work summarises the main ideas and achievements of the Science and Values in Radiological Protection Workshop that was held on 15-17 January 2008 in Helsinki, Finland. In the view of developing of new radiological applications and emerging scientific phenomena it has been recognized a need to develop a shared understanding of emerging challenges for radiological protection among scientific and regulatory communities, public and other concerned stake holders. In response to this the Committee of Radiation Protection and Public Health of the OECD Nuclear Energy Agency and Radiation and Nuclear Safety Authority of Finland tried to initiate a process of longer-term reflection on scientific and societal issues that might challenge radiological protection in the coming years. Among general issues like radiological policy issues, improvement of understanding between research and policy communities, sharing views on emerging scientific issues, there were addressed several scientific issues, like non-targeted effects, individual sensitivity; and circulatory diseases. The main focus of these discussions was to elaborate potential 'what if' scenarios and propose feasible solutions at various levels. These discussions addressed effects that are not direct and evident consequence of the initial lesions produced at the cellular and DNA level like bystander responses, genomic instability, gene induction, adaptive responses and low dose. Particular interest was paid to an extrapolation of risk estimates to low doses and role of Linear Non-Threshold theory in setting regulatory principles. Individual radio-sensitivity and identification of genes that are suspected of having an influence on it were also discussed in one of the Breakout Sessions. Another Breakout Session addressed circulatory diseases. There is emerging evidence in the A-bomb survivors and in other exposed groups that ionising radiation also causes other diseases than cancer, such as circulatory

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

Radiological reporting has generated large quantities of digital content within the electronic health record, which is potentially a valuable source of information for improving clinical care and supporting research. Although radiology reports are stored for communication and documentation of diagnostic imaging, harnessing their potential requires efficient and automated information extraction: they exist mainly as free-text clinical narrative, from which it is a major challenge to obtain structured data. Natural language processing (NLP) provides techniques that aid the conversion of text into a structured representation, and thus enables computers to derive meaning from human (ie, natural language) input. Used on radiology reports, NLP techniques enable automatic identification and extraction of information. By exploring the various purposes for their use, this review examines how radiology benefits from NLP. A systematic literature search identified 67 relevant publications describing NLP methods that support practical applications in radiology. This review takes a close look at the individual studies in terms of tasks (ie, the extracted information), the NLP methodology and tools used, and their application purpose and performance results. Additionally, limitations, future challenges, and requirements for advancing NLP in radiology will be discussed. (©) RSNA, 2016 Online supplemental material is available for this article.

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)

Atmospheric dispersion modeling and uncertainty analysis were carried out support the decision making in case of radiological emergency events. The risk caused by inhalation is highly dependent on air concentrations for radionuclides, therefore air monitoring and dispersion modeling have to be performed carefully to reduce the uncertainty of the health risk assessment for the public. When an intentional release of radioactive materials occurs in an urban area, air quality for radioactive materials in the environment is of great importance to take action for countermeasures and environmental risk assessments. Atmospheric modeling is part of the decision making tasks and that it is particularly important for emergency managers as they often need to take actions quickly on very inadequate information. In this study, we assume an 137 Cs explosion of 50 TBq using RDDs in the metropolitan area of Soul, South Korea. California Puff Model is used to calculate an atmospheric dispersion and transport for 137 Cs, and environmental risk analysis is performed using the Monte Carlo method

The 2016 RAD-AID Conference analyzed the accelerated global activity in the radiology community that is transforming medical imaging into an effective spearhead of health care capacity building in low- and middle-income countries. Global health efforts historically emphasized disaster response, crisis zones, and infectious disease outbreaks. However, the projected doubling of cancer and cardiovascular deaths in developing countries in the next 15 years and the need for higher technology screening and diagnostic technologies in low-resource regions, as articulated by the United Nations' new Sustainable Development Goals of 2016, is heightening the role of radiology in global health. Academic US-based radiology programs with RAD-AID chapters achieved a threefold increase in global health project offerings for trainees in the past 5 years. RAD-AID's nonprofit radiology volunteer corps continue to grow by more than 40% yearly, with a volunteer base of 5,750 radiology professionals, serving in 23 countries, donating close to 20,000 pro bono hours globally in 2016. As a high-technology specialty interfacing with nearly all medical and surgical disciplines, radiology underpins vital health technology infrastructure, such as digital imaging archives, electronic medical records, and advanced diagnosis and treatment, essential for long-term future health care capacity in underserved areas of the world.

2016-01-01

Radiology's core assets include the production, interpretation, and distribution of quality imaging studies. Second-opinion services and concierge practices in radiology aim to augment traditional services by providing patient-centered and physician-centered care, respectively. Patient centeredness enhances patients' understanding and comfort with their radiology tests and procedures and allows them to make better decisions about their health care. As the fee-for-service paradigm shifts to value-based care models, radiology practices have begun to diversify imaging service delivery and communication to coincide with the American College of Radiology Imaging 3.0 campaign. Physician-centered consultation allows for communication of evidence-based guidelines to assist referring physicians and other providers in making the most appropriate imaging or treatment decision for a specific clinical condition. There are disparate practice models and payment schema for the various second-opinion and concierge practices. This review article explores the current state and payment models of second-opinion and concierge practices in radiology. This review also includes a discussion on the benefits, roadblocks, and ethical issues that surround these novel types of practices. Copyright © 2015 Mosby, Inc. All rights reserved.

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.

The evolution of the system of radiological protection: the programme of the Nea committee on radiation protection and public health

The primary aim of radiological protection has always been to provide an appropriate standard of protection for the public and workers without unduly limiting the beneficial practices giving rise to radiation exposure. Over the past few decades, many studies concerning the effects of ionising radiation have been conducted, ranging from those that examine the effects of radiation on individual cells, to epidemiological studies that examine the effects on large populations exposed to different radiation sources. Using information gained from these studies to estimate the consequences of radiation exposure, together with the necessary social and economic judgements, the International Commission on Radiological Protection (ICRP) has put forward a series of recommendations to structure an appropriate system for radiological protection, and to ensure a high standard of protection for the public and for occupational exposed workers. The ICRP system of radiological protection that has evolved over the years now covers many diverse radiological protection issues. Emerging issues have been dealt with more or less on an individual basis resulting in an overall system, which while very comprehensive, is also complex. With such a complex system it is not surprising that some perceived inconsistencies or incoherence may lead to concerns that radiation protection issues are not being adequately addressed. Different stakeholders in decisions involving radiological protection aspects tend to focus on different elements of this perceived incoherence. To advance solutions to these issues, the OECD Nuclear Energy Agency (NEA) has been working for some time to contribute to the evolution of a new radiological protection system, through its Committee on Radiation Protection and Public Health (CRPPH). This group of senior regulators and expert practitioners has, throughout its existence, been interested in the development of recommendations by the ICRP. Recently, this interest has

For calibration laboratories, routine calibrations of instruments meeting stated accuracy goals are important. One method of achieving the accuracy goals is to establish and follow a quality assurance program designed to monitor all aspects of the calibration program and to provide the appropriate feedback mechanism if adjustments are needed. In the United States there are a number of organizations with laboratory accreditation programs. All existing accreditation programs require that the laboratory implement a quality assurance program with essentially the same elements in all of these programs. Collectively, these elements have been designated as a Measurement Quality Assurance (MQA) program. This paper will briefly discuss the interrelationship of the elements of an MQA program. Using the Center for Devices and Radiological Health (CDRH) X-ray Calibration Laboratory (XCL) as an example, it will focus on setting up a quality control program for the equipment in a Secondary Calibration Laboratory.

After having had defined the concept of research and stages of scientific method in the health field, there has been an attempt to deal with the characteristics of radiological research in the last years, as well as current and future guidelines of such. Among those items considered are the concept of teams which would be interdisciplinary and multi-centered (molecular imaging, imaging-guided therapy, early detection of illness using imaging techniques), as well as the need for certain changes in mentality. As such, there would appear a new generation of scientists (with training in molecular biology, bioengineering, physiopathology and pharmacology) who would bring to fruition an integral use of computers to complement research and imaging techniques. Finally, the concept of evidence-based radiology is analyzed, along with its principles and associated repercussions in health care and research. (Author) 15 refs

 Globalization and emigration impact on the spectrum of diseases challenging health care systems. Medical practitioners have to particularly prepare for infectious diseases.  The database of a health care center specialized on tropical medicine was screened for patients with history of migration and one of the following diagnoses: Cystic echinococcosis, tuberculosis, schistosomiasis, visceral leishmaniosis, and neurocysticercosis. Representative casuistics were prepared from select case histories. Radiological pertinent knowledge was compiled based on literature search.  A small selection of frequently imported infectious diseases covers a considerable fraction of health care problems associated with migration. For cystic echinococcosis, schistosomiasis, and neurocysticercosis imaging is the most relevant diagnostic procedure defining also disease stages. Tuberculosis and visceral leishmaniosis are important differentials for malignant diseases.  Imaging plays a meaningful role in diagnosis, treatment stratification, and follow-up of imported infectious diseases. Radiological skills concerning these diseases are important for providing health care for patients in context of migration.   · Imaging plays a meaningful role in multidisciplinary care for imported infectious diseases.. · A small selection covers a considerable fraction of infectious diseases expected in context of migration.. · Stojkovic M, Müller J, Junghanss T et al.

 Interdisciplinary radiological conferences and boards can improve therapeutic pathways. Because of the reinterpretation and presentation of external image data, which already was read, an additional workload is created which is currently not considered by health care providers. In this review we discuss the ongoing basics and possibilities in health economy for a radiological second opinion for the outpatient and inpatient sector in Germany.  Based on up-to-date literature and jurisdiction, we discuss the most important questions for the reimbursement for second opinions and conference presentations of external image data in an FAQ format. Additionally, we focus on the recently introduced E-Health law accordingly.  Radiological services considering second opinion or board presentation of externally acquired image data are currently not adequately covered by health care providers. In particular, there is no reimbursement possibility for the inpatient sector. Only patients with private insurance or privately paid second opinions can be charged when these patients visit the radiologist directly.  Currently there is no adequate reimbursement possibility for a radiological second opinion or image demonstrations in clinical conferences. It will be essential to integrate adequate reimbursement by health care providers in the near future because of the importance of radiology as an essential diagnostic and therapeutic medical partner.   · Currently there is no reimbursement for image interpretation and presentation in boards.. · Second opinions can only be reimbursed for patients with private insurance or privately recompensed.. · The E-Health law allows reimbursement for tele-counsel in very complex situations.. · It will be crucial to integrate radiological second opinion in future reimbursement policies by health care providers.. · Schreyer AG, Steinhäuser RT, Rosenberg B.

Aiming to elaborate a methodology to optimize the performance of the Radiology Service of the Military Police Hospital, in Rio dee Janeiro, some goals were established: improvement of the attendance to patients; improvement of the qualification of technicians; achievement and maintenance of high degrees of quality in each step of the radiological process; improvement of the image quality; optimization of dose per examination and cost reduction. The procedure used to detect faults in the radiological process was the analysis of causes of film losses. Results show a 70% reduction in the film rejection rate. 74% of total identified faults were due to equipment, 11% to films, 10% to patients and 5% to developing. The reduction in the cost of developed film reached 75%. A training course given to the staff of the radiological service fully reached its goals, contributing, with the staff motivation, mostly to the success of the program. This success indicates that, with a serious persistent work, it is possible to offer to patients services within their expectations, even at a public hospital. Such programs should be supported by health authorities, not only due to their technical and economic needs but, mostly, due to their social implications. (author). 10 refs., 11 figs

Education and training of medical physicists in radiology

International Nuclear Information System (INIS)

Todorov, V.; Vassileva, J.

2006-01-01

Full text: Medical radiology is chronologically the first and widest field of work of medical physicists. Therefore the education and training of medical radiological physicists is of big importance for both diagnostics and therapy. The education of medical radiological physicists in Bulgaria is organized in two levels: university and postgraduate, which is a good achievement of Bulgarian educational system. University education is in the framework of the M. Sc. program in Medical physics with a prevalent training in medical radiological physics. Three universities in the country have been carrying out this education since more than ten years. Postgraduate education covers specialties Medical Radiological Physics and Radiation Hygiene. It is organized by the Medical University but the training is opened also to specialists outside the health care system. The interests in both levels of education and training in Medical Physics is increasing with about 40 trainees in last years. The university and postgraduate education has good quality in theory but still inadequate in practical aspects. The continuous training and qualification of medical physicists has also difficulties; the main reasons are insufficient technical and financial resources as well as the lack of interest of the staff of the training centers. The responsibilities for education and training of medical physicists in radiology should be shared between physicists and physicians in the country

A virtual environment for simulation of radiological accidents

International Nuclear Information System (INIS)

Silva, Tadeu Augusto de Almeida; Farias, Oscar Luiz Monteiro de

2013-01-01

A virtual environment is a computer environment, representative of a subset of the real world, and where models of the real world entities, process and events are included in a virtual (three-dimensional) space. Virtual environments are ideal tools for simulation of certain critical processes, such as radiological accidents, where human beings or properties can suffer irreversible or long term damages. Radiological accidents are characterized by the significant exposure to radiation of specialized workers and general public. The early detection of a radiological accident and the determination of its possible extension are essential factors for the planning of prompt answers and emergency actions. This paper proposes the integration of georeferenced representation of the three-dimensional space and agent-based models, with the objective to construct virtual environments that have the capacity to simulate radiological accidents. The three-dimensional georeferenced representations of space candidates are: 1) the spatial representation of traditional geographical information systems (GIS); 2) the representation adopted by Google Maps®. Adding agents to these spatial representations allow us to simulate radiological accidents, quantify the doses received by members of the public, obtain a possible spatial distribution of people contaminated, estimate the number of contaminated individuals, estimate the impact on the health-network, estimate environmental impacts, generate exclusion zones, build alternative scenarios and train staff to deal with radiological accidents.

Adeshina, A M; Hashim, R

2017-03-01

Diagnostic radiology is a core and integral part of modern medicine, paving ways for the primary care physicians in the disease diagnoses, treatments and therapy managements. Obviously, all recent standard healthcare procedures have immensely benefitted from the contemporary information technology revolutions, apparently revolutionizing those approaches to acquiring, storing and sharing of diagnostic data for efficient and timely diagnosis of diseases. Connected health network was introduced as an alternative to the ageing traditional concept in healthcare system, improving hospital-physician connectivity and clinical collaborations. Undoubtedly, the modern medicinal approach has drastically improved healthcare but at the expense of high computational cost and possible breach of diagnosis privacy. Consequently, a number of cryptographical techniques are recently being applied to clinical applications, but the challenges of not being able to successfully encrypt both the image and the textual data persist. Furthermore, processing time of encryption-decryption of medical datasets, within a considerable lower computational cost without jeopardizing the required security strength of the encryption algorithm, still remains as an outstanding issue. This study proposes a secured radiology-diagnostic data framework for connected health network using high-performance GPU-accelerated Advanced Encryption Standard. The study was evaluated with radiology image datasets consisting of brain MR and CT datasets obtained from the department of Surgery, University of North Carolina, USA, and the Swedish National Infrastructure for Computing. Sample patients' notes from the University of North Carolina, School of medicine at Chapel Hill were also used to evaluate the framework for its strength in encrypting-decrypting textual data in the form of medical report. Significantly, the framework is not only able to accurately encrypt and decrypt medical image datasets, but it also

This review was conducted to explore the literature to determine the availability, content, and evaluation of existing chemical, biological, radiological, and nuclear (CBRN) education programs for health professionals. An integrative review of the international literature describing disaster education for CBRN (2004-2016) was conducted. The following relevant databases were searched: Proquest, Pubmed, Science Direct, Scopus, Journals @ OVID, Google Scholar, Medline, and Ichuschi ver. 5 (Japanese database for health professionals). The search terms used were: "disaster," "chemical," "biological," "radiological," "nuclear," "CBRN," "health professional education," and "method." The following Medical Subject Headings (MeSH) terms, "education," "nursing," "continuing," "disasters," "disaster planning," and "bioterrorism," were used wherever possible and appropriate. The retrieved articles were narratively analyzed according to availability, content, and method. The content was thematically analyzed to provide an overview of the core content of the training. The literature search identified 619 potentially relevant articles for this study. Duplicates (n=104) were removed and 87 articles were identified for title review. In total, 67 articles were discarded, yielding 20 articles for all-text review, following 11 studies were retained for analysis, including one Japanese study. All articles published in English were from the USA, apart from the two studies located in Japan and Sweden. The most typical content in the selected literature was CBRN theory (n=11), followed by studies based on incident command (n=8), decontamination (n=7), disaster management (n=7), triage (n=7), personal protective equipment (PPE) use (n = 5), and post-training briefing (n=3). While the CBRN training course requires the participants to gain specific skills and knowledge, proposed training courses should be effectively constructed to include approaches such as scenario-based simulations

The man's exposure to ionizing radiation in health are has increased considerably due not only the great request of medical examinations as well as the improvement of the techniques used in diagnostic imaging, for example, equipment for conventional X-rays, CT scans, mammography, hemodynamic and others. Although the benefits of using of radiology techniques are unquestionable, the lack of training in radiation protection of the workers, associated with procedure errors, have been responsible for the increasing number of radiation overexposures of these workers. Sometimes these high doses are real and there is a true radiological accident. The radiation workers, named occupationally Exposed Individual (IOE), must comply with two national regulations: Governmental Decree 453/1998 of the National Agency of Sanitary Surveillance (Portaria 453/1998 ANVISA Agencia Nacional de Vigilancia Sanitaria), which establishes the basic guidelines for radiation protection in medial and dental radiology and; the Governmental Decree NR-32/2002 of the Ministry of Labour and Employment (Ministerio do Trabalho e Emprego), which establishes the basic guidelines for the worker's health. The two mandatory regulations postulate a detailed investigation in the event of radiation overexposure of an IOE. In order to advice the diagnostic institution to perform an efficient analysis, investigation and report of high doses, it is proposed the use of a computational tool named 'Medical SisRadiologia'. This software tool enables the compilation and record of radiological abnormal data occurred in a diagnostic institution. It will also facilitate the detailed analysis of the event and will increase the effectiveness and development of work performed by the Radiation Protection Service. At the end, a technical report is issued, in accordance with the regulations of the technical regulations, which could also be used as training tool to avoid another event in the future. (author)

In this study, the activity concentrations of the natural radionuclides in phosphate rocks and its products were measured using a high- purity germanium detector (HPGe). The obtained activity results show remarkable wide variation in the radioactive contents for the different phosphate samples. The average activity concentration of "2"3"5U, "2"3"8U, "2"2"6Ra, "2"3"2Th and "4"0K was found as (45, 1031, 786, 85 and 765 Bq/kg) for phosphate rocks, (28, 1234, 457, 123 and 819 Bq/kg) for phosphate fertilizers, (47, 663, 550, 79 and 870 Bq/kg) for phosphogypsum and (25, 543, 409, 54 and 897 Bq/kg) for single super phosphate respectively. Based on the measured activities, the radiological parameters (activity concentration index, absorbed gamma dose rate in outdoor and indoor and the corresponding annual effective dose rates and total excess lifetime cancer risk) were estimated to assess the radiological hazards. The total excess lifetime cancer risk (ELCR) has been calculated and found to be high in all samples, which related to high radioactivity, representing radiological risk for the health of the population. - Highlights: • Level of radioactivity of phosphate rocks and by-products samples. • The radiological health hazard parameters. • Radiological risk to the health of the population. • The excess lifetime cancer risk factor.

Varicocele is a fairly common condition in male individuals. Although a minor disease, it may cause infertility and testicular pain. Consequently, it has high health and social impact. Here we review the current status of interventional radiology of male varicocele. We describe the radiological anatomy of gonadal veins and the clinical aspects of male varicocele, particularly the physical examination, which includes a new clinical and ultrasound Doppler maneuver. The surgical and radiological treatment options are also described with the focus on retrograde and antegrade sclerotherapy, together with our long experience with these procedures. Last, we compare the outcomes, recurrence and persistence rates, complications, procedure time and cost-effectiveness of each method. It clearly emerges from this analysis that there is a need for randomized multicentre trials designed to compare the various surgical and percutaneous techniques, all of which are aimed at occlusion of the anterior pampiniform plexus.

The content of different courses of radiological protection given in the Instituto Bailer's ( a join between the National University of Cuyo and the National Commission of Atomic Energy) guided to different groups of students or professionals are also introduced. Finally, some of the examples used in order to clarify practical situations are shown. (author)

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

Faced with the increasing exposure of the population to ionizing radiations and the need to respect users' rights, political and scientific efforts have been undertaken in order to improve image quality in radiodiagnostics and reduce risks to patients. In Brazil, in the past 20 years, a low rate of investment in this area and inadequate health policies have lead to diagnostic radiology services of poor quality. For their part, scientific societies, professional associations and the Ministry of Health have issued federal and state norms which require the control of physical parameters of the radiological equipment. Consequently, there is a need to create a National Reference Laboratory to oversee, inspect and evaluate the implementation of such norms. Another topic addressed in this article is the professional profile of the Medical Physics Specialist. (author)

Full Text Available The United States Food and Drug Administration (FDA Center for Devices and Radiological Health (CDRH is charged with ensuring patients in the US have timely access to high-quality, safe, and effective medical devices of public health importance. Within CDRH, the Division of Neurological and Physical Medicine Devices reviews medical technologies that interface with the central and peripheral nervous system (neurotechnologies, including neurointerventional medical devices that are used in the treatment of stroke. Endovascular treatments have demonstrated recent advances in reaching the marketplace and providing more options for patients with acute ischemic stroke and intracranial aneurysms specifically. Depending upon the pathway chosen for regulatory approval, and the evidentiary standard for different regulatory pathways, neurotechnologies can have well-established safety and effectiveness profiles, varying degrees of scientific and clinical uncertainty regarding safety and effectiveness, or when a humanitarian use exists, need only demonstrate a probable benefit and safety to the patient so potentially life-saving treatments can reach the marketplace. Reperfusion therapies have had specific advances in the treatment of stroke patients that originally had limited or no treatment options and for preventative treatments in providing care to patients with intracranial aneurysms to avoid potentially more catastrophic outcomes. Collaboration in multiple forums and environments will be important to continue to foster the neurointerventional technology sector and positively impact clinical medicine, from diagnosing and treating a neurological disorder, to potentially altering the progression of disease, and in many ways, contemporary approved devices have brought a new sense of hope and optimism that serious and otherwise disabling neurological diseases can be treated and in many cases cured with modern therapy. We present here the scope of FDAâ

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.

Biological effects and radiation protection in veterinary radiology: a literature review

Rosa, P.C.; Siqueira, D.; Barros, F.S.

2017-01-01

Veterinary radiology is a tool of excellent diagnostic support. Besides X--ray, it counts on technological advances such as computed tomography, nuclear medicine and interventional radiology . It is common during X-ray practice to use exposure parameters with short times to avoid blurring by the movement of the animal, but the fact that the animals need to be immobilized during the exposures contribute significantly with the increase of the dose received by the professionals, whose biological risks are not yet well established as a result of exposure to other factors harmful to health, such as anesthetic gases, insecticides, zoonoses and others. For this reason, we sought to verify the main radiological risks to which veterinarians are exposed and the best means to guarantee radiological protection

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.

Visual evaluation of chest radiograph images is the most practical and effective method. This study compared the Body Mass Index, waist circumference, and mAs with chest radiographs of 351 women. The Bureau of Radiological Health method was used to evaluate the image quality of chest X-ray images by anatomical and physical methods. The average age of the subjects was 30.17±4.73 and the average waist circumference was 66.91±4.67 cm. The mean Body Mass Index value was 20.21±2.23, the mean value of mAs was 3.04±0.78, and the mean value of Bureau of Radiological Health was 79.83±8.45. When the Body Mass Index value increased, waist circumference and mAs mean value increased. The mean value of Body Mass Index was statistically significant(p<0.05) in Group 4 compared to Groups 1 and 2, with increasing Body Mass Index. Exposure control of the automatic exposure control system is considered to be well performed according to body thickness or Body Mass Index at the time of chest radiography. As the Body Mass Index increases, the thickness of the body increases and the breast thickness of the woman also increases. Therefore, it is considered that the exposure amount is changed by the automatic exposure control device to affect the image quality

This report documents the projected radiological dose impacts associated with the disposal of radioactive low-level waste at the Radioactive Waste Management Complex at the Idaho National Engineering Laboratory. This radiological performance assessment was conducted to evaluate compliance with applicable radiological criteria of the US Department of Energy and the US Environmental Protection Agency for protection of the public and the environment. The calculations involved modeling the transport of radionuclides from buried waste, to surface soil and subsurface media, and eventually to members of the public via air, groundwater, and food chain pathways. Projections of doses were made for both offsite receptors and individuals inadvertently intruding onto the site after closure. In addition, uncertainty and sensitivity analyses were performed. The results of the analyses indicate compliance with established radiological criteria and provide reasonable assurance that public health and safety will be protected.

Data mining facilitates the study of radiology data in various dimensions. It converts large patient image and text datasets into useful information that helps in improving patient care and provides informative reports. Data mining technology analyzes data within the Radiology Information System and Hospital Information System using specialized software which assesses relationships and agreement in available information. By using similar data analysis tools, radiologists can make informed decisions and predict the future outcome of a particular imaging finding. Data, information and knowledge are the components of data mining. Classes, Clusters, Associations, Sequential patterns, Classification, Prediction and Decision tree are the various types of data mining. Data mining has the potential to make delivery of health care affordable and ensure that the best imaging practices are followed. It is a tool for academic research. Data mining is considered to be ethically neutral, however concerns regarding privacy and legality exists which need to be addressed to ensure success of data mining

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.

The medicine is the area that more it has benefited with the implementation of the radiation. However, a great number of incidents/accidents they have happened in hospitals in recent years. The above-mentioned stands out the necessity to improve the acting of the radiological safety management systems in Hospitals. This work presents a Management System of Radiological Safety (SGSR). The SGSR has as fundamental objective the one of maintaining the radiological risks inside acceptable levels. The SGSR is generic and it can be applied in the nuclear medicine, radiodiagnostic, radiotherapy, and in other areas of the health sector where it is required to prevent accidents or incidents that affect the health or the well-being of the worker or user. Also it was diagnosed a Specialties Hospital of the Mexico City using some characteristics of the SGSR. The obtained results show that the SGSR can contribute significantly in the improvement of the quality of the service in the attention to the patients and in the radiological safety. (Author)

In November 2007, the Wisconsin Division of Public Health Hospital Disaster Preparedness Program State Expert Panel on Radiation Emergencies issued a report titled The Management of Patients in a Radiological Incident. Gundersen Lutheran Health System was selected to conduct a demonstration project to implement the recommendations in that report. A comprehensive radiological incident response plan was developed and implemented in the hospital's Trauma and Emergency Center, including the purchase and installation of radiation detection and identification equipment, staff education and training, a tabletop exercise, and three mock incident test exercises. The project demonstrated that the State Expert Panel report provides a flexible template that can be implemented at community hospitals using existing staff for an approximate cost of $25,000.

Hospital management of mass radiological casualties: reassessing exposures from contaminated victims of an exploded radiological dispersal device (RDD)

Ansari, Armin; Harper, Frederick Taylor; Smith, James M.

One of the key issues in the aftermath of an exploded radiological dispersal device from a terrorist event is that of the contaminated victim and the concern among healthcare providers for the harmful exposures they may receive in treating patients, especially if the patient has not been thoroughly decontaminated. This is critically important in the event of mass casualties from a nuclear or radiological incident because of the essential rapidity of acute medical decisions and that those who have life- or limb-threatening injuries may have treatment unduly delayed by a decontamination process that may be unnecessary for protecting the health and safety of the patient or the healthcare provider. To estimate potential contamination of those exposed in a radiological dispersal device event, results were used from explosive aerosolization tests of surrogate radionuclides detonated with high explosives at the Sandia National Laboratories. Computer modeling was also used to assess radiation dose rates to surgical personnel treating patients with blast injuries who are contaminated with any of a variety of common radionuclides. It is demonstrated that exceptional but plausible cases may require special precautions by the healthcare provider, even while managing life-threatening injuries of a contaminated victim from a radiological dispersal device event.

Prober, Allen S; Mehan, William A; Bedi, Harprit S

2016-07-01

Since July 2013, the Accreditation Council for Graduate Medical Education (ACGME) has required radiology residency programs to implement a set of educational milestones to track residents' educational advancement in six core competencies, including Systems-based Practice. The healthcare economics subcompetency of Systems-based Practice has traditionally been relatively neglected, and given the new increased ACGME oversight, will specifically require greater focused attention. A multi-institutional health-care economics pilot curriculum combining didactic and practical components was implemented across five residency programs. The didactic portion included a package of online recorded presentations, reading, and testing materials developed by the American College of Radiology (ACR's) Radiology Leadership Institute. The practical component involved a series of local meetings led by program faculty with the production of a deliverable based on research of local reimbursement for a noncontrast head computed tomography. The capstone entailed the presentation of each program's deliverable during a live teleconference webcast with a Radiology Leadership Institute content expert acting as moderator and discussion leader. The pilot curriculum was well received by residents and faculty moderators, with 100% of survey respondents agreeing that the pilot met its objective of introducing how reimbursement works in American radiology in 2015 and how business terminology applies to their particular institutions. A health-care economics curriculum in the style of a Massive Open Online Course has strong potential to serve as many residency programs' method of choice in meeting the health-care economics milestones.

2010-01-01

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

The purpose of this study was to determine current trends and the mode of future development in the field of medical radiology and to promote research among the nation's radiologists by analyzing the contents of the Journal of the Korean Radiologic Society(JKRS) and Radiology. The number of articles published in JKRS each year between 1990 and 1994 was counted. The research articles in JKRS(n=740) and in Radiology(n=1748) between 1992 and 1994 were categorized according to the objective, type, topic, materials, and radiologic techniques of their contents on the basis of predetermined criteria. Domestic Masters theses(n=126) and doctoral dissertations(n=75) accepted between 1990 and 1994, and domestic materials published in international journals (n=416) between 1986 and 1994 were also categorized using the same criteria. The greatest increase in the number of articles published in JKRS was seen during 1994. The majority of these aimed to retrospectively analyse the findings of diseases while the majority of articles published in Radiology dealt prospectively with the development and/or evaluation of diagnostic methods. More variety of topics and issues was seen in Radiology than in JKRS. The number of articles of domestic materials published in international journals increased from 1986 to 1994, while the number of articles of foreign materials published in Korea was relatively stationary : A significant number of theses and dissertations dealt, mostly prospectively, with studies of pathophysiologic and/or pharmacologic mechanisms using animal models. In order to understand both current trends and the direction and mode of future developments in the field of radiology, and to be able to actively deal with challenges at the forefront of radiologic development, it is essential to review research articles published in radiology-related journals

2018-01-01

Over recent years, social media engagement has proliferated among physicians, health care systems, scientific journals, professional societies, and patients. In radiology, Twitter (Twitter Inc, San Francisco, California) has rapidly become the preferred social media engagement tool and is now an essential activity at many large radiology society meetings. Twitter offers a versatile, albeit simple, platform for anyone interested in engaging with others, regardless of title, stature, or geography. In radiology and other medical specialties, year-after-year increases in Twitter engagement before, during, and after professional society meetings continue with widespread positive feedback. This short-form messaging tool also allows users to connect and interact with high-impact individuals and organizations on an ongoing basis (rather than once a year during large meetings). Through live-polling, Twitter also has the power to gather global opinions on issues highly relevant to radiology's future, such as the Medicare Access and CHIP Reauthorization Act of 2015 (MACRA) or breast cancer screening. Also increasingly popular is "live-tweeting" of curated meeting content, which makes information from the meeting accessible to a global audience. Despite the promise of growing professional networks and enabling discussions that cross geographic boundaries, the risks of Twitter use during radiology meetings must be recognized and mitigated. These include posting of unpublished data without consent (eg, slide content captured on camera phones), propagation of misinformation, and copyright infringement. Despite these issues and with an eye towards professionalism, Twitter can nonetheless be used effectively to increase engagement among radiologists, radiology societies, and patients.

Congenital hip dislocation: Radiological screening or diagnosis?

International Nuclear Information System (INIS)

Kalifa, G.; Faure, C.

1987-01-01

Congenital hip dislocation is a perfect example of public health problems: its incidence is high 0.6, to 2% of newborns in France and an early detection allows an easy and successful treatment. The current situation in our country is not satisfactory for several reasons: - Too many children are treated without reasons because of misleading radiological pictures; - Conversely, some dislocations are discovered only at the walking age, the treatment becoming then more difficult and less effective; - Almost 300,000 radiological examinations of the hip for screening are performed each year and among them 100,000 in newborns. This is not satisfactory as it is commonly admitted now that radiological examination at birth is unreliable and frequently misleading. For all these reasons a special working group has been settled up by the General Direction of Health, including physicians of different practices, from different specialities. The conclusion of this group will be published in a special booklet and can be summarized as follows: The group recommends to perform detection of congenital hip dislocation mainly by the clinical examination. This examination may be difficult but it must be performed very early, the first day of life, repeated several times, at the end of the first week and during the first, second, and third month. Every baby in this country must undergo several clinical examinations up to one year of age

Machine Learning and Radiology

Wang, Shijun; Summers, Ronald M.

2012-01-01

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. In many applications, the performance of machine learning-based automatic detection and diagnosis systems has shown to be comparable to that of a well-trained and experienced radiologist. Technology development in machine learning and radiology will benefit from each other in the long run. Key contributions and common characteristics of machine learning techniques in radiology are discussed. We also discuss the problem of translating machine learning applications to the radiology clinical setting, including advantages and potential barriers. PMID:22465077

2000 RSNA annual oration in diagnostic radiology: The future of interventional radiology.

Science.gov (United States)

Becker, G J

2001-08-01

Origins in imaging, procedural emphasis, and dependence on innovation characterize interventional radiology, which will continue as the field of image-guided minimally invasive therapies. A steady supply of innovators will be needed. Current workforce shortages demand that this problem be addressed and in an ongoing fashion. Interventional radiology's major identity problem will require multiple corrective measures, including a name change. Diagnostic radiologists must fully embrace the concept of the dedicated interventionalist. Interspecialty turf battles will continue, especially with cardiologists and vascular surgeons. To advance the discipline, interventional radiologists must remain involved in cutting-edge therapies such as endograft repair of aortic aneurysms and carotid stent placement. As the population ages, interventionalists will experience a shift toward a greater emphasis on cancer treatment. Political agendas and public pressure will improve access to care and result in managed health care reforms. Academic centers will continue to witness a decline in time and resources available to pursue academic missions. The public outcry for accountability will result in systems changes aimed at reducing errors and process changes in the way physicians are trained, certified, and monitored. Evidence-based medicine will be the watchword of this century. Interventional radiology will maintain its role through development of methods for delivery of genes, gene products, and drugs to specific target sites; control of angiogenesis and other biologic processes; and noninvasive image-guided delivery of various forms of energy for ablation.

Assessment of nuclear medicine capabilities in responding to a radiological terrorism event. Technical memorandum

2006-09-15

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.

Medical malpractice is the primary method by which people who believe they have suffered an injury in the course of medical care seek compensation in the United States and Canada. An increasing body of research demonstrates that failure to correctly diagnose is the most common allegation made in malpractice claims against radiologists. Since the 1994 survey by the Society of Chairmen of Radiology in Children's Hospitals (SCORCH), no other published studies have specifically examined the frequency or clinical context of malpractice claims against pediatric radiologists or arising from pediatric imaging interpretation. We hypothesize that the frequency, character and outcome of malpractice claims made against pediatric radiologists differ from those seen in general radiology practice. We searched the Controlled Risk Insurance Co. (CRICO) Strategies' Comparative Benchmarking System (CBS), a private repository of approximately 350,000 open and closed medical malpractice claims in the United States, for claims related to pediatric radiology. We further queried these cases for the major allegation, the clinical environment in which the claim arose, the clinical severity of the alleged injury, indemnity paid (if payment was made), primary imaging modality involved (if applicable) and primary International Classification of Diseases, 9th revision (ICD-9) diagnosis underlying the claim. There were a total of 27,056 fully coded claims of medical malpractice in the CBS database in the 5-year period between Jan. 1, 2010, and Dec. 31, 2014. Of these, 1,472 cases (5.4%) involved patients younger than 18 years. Radiology was the primary service responsible for 71/1,472 (4.8%) pediatric cases. There were statistically significant differences in average payout for pediatric radiology claims ($314,671) compared to adult radiology claims ($174,033). The allegations were primarily diagnosis-related in 70% of pediatric radiology claims. The most common imaging modality

Full Text Available After the Fukushima Daiichi Nuclear Power Station accident in 2011, concerns about radiation exposure and decline in subjective well-being have been reported. To tackle these problems, various countermeasures in relation to radiation have been implemented. In this study, we comprehensively evaluated the effects of radiological countermeasures on subjective well-being (e.g., satisfaction with life (SWL and emotional well-being and radiation anxiety, through a questionnaire survey targeting Fukushima residents (N = 1023. Propensity scores matching was applied to evaluate significant effects of radiological countermeasures on subjective well-being and radiation anxiety. Among the radiological countermeasures, thyroid examination, whole body counter, and air dose monitoring showed the highest proportions of participation, utilization, and useful evaluation, suggesting a high degree of public attention focused on these countermeasures. The basic survey was associated with significant increases in SWL and self-rated health (SH. Thyroid examination was significantly associated with not only a reduction in radiation anxiety but also an increase of emotional stress, suggesting the importance of careful design of system and detailed communication. Food inspection was associated with deterioration in SH. Those who utilized explanatory meetings showed increases in sadness, worry, and radiation anxiety, indicating that additional attention is required of the experts and authorities involved in explanatory meetings.

Hilmes, Melissa A; Hyatt, Eddie; Penrod, Cody H; Fleming, Amy E; Singh, Sudha P

2016-03-01

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.

This paper studies 278 official reports on quality assurance in dental radiology in the context of the first revision of these dental clinics, as a result of the entry into force of the regulations establishing the duties for these types of facilities. In the results section we present a quantitative analysis of the facilities equipped with an panoramic radiology apparatus, making a special reference to the brands they have available, as well as their physical features (kV, mA, filtration) and the deviations detected in their operation. Some of their features in the process of obtaining radiological images at those facilities (film control, development time, liquid renewal) are determined, and the average dose of ionising radiation used in order to obtain the same tooth radiological image is presented. This paper shows, in a quantitative way, the characteristic features of panoramic radiology in our medium. The study is intended to be continued during the next years, which would allow the assessment of the prospective improvement in dental radiological performances as a result of the newly established regulations.

1999-01-01

Radiological assessment of sites with radioactive residues starts with the identification of potential sources. The US Army Center for Health Promotion and Preventive Medicine (USACHPPM) has developed a technical guide that summarizes sources of potential radiological exposures of both civilian and military origin. These sources include those found in the natural environment, in the nuclear fuel cycle, in medical and industrial settings, in the transportation of radioactive materials, in US Army commodities and foreign materiel, and in the use and storage of nuclear weapons. This technical guide is intended to foster awareness of radiological hazards and to provide the reader with the knowledge necessary to take the first step in radiological health risk assessment: recognition of the hazard. Furthermore, this guide can be used in conjunction with other technical guides for performing radiological surveys and field dose assessments in war or peacetime operations. (author)

Analyzing the glass ceiling effect among radiologic technologists.

Belinsky, Susan B; Blagg, James D

2011-01-01

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.

Radiological optimization is one of the basic principles in each radiation-protection system and it is a basic requirement in the safety standards for radiation protection in the European Communities. The objectives of the research, performed in this field at the Belgian Nuclear Research Centre SCK-CEN, are: (1) to implement the ALARA principles in activities with radiological consequences; (2) to develop methodologies for optimization techniques in decision-aiding; (3) to optimize radiological assessment models by validation and intercomparison; (4) to improve methods to assess in real time the radiological hazards in the environment in case of an accident; (5) to develop methods and programmes to assist decision-makers during a nuclear emergency; (6) to support the policy of radioactive waste management authorities in the field of radiation protection; (7) to investigate existing software programmes in the domain of multi criteria analysis. The main achievements for 1997 are given

Prevalence of abnormal radiological findings in health care workers with latent tuberculosis infection and correlations with T cell immune response.

2007-08-01

Full Text Available More than half of all health care workers (HCWs in high TB-incidence, low and middle income countries are latently infected with tuberculosis (TB. We determined radiological lesions in a cohort of HCWs with latent TB infection (LTBI in India, and determined their association with demographic, occupational and T-cell immune response variables.We obtained chest radiographs of HCWs who had undergone tuberculin skin test (TST and QuantiFERON-TB Gold In Tube (QFT, an interferon-gamma release assay, in a previous cross-sectional study, and were diagnosed to have LTBI because they were positive by either TST or QFT, but had no evidence of clinical disease. Two observers independently interpreted these radiographs using a standardized data form and any discordance between them resolved by a third observer. The radiological diagnostic categories (normal, suggestive of inactive TB, and suggestive of active TB were compared with results of TST, QFT assay, demographic, and occupational covariates.A total of 330 HCWs with positive TST or QFT underwent standard chest radiography. Of these 330, 113 radiographs (34.2% were finally classified as normal, 206 (62.4% had lesions suggestive of inactive TB, and 11 (3.4% had features suggestive of active TB. The mean TST indurations and interferon-gamma levels in the HCWs in these three categories were not significantly different. None of the demographic or occupational covariates was associated with prevalence of inactive TB lesions on chest radiography.In a high TB incidence setting, nearly two-thirds of HCWs with latent TB infection had abnormal radiographic findings, and these findings had no clear correlation with T cell immune responses. Further studies are needed to verify these findings and to identify the causes and prognosis of radiologic abnormalities in health care workers.

The past decades have witnessed interventional radiology in China to go from a very initial clinical practice to an important medical player in modern medicine. Recently, a friendly collaboration has been successfully established between the Chinese Interventional Radiology Sub-society and the Journal of Interventional Radiology. The Chinese Interventional Radiology Sub-society will take the full responsibility for the academic governance of the Journal of Interventional Radiology and the Journal of Interventional Radiology will formally become the sole interventional academic periodical of the Chinese Interventional Radiology Sub-society in China. This collaboration will surely make Chinese interventional radiology to initiate a new era,promote the further development of interventional radiology at home and enable the Journal of Interventional Radiology to step into the international medical circle.

Practices and regulations of radiological mass screening in the United Kingdom

International Nuclear Information System (INIS)

Abrams, M.E.

1987-01-01

The only radiological mass screening undertaken in the UK was the mass miniature radiography service for detection of tuberculosis by chest x-ray. Mass miniature radiographic (MMR) units were set up when tuberculosis was a common illness. However, by 1969 the detection rate of tuberculosis was so low that it was no longer cost-effective as a preventive health measure. In the last decade there has also been an increased awareness that people should only be exposed to radiation for medical purposes if it is judged to be clinically desirable. For some years, therefore, the Department's policy has been to discourage self-referral to these units and to advise people to consult their doctor should they be concerned about symptoms. Health authorities have been made aware of the need to continue to review the level of provision of MMR services and to integrate these facilities with hospital radiological departments as far as possible. To secure further information on the costs and benefits of radiological procedures, the Department is financially supporting research by the Royal College of Radiologists' Working Party on the Effective use of Diagnostic Radiology. Research is taking place in a number of areas and the work done on the use of preoperative chest x-ray in hospital is particularly germane

A critical review of the readability of online patient education resources from RadiologyInfo.Org.

Health consumers and their families rely on the Internet as a source of authoritative information regarding the procedures used to reach a diagnosis, effect treatment, and influence prognosis. In radiology, online materials can be a means by which to offer patients comprehensible explanations of the capabilities, the risks and rewards, and the techniques under our purview. Consequently, estimations of health literacy should take into account the reading level of the average American when composing and transmitting such information to the lay public without the mediation of a referring physician. In December 2012, patient education reports from the files of RadiologyInfo.org, a jointly sponsored website of the American College of Radiology and the Radiological Society of North America, were downloaded to assess their textual sophistication. All 138 patient education articles including the glossary were analyzed for their respective level of "readability" using the following 10 evaluative scales: Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook Grading, Coleman-Liau Index, Gunning Fog Index, New Dale-Chall scale, FORCAST, Fry graph, Raygor Readability Estimate, and New Fog Count. The 138 online patient education articles were written, on average, between the 10th and 14th grade levels, which exceeds both the American Medical Association and the National Institutes of Health recommendations that patient education resources be comprehensible to those who read no higher than the seventh grade level. Patients may accrue a greater benefit from written articles available on RadiologyInfo.org if the texts were revised to be in compliance with the National Institutes of Health and American Medical Association grade level recommendations. This could lead to a broadened appreciation of the capabilities of radiology's role in general and enhanced understanding of imaging techniques and their application to clinical practice.

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. Ionizing radiation is a confirmed human carcinogen for most organ sites. This study, therefore, was aimed to estimate lifetime cancer risk from occupational exposure among radiologic technologists that has been recruited in 2012-2013. Our findings showed a small increased cancer risk in radiologic technologists from their occupational radiation exposure in Korea. However, continuous dose monitoring and strict regulation on occupational safety at the government level should be emphasized to prevent any additional health hazards from occupational radiation exposure. Our findings showed a small increased cancer risk in radiologic technologists from their occupational radiation exposure in Korea. However, continuous dose monitoring and strict regulation on occupational safety at the government level should be emphasized to prevent any additional health hazards from occupational radiation exposure.

This paper describes the methods being employed by Westinghouse Savannah River Company (WSRC) to perform graded assessments of radiological and toxicological sabotage vulnerability at Savannah River Site (SRS) facilities. These assessments are conducted to ensure that effective measures are in place to prevent, mitigate, and respond to a potential sabotage event which may cause an airborne release of radiological/toxicological material, causing an adverse effect on the health and safety of employees, the public, and the environment. Department of Energy (DOE) Notice 5630.3A, open-quotes Protection of Departmental Facilities Against Radiological and Toxicological Sabotage,close quotes and the associated April 1993 DOE-Headquarters guidance provide the requirements and outline an eight-step process for hazardous material evaluation. The process requires the integration of information from a variety of disciplines, including safety, safeguards and security, and emergency preparedness. This paper summarizes WSRC's approach towards implementation of the DOE requirements, and explains the inter-relationships between the Radiological and Toxicological Assessments developed using this process, and facility Hazard Assessment Reports (HAs), Safety Analysis Reports (SARs), and Facility Vulnerability Assessments (VAs)

In recent publications, such as Publications 117 and 120, the Commission provided practical advice for physicians and other healthcare personnel on measures to protect their patients and themselves during interventional procedures. These measures can only be effective if they are encompassed by a framework of radiological protection elements, and by the availability of professionals with responsibilities in radiological protection. This framework includes a radiological protection programme with a strategy for exposure monitoring, protective garments, education and training, and quality assurance of the programme implementation. Professionals with responsibilities in occupational radiological protection for interventional procedures include: medical physicists; radiological protection specialists; personnel working in dosimetry services; clinical applications support personnel from the suppliers and maintenance companies; staff engaged in training, standardisation of equipment, and procedures; staff responsible for occupational health; hospital administrators responsible for providing financial support; and professional bodies and regulators. This publication addresses these elements and these audiences, and provides advice on specific issues, such as assessment of effective dose from dosimeter readings when an apron is worn, estimation of exposure of the lens of the eye (with and without protective eyewear), extremity monitoring, selection and testing of protective garments, and auditing the interventional procedures when occupational doses are unusually high or low (the latter meaning that the dosimeter may not have been worn).

RadiologyInfo.org is a public information portal designed to support patient care and broaden public awareness of the essential role radiology plays in overall patient health care. Over the past 14 years, RadiologyInfo.org has evolved considerably to provide access to more than 220 mixed-media descriptions of tests, treatments, and diseases through a spectrum of mobile and desktop platforms, social media, and downloadable documents in both English and Spanish. In 2014, the RSNA-ACR Public Information Website Committee, which stewards RadiologyInfo.org, developed 3- to 5-year strategic and implementation plans for the website. The process was informed by RadiologyInfo.org user surveys, formal stakeholder interviews, focus groups, and usability testing. Metrics were established as key performance indicators to assess progress toward the stated goals of (1) optimizing content to enhance patient-centeredness, (2) enhancing reach and engagement, and (3) maintaining sustainability. Major changes resulting from this process include a complete redesign of the website, the replacement of text-rich PowerPoint presentations with conversational videos, and the development of an affiliate network. Over the past year, visits to RadiologyInfo.org have increased by 60.27% to 1,424,523 in August 2016 from 235 countries and territories. Twenty-two organizations have affiliated with RadiologyInfo.org with new organizations being added on a monthly basis. RadiologyInfo provides a tangible demonstration of how radiologists can engage directly with the global public to educate them on the value of radiology in their health care and to allay concerns and dispel misconceptions. Regular self-assessment and responsive planning will ensure its continued growth and relevance. Copyright © 2016 American College of Radiology. Published by Elsevier Inc. All rights reserved.

Systematic Review of the Application of Lean and Six Sigma Quality Improvement Methodologies in Radiology.

Amaratunga, Thelina; Dobranowski, Julian

2016-09-01

Preventable yet clinically significant rates of medical error remain systemic, while health care spending is at a historic high. Industry-based quality improvement (QI) methodologies show potential for utility in health care and radiology because they use an empirical approach to reduce variability and improve workflow. The aim of this review was to systematically assess the literature with regard to the use and efficacy of Lean and Six Sigma (the most popular of the industrial QI methodologies) within radiology. MEDLINE, the Allied & Complementary Medicine Database, Embase Classic + Embase, Health and Psychosocial Instruments, and the Ovid HealthStar database, alongside the Cochrane Library databases, were searched on June 2015. Empirical studies in peer-reviewed journals were included if they assessed the use of Lean, Six Sigma, or Lean Six Sigma with regard to their ability to improve a variety of quality metrics in a radiology-centered clinical setting. Of the 278 articles returned, 23 studies were suitable for inclusion. Of these, 10 assessed Six Sigma, 7 assessed Lean, and 6 assessed Lean Six Sigma. The diverse range of measured outcomes can be organized into 7 common aims: cost savings, reducing appointment wait time, reducing in-department wait time, increasing patient volume, reducing cycle time, reducing defects, and increasing staff and patient safety and satisfaction. All of the included studies demonstrated improvements across a variety of outcomes. However, there were high rates of systematic bias and imprecision as per the Grading of Recommendations Assessment, Development and Evaluation guidelines. Lean and Six Sigma QI methodologies have the potential to reduce error and costs and improve quality within radiology. However, there is a pressing need to conduct high-quality studies in order to realize the true potential of these QI methodologies in health care and radiology. Recommendations on how to improve the quality of the literature are proposed

Quality assurance programme in diagnostic radiology

One hundred years after the discovery of X-rays, they continue being nowadays part of physicians' daily activities, and the diagnosis through the use of X-ray equipment is one of the most important fields in clinical medicine, thus becoming the most important cause of human exposure to artificial sources. For this reason, in the last twenty years, most of the developed countries did the utmost to establish programs which could warrant the quality of the radiographic image. Aiming the protection of human being against the harmful effects of ionizing radiations, in December 1980, World Health Organization decided to form a group of professionals highly experienced in medical radiology, and initiate an inspection and quality control program. In September 1988, the Group of Studies of the Program Related to Radiological Protection of the Commission in the European Communities, prepared a working paper in which guidelines were set up regarding quality of images, dosage to patient, and associated radiographic factors, necessary to obtain acceptable radiologic performance. In Brazil, efforts driven in this direction, guided by some equipment testing, starting in 1990, began to be more known. When the Director and the Head of Radiology in the Military Police Hospital of the State of Rio de Janeiro (HPM) reamed about these efforts, they decided to contact the Institute for Radioprotection and Dosimetry (IRD) of Comissao Nacional de Energia Nuclear and submit the problem of low radiologic performance and increasing rates of rejection. Thus, with the coincidence of interests and needs, along with a proposal from the Commission of the European Communities (CEC), IRD decided to offer the author laboratory support to elaborate a Quality Assurance Program (QAP) to be implemented in HPM.

To develop a specific RADiological Patient Safety System (RADPASS) checklist for interventional radiology and to assess the effect of this checklist on health care processes of radiological interventions. On the basis of available literature and expert opinion, a prototype checklist was developed. The checklist was adapted on the basis of observation of daily practice in a tertiary referral centre and evaluation by users. To assess the effect of RADPASS, in a series of radiological interventions, all deviations from optimal care were registered before and after implementation of the checklist. In addition, the checklist and its use were evaluated by interviewing all users. The RADPASS checklist has two parts: A (Planning and Preparation) and B (Procedure). The latter part comprises checks just before starting a procedure (B1) and checks concerning the postprocedural care immediately after completion of the procedure (B2). Two cohorts of, respectively, 94 and 101 radiological interventions were observed; the mean percentage of deviations of the optimal process per intervention decreased from 24 % before implementation to 5 % after implementation (p < 0.001). Postponements and cancellations of interventions decreased from 10 % before implementation to 0 % after implementation. Most users agreed that the checklist was user-friendly and increased patient safety awareness and efficiency. The first validated patient safety checklist for interventional radiology was developed. The use of the RADPASS checklist reduced deviations from the optimal process by three quarters and was associated with less procedure postponements.

As health care shifts toward patient-centered care, wait times have received increasing scrutiny as an important metric for patient satisfaction. Long queues form when radiology practices inefficiently service their customers, leading to customer dissatisfaction and a lower perception of value. This article describes a four-step framework for radiology practices to resolve problematic queues: (1) analyze factors contributing to queue formation; (2) improve processes to reduce service times; (3) reduce variability; (4) address the psychology of queues.

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

To analyze the current situation about the pedagogic information on radiological protection training which could be found in Internet. More than 756 web-pages have been visited in Internet about Radiological Protection in the nuclear and medical fields, providing information mainly focusing on information to the members of the public. In this search were used internet Searching Appliance (as Copernicus, Google and Scirus), using key words related with this subject (as Radiological Protection and Health Safety), getting the internet address of organizations, societies and investigation groups. Only a low percentage (less than 5 per cent) of these addresses content information on Radiological Protection for the members of the public, including information about the regulator Organizations, and which are the objectives for protection of the members of the public against ionization radiation (from the point of view of the use of the ionization radiation in the medical and nuclear field). This work attempts to propose the use of internet as a tool for informing the members of the public in matter of radiological protection, as first link in the chain of the training and education.

During the 1940s, the early stages of nuclear programmes, the assessment of the radionuclides released to the environment was first initiated for the large nuclear facilities, with emphasis placed on environmental monitoring. The radiological assessment is a quantitative process of estimating the impact on human, resulting from the releases of the radionuclides to the environment. It is a multidisciplinary subject including identification of source terms, environmental transport and dispersion, health effect evaluation and so on. This paper briefly, but comprehensively, describes the methodology for the assessment of the environmental radiological consequence, and discusses the trend of various research fields related to the subject

Jikia, D.

2009-01-01

In 1996-2002 three radiological accidents were developed in Georgia. There were some people injured in those accidents. During medical management of the injured some mistakes and errors were revealed both in diagnostics and scheme of the treatment. The goal of this article is to summarize medical management of the mentioned radiological accidents, to estimate reasons of mistakes and errors, to present the lessons drawn in result of Georgia radiological accidents. There was no clinic with specialized profile and experience. Accordingly due to having no relevant experience late diagnosis can be considered as the main error. It had direct influence on the patients' health and results of treatment. Lessons to be drawn after analyzing Georgian radiological accidents: 1. informing medical staff about radiological injuries (pathogenesis, types, symptoms, clinical course, principles of treatment and etc.); 2. organization of training and meetings in non-specialized clinics or medical institutions for medical staff; 3. preparation of informational booklets and guidelines.(author)

A model to determine payments associated with radiology procedures.

Across the United States, there is a growing number of patients in Accountable Care Organizations and under risk contracts with commercial insurance. This is due to proliferation of new value-based payment models and care delivery reform efforts. In this context, the business model of radiology within a hospital or health system context is shifting from a primary profit-center to a cost-center with a goal of cost savings. Radiology departments need to increasingly understand how the transactional nature of the business relates to financial rewards. The main challenge with current reporting systems is that the information is presented only at an aggregated level, and often not broken down further, for instance, by type of exam. As such, the primary objective of this research is to provide better visibility into payments associated with individual radiology procedures in order to better calibrate expense/capital structure of the imaging enterprise to the actual revenue or value-add to the organization it belongs to. We propose a methodology that can be used to determine technical payments at a procedure level. We use a proportion based model to allocate payments to individual radiology procedures based on total charges (which also includes non-radiology related charges). Using a production dataset containing 424,250 radiology exams we calculated the overall average technical charge for Radiology to be $873.08 per procedure and the corresponding average payment to be $326.43 (range: $48.27 for XR and $2750.11 for PET/CT) resulting in an average payment percentage of 37.39% across all exams. We describe how charges associated with a procedure can be used to approximate technical payments at a more granular level with a focus on Radiology. The methodology is generalizable to approximate payment for other services as well. Understanding payments associated with each procedure can be useful during strategic practice planning. Charge-to-total charge ratio can be used to

International Perspectives on Radiology in Preventive Screening.

2016-11-01

Several years ago, the International Economics Committee of the ACR began a study of comparisons among nations regarding the practice of radiology. This article is the second in a series. The purpose here is to compare the use across countries of imaging modalities in the screening algorithms of a variety of common diseases. In conjunction with the initial study, this will allow radiologists to understand in greater detail how health system practices differ among a selected set of nations. In this study, a standardized survey was administered to committee members from 10 countries in the developed and developing world. As with the prior study, there were both striking differences and similarities, even among a small cohort of nations that are all (except India) members of the Organisation for Economic Co-operation and Development. For example, breast cancer screening with mammography involves similar radiographic techniques for screening evaluations and has similarly high levels of insurance coverage, but the recommended ages at initial screening and end of screening differ. Other diseases, such as lung cancer and abdominal aortic aneurysm, have variable, but overall lower, levels of estimated participation among surveyed countries and significantly lower insurance coverage. Although this data set relies on survey data from individual practitioners, it provides an important perspective of the role of radiology in screening programs. Given the increasing pressure from domestic and foreign governments to reign in health care costs, the comparative differences in screening programs, and especially their use of (often costly) imaging techniques, may be a harbinger for future health policy decisions in the United States and abroad.

Routine use of radiologic investigations WHO recommendations

International Nuclear Information System (INIS)

Racoveanu, N.T.

1987-01-01

The concern for unjustified radiological investigations started in the early fifties when medical irradiation was recognized to be the major source of population exposure to man-made ionizing radiations. This continues to be of major concern to many national and international bodies when analyzing the data on x-ray investigations and attempting to develop measures to limit their use. The Commission of European Communities (CEC) has also been motivated by the same approach - the decrease of the population dose commitment - in the studies made on radiological mass screening within the Member States of the European Community presented at a Technical Workshop held on 4-5 December 1985 in Luxembourg. Although such an approach seems to be appealing to a very large number of people sensitive to the potential hazards represented by ionizing radiations for exposed individuals and their offspring, a number of other factors, with more direct implications for the health authorities, have been recognized in the last 10-15 years as major reasons for limiting the use of radiologic procedures. As such factors are fully recognized and endorsed by WHO policy, and expressed in WHO Technical Reports Nos 689 and 723, this presentation will take into consideration these factors and not the problem of patient and population protection, which is directly implied when the radiologic investigations are limited only to those clinically justified

Purpose  Scope and clinical importance of interventional radiology markedly evolved over the last decades. Consequently it was acknowledged as independent subspecialty by the "European Union of Medical Specialists" (UEMS). Based on radiological imaging techniques Interventional Radiology is an integral part of Radiology. Materials und Methods  In 2009 the German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a structured training in Interventional Radiology. In cooperation with the German Society of Neuroradiology (DGNR) this training was extended to also cover Interventional Neuroradiology in 2012. Tailored for this training in Interventional Radiology a structured curriculum was developed, covering the scope of this modular training. Results  The curriculum is based on the DeGIR/DGNR modular training concept in Interventional Radiology. There is also an European Curriculum and Syllabus for Interventional Radiology developed by the "Cardiovascular and Interventional Radiological Society of Europe" (CIRSE). The presented curriculum in Interventional Radiology is designed to provide a uniform base for the training in Interventional Radiology in Germany, based on the competencies obtained during residency. Conclusion  This curriculum can be used as a basis for training in Interventional Radiology by all training sites. Key Points: · Interventional Radiology is an integral part of clinical radiology. · The German Society for Interventional Radiology and minimally-invasive therapy (DeGIR) developed a curriculum in Interventional Radiology. · This curriculum is an integrative basis for the training in interventional.

Depleted uranium residual radiological risk assessment for Kosovo sites

International Nuclear Information System (INIS)

Durante, Marco; Pugliese, Mariagabriella

2003-01-01

During the recent conflict in Yugoslavia, depleted uranium rounds were employed and were left in the battlefield. Health concern is related to the risk arising from contamination of areas in Kosovo with depleted uranium penetrators and dust. Although chemical toxicity is the most significant health risk related to uranium, radiation exposure has been allegedly related to cancers among veterans of the Balkan conflict. Uranium munitions are considered to be a source of radiological contamination of the environment. Based on measurements and estimates from the recent Balkan Task Force UNEP mission in Kosovo, we have estimated effective doses to resident populations using a well-established food-web mathematical model (RESRAD code). The UNEP mission did not find any evidence of widespread contamination in Kosovo. Rather than the actual measurements, we elected to use a desk assessment scenario (Reference Case) proposed by the UNEP group as the source term for computer simulations. Specific applications to two Kosovo sites (Planeja village and Vranovac hill) are described. Results of the simulations suggest that radiation doses from water-independent pathways are negligible (annual doses below 30 μSv). A small radiological risk is expected from contamination of the groundwater in conditions of effective leaching and low distribution coefficient of uranium metal. Under the assumptions of the Reference Case, significant radiological doses (>1 mSv/year) might be achieved after many years from the conflict through water-dependent pathways. Even in this worst-case scenario, DU radiological risk would be far overshadowed by its chemical toxicity

Precision Radiology Residency Training: Special Distinction Tracks for Noninterpretative Professional Development.

Snyder, Elizabeth; Solnes, Lilja; Horton, Karen M; Johnson, Pamela T

2018-06-01

The role of a radiologist has expanded beyond the tripartite mission of patient care, education, and research to include cross-specialty consultation for patient management, innovative solutions to improve health-care quality and safety, device design, and policy advocacy. As such, radiology residency programs should incorporate formalized training to prepare residents for these various professional roles. Since the 2015-2016 academic year, five training tracks focused on noninterpretative skills have been integrated into our residency training program: Clinician Educator, Quality Improvement, Entrepreneurship/Innovation, Health Policy Advocacy, and High-Value Care. Each track is longitudinal, with a set of requirements throughout the residents' training necessary to achieve certification at graduation. To date nine residents have participated in the programs, including two who received distinction in two separate tracks. Residents in each of the tracks have implemented successful initiatives related to the focus area. As such, these tracks enrich training by ensuring that residents make meaningful contributions to the department and institution during their training and disseminate successful initiatives through presentation at national meetings and publications. The duration of a radiology residency and resources available in an academic center provide opportunities for residency program directors to advance residents' skills in important noninterpretative components of radiology practice. Regardless of whether residents pursue academic medicine or private practice, these skills are necessary for graduates to become valuable members of a radiology practice and serve as national leaders in the field of radiology.

A contribution to raise awareness on ethical problems related to radiological protection in future health physicists

International Nuclear Information System (INIS)

Cantone, M.C.; Birattari, C.; Merzagora, M.

2006-01-01

It is widely accepted that Radiological Protection has a real social dimension and it is not restricted to the pure scientific and quantitative aspects. The quality in radiation protection is not reached by simply complying with current technical standards or by enforcing an improved or restricted regulation, but must also be pursued by promoting a culture of radiation protection. An effective dissemination of a radiation protection culture has to include education and training for those students who will become researchers in the involved fields, or who will be called in risk management and, as protection managers, will be asked to inform and train workers or to communicate with the public. Today, in most universities the education in ethics is a significant part of the training in medical, biological and biotechnological curricula but, it is still of poor consideration in those curricula which are traditionally related to Physical Science and even in those areas, like Health Physics, where implementation of interdisciplinary approaches and methodologies are important sources for progress. Moreover, recent advances in the research field of risk perception and communication are very rarely included in those courses. At the Health Physics post-graduate School of Milano State University, within the course of Radiation Protection, a new subject has been recently introduced facing the question of ethical problems and risk perception in radiation protection, and dealing with the activity of international organisations aimed to establish ethical principles for protection against ionising radiation. By referring to this context, students realize how the analysis of radiological risk includes both technological and ethical aspects. The hope is that a new generation of experts in heath physics will promote a dynamic development of knowledge and a higher degree of awareness even in ethical aspects within the academic, institutional or professional fields of radiation

Quality Control in Diagnostic Radiology in the Netherlands (invited paper)

International Nuclear Information System (INIS)

Zoetelief, J.

1998-01-01

Application of the general principles of radiation protection to medical diagnostic radiology implies that each procedure using X rays or radionuclides is to be justified and optimised. Optimisation in diagnostic radiology implies that the radiation burden to the patient should be as low as possible, but compatible with the image quality necessary to obtain an adequate diagnosis or to guide treatment. Quality control of equipment is a prerequisite for achieving optimisation in diagnostic radiology. This was especially recognised for mammography as employed for breast cancer screening. Existing legislation in the Netherlands includes only a few criteria for equipment used in diagnostic radiology. In addition, the criteria are not all operational and measurement methods are lacking. Therefore, upon the initiative of the Dutch Ministry of Health, Welfare and Sports, the relevant professional societies, in collaboration with the former TNO Centre for Radiological Protection and Dosimetry, formulated eleven guidelines for quality control of equipment used in diagnostic radiology, including test procedures, test frequencies and limiting values. The implementation of quality control of equipment was included in the 1984 European Directive (84/466/Euratom) laying down basic measures for the radiation protection of persons undergoing medical examination or treatment. In the most recent European Directive on medical exposure (97/43/Euratom) the importance of quality control is stressed. In addition, the latter EC directive proposes the use of diagnostic reference levels for limiting the risks for patients undergoing diagnostic radiology. In the Netherlands preliminary reference levels for various procedures employed in diagnostic radiology are suggested. Finally, methods applied in the Netherlands for assessment of image quality are discussed. (author)

Practice and regulations of radiological mass screening in Italy

International Nuclear Information System (INIS)

Indovina, P.L.; Romagnoli, S.; Paganini Fioratti, M.

1987-01-01

The law setting up the National Health Service in Italy came into force in 1978. This law attributes many public health responsibilities to local government bodies, and these have also power to issue decrees and circulars with regulatory effect. It therefore proved difficult to obtain a complete picture of the regulations in the short time available. However, those laws, decrees and circulars have been traced which impose radiological examinations on individual members of the population as a condition of their carrying out particular activities in work or study. The statistical data on the total number of persons subjected to such examinations each year have been supplied by the Central Institute of Statistics (ISTAT). In some cases it has not been possible to trace any up-to-date statistics. We have understood the term 'mass radiological screening' in a rather wide sense, not as solely mass examination prescribed on the basis of specific regulations. It is for this reason that we have included in the analyses the scoliosis examinations advised by the authorities concerned in only some areas of Italy. For the same reason radiological examination of the dental apparatus has also been taken into consideration, since it is widespread among the population even though there are no regulations on the subject

Radiological diagnostics in hyperparathyroidism

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

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.

This study aims to assess the adequacy level of radiological protection systems available in the diagnostic radiology facilities located in three capital cities of North East (NE) India. It further attempts to understand, using a multi-disciplinary approach, how the safety codes/standards in diagnostic radiology framed by the Atomic Energy Regulatory Board (AERB) and the International Atomic Energy Agency (IAEA) to achieve adequate radiological protection in facilities, have been perceived, conceptualized, and applied accordingly in these facilities. About 30 diagnostic radiology facilities were randomly selected from three capitals of states in NE India; namely Imphal (Manipur), Shillong (Meghalaya) and Guwahati (Assam). A semi-structured questionnaire developed based on a multi-disciplinary approach was used for this study. It was observed that radiological practices undertaken in these facilities were not exactly in line with safety codes/standards in diagnostic radiology of the AERB and the IAEA. About 50% of the facilities had registered/licensed x-ray equipment with the AERB. More than 80% of the workers did not use radiation protective devices, although these devices were available in the facilities. About 85% of facilities had no institutional risk management system. About 70% of the facilities did not carry out periodic quality assurance testing of their x-ray equipment or surveys of radiation leakage around the x-ray room, and did not display radiation safety indicators in the x-ray rooms. Workers in these facilities exhibited low risk perception about the risks associated with these practices. The majority of diagnostic radiology facilities in NE India did not comply with the radiological safety codes/standards framed by the AERB and IAEA. The study found inadequate levels of radiological protection systems in the majority of facilities. This study suggests a need to establish firm measures that comply with the radiological safety codes/standards of the

The discovery of X-ray was a great achievement for humanity, especially for the medical community. In Intensive Care Units (ICUs), the RX tests, performed with mobile devices, add immense value to the diagnosis of inpatients who do not have the option to carry them out of bed. Following the technology and its improvements, fatalities arose from misuse of ionizing radiation, which mostly gave up for lack of knowledge of the biological effects caused by them, which leads to fear among professionals and often prevents a quick job and effectively by professionals of radiological techniques. The research it is a systematic review of the literature and justified by the scarcity of materials that reflect on the radiological protection in ICUs. For this study we found the Virtual Health Library (VHL) and Pubmed were indexed terms radiological protection and intensive care units, the search in Portuguese and English terms were used radiological protection and intensive care unit. The study aims to inform professionals of ICUs on the main aspects that refer to X-rays in hospital beds, the standards of radiological protection and personal protective equipment, thus avoiding possible damage to the biological health of workers, addressing subjects in rules and laws about the X radiation, emphasizing the protection of professionals in intensive care. It is clear, finally, that little research is conducted in the context of radiological protection of workers ICU's and this is a place that receives daily RX equipment, deserving more attention to protect the worker.

ESR concept paper on value-based radiology.

Science.gov (United States)

2017-10-01

The European Society of Radiology (ESR) established a Working Group on Value-Based Imaging (VBI WG) in August 2016 in response to developments in European healthcare systems in general, and the trend within radiology to move from volume- to value-based practice in particular. The value-based healthcare (VBH) concept defines "value" as health outcomes achieved for patients relative to the costs of achieving them. Within this framework, value measurements start at the beginning of therapy; the whole diagnostic process is disregarded, and is considered only if it is the cause of errors or complications. Making the case for a new, multidisciplinary organisation of healthcare delivery centred on the patient, this paper establishes the diagnosis of disease as a first outcome in the interrelated activities of the healthcare chain. Metrics are proposed for measuring the quality of radiologists' diagnoses and the various ways in which radiologists provide value to patients, other medical specialists and healthcare systems at large. The ESR strongly believes value-based radiology (VBR) is a necessary complement to existing VBH concepts. The Society is determined to establish a holistic VBR programme to help European radiologists deal with changes in the evolution from volume- to value-based evaluation of radiological activities. Main Messages • Value-based healthcare defines value as patient's outcome over costs. • The VBH framework disregards the diagnosis as an outcome. • VBH considers diagnosis only if wrong or a cause of complications. • A correct diagnosis is the first outcome that matters to patients. • Metrics to measure radiologists' impacts on patient outcomes are key. • The value provided by radiology is multifaceted, going beyond exam volumes.

Pediatric radiology

1997-01-01

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

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

2017-10-01

The Fukushima Daiichi nuclear power plant accident in March 2011 shook the radiological protection world. All major organisations in the radiological protection field turned their eyes to Japan. Their actions, driven by their mandates, are reflected in their respective landmark reports on the accident. Reports of the International Commission on Radiological Protection, World Health Organisation, United Nations Scientific Committee on the Effects of Atomic Radiation, and International Atomic Energy Agency are summarised. Collaboration between key international organisations is strong, based in part on informal interactions which need to be backed up with formal relations to ensure solid long-term collaboration.

Breastfeeding is a well-recognised investment in the health of the mother-infant dyad. Nevertheless, many professionals still advise breastfeeding mothers to temporarily discontinue breastfeeding after contrast media imaging. Therefore, we performed this review to provide health professionals with basic knowledge and skills for appropriate use of contrast media. A joint working group of the Italian Society of Radiology (SIRM), Italian Society of Paediatrics (SIP), Italian Society of Neonatology (SIN) and Task Force on Breastfeeding, Ministry of Health, Italy prepared a review of the relevant medical literature on the safety profile of contrast media for the nursing infant/child. Breastfeeding is safe for the nursing infant of any post-conceptional age after administration of the majority of radiological contrast media to the mother; only gadolinium-based agents considered at high risk of nephrogenic systemic fibrosis (gadopentetate dimeglumine, gadodiamide, gadoversetamide) should be avoided in the breastfeeding woman as a precaution; there is no need to temporarily discontinue breastfeeding or to express and discard breast milk following the administration of contrast media assessed as compatible with breastfeeding. Breastfeeding women should receive unambiguous professional advice and clear encouragement to continue breastfeeding after imaging with the compatible contrast media. • Breastfeeding is a well-known investment in the health of the mother-infant dyad. • Breastfeeding is safe after administration of contrast media to the mother. • There is no need to temporarily discontinue breastfeeding following administration of contrast media.

1987-01-01

The Radiological Baseline Program (RBP) at the Waste Isolation Pilot Plant (WIPP) has been implemented to characterize the radiological conditions at the site prior to receipt of radioactive wastes. Because southeastern New Mexico was the site of an underground nuclear test in 1961, various sampling programs have intermittently monitored background and elevated radiation levels in the vicinity of the WIPP. In addition, radiological characterization of the site region was performed during the 1970's in support of the WIPP Environmental Impact Statement. The historical data are drawn primarily from monitoring activities of the US Public Health Service (PHS), the Environmental Protection Agency (EPA), US Geological Survey (USGS) and Sandia National Laboratories, Albuquerque (SNLA). Information on air and water quality, meat, milk, biota and vegetation is included in the report. This survey is intended to provide a source of reference for historical data on radiological conditions in the vicinity of the WIPP site prior to the establishment of a systematic Radiological Baseline Program. 31 refs., 1 fig

Manual for first responders to a radiological emergency. Emergency preparedness and response

International Nuclear Information System (INIS)

2008-01-01

Under Article 5.a(ii) of the Convention on Assistance in the Case of a Nuclear Accident or Radiological Emergency (Assistance Convention), one function of the IAEA is to collect and disseminate to States Parties and Member States information concerning methodologies, techniques and results of research relating to response to nuclear or radiological emergencies. As stated in IAEA Safety Standards Series No. GS-R-2 'Preparedness and Response for a Nuclear or Radiological Emergency', which establishes the requirements for an adequate level of preparedness for and response to a nuclear or radiological emergency in any State, 'first responders shall take all practicable and appropriate actions to minimize the consequences of a nuclear or radiological emergency'. The IAEA General Conference, in resolution GC(49)/RES/9, continues to encourage Member States 'to adopt the relevant Agency standards, procedures and practical tools' and underlines 'the need for first responders to have appropriate training for dealing with ionizing radiation during nuclear and radiological emergencies'. This publication is intended to assist in meeting these requirements and to fulfil Article 5 of the Assistance Convention. Its aim is to provide practical guidance for those who will respond during the first few hours to a radiological emergency (referred to here as 'first responders') and for national officials who would support this early response. It provides guidance in the form of action guides, instructions, and supporting data that can be easily applied by a State to build a basic capability to respond to a radiological emergency. This guidance should be adapted to fit the user State's organizational arrangements, language, terminology, concept of operation and capabilities. This report, published as part of the IAEA Emergency Preparedness and Response Series, replaces and builds on IAEA-TECDOC-1162 in the area of early response and first responders' actions. It takes account of the

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

Radiological interpretation: The 'step-child' in radiology

1981-01-01

Radiology has a highly developed technique, an extensive scientific literature and is excellent for acquiring information; one must contrast with this the difficulties in interpreting the information. In an attempt to find the reason for this, the process of radiological interpretation has been scrutinised. Critical consideration has been given to errors in the interpretation of the findings and to problems arising from the use of the available data. An attempt is made, with the help of diagrams, to determine a pathway for further development of information handling in X-ray diagnosis. (orig.) [de

Rational use of diagnostic radiology

Racoveanu, N.T.; Volodin, V.

1992-01-01

The escalating number of radiodiagnostic investigations has, as a consequence, an increase in medical irradiation of patients and of cost of radiological services. Radiologists in USA and UK have since early 1970 questioned the efficacy of various radiological investigations and produced substantial evidence that more rational approaches are necessary. WHO initiated, in 1977, a programme in this direction which has issued four technical reports which give practical recommendations on how to rationalize the use of radiological examinations. Three main directions are considered: (1) Abandonment of routine radiological examinations, as procedures with no clinical or epidemiologic significance and which represent a waste of resources and patient dose. (2) Patient selection for various radiological investigations based on clinical criteria (high, intermediate, low yield). Selected patients have an increased prevalence of the given disease and the predictive value of radiological investigation is much higher. (3) Use of diagnostic algorithms with higher cost/efficiency and risk/benefit ratios, improving the outcome of radiological examinations

Massive radiological releases profoundly differ from controlled releases

Pascucci-Cahen, Ludivine; Patrick, Momal

2013-01-01

In this article, the authors report identification and assessment of different types of costs associated with nuclear accidents. They first outline that these cost assessments must be as exhaustive or comprehensive as possible. While referring to past accidents, they define the different categories of costs: on-site costs (decontamination and dismantling, electricity not produced on the site), off-site costs (health costs, psychological costs, farming losses), image-related costs (impact on food and farm product exports, decrease of other exports), costs related to energy production, costs related to contaminated areas (refugees, lands). They give an assessment of a severe nuclear accident (i.e. an accident with important but controlled radiological releases) in France and outline that it would be a national catastrophe which could be however managed. They discuss the possible variations of the estimated costs. Then, they show that a major accident (i.e. an accident with massive radiological releases) in France would be an unmanageable European catastrophe because of the radiological consequences, of high economic costs, and of huge losses

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

Every radiation employees suffers radiation exposure risk while doing his job. It is important therefore to investigate the occupational health and safety of radiation employees on its relationship with the design and measurement of radiation exposure rates at an X-ray diagnostic radiological unit in this work, a case study was held on the radiological unit at BP-4 Yogyakarta for patient diagnostics, This research armed to investigate the relationship between the design of radiological unit for X-ray diagnostics and the location of the X-ray machine, based on the distance variable and radiation exposure rate during patient diagnostics. This was performed using radiological unit design data for X-ray diagnostics and the measurement of radiation exposure rates throughout patient diagnostics. The design data can then be used for determining the requirement of primary and secondary shielding materials for radiological unit as well as a calculation basis of radiation exposure rates during patient diagnostics. From the result of the research, it can be concluded that from the occupational health and safety point of view, radiation exposure around the X-ray machines are fairly good, both for the shielding materials in each X-ray room and the radiation exposures received by the workers, because they are far beyond the maximum permittable average limit (16.67 m R/days).

The US Federal Radiological Emergency Response Plan (FRERP) provides the framework for integrating the various Federal agencies responding to a major radiological emergency. The FRERP authorizes the creation of the Federal Radiological Monitoring and Assessment Center (FRMAC), which is established to coordinate all Federal agencies involved in the monitoring and assessment of the off-site radiological conditions in support of the impacted State(s) and the Lead Federal Agency (LFA). Within the FRMAC, the Monitoring and Analysis Division (M ampersand A) is responsible for coordinating all FRMAC assets involved in conducting a comprehensive program of environmental monitoring, sampling, radioanalysis, and quality assurance. To assure consistency, completeness, and the quality of the data produced, a methodology and procedures manual is being developed. This paper discusses the structure, assets, and operations of the FRMAC M ampersand A and the content and preparation of the manual

Full text: Introduction: The present work shows the development of a radiation remote monitoring system which control radiological areas in the principal facilities at CCHEN and the development in the last years to use this system called SMARR (Remote Radiological Area Monitoring System). This is an important issue in radiological safety is to know 'on line' and in a 'continuously way' the radiological variables of areas, especially if in these areas people manage radioactive sources or material, the monitoring system are operative on La Reina and Lo Aguirre Nuclear Centers. This 'knowledge' gets a good support to the radiological safety to safeguard the environment and people in the facilities. Nuclear Chilean Commission: Actually, this system is daily operating to register the background radiation and level operation, for example of the facilities research reactor, cyclone, irradiators, in order to probe the behaviors under operational requirements. The system was made using common Geiger Muller and NaI detectors. This signal is received, data by data, for a collector computer which uses a Labview program to do this displayed on a screen computer using graphics to show the activity on a radiological area, and when the lectures pass a setting value automatically the system send by e-mail and text message which also can be received for cell phones enabled for this for the supervisor. Each monitored facility is completely independent of each other and store a data backup, also every installation are monitoring with server computer, it's concentrating the information and allow to view it on line in real time, trough the intranet and internet network. In addition, the information is stored in the special report in the server and available for to do a statistics and identify the operation periods, and control of radioactive sources. The Industry: The radiological protection on industry is necessary today, the typical instrumentation on the industry is growing up in the

This report is the third in a series concerned with the annual genetically significant dose to the population of Great Britain from diagnostic radiology. It combines information from a frequency survey of diagnostic radiological examinations carried out in Great Britain in 1977 and estimates of gonadal doses for different examination types, together with population and child expectancy data. The annual genetically significant dose from diagnostic radiology carried out in Great Britain in 1977, is estimated to 118 μGy (11.8 millirad) of which 113 μGy (11.3 millirad) is contributed by diagnostic radiology carried out in National Health Service hospitals. There has been a sharp fall in the contribution from obstetric examinations since 1957 when the last national survey was carried out. The contribution from most other examination types is broadly similar and there is little evidence of a change in the overall level of genetically significant dose. This is in spite of an increase in the frequency of radiological examinations per thousand of the population of about 50 per cent. No significant differences were found as between England, Scotland and Wales. The British figure compares favourably with the levels of GSD reported from other countries with developed radiological services. (author)

The radiological assessment system for consequence analysis - RASCAL

Sjoreen, A.L.; Ramsdell, J.V.; Athey, G.F.

1996-01-01

The Radiological Assessment System for Consequence Analysis, Version 2.1 (RASCAL 2.1) has been developed for use during a response to radiological emergencies. The model estimates doses for comparison with U.S. Environmental Protection Agency (EPA) Protective Action Guides (PAGs) and thresholds for acute health effects. RASCAL was designed to be used by U.S. Nuclear Regulatory Commission (NRC) personnel who report to the site of a nuclear accident to conduct an independent evaluation of dose and consequence projections and personnel who conduct training and drills on emergency responses. It allows consideration of the dominant aspects of the source term, transport, dose, and consequences. RASCAL consists of three computational tools: ST-DOSE, FM-DOSE, and DECAY. ST-DOSE computes source term, atmospheric transport, and dose to man from accidental airborne releases of radionuclides. The source-term calculations are appropriate for accidents at U.S. power reactors. FM-DOSE computes doses from environmental concentrations of radionuclides in the air and on the ground. DECAY computes radiological decay and daughter in-growth. RASCAL 2.1 is a DOS application that can be run under Windows 3.1 and 95. RASCAL has been the starting point for other accident consequence models, notably INTERRAS, an international version of RASCAL, and HASCAL, an expansion of RASCAL that will model radiological, biological, and chemical accidents

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.

Stites, Mark; Pianykh, Oleg S

2016-04-01

Despite the long history of digital radiology, one of its most critical aspects--information security--still remains extremely underdeveloped and poorly standardized. To study the current state of radiology security, we explored the worldwide security of medical image archives. Using the DICOM data-transmitting standard, we implemented a highly parallel application to scan the entire World Wide Web of networked computers and devices, locating open and unprotected radiology servers. We used only legal and radiology-compliant tools. Our security-probing application initiated a standard DICOM handshake to remote computer or device addresses, and then assessed their security posture on the basis of handshake replies. The scan discovered a total of 2774 unprotected radiology or DICOM servers worldwide. Of those, 719 were fully open to patient data communications. Geolocation was used to analyze and rank our findings according to country utilization. As a result, we built maps and world ranking of clinical security, suggesting that even the most radiology-advanced countries have hospitals with serious security gaps. Despite more than two decades of active development and implementation, our radiology data still remains insecure. The results provided should be applied to raise awareness and begin an earnest dialogue toward elimination of the problem. The application we designed and the novel scanning approach we developed can be used to identify security breaches and to eliminate them before they are compromised.

The total value equation: a suggested framework for understanding value creation in diagnostic radiology.

Heller, Richard E

2014-01-01

As a result of macroeconomic forces necessitating fundamental changes in health care delivery systems, value has become a popular term in the medical industry. Much has been written recently about the idea of value as it relates to health care services in general and the practice of radiology in particular. Of course, cost, value, and cost-effectiveness are not new topics of conversation in radiology. Not only is value one of the most frequently used and complex words in management, entire classes in business school are taught around the concept of understanding and maximizing value. But what is value, and when speaking of value creation strategies, what is it exactly that is meant? For the leader of a radiology department, either private or academic, value creation is a core function. This article provides a deeper examination of what value is, what drives value creation, and how practices and departments can evaluate their own value creation efficiencies. An equation, referred to as the Total Value Equation, is presented as a framework to assess value creation activities and strategies. Copyright © 2014 American College of Radiology.

Estimates of radiological risk from depleted uranium weapons in war scenarios.

Science.gov (United States)

Durante, Marco; Pugliese, Mariagabriella

2002-01-01

Several weapons used during the recent conflict in Yugoslavia contain depleted uranium, including missiles and armor-piercing incendiary rounds. Health concern is related to the use of these weapons, because of the heavy-metal toxicity and radioactivity of uranium. Although chemical toxicity is considered the more important source of health risk related to uranium, radiation exposure has been allegedly related to cancers among veterans of the Balkan conflict, and uranium munitions are a possible source of contamination in the environment. Actual measurements of radioactive contamination are needed to assess the risk. In this paper, a computer simulation is proposed to estimate radiological risk related to different exposure scenarios. Dose caused by inhalation of radioactive aerosols and ground contamination induced by Tomahawk missile impact are simulated using a Gaussian plume model (HOTSPOT code). Environmental contamination and committed dose to the population resident in contaminated areas are predicted by a food-web model (RESRAD code). Small values of committed effective dose equivalent appear to be associated with missile impacts (50-y CEDE radiological risk. These computer simulations suggest that little radiological risk is associated to the use of depleted uranium weapons.

A standardized approach for determining radiological sabotage targets

International Nuclear Information System (INIS)

Gardner, B.H.; Snell, M.K.

1993-01-01

The US Department of Energy has required radiological sabotage vulnerability assessments to be conducted for years. However, the exact methodology to be used in this type of analysis still remains somewhat elusive. Therefore, there is tremendous variation in the methodologies and assumptions used to determine release levels and doses potentially affecting the health and safety of the public. In some cases, there are three orders of magnitude difference in results for dispersal of similar materials under similar meteorological conditions. To address this issue, the authors have developed an approach to standardizing radiological sabotage target analysis that starts by addressing basic assumptions and then directs the user to some recommended computerized analytical tools. Results from different dispersal codes are also compared in this analysis

The United States Federal Radiological Emergency Response Plan (FRERP) provides the framework for integrating the various Federal agencies responding to a major radiological emergency. Following a major radiological incident the FRERP authorizes the creation of the Federal Radiological Monitoring and Assessment Center (FRMAC). The FRMAC is established to coordinate all Federal agencies involved in the monitoring and assessment of the off-site radiological conditions in support of the impacted states and the Lead Federal Agency (LFA). Within the FRMAC, the Monitoring and Analysis Division is responsible for coordinating all FRMAC assets involved in conducting a comprehensive program of environmental monitoring, sampling, radioanalysis and quality assurance. This program includes: (1) Aerial Radiological Monitoring - Fixed Wing and Helicopter, (2) Field Monitoring and Sampling, (3) Radioanalysis - Mobile and Fixed Laboratories, (4) Radiation Detection Instrumentation - Calibration and Maintenance, (5) Environmental Dosimetry, and (6) An integrated program of Quality Assurance. To assure consistency, completeness and the quality of the data produced, a methodology and procedures handbook is being developed. This paper discusses the structure, assets and operations of FRMAC monitoring and analysis and the content and preparation of this handbook

Informatics in radiology: radiology gamuts ontology: differential diagnosis for the Semantic Web.

Budovec, Joseph J; Lam, Cesar A; Kahn, Charles E

2014-01-01

The Semantic Web is an effort to add semantics, or "meaning," to empower automated searching and processing of Web-based information. The overarching goal of the Semantic Web is to enable users to more easily find, share, and combine information. Critical to this vision are knowledge models called ontologies, which define a set of concepts and formalize the relations between them. Ontologies have been developed to manage and exploit the large and rapidly growing volume of information in biomedical domains. In diagnostic radiology, lists of differential diagnoses of imaging observations, called gamuts, provide an important source of knowledge. The Radiology Gamuts Ontology (RGO) is a formal knowledge model of differential diagnoses in radiology that includes 1674 differential diagnoses, 19,017 terms, and 52,976 links between terms. Its knowledge is used to provide an interactive, freely available online reference of radiology gamuts ( www.gamuts.net ). A Web service allows its content to be discovered and consumed by other information systems. The RGO integrates radiologic knowledge with other biomedical ontologies as part of the Semantic Web. © RSNA, 2014.
