The ABR Core Examination stresses integrating physics into real-world clinical practice and, accordingly, has shifted its focus from passive recall of facts to active application of physics principles. Physics education of radiology residents poses a challenge. The traditional method of didactic lectures alone is insufficient, yet it is difficult to incorporate physics teaching consistently into clinical rotations due to time constraints. Faced with this challenge, diagnostic medical physicists who teach radiology residents, have been thinking about how to adapt their teaching to the new paradigm, what to teach and meet expectation of the radiology resident and the radiology residency program. The proposed lecture attempts to discuss above questions. Newly developed diagnostic radiology residents physics curriculum by the AAPM Imaging Physics Curricula Subcommittee will be reviewed. Initial experience on hands-on physics teaching will be discussed. Radiology resident who will have taken the BAR Core Examination will share the expectation of physics teaching from a resident perspective. The lecture will help develop robust educational approaches to prepare radiology residents for safer and more effective lifelong practice.

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

Background In an integrated method of education, medical students are introduced to radiology in their preclinical years. However, no study has been conducted in Pakistan to demonstrate an academic framework of medical radiology education at an undergraduate level. Therefore, we aimed to document and compare the current level of teaching duties, teaching methodologies, and teaching rewards among radiologists and residents in private and public teaching hospitals in Karachi, Pakistan. Methods A survey was conducted among 121 radiologists and residents in two private and two public teaching hospitals in Karachi, Pakistan. Radiologists who were nationally registered with the Pakistan Medical and Dental Council either part-time or full-time were included. Radiology residents and fellows who were nationally registered with the Pakistan Medical and Dental Council were also included. Self-administered questionnaires addressing teaching duties, methods, and rewards were collected from 95 participants. Results The overall response rate was 78.51% (95/121). All of the radiologists were involved in teaching residents and medical students, but only 36% reported formal training in teaching skills. Although most of the respondents (76%) agreed that medical students appeared enthusiastic about learning radiology, the time spent on teaching medical students was less than five hours per week annually (82%). Only 37% of the respondents preferred dedicated clerkships over distributed clerkships (41%). The most common preferred teaching methodology overall was one-on-one interaction. Tutorials, teaching rounds, and problem-based learning sessions were less favored by radiologists than by residents. Teaching via radiology films (86%) was the most frequent mode of instruction. Salary (59%) was the most commonly cited teaching reward. The majority of respondents (88%) were not satisfied with their current level of teaching rewards. Conclusion All radiologists and residents working in an

A computerized index can be used to retrieve cases from a teaching file that have radiographic findings similar to an unknown case. The probability that a user will review cases with a correct diagnosis was estimated with use of radiographic findings of arthritis in hand radiographs of 110 cases from a teaching file. The nearest-neighbor classification algorithm was used as a computer index to 110 cases of arthritis. Each case was treated as an unknown and inputted to the computer index. The accuracy of the computer index in retrieving cases with the same diagnosis (including rheumatoid arthritis, gout, psoriatic arthritis, inflammatory osteoarthritis, and pyrophosphate arthropathy) was measured. A Bayes classifier algorithm was also tested on the same database. Results are presented. The nearest-neighbor algorithm was 83%. By comparison, the estimated accuracy of the Bayes classifier algorithm was 78%. Conclusions: A computerized index to a teaching file based on the nearest-neighbor algorithm should allow the user to review cases with the correct diagnosis of an unknown case, by entering the findings of the unknown case

Radiology seminars using teaching kits

Munro, T.G.

1989-01-01

Clinco-radiological seminars are an effective method of teaching medical students. However, in busy departments it is often difficult to provide enough radiologists for small group instruction. This can be facilitated by the use of prepared teaching kits. Each kit contains a set of duplicated films and a syllabus which gives a short clinical history for each patient and a series of questions to be used to direct the discussion. Each diagnostic problem is chosen to demonstrate core material. We have been using these teaching kits for organ system teaching in the preclerkship year. Teaching kits offer several advantages. They make it easier to recruit seminar leaders through efficient use of their time. The use of duplicated films and a syllabus ensures that all students cover the same material. The syllabus can be used to generate examination questions for reinforcement of important concepts. The kits are also available to students to review alone and can be readily updated as required

Our hospital started the charged particle therapy since 1996. New institutions for charged particle therapy are planned in the world. Our hospital are accepting many visitors from those newly planned medical institutions and having many opportunities to provide with the training to them. Based upon our experiences, we have developed the radiation oncology teaching files system for charged particle therapy. We adopted the PowerPoint of Microsoft as a basic framework of our teaching files system. By using our export function of the viewer any physician can create teaching files easily and effectively. Now our teaching file system has 33 cases for clinical and physics contents. We expect that we can improve the safety and accuracy of charged particle therapy by using our teaching files system substantially.

Software methods that enable navigation of radiology cases on various digital platforms differ between handheld devices and desktop computers. This has resulted in poor compatibility of online radiology teaching files across mobile smartphones, tablets, and desktop computers. A standardized, platform-independent, or "agnostic" approach for presenting online radiology content was produced in this work by leveraging modern hypertext markup language (HTML) and JavaScript web software technology. We describe the design and evaluation of this software, demonstrate its use across multiple viewing platforms, and make it publicly available as a model for future development efforts.

Goske, Marilyn J.; Reid, Janet R.; Yaldoo-Poltorak, Dunya; Hewson, Mariana

2005-01-01

The Accreditation Council for Graduate Medical Education mandates that radiology residency programs teach communication skills to residents. The purpose of this paper is to present a mnemonic, RADPED, that can be used to enhance communication in the radiology setting. It reminds the resident of the salient points to address during an imaging encounter with pediatric patients and their families for the purpose of enhancing communication. Recent history and research in medical communication are reviewed. Various communication guides used by primary care physicians, such as SEGUE, and the Kalamazoo consensus statement are discussed. This methodology was adapted into a format that could be used to teach communication skills to radiology residents in the context of an imaging encounter. RADPED reminds the resident to establish rapportwith the patient, ask questionsas to why the patient and family are presenting for the study, discuss the exam, perform the procedure, use exam distractions, and discussthe results with the referring physician and family when appropriate. This guide is available with movie clips as part of an on-line pediatric radiology curriculum. This simple memory aid promotes the key points necessary to optimize the radiology resident's encounter with pediatric patients and their families. (orig.)

Adobe acrobat: an alternative electronic teaching file construction methodology independent of HTML restrictions.

Katzman, G L

2001-03-01

The goal of the project was to create a method by which an in-house digital teaching file could be constructed that was simple, inexpensive, independent of hypertext markup language (HTML) restrictions, and appears identical on multiple platforms. To accomplish this, Microsoft PowerPoint and Adobe Acrobat were used in succession to assemble digital teaching files in the Acrobat portable document file format. They were then verified to appear identically on computers running Windows, Macintosh Operating Systems (OS), and the Silicon Graphics Unix-based OS as either a free-standing file using Acrobat Reader software or from within a browser window using the Acrobat browser plug-in. This latter display method yields a file viewed through a browser window, yet remains independent of underlying HTML restrictions, which may confer an advantage over simple HTML teaching file construction. Thus, a hybrid of HTML-distributed Adobe Acrobat generated WWW documents may be a viable alternative for digital teaching file construction and distribution.

2004-01-01

This article briefly describes our original radiological reporting system. This system was developed with the widely used database software FileMakerPro (ver 5.5). The reporting system can obtain information about patients and examinations from a radiology information system (RIS) by the Open DataBase Connectivity (ODBC) technique. By clicking the button on the reporting system, the corresponding Digital Imaging and Communications in Medicine (DICOM) images can be displayed on a picture archiving and communication system (PACS) workstation monitor. Reference images in JPEG format can be easily moved from PACS to the reporting system. Reports produced by the reporting system are distributed to the hospital information system (HIS) in Portable Document Format (PDF), through another web server. By utilizing the capacity of FileMakerPro, the human-machine interface of the system has been able to be improved easily. In addition, cooperation with HIS, RIS, and PACS could be constructed. Therefore, this original system would contribute to increasing the efficiency of radiological diagnosis. (author)

Integrating Radiology and Anatomy Teaching in Medical Education in the UK--The Evidence, Current Trends, and Future Scope.

Science.gov (United States)

Heptonstall, N B; Ali, T; Mankad, K

2016-04-01

This review article presents the current evidence of the importance of integrating radiology and anatomy in medical education in the UK, a recommendation by a number of key anatomy, education, and radiology organizations. Current evidence highlights that on average only 5% of total teaching time in medical education is dedicated to radiology. Often, radiology teaching does not adequately fulfill students' learning needs and potentially leaves them underprepared for medical practice. Benefits of integrating radiology and anatomy include improved clinical application of anatomy, an increase in student's interest in anatomy, and ultimately improved radiological interpretation. Various modalities exist for the integration of radiology and anatomy, facilitated by the vast portability of radiological images. It appears that combining radiological resources with traditional anatomy teaching methodology in a blended approach is most beneficial. Copyright © 2016 The Association of University Radiologists.

Rengier, Fabian; Tengg-Kobligk, Hendrik von; Doll, Sara; Kirsch, Joachim; Kauczor, Hans-Ulrich; Giesel, Frederik L.

2009-01-01

This article presents a new way of teaching by integrating both anatomy and radiology using three-dimensional image post-processing tools. One preclinical and one clinical module were developed for integrated teaching of anatomy and radiology. Potential benefits were assessed by anonymous evaluation among the 176 participating students. The students highly appreciated the new approach, especially the high degree of interactivity with the post-processing software and the possibility to correlate the real dissection with the virtual dissection. Students agreed that three-dimensional imaging and post-processing improved their understanding of difficult anatomical topics and topographical relations. We consider the new approach to provide great additional benefits for participating students regarding preparation for everyday clinical practice. In particular, it imparts familiarity with imaging and image post-processing techniques and may improve anatomical understanding, radiological diagnostic skills and three-dimensional appreciation.

Balkman, Jason D; Loehfelm, Thomas W

2014-01-01

Recent improvements in Web and mobile technology, along with the widespread use of handheld devices in radiology education, provide unique opportunities for creating scalable, universally accessible, portable image-rich radiology case files. A cloud database and a Web-based application for radiologic images were developed to create a mobile case file with reasonable usability, download performance, and image quality for teaching purposes. A total of 75 radiology cases related to breast, thoracic, gastrointestinal, musculoskeletal, and neuroimaging subspecialties were included in the database. Breast imaging cases are the focus of this article, as they best demonstrate handheld display capabilities across a wide variety of modalities. This case subset also illustrates methods for adapting radiologic content to cloud platforms and mobile devices. Readers will gain practical knowledge about storage and retrieval of cloud-based imaging data, an awareness of techniques used to adapt scrollable and high-resolution imaging content for the Web, and an appreciation for optimizing images for handheld devices. The evaluation of this software demonstrates the feasibility of adapting images from most imaging modalities to mobile devices, even in cases of full-field digital mammograms, where high resolution is required to represent subtle pathologic features. The cloud platform allows cases to be added and modified in real time by using only a standard Web browser with no application-specific software. Challenges remain in developing efficient ways to generate, modify, and upload radiologic and supplementary teaching content to this cloud-based platform. Online supplemental material is available for this article. ©RSNA, 2014.

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.

2015-04-01

This study describes the state of preclinical radiology curricula in North American allopathic, osteopathic, and podiatric medical schools. An online survey of teaching methods, radiology topics, and future plans was developed. The Associations of American Medical Colleges, Colleges of Osteopathic Medicine, and Colleges of Podiatric Medicine listing for all US, Canadian, and Puerto Rican schools was used for contact information for directors of anatomy and/or radiology courses. Letters were sent via e-mail to 198 schools, with a link to the anonymous survey. Of 198 schools, 98 completed the survey (48%). Radiology curricula were integrated with other topics (91%), and taught by anatomists (42%) and radiologists (43%). The majority of time was spent on the topic of anatomy correlation (35%). Time spent teaching general radiology topics in the curriculum, such as physics (3%), modality differences (6%), radiation safety (2%), and contrast use (2%) was limited. Most schools had plans to implement an innovative teaching method in the near future (62%). The major challenges included limits on: time in the curriculum (73%); resources (32%); and radiology faculty participation (30%). A total of 82% reported that their curriculum did not model the suggestions made by the Alliance of Medical Student Educators in Radiology. This survey describes the current state of preclinical radiology teaching: curricula were nonstandard, integrated into other courses, and predominantly used for anatomy correlation. Other important contextual principles of the practice of radiology were seldom taught. Copyright © 2015 American College of Radiology. Published by Elsevier Inc. All rights reserved.

Purpose  New teaching formats are required to implement competency-based teaching in radiology teaching. Therefore, we have established and evaluated two practical competency-based radiological courses. Materials and Methods  The courses were held in a multimedia room with 25 computers and a professional DICOM viewer. Students were taught basic image analysis and presented clinical cases with a DICOM viewer under supervision of an instructor using desktop monitoring software. Two courses (elective course and obligatory course) were evaluated by the students (n = 160 and n = 100) and instructors (n = 9) using an anonymized online survey. Results  Courses were evaluated positively by the students and instructors. From the perspective of the students, the courses increased understanding of cross-sectional anatomy (elective/obligatory course: 97 %/95 %) and radiologic findings (97 %/99 %). Furthermore, the course increased the students' interest in radiology (61 %/65 %). The students considered this way of teaching to be relevant to their future occupation (92 % of students in the obligatory course). The higher incidence of teacher-student interaction and the possibility of independent image analysis were rated positively. The majority of instructors did not observe increased distractibility due to the computers (67 %) or notice worse preparation for MC tests (56 %). However, 56 % of instructors reported greater preparation effort. Conclusion  Practical competency-based radiological teaching using a DICOM viewer is a feasible innovative approach with high acceptance among students and instructors. It fosters competency-based learning as proposed by the model curriculum of the German Radiological Society (DRG) and the National Competency-based Catalogue of Learning Objectives for Undergraduate Medical Education (NKLM). Key Points   · Practical competency-based radiological teaching is highly accepted by students and instructors

2017-01-01

One of the main causes of radiological accidents is the lack of knowledge in radiological protection of workers. In order to meet the needs of professionals in radiology techniques in training in industrial radiology and radiological protection, the Training Course in Industrial Radiology was created in 2009 by MAXIM, in partnership with the Casa Branca Faculty. The objective is to present the structure and methodology of teaching used in this course to reach the objectives of training professionals with solid knowledge in industrial radiology, as well as to mention the challenges of this training. For the elaboration of the study, a statistical data base and theoretical analysis of the teaching structure of the course was used. Professional training in industrial radiology is subdivided into basic, specific, practical and complementary modules, totaling a workload of 360 hours. It is noted that most of the professionals trained come from the great urban centers of the country, favoring employability in the port terminals and industries that are located in these regions. It is concluded, therefore, that it is necessary and of great importance for the growing industrial market, the formation of new professionals, mainly in cities of the interior

Aim: To review the initial experience of blending a variety of online educational techniques with traditional face to face or contact-based teaching methods to deliver final year undergraduate radiology content at a UK Medical School. Materials and methods: The Brighton and Sussex Medical School opened in 2003 and offers a 5-year undergraduate programme, with the final 5 spent in several regional centres. Year 5 involves several core clinical specialities with onsite radiology teaching provided at regional centres in the form of small-group tutorials, imaging seminars and also a one-day course. An online educational module was introduced in 2007 to facilitate equitable delivery of the year 5 curriculum between the regional centres and to support students on placement. This module had a strong radiological emphasis, with a combination of imaging integrated into clinical cases to reflect everyday practice and also dedicated radiology cases. For the second cohort of year 5 students in 2008 two additional online media-rich initiatives were introduced, to complement the online module, comprising imaging tutorials and an online case discussion room. Results: In the first year for the 2007/2008 cohort, 490 cases were written, edited and delivered via the Medical School managed learning environment as part of the online module. 253 cases contained a form of image media, of which 195 cases had a radiological component with a total of 325 radiology images. Important aspects of radiology practice (e.g. consent, patient safety, contrast toxicity, ionising radiation) were also covered. There were 274,000 student hits on cases the first year, with students completing a mean of 169 cases each. High levels of student satisfaction were recorded in relation to the online module and also additional online radiology teaching initiatives. Conclusion: Online educational techniques can be effectively blended with other forms of teaching to allow successful undergraduate delivery of

Effective communication is essential for high quality care, yet little is known about radiologists' communication with patients, what constitutes "best communication practices," and how best to teach and evaluate it. We piloted educational strategies and an assessment instrument to teach and evaluate radiologists' communication skills. We focused on communication in the diagnostic mammography suite, where patient-radiologist interactions are often intense and stressful. We adapted existing instruments to create a Radiology Communication Skills Assessment Tool (RCSAT). We piloted an educational program that included patients as teachers and raters of interpersonal and communication skills, and implemented a radiology objective structured clinical examination (OSCE). We measured radiology residents' self-assessed skills, confidence and stress, as well as patient-rated communication skills using the RCSAT. Residents' baseline self-assessed communication skills regarding abnormal mammograms were fair, confidence in their communication was minimal, and they found this communication stressful. Overall baseline communication skills, rated by patient-teachers using the RCSAT, were 3.62 on a 5-point scale (1 = poor to 5 = excellent). Analysis of post-OSCE debriefing comments yielded nine themes regarding effective radiology communication, as well as residents' reflections on the communication challenges they experience. The themes were integrated into subsequent RCSAT revisions. Residents' reflections were used to inform teaching workshops. Educational curricula on communication about difficult information can be implemented in radiology training programs. Radiology residents' performance can be assessed using a communication skills assessment tool during standardized patient-teacher encounters. Further research is necessary in this important domain.

Teaching and Assessing Professionalism in Radiology: Resources and Scholarly Opportunities to Contribute to Required Expectations.

Science.gov (United States)

Kelly, Aine Marie; Mullan, Patricia B

2018-05-01

Teaching and assessing trainees' professionalism now represents an explicit expectation for Accreditation Council Graduate Medical Education-accredited radiology programs. Challenges to meeting this expectation include variability in defining the construct of professionalism; limits of traditional teaching and assessment methods, used for competencies historically more prominent in medical education, for professionalism; and emerging expectations for credible and feasible professionalism teaching and assessment practices in the current context of health-care training and practice. This article identifies promising teaching resources and methods that can be used strategically to augment traditional teaching of the cognitive basis for professionalism, including role modeling, case-based scenarios, debriefing, simulations, narrative medicine (storytelling), guided discussions, peer-assisted learning, and reflective practice. This article also summarizes assessment practices intended to promote learning, as well as to inform how and when to assess trainees as their professional identities develop over time, settings, and autonomous practice, particularly in terms of measurable behaviors. This includes assessment tools (including mini observations, critical incident reports, and appreciative inquiry) for authentic assessment in the workplace; engaging multiple sources (self-, peer, other health professionals, and patients) in assessment; and intentional practices for trainees to take responsibility for seeking our actionable feedback and reflection. This article examines the emerging evidence of the feasibility and value added of assessment of medical competency milestones, including professionalism, coordinated by the Accreditation Council Graduate Medical Education in radiology and other medical specialties. Radiology has a strategic opportunity to contribute to scholarship and inform policies in professionalism teaching and assessment practices. Copyright © 2018 The

Automation of Educational Tasks for Academic Radiology.

The process of education involves a variety of repetitious tasks. We believe that appropriate computer tools can automate many of these chores, and allow both educators and their students to devote a lot more of their time to actual teaching and learning. This paper details tools that we have used to automate a broad range of academic radiology-specific tasks on Mac OS X, iOS, and Windows platforms. Some of the tools we describe here require little expertise or time to use; others require some basic knowledge of computer programming. We used TextExpander (Mac, iOS) and AutoHotKey (Win) for automated generation of text files, such as resident performance reviews and radiology interpretations. Custom statistical calculations were performed using TextExpander and the Python programming language. A workflow for automated note-taking was developed using Evernote (Mac, iOS, Win) and Hazel (Mac). Automated resident procedure logging was accomplished using Editorial (iOS) and Python. We created three variants of a teaching session logger using Drafts (iOS) and Pythonista (iOS). Editorial and Drafts were used to create flashcards for knowledge review. We developed a mobile reference management system for iOS using Editorial. We used the Workflow app (iOS) to automatically generate a text message reminder for daily conferences. Finally, we developed two separate automated workflows-one with Evernote (Mac, iOS, Win) and one with Python (Mac, Win)-that generate simple automated teaching file collections. We have beta-tested these workflows, techniques, and scripts on several of our fellow radiologists. All of them expressed enthusiasm for these tools and were able to use one or more of them to automate their own educational activities. Appropriate computer tools can automate many educational tasks, and thereby allow both educators and their students to devote a lot more of their time to actual teaching and learning.

PathBot: A Radiology-Pathology Correlation Dashboard.

Science.gov (United States)

Kelahan, Linda C; Kalaria, Amit D; Filice, Ross W

2017-12-01

Pathology is considered the "gold standard" of diagnostic medicine. The importance of radiology-pathology correlation is seen in interdepartmental patient conferences such as "tumor boards" and by the tradition of radiology resident immersion in a radiologic-pathology course at the American Institute of Radiologic Pathology. In practice, consistent pathology follow-up can be difficult due to time constraints and cumbersome electronic medical records. We present a radiology-pathology correlation dashboard that presents radiologists with pathology reports matched to their dictations, for both diagnostic imaging and image-guided procedures. In creating our dashboard, we utilized the RadLex ontology and National Center for Biomedical Ontology (NCBO) Annotator to identify anatomic concepts in pathology reports that could subsequently be mapped to relevant radiology reports, providing an automated method to match related radiology and pathology reports. Radiology-pathology matches are presented to the radiologist on a web-based dashboard. We found that our algorithm was highly specific in detecting matches. Our sensitivity was slightly lower than expected and could be attributed to missing anatomy concepts in the RadLex ontology, as well as limitations in our parent term hierarchical mapping and synonym recognition algorithms. By automating radiology-pathology correlation and presenting matches in a user-friendly dashboard format, we hope to encourage pathology follow-up in clinical radiology practice for purposes of self-education and to augment peer review. We also hope to provide a tool to facilitate the production of quality teaching files, lectures, and publications. Diagnostic images have a richer educational value when they are backed up by the gold standard of pathology.

All the 33 male doctors and para-medical staff employed in the radiology departments of two teaching hospitals have been studied for their fertility status. Their mean age was 32.5 years and they had been doing radiological work for 8.6 years on an average. Out of the 33 males, all of whom were married, one had primary infertility with severe oligospermia. He was successfully treated with oral vitamin A and E along with a 3-month off from handling x-ray machines; the child born was healthy and normal. Another 5 subjects had been married for only less than two years and their seminograms were essentially normal. They were classified as 'Unproven fertility'. The remaining 27 persons had fathered 61 children-16 born before the father had started working in radiology and 45 conceived later. There was 1 case of still-birth and 1 of microcephaly. However, the overall incidence of infertility and congenital defects was not significantly different than in the general population. (author)

A New Approach to Learning How to Teach: medical students as instructional designers

Paul F. Wimmers

2011-07-01

Full Text Available As students at the David Geffen School of Medicine at UCLA, the student authors were given the opportunity to develop their own creative projects which would be used to teach future medical students. They chose their own topics, planned and researched their projects, and then implemented the projects in interactive digital Adobe Flash files. In the first project they created interactive case-based radiology teaching files. In the second project they integrated photographic images into the existing illustrative anatomy files. Students in subsequent years have learned from these files on computers both at home and in the school's anatomy lab. The experience of creating the files served as an opportunity for hands-on learning for the student authors, both of the material and of the practice of teaching. In this paper they describe why they undertook these projects, what exactly they did, and the impact their creation had on them. The projects demonstrate that student-driven educational materials are both possible and beneficial. Furthermore, their experience has allowed them to conclude that faculty at other medical schools should consider providing students with opportunities to develop their own creative projects that contribute to the curriculum.

Because of the rapid increase in clinical workload in academic radiology departments, time for teaching rotating residents is getting more and more limited. As a solution to this problem, we introduced the Intranet Journal of Chest Radiology as a comprehensive innovative tool for assisting resident education. The Intranet Journal of Chest Radiology is constructed using Microsoft FrontPage version 2002 (Microsoft Corp, Redmond, WA) and is hosted in our departmental web server (Beth Israel Deaconess Medical Center, Boston, MA). The home page of the intranet journal provides access to the main features, "Cases of the Month," "Teaching File," "Selected Articles for Residents," "Lecture Series," and "Current Publications." These features provide quick access to the selected radiology articles, the interesting chest cases, and the lecture series and current publication from the chest section. Our intranet journal has been well utilized for 6 months after its introduction. It enhances residents' interest and motivation to work on case collections, to search and read articles, and to generate interest in research. Frequent updating is necessary for the journal to be kept current, relevant, and well-utilized. The intranet journal serves as a comprehensive innovative solution for resident education, providing basic educational resources and opportunities of interactive participation by residents.

Adams, W.M.

1998-01-01

Radiologists from 28 veterinary schools and one private teaching hospital responded to a survey questionnaire focused on diagnostic image reporting. Radiologists at 26 hospitals generated a hard copy report on essentially all imaging studies performed. At 25 hospitals, radiologists dictated and transcriptionists typed all or most reports; radiologists at two institutions typed all or some of their reports. At five hospitals, preliminary and/or final handwritten reports were generated. The range of reports generated per day was <10 to 40 per radiologist on duty. Seven respondents generated reports as films came from the processor and another 12 routinely generated reports the day the studies were completed. Clinician access to a processed report averaged 2 to 4 days after study was completed (reported range: several hours to 7 or more days). Fifteen responding radiologists personally mounted films from storage jackets for a majority of their reporting. Fourteen respondents generated reports from films mounted on motorized or stationary viewers. Nineteen respondents generated reports in a busy viewing area where they were frequently interrupted. Radiologists' impression of clinician and resident satisfaction regarding availability of radiology reports was that they were satisfied or very satisfied at 15 of the 29 hospitals. Five respondents reported that clinicians and residents were not concerned about availability of processed radiology reports. Thirteen radiologists were planning to change their reporting method within the next 2 years. The change most frequently sought (12 respondents) was to decrease turn-around time of reports. Ten radiologists indicated an interest in trying a voice recognition dictation system. The most common reasons given for not planning any changes in radiology reporting in the next 2 years were: limited number of radiologists (8) and 1 ''satisfied as is'' (7). Turn-around of radiology reports at these veterinary institutions averaged 2

The aim of this study was to describe the implementation of one form of social media (Twitter) in an oral radiology course and evaluate dental students' use and perceptions of this technology for teaching and learning. An author-developed questionnaire was used to solicit second-year students' knowledge, use, and perceptions of Twitter for teaching and learning in an oral radiology course at one U.S. dental school. A combination of Likert scales, multiple allowable answers, and an open-ended comment question was employed. The questionnaire was piloted in spring 2010 followed by data collection in spring 2011. Out of 45 students, 40 (88.9%) completed the questionnaire. Of the respondents, 95% reported having not used Twitter prior to their second year of dental school; 55% of them created an account for the course. The top two reasons they gave for creating an account were viewing radiographic examples and staying informed about questions and answers that were posted. The top two reasons they gave for not creating an account were that the content was viewable online without an account and not wanting another online account. The students perceived the Twitter sessions as helpful and reported it improved accessibility to the instructor. The results of this study challenged the assumption that dental students are well versed in all forms of social media, but overall, these students agreed that the use of Twitter had enhanced the learning environment in the radiology course.

The ABR Core Examination stresses integrating physics into real-world clinical practice and, accordingly, has shifted its focus from passive recall of facts to active application of physics principles. Physics education of radiology residents poses a challenge. The traditional method of didactic lectures alone is insufficient, yet it is difficult to incorporate physics teaching consistently into clinical rotations due to time constraints. Faced with this challenge, diagnostic medical physicists who teach radiology residents, have been thinking about how to adapt their teaching to the new paradigm, what to teach and meet expectation of the radiology resident and the radiology residency program. The proposed lecture attempts to discuss above questions. Newly developed diagnostic radiology residents physics curriculum by the AAPM Imaging Physics Curricula Subcommittee will be reviewed. Initial experience on hands-on physics teaching will be discussed. Radiology resident who will have taken the BAR Core Examination will share the expectation of physics teaching from a resident perspective. The lecture will help develop robust educational approaches to prepare radiology residents for safer and more effective lifelong practice. Learning Objectives: Learn updated physics requirements for radiology residents Pursue effective approaches to teach physics to radiology residents Learn expectation of physics teaching from resident perspective J.

 Based on evaluation and examination results of students, a necessity for improvement of so far purely instructor-based radiological teaching at the local institution was determined. Aim of our study was to use one out of eight seminars to exemplify adaptation of the teaching concept according to learning theory knowledge, to determine the resulting effects and to interpret them.  The institutional review board approved the prospective study of the seminar conversion, which was performed after the end of the winter semester 2015/2016. Didactically, this included a course split into online preparation, attendance phase and online follow-up with integration of interactive scaffolding, practice-oriented clinical teaching according to Stanford, Peyton skills transfer and extensive feedback into the attendance phase. At the beginning and at the end of each course, each student filled in identical, standardized questionnaires (n = 256 before and after conversion) using a 5-point Likert scale (1: very good; to 5: deficient) and additionally answered two randomly chosen written examination questions from a content-adapted questionnaire pool of the last five years. For statistical evaluation, the Mann-Whitney U-Test was used for evaluation data and Fisher's Exact test for exam questions.  Before/after conversion, the subjective total evaluation score of students was 3.22 (mean value) ± 1.51 (standard deviation) / 1.66 ± 0.78 (p theory concepts with reasonable effort.. · In a test seminar this improved the evaluation results of the teaching unit by the students.. · In addition, this also led to a higher rate of correctly answered examination questions from past state examinations.. · This supports further steps towards excellent radiological teaching.. · Wirth S, William Y, Paolini M et al.

Radiology education: a radiology curriculum for all medical students?

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

2017-09-26

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

Objectives: The purpose of the present study is to describe how undergraduate radiology teaching is organized in Europe and to identify important characteristics of undergraduate radiology curriculum. Methods: An electronic survey on undergraduate teaching was distributed by the European Society of Radiology (ESR) to 38 national delegates of the ESR Education Committee. Results: The 'classic type' of radiology teaching method is more frequent than the 'modular type'. In 38% of medical training centres the first experience with radiology is in pre-clinical years. The students enrolled in the fourth medical year experience the largest involvement in radiology education. The total number of teaching hours (mean 89 h, median 76 h) varies across the countries and differs depending on the radiological topic (mean across all topics 14.8 h, median 13). Written tests and oral exams were the most frequently used examination modes. Clerkships are reported as a key part of training. Conclusion: This first international comparative study of undergraduate radiological curriculum in Europe identifies a large number of differences in curriculum content and teaching methods throughout Europe. More research is needed to establish the radiological educational competences resulting from these differing curricula's to improve and to standardize the teaching according to (inter)national and institutional needs.

Full Text Available Introduction. Cadaveric dissections and prosections have traditionally been part of undergraduate medical teaching. Materials and Methods. Hundred and fifty-nine first-year students in the Faculty of Medicine, University of Colombo, were invited to participate in the above study. Students were randomly allocated to two age and gender matched groups. Both groups were exposed to identical series of lectures regarding anatomy of the abdomen and conventional cadaveric prosections of the abdomen. The test group (n=77, 48.4% was also exposed to cadaveric cross-sectional slices of the abdomen to which the control group (n=82, 51.6% was blinded. At the end of the teaching session both groups were assessed by using their performance in a timed multiple choice question paper as well as ability to identify structures in abdominal CT films. Results. Scores for spatial and radiological anatomy were significantly higher among the test group when compared with the control group (P<0.05, CI 95%. Majority of the students in both control and test groups agreed that cadaveric cross section may be useful for them to understand spatial and radiological anatomy. Conclusion. Introduction of cadaveric cross-sectional prosections may help students to understand spatial and radiological anatomy better.

Uroradiology is an up-to-date, image-oriented reference in the style of a teaching file that has been designed specifically to be of value in clinical practice. All aspects of the imaging of urologic diseases are covered, and case studies illustrate the findings obtained with the relevant imaging modalities in both common and uncommon conditions. Most chapters focus on a particular clinical problem, but normal findings, congenital anomalies, and interventions are also discussed and illustrated. In this second edition, the range and quality of the illustrations have been enhanced, and many schematic drawings have been added to help readers memorize characteristic imaging findings through pattern recognition. The accompanying text is concise and informative. Besides serving as an outstanding aid to differential diagnosis, this book will provide a user-friendly review tool for certification or recertification in radiology. (orig.)

Radioecology teaching: response to a nuclear or radiological emergency

2006-03-01

The study of environmental radioactivity is a topic not usually included in physics courses in Brazilian and Latin American universities. Consequently, high-school teachers rarely have the opportunity to discuss with their students the effects of radioactive contamination in forest and agricultural ecosystems following a nuclear or radiological emergency, or to conduct experiments to illustrate the methodology employed to assess the consequences of such an event. This paper presents a laboratory experiment which could be included as part of a teaching programme on ionizing radiation physics, addressing some of the aspects related to the fate and effects of anthropogenic radionuclides following a radiation emergency, and the possible physical countermeasures that could be adopted in order to reduce their impact on the environment.

Purpose: Having access to a library of radiological images in the university setting is important for teaching and learning in diagnostic radiography. Modern modalities such as PETCT create data volumes rather than single static 2D images. A PACS repository of images alone does not constitute a teaching library without some text based searchable index. A review of several options for acquiring a digital teaching library (DTL) of such indexed DICOM data is presented. Discussion: The data protection principles, current guidance and potential methods for migrating and cleansing large quantities of DICOM data from a clinical PACS prior to transfer to a university setting is discussed. The chosen method is described and the important enabling technology identified. Various methods of index construction are outlined and a method of migrating and cleansing HL7 data from a clinical RIS described. Results: Three terabytes of de-normalised DICOM image files were cleansed of patient, staff and geographic identifiers, within the header tags and pixel data. These files were then migrated to an educational PACS hosted at a university. A searchable index database was created based on 90,200 reports and associated data, and 886,263 DICOM headers to enable meaningful results to be found from the 51,304 unique patient specific cases. Conclusion: A large DTL in the university setting using PACS technology is becoming a valuable resource for teaching, learning and assessment.

The Socratic method has long been a traditional teaching method in medicine and law. It is currently accepted as the standard of teaching in clinical wards, while the didactic teaching method is widely used during the first 2 years of medical school. There are arguments in support of both styles of teaching. After attending a radiology conference demonstrating different teaching methods, third-year and fourth-year medical students were invited to participate in an online anonymous survey. Of the 74 students who responded, 72% preferred to learn radiology in an active context. They preferred being given adequate time to find abnormalities on images, with feedback afterward from instructors, and they thought the best approach was a volunteer-based system of answering questions using the Socratic method in the small group. They desired to be asked questions in a way that was constructive and not belittling, to realize their knowledge deficits and to have daily pressure to come prepared. The respondents thought that pimping was an effective teaching tool, supporting previous studies. When teaching radiology, instructors should use the Socratic method to a greater extent. Combining Socratic teaching with gentle questioning by an instructor through the use of PowerPoint is a preferred method among medical students. This information is useful to improve medical education in the future, especially in radiology education. Copyright © 2011 AUR. Published by Elsevier Inc. All rights reserved.

2012-01-01

Aim: To establish an expert consensus of what, when, and how the teaching of radiology should be incorporated into the core undergraduate medical curriculum. Methods and materials: This Delphi survey consisted of four iterative rounds, with feedback given at the start of each successive round in the form of the results of the previous round. The participants consisted of both radiologists and non-radiologists with significant interest and involvement in radiology and undergraduate/Foundation training. The study addressed the questions of how, where, when, and by whom radiology should be taught. Results: The number of responses in rounds 1–4 was 20, 23, 41, and 25 (25, 22, 31, and 61% response rate, respectively). There was good consensus amongst the responders on the following: radiology teaching must be delivered in conjunction with anatomy and clinical case-based teaching, if possible in the department of radiology on picture archiving and communication system (PACS) workstations, and the teaching should be delivered by a competent and credentialled individual. Case-based assessment was the most agreed method of assessment. The majority of the responders concurred that the curriculum should include general indications for commonly requested radiological investigations, consent and safety issues around radiological tests, and their basic interpretation. Conclusion: The consensus points reached by the present study not only serve as directive principles for developing a more comprehensive radiology curriculum, but also places emphasis on a broader range of knowledge required to promote the best use of a department of radiology by junior doctors in an attempt to improve patient experiences and care.

There are little data as to whether appropriate, cost effective, and safe ordering of imaging examinations are adequately taught in US medical school curricula. We sought to determine the proportion of noninterpretive content (such as appropriate ordering) versus interpretive content (such as reading a chest x-ray) in the top-selling medical student radiology textbooks. We performed an online search to identify a ranked list of the six top-selling general radiology textbooks for medical students. Each textbook was reviewed including content in the text, tables, images, figures, appendices, practice questions, question explanations, and glossaries. Individual pages of text and individual images were semiquantitatively scored on a six-level scale as to the percentage of material that was interpretive versus noninterpretive. The predominant imaging modality addressed in each was also recorded. Descriptive statistical analysis was performed. All six books had more interpretive content. On average, 1.4 pages of text focused on interpretation for every one page focused on noninterpretive content. Seventeen images/figures were dedicated to interpretive skills for every one focused on noninterpretive skills. In all books, the largest proportion of text and image content was dedicated to plain films (51.2%), with computed tomography (CT) a distant second (16%). The content on radiographs (3.1:1) and CT (1.6:1) was more interpretive than not. The current six top-selling medical student radiology textbooks contain a preponderance of material teaching image interpretation compared to material teaching noninterpretive skills, such as appropriate imaging examination selection, rational utilization, and patient safety.

2014-06-01

Purpose: To enhance the learning process in the teaching of medical physics by providing a venue to experience the historical equipment and devices of radiology. Methods: We have created a museum by assembling a large collection of equipment and artifacts related to radiology and medical physics. As part of a learning-in-context educational approach, classes for a survey course in medical physics are held in the museum so that students are able to visually and tangibly experience the implements of radiology, while related topics are discussed. The students learn how x-ray equipment and techniques evolved throughout the years and they learn to appreciate the differences and similarities between current x-ray technology and that of the early days. The collection contains items dating from the era of the discovery of x-rays up to recent times and includes gas x-ray tubes, hand-held fluoroscopes, generators, spark-gap kV meters, stereoscopes, glass-plate radiographs, a photofluorographic unit, wood-interspaced grid, flat-panel detector, linear-accelerator klystron, and brachytherapy radium applicators, as well as an extensive library containing some of the seminal literature of the field so that students can delve deeper into the technology. In addition to the classes, guided tours are provided for radiologic-technology, bioengineering, physics and medical students, as well as group and individual tours for the general public. Results: Student course assessments have consistently included positive expressions of their experience in the museum. Numerous students have volunteered to assist with display preparation and have learned by researching the content. Many individuals have been attracted on a walk-in basis and have expressed a deep curiosity in the technology, with positive feedback. Conclusion: The museum and its artifacts have been invaluable in stimulating interest in the history and technology of medical physics. Students and visitors alike obtain a deeper

I wanted to describe a method to create teaching movies with using screen recordings, and I wanted to see if self-learning movies are useful for medical students. Teaching movies were created by direct recording of the screen activity and voice narration during the interpretation of educational cases; we used a PACS system and screen recording software for the recording (CamStudio, Rendersoft, U.S.A.). The usefulness of teaching movies for seft-learning of abdominal CT anatomy was evacuated by the medical students. Creating teaching movie clips with using screen recording software was simple and easy. Survey responses were collected from 43 medical students. The contents of teaching movie was adequately understandable (52%) and useful for learning (47%). Only 23% students agreed the these movies helped motivated them to learn. Teaching movies were more useful than still photographs of the teaching image files. The students wanted teaching movies on the cross-sectional CT anatomy of different body regions (82%) and for understanding the radiological interpretation of various diseases (42%). Creating teaching movie by direct screen recording of a radiologist's interpretation process is easy and simple. The teaching video clips reveal a radiologist's interpretation process or the explanation of teaching cases with his/her own voice narration, and it is an effective self-learning tool for medical students and residents.

Purpose: Our purpose is to evaluate the effectiveness of our two year physics course in preparing radiology residents for the American Board of Radiology (ABR) diagnostic radiology exam. Methods: We designed a new two-year physics course that integrates radiology clinical content and practice and is primarily based on the AAPM curriculum and RSNA/AAPM physics modules. Biweekly classes focus on relevant concepts from assigned reading and use audience response systems to encourage participation. Teaching efficiency is optimized through lecturer rotations of physicists, radiologists, and guest speakers. An emphasis is placed on clinical relevance by requiring lab work and providing equipment demonstrations. Periodic quiz were given during the course. The course website was also redesigned for usability, and physics review lectures were conducted two weeks before the board exam to refresh key concepts. At the completion of our first two-year course, we conducted a confidential evaluation of the faculty and course. The evaluation assessed metrics such as overall organization, clinical relevance of content, and level of difficulty, with a rating scale from poor to excellent. Results: Our evaluation indicated that the redesigned course provided effective board exam preparation, with most responses between good and excellent. There was some criticism on the course length and on chronological discontinuity, but the review lectures were appreciated by the residents. All of our residents passed the physics component of the ABR exam with scores exceeding the minimum passing score by a significant margin. Conclusion: The course evaluation and board exam results indicate that our new two-year course format provides valuable board exam preparation. This is possible thanks to the time and effort taken by the physics faculty on ensuring the residents get quality physics education

To examine the impact that anatomy-focused radiology teaching has on non-examined knowledge regarding radiation safety and radiology as a specialty. First-year undergraduate medical students completed surveys prior to and after undertaking the first-year anatomy programme that incorporates radiological anatomy. Students were asked opinions on preferred learning methodology and tested on understanding of radiology as a specialty and radiation safety. Pre-module and post-module response rates were 93 % (157/168) and 85 % (136/160), respectively. Pre-module and post-module, self-directed learning (SDL) ranked eighth (of 11) for preferred gross-anatomy teaching formats. Correct responses regarding radiologist/radiographer roles varied from 28-94 % on 16 questions with 4/16 significantly improving post-module. Identification of modalities that utilise radiation significantly improved for five of eight modalities post-module but knowledge regarding relative amount of modality-specific radiation use was variable pre-module and post-module. SDL is not favoured as an anatomy teaching method. Exposure of students to a radiological anatomy module delivered by senior clinical radiologists improved basic knowledge regarding ionising radiation use, but there was no improvement in knowledge regarding radiation exposure relative per modality. A possible explanation is that students recall knowledge imparted in didactic lectures but do little reading around the subject when the content is not examined. • Self-directed learning is not favoured as a gross anatomy teaching format amongst medical students. • An imaging anatomy-focused module improved basic knowledge regarding ionising radiation use. • Detailed knowledge of modality-specific radiation exposure remained suboptimal post-module. • Knowledge of roles within a clinical radiology department showed little change post-module.

The purpose of this study was to track the graduates of the Los Angeles College of Chiropractic (LACC) radiology residency program, review their scholarly productivity, and report those involved in teaching and leadership positions. Former LACC residents' career information was identified through publicly available electronic documents including Web sites and social media. PubMed and the Index to Chiropractic Literature databases were searched for chiropractic graduate job surveys, and proportional comparisons were made between the career paths of LACC radiology residency graduates and those of non-residency-trained chiropractors. Of 47 former LACC residents, 28 (60%) have or previously had careers in tertiary (chiropractic) education; and 12 (26%) have attained a department chair position or higher at tertiary teaching institutions. Twenty-two (47%) have or previously had private radiology practices, whereas 11 (23%) have or previously had clinical chiropractic practices. Often, residency graduates hold or have held 2 of these positions at once; and one, all 3. Chapters or books were authored by 13 (28%). Radiology residency LACC graduates are professionally active, particularly in education, and demonstrate scholarly productivity.

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

To determine the benefit of the addition of low-fidelity simulation-based training to the standard didactic-based training in teaching radiology residents common CT-guided procedures. This was a prospective study involving 24 radiology residents across all years in a university program. All residents underwent standard didactic lecture followed by low-fidelity simulation-based training on three common CT-guided procedures: random liver biopsy, lung nodule biopsy, and drain placement. Baseline knowledge, confidence, and performance assessments were obtained after the didactic session and before the simulation training session. Approximately 2 months later, all residents participated in a simulation-based training session covering all three of these procedures. Knowledge, confidence, and performance data were obtained afterward. These assessments covered topics related to preprocedure workup, intraprocedure steps, and postprocedure management. Knowledge data were collected based on a 15-question assessment. Confidence data were obtained based on a 5-point Likert-like scale. Performance data were obtained based on successful completion of predefined critical steps. There was significant improvement in knowledge (P = .005), confidence (P simulation-based training to the standard didactic curriculum for all procedures. This study suggests that the addition of low-fidelity simulation-based training to a standard didactic-based curriculum is beneficial in improving resident knowledge, confidence, and tested performance of common CT-guided procedures.

The use of swine for teaching purposes in medicine and surgery has largely increased in recent years. Detailed knowledge of the porcine anatomy and physiology is a prerequisite for proper use of pigs as a teaching or an experimental model in interventional radiology. A systematic study of the radiological anatomy was undertaken in more than 100 female pigs aged 6-8 weeks. All studies were performed under general anesthesia in a single session. Animals were sacrificed at the end of the study. Selective angiographies were systematically obtained in all anatomical territories. In other animals CT and MRI examinations were performed and were correlated to anatomical sections and acrylic casts of the vascular structures. Endoscopical examinations of the upper gastrointestinal tract, including retrograde opacification of the biliary and pancreatic ducts, were added in selected animals. The main angiographic aspects of the brain, head and neck, thorax, abdomen, and pelvis were recorded. Similarities and differences in comparison with human anatomy are stressed. Potential applications in interventional radiology are indicated. (orig.)

Patient satisfaction, one of the main components of quality of care, is a crucial phenomenon for the overall health care delivery system. Even though a number of studies have been conducted about patient satisfaction in different health services, studies in radiology services are flimsy in Ethiopia. This study aimed at assessing patient satisfaction towards radiological service and associated factors in Hawassa University Teaching and Referral hospital. An institution based cross-sectional study was conducted among 321 adult patients presented for radiological service in the study area using stratified sampling technique. Patient satisfaction was measured using SERVQUAL (Service Quality) tool that consisted of seven items: accessibility, quality of radiological service, courtesy of radiology staff, existence of good communication with service provider and desk worker, physical environment and privacy technique. Exit interviews of patients were conducted using a structured and pretested questionnaire. Data was collected by three grade ten completed trained data collectors from May 12 to May 28, 2016. Multiple logistic regressions were used to identify independent factors associated with patient satisfaction on radiological services using SPSS version 21. The overall patient satisfaction towards radiological service was 71.6%. Satisfaction to accessibility of the service was 84.5% while it was 80.6% to courtesy of the staff. Similarly, 81.6% reported satisfied with quality of the service and 59.4% and 71% of reported satisfied with physical environment and radiological service provider respectively. On the other hand, 99.7% of the respondents were dissatisfied with privacy of the service. The study revealed that patients who attended primary school (AOR = 0.317, 95% CI: 0.11-0.88), unemployed patients (AOR = 0.067, 95% CI: 0.007-0.622) and patients who had short waiting time to enter into examination room less than one hour (AOR = 4.12, 95% CI: 1.4-11.62) were

We have found it very challenging to integrate images from our radiology digital imaging repository into the curriculum of our local medical school. Thus, it has been difficult to convey important knowledge related to viewing and interpreting diagnostic radiology images. We sought to determine if we could create a solution for this problem and evaluate whether students exposed to this solution were able to learn imaging concepts pertinent to medical practice. We developed University of Saskatchewan Radiology Courseware (USRC), a novel interactive web application that enables preclinical medical students to acquire image interpretation skills fundamental to clinical practice. This web application reformats content stored in Medical Imaging Resource Center teaching cases for BlackBoard Learn™, a popular learning management system. We have deployed this solution for 2 successive years in a 1st-year basic sciences medical school course at the College of Medicine, University of Saskatchewan. The "courseware" content covers both normal anatomy and common clinical pathologies in five distinct modules. We created two cohorts of learners consisting of an intervention cohort of students who had used USRC for their 1st academic year, whereas the nonintervention cohort was students who had not been exposed to this learning opportunity. To assess the learning experience of the users we designed an online questionnaire and image review quiz delivered to both of the student groups. Comparisons between the groups revealed statistically significant differences in both confidence with image interpretation and the ability to answer knowledge-based questions. Students were satisfied with the overall usability, functions, and capabilities of USRC. USRC is an innovative technology that provides integration between Medical Imaging Resource Center, a teaching solution used in radiology, and a Learning Management System.

ASTM reference radiologic digital image standards

ASTM Reference Radiographs have been essential in defining industry's material defect grade levels for many years. ASTM Reference Radiographs are used extensively as even the American Society for Metals Nondestructive Inspection and Quality Control Metals Handbook, Volume 11, eighth edition refers to ASTM Standard Reference Radiographs. The recently published E 1648 Standard Reference Radiographs for Examination of Aluminum Fusion Welds is a prime example of the on-going need for these references. To date, 14 Standard Reference Radiographs have been published to characterize material defects. Standard Reference Radiographs do not adequately address film-less radiologic methods. There are differences in mediums to content with. On a computer CRT defect indications appear differently when compared to indications viewed in a radiograph on a view box. Industry that uses non-film radiologic methods of inspection can be burdened with additional time and money developing internal standard reference radiologic images. These references may be deemed necessary for grading levels of product defects. Because there are no ASTM Standard Reference Radiologic data files for addressing this need in the industry, the authors of this paper suggested implementing a method for their creation under ASTM supervision. ASTM can assure continuity to those users making the transition from analog radiographic images to digital image data by swiftly addressing the requirements for reference digital image standards. The current status and possible future activities regarding a method to create digital data files is presented in this paper summary

Medical curricula are currently being reformed in order to establish superordinated learning objectives, including, e.g., diagnostic, therapeutic and preventive competences. This requires a shifting from traditional teaching methods towards interactive and case-based teaching concepts. Conceptions, initial experiences and student evaluations of a novel radiological course Co-operative Learning In Clinical Radiology (CLICR) are presented in this article. A novel radiological teaching course (CLICR course), which combines different innovative teaching elements, was established and integrated into the medical curriculum. Radiological case vignettes were created for three clinical teaching modules. By using a PC with PACS (Picture Archiving and Communication System) access, web-based databases and the CASUS platform, a problem-oriented, case-based and independent way of learning was supported as an adjunct to the well established radiological courses and lectures. Student evaluations of the novel CLICR course and the radiological block course were compared. Student evaluations of the novel CLICR course were significantly better compared to the conventional radiological block course. Of the participating students 52% gave the highest rating for the novel CLICR course concerning the endpoint overall satisfaction as compared to 3% of students for the conventional block course. The innovative interactive concept of the course and the opportunity to use a web-based database were favorably accepted by the students. Of the students 95% rated the novel course concept as a substantial gain for the medical curriculum and 95% also commented that interactive working with the PACS and a web-based database (82%) promoted learning and understanding. Interactive, case-based teaching concepts such as the presented CLICR course are considered by both students and teachers as useful extensions to the radiological course program. These concepts fit well into competence-oriented curricula.

A practical approach for inexpensive searches of radiology report databases.

Science.gov (United States)

Desjardins, Benoit; Hamilton, R Curtis

2007-06-01

We present a method to perform full text searches of radiology reports for the large number of departments that do not have this ability as part of their radiology or hospital information system. A tool written in Microsoft Access (front-end) has been designed to search a server (back-end) containing the indexed backup weekly copy of the full relational database extracted from a radiology information system (RIS). This front end-/back-end approach has been implemented in a large academic radiology department, and is used for teaching, research and administrative purposes. The weekly second backup of the 80 GB, 4 million record RIS database takes 2 hours. Further indexing of the exported radiology reports takes 6 hours. Individual searches of the indexed database typically take less than 1 minute on the indexed database and 30-60 minutes on the nonindexed database. Guidelines to properly address privacy and institutional review board issues are closely followed by all users. This method has potential to improve teaching, research, and administrative programs within radiology departments that cannot afford more expensive technology.

Computerization of radiology departmental management using the personal computer: application in medium sized hospital

International Nuclear Information System (INIS)

Ahn, Woo Hyun

1992-01-01

The author developed a computer program for use in registration, monthly statistics, printing of reports, data storage and retrieval in the Radiology department. This program has been used in the Department of Radiology, MoonHwa Hospital since November 1990. This program was written in FoxBASE language, consisted of two independent subprograms, one installed in a registration computer without a printer and another in a reporting computer with a printer. The subprograms were designed to link their data by floppy disk. Each computer's hard disk contained permanent files for retrieval and temporary files for data input. All permanent files were indexed on several keywords including the patient's identification data. 1. Registration was performed easily and rapidly. 2. A monthly statistic was obtained simply. 3. Retrieval of the results of previous radiologic studies, printing of report, storage and indexing of data were achieved automatically. This program had merits of simple operation, large storage capacity, rapid retrieval speed, relative low price, easy adjustment for other hospitals. Therefore this program is considered to be an economic substitute for computerization of radiology departmental management in medium sized hospitals

One of the main causes of radiological accidents is the lack of knowledge in radiological protection of workers. In order to meet the needs of professionals in radiology techniques in training in industrial radiology and radiological protection, the Training Course in Industrial Radiology was created in 2009 by MAXIM, in partnership with the Casa Branca Faculty. The objective is to present the structure and methodology of teaching used in this course to reach the objectives of training professionals with solid knowledge in industrial radiology, as well as to mention the challenges of this training. For the elaboration of the study, a statistical data base and theoretical analysis of the teaching structure of the course was used. Professional training in industrial radiology is subdivided into basic, specific, practical and complementary modules, totaling a workload of 360 hours. It is noted that most of the professionals trained come from the great urban centers of the country, favoring employability in the port terminals and industries that are located in these regions. It is concluded, therefore, that it is necessary and of great importance for the growing industrial market, the formation of new professionals, mainly in cities of the interior.

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 study was performed to develop the electronic textbook (CD-rom title) about preclinical practice of oral and maxillofacial radiology, using multimedia technology with interactive environment. After comparing the three authoring methods of multimedia, i.e. programming language, multimedia authoring tool and web authoring tool, we determined the web authoring tool as an authoring method of our electronic textbook. Intel Pentium II 350 MHz IBM-compatible personal computer with 128 Megabyte RAM, Umax Powerlook flatbed scanner with transparency unit, Olympus Camedia 1400L digital camera, ESS 1686 sound card, Sony 8 mm Handycam, PC Vision 97 pro capture board, Namo web editor 3.0, Photoshop 3.0, ThumbNailer, RealPlayer 7 basic and RealProducer G2 were used for creating the text document, diagram, figure, x-ray image, video and sound files. We made use of javascripts for tree menu structure, moving text bar, link button and spread list menu and image map etc.. After creating all files and hyperlinking them, we burned out the CD-rom title with all of the above multimedia data, Netscape communicator and plug in program as a prototype. We developed the dental radiology electronic textbook which has 9 chapters and consists of 155 text documents, 26 figures, 150 x-ray image files, 20 video files, 20 sound files and 50 questions with answers. We expect that this CD-rom title can be used at the intranet and internet environments and continuous updates will be performed easily.

Radiology instruction is based on the principle that grouped (or massed) repetition of an intellectual activity leads to expertise. The aim of this study was to test the hypothesis that the spaced (or interleaved) method of teaching chest x-ray interpretation is more effective than the massed method. After institutional review board approval was obtained, 40 first- and second-year medical students were randomized into two groups matched by age, gender, and education experience. Both groups saw six examples of 12 common chest radiographic patterns, one grouped, the other scrambled randomly without repeating strings. After a distraction, participants took a multiple-choice test consisting of two cases in each radiographic pattern, one previously shown, one new. Results were analyzed using two-tailed Student's t test of proportion. Comparing interleaved and massed groups, the average overall score was 57% versus 43% (P = .03), the recollection score was 61% versus 47% (P = .03), and the induction score was 53% versus 40% (P = 0.10), respectively. Comparing second- and first-year students, average scores were 67% and 39%, respectively (P method of instruction leads to better results than the massed method across all levels of education. A higher level of medical education improves performance independent of method of instruction. Copyright © 2016 American College of Radiology. Published by Elsevier Inc. All rights reserved.

Anonymity and Electronics: Adapting Preparation for Radiology Resident Examination.

Chapman, Teresa; Reid, Janet R; O'Conner, Erin E

2017-06-01

Diagnostic radiology resident assessment has evolved from a traditional oral examination to computerized testing. Teaching faculty struggle to reconcile the differences between traditional teaching methods and residents' new preferences for computerized testing models generated by new examination styles. We aim to summarize the collective experiences of senior residents at three different teaching hospitals who participated in case review sessions using a computer-based, interactive, anonymous teaching tool, rather than the Socratic method. Feedback was collected from radiology residents following participation in a senior resident case review session using Nearpod, which allows residents to anonymously respond to the teaching material. Subjective resident feedback was uniformly enthusiastic. Ninety percent of residents favor a case-based board review incorporating multiple-choice questions, and 94% favor an anonymous response system. Nearpod allows for inclusion of multiple-choice questions while also providing direct feedback to the teaching faculty, helping to direct the instruction and clarify residents' gaps in knowledge before the Core Examination.

The written radiological report is the most important means of communication between the radiologist and the referring medical doctor. There is no universal definition of a radiological report concerning its structure and content. The majority of clinicians and radiologists prefer structured reporting rather than free text reports of findings. Structured reporting does not increase the quality of a radiological report but has many advantages in research, teaching and quality management. Using standard RadLex terms facilitates translation and ontological assignment of a report. The Reporting Initiative of the Radiological Society of North America (RSNA) offers free and freely available extensively validated best practices radiology report templates in the new management of radiology report templates (MRRT) format according to the guidelines of the Integrating the Healthcare Enterprise (IHE).

During the past four years the authors have been gaining experince in reporting radiological examinations by personal computer. Today they describe the project of a new software which allows the reporting and filing of roentgenograms. This program was realized by a radiologist, using a well known data base management system: dBASE III. The program was shaped to fit the radiologist's needs: it helps to report, and allows to file, radiological data, with the diagnosic codes used by the American College of Radiology. In this paper the authors describe the data base structure and indicate the software functions which make its use possible. Thus, this paper is not aimed at advertising a new reporting program, but at demonstrating how the radiologist can himself manage some aspects of his work with the help of a personal computer

Teaching Communication Skills to Radiology Residents.

Science.gov (United States)

Itri, Jason N; Yacob, Sammy; Mithqal, Ayman

The transition of health care in the United States from volume to value requires a systems-based approach aligning clinical services across the continuum of care. The ability to communicate effectively and resolve conflict is a critical skill within the systems-based model. Recognizing the essential role of communication in medicine, the Accreditation Council of Graduate Medical Education has designated interpersonal and communication skills a core competency for all residents regardless of specialty. Yet, communication skills are often developed through on-the-job training or not at all. Traditional educational curricula use a predominantly didactic approach without opportunities for trainees to observe, actively experiment, or reflect on what is learned as a part of the learning process. In this article, we describe a 1-day experiential communication skills workshop customized for radiology residents that consists of Myers-Briggs Type Indicator and conflict management sessions designed to develop interpersonal, communication, and conflict management skills through group discussion, role-play, and simulation. The purpose of this educational initiative was to determine the perceived value of an experiential communication skills workshop designed for radiology trainees. Copyright © 2017 Elsevier Inc.

The use of interventional radiology procedures has considerably increased in recent years, as has the number of related medicolegal litigations. This study aimed to highlight the problems underlying malpractice claims in interventional radiology and to assess the importance of the informed consent process. The authors examined all insurance claims relating to presumed errors in interventional radiology filed by radiologists over a period of 14 years after isolating them from the insurance database of all radiologists registered with the Italian Society of Medical Radiology (SIRM) between 1 January1993 and 31 December 2006. In the period considered, 98 malpractice claims were filed against radiologists who had performed interventional radiology procedures. In 21 cases (21.4%), the event had caused the patient's death. In >80% of cases, the event occurred in a public facility. The risk of a malpractice claim for a radiologist practising interventional procedures is 47 per 1,000, which corresponds to one malpractice claim for each 231 years of activity. Interventional radiology, a discipline with a biological risk profile similar to that of surgery, exposes practitioners to a high risk of medicolegal litigation both because of problems intrinsic to the techniques used and because of the need to operate on severely ill patients with compromised clinical status. Litigation prevention largely depends on both reducing the rate of medical error and providing the patient with correct and coherent information. Adopting good radiological practices, scrupulous review of procedures and efficiency of the instruments used and audit of organisational and management processes are all factors that can help reduce the likelihood of error. Improving communication techniques while safeguarding the patient's right to autonomy also implies adopting clear and rigorous processes for obtaining the patient's informed consent to the medical procedure.

Atomic energy-related laws in Korea have a two pronged management system for radiological accidents. To be specific, the Atomic Energy Act is applicable to all radiological accidents, i.e. accidents pertaining to nuclear facilities and radioactive materials while the Act for Physical Protection and Radiological Emergency ('APPRE') applies to accidents related to nuclear materials and large-scale nuclear facilities. The Atomic Energy Act contains three provisions directly related with radiological accidents (Articles 89, 98 and 102). Article 89 provides for the obligations of nuclear licensees or consigned transporters to institute safety measures and file a report to the head of the Ministry of Education, Science and Technology ('MEST') in the event of any radiological accident during transport or packing of radioactive materials, etc. Article 98 stipulates obligations of nuclear licensees to implement safety procedures and submit a report to the Minister of Education, Science and Technology concerning radiation hazards arising in the event a radiological accident occurs in connection with nuclear projects, as well as the Minister's requests to implement necessary measures. Article 102 explicitly provides for obligations to file a report to the Minister in the event of theft, loss, fire or other accidents involving radioactive materials, etc. in the possession of nuclear licensees. The APPRE classifies radiological accidents according to location and scale of the accidents. Based on location, accidents are divided into accidents inside or outside nuclear facilities. Accidents inside nuclear facilities refer to accidents that occur at nuclear reactors, nuclear fuel cycling facilities, radioactive waste storage, treatment and disposal facilities, facilities using nuclear materials and facilities related to radioisotopes of not lower than 18.5PBq (Subparagraph 2, Article 2 of the APPRE) while accidents outside nuclear facilities mean accidents

Film reject analysis and image quality in diagnostic Radiology Department of a Teaching hospital in Ghana

Directory of Open Access Journals (Sweden)

2014-10-01

Full Text Available Patients usually undergo repeated X-ray examinations after their initial X-ray radiographs are rejected due to poor image quality. This subjects the patients to an excess radiation exposure and extra cost and necessitates the need to investigate the causes of reject. The use of reject analysis as part of the overall quality assurance programs in clinical radiography and radiology services is vital in the evaluation of image quality of a well-established practice. It is shown that, in spite of good quality control maintained by the Radiology Department of a Teaching hospital in Ghana, reject analysis performed on a number of radiographic films developed indicated 14.1% reject rate against 85.9% accepted films. The highest reject rate was 57.1 ± 0.7% which occurs in cervical spine and the lowest was7.7 ± 0.5% for lumbar spine. The major factors contributing to film rejection were found to be over exposure and patient positioning in cervical spine examinations. The most frequent examination was chest X-ray which accounts for about 42.2% of the total examinations. The results show low reject rates by considering the factors for radiographic rejection analysis in relation to both equipment functionality and film development in the facility.

The creation and maintenance of radiology teaching materials is both laborious and very time-consuming, but at a teaching hospital is important. Through use of the technology offered by today's worldwide web, this problem can be efficiently solved, and on this basis, we devised a multimedia radiology self-learning course for abdominal ultrasound and CT. A combination of video and audio tapes has been used as teaching material; the authors digitized and converted these to Hypertext Mark-up Language (HTML) format. films were digitized with a digital camera and compressed to joint photographic expert group (JPEG) format, while audio tapes were digitized with a sound recorder and compressed to real audio format. Multimedia on the worldwide web will facilitate easy management and maintenance of a self-learning course. To make this more suitable for practical use, continual upgrading on the basis of experience is needed. (author). 3 refs., 4 figs

Desktop computer hardware and software provide many new and accessible avenues for increased academic productivity, but some activities may have legal implications. The advent of technologies such as scanners, the ever-increasing number of electronic bulletin boards, and the development of the "information superhighway" affect the concept of copyright and require authors and publishers to reconsider their legal rights and obligations when they create or publish new works or modify existing ones. For example, with desktop scanners, almost any image, published or otherwise, can be copied, enhanced, and manipulated. Moreover, many radiologists have access to copyrighted digital radiologic teaching file images, such as those from the University of Iowa or the University of Washington, which are available (and "downloadable") on the Internet. Because "downloading" (or "uploading") a document or image is essentially making a copy of that document or image, copyright laws and the rights that they afford authors are involved.

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.)

Teaching is an important skill. Academic physicians teach on a daily basis, and nearly all physicians occasionally teach colleagues and patients. There are generally few opportunities for medical students to learn teaching skills. We developed a novel "near-peer" teaching program in which fourth-year students cotaught first-year students. Eighteen fourth-year students enrolled in our institution's primary senior radiology elective learned the basics of ultrasound through a series of lectures and hands-on scanning sessions. Each fourth-year student, paired with a radiology resident or attending, then cotaught a first-year anatomy small group session. After instruction, voluntary surveys were administered to assess the perceived value of the "near-peer" teaching experience. Seventeen of 18 (94%) and 104 of 120 (87%) administered surveys were returned by fourth- and first-year students, respectively. Sixteen (94%) and 99 (95%) of the fourth- and first-year students reported they "enjoyed" or "really enjoyed" the near-peer teaching experience. Fourteen (82%) of the fourth years perceived improvement in their teaching skills and an increase in their knowledge. Only 8 (47%) of the fourth years thought they were "helpful" or "very helpful," though 92 (88%) of the first years identified their fourth-year co-instructors as "helpful" or "very helpful." We piloted a novel "near-peer" program. Both senior and freshman students enjoyed the experience, and fourth years thought the session was educational for them as well. Although most fourth years did not judge themselves as helpful, first-year students overwhelmingly considered them a useful addition to the session. Copyright © 2013 AUR. Published by Elsevier Inc.

Romero Acosta, A.; Gutierrez Lores, S.

2015-01-01

Calibration of dosimeters for diagnostic radiology includes current and charge measurements, which are often repetitive. However, these measurements are usually done using modern electrometers, which are equipped with an RS-232 interface that enables instrument control from a computer. This paper presents an automated system aimed to the measurements for the calibration of dosimeters used in diagnostic radiology. A software application was developed, in order to achieve the acquisition of the electric charge readings, measured values of the monitor chamber, calculation of the calibration coefficient and issue of a calibration certificate. A primary data record file is filled and stored in the computer hard disk. The calibration method used was calibration by substitution. With this system, a better control over the calibration process is achieved and the need for human intervention is reduced. the automated system will be used in the calibration of dosimeters for diagnostic radiology at the Cuban Secondary Standard Dosimetry Laboratory of the Center for Radiation Protection and Hygiene.

Information on radiation hazard and on radiological protection in medical school in Italy

International Nuclear Information System (INIS)

Biagini, C.

1993-01-01

The state of teaching Radiation Protection in Medical School in Italy was considered. An historical approach was utilized, in order to define periods of time characterized by different conditions. Some data are collected by a concise enquiry on the information given during the course of Radiology in the second triennial cycle, and on some other teaching courses including information on radiation effects. The conclusion is that teaching times are exceedingly reduced, and the need of improving the diffusion of knowledge in the field is stressed. An official Act of the OECD and of European Community is expected, with the aim of emphasizing the importance of the information of doctors on Radiation Protection as a problem of public interest. A proposal is advanced of implementing the Teaching of Radiobiology in the second triennial cycle, changing the name of the course in 'Radiobiology and Radiological Protection'. 6 tabs

Third volume of a trilogy devoted to radiology education and improvement of medical imaging students' learning, teaching, and scholarship. Reviews the philosophies, theories, and principles that underpin assessment and evaluation in radiology education. Includes a series of rich case studies. Written by an international group of experienced educators and medical professionals. This book reviews the philosophies, theories, and principles that underpin assessment and evaluation in radiology education, highlighting emerging practices and work done in the field. The sometimes conflicting assessment and evaluation needs of accreditation bodies, academic programs, trainees, and patients are carefully considered. The final section of the book examines assessment and evaluation in practice, through the development of rich case studies reflecting the implementation of a variety of approaches. This is the third book in a trilogy devoted to the scholarship of radiology education and is the culmination of an important initiative to improve medical imaging students' learning, teaching, and scholarship by bringing together experienced educators and medical professionals. The previous two books focused on the culture and the learning organizations in which our future radiologists are educated and on the application of educational principles in the education of radiologists. Here, the trilogy comes full circle: attending to the assessment and evaluation of the education of its members has much to offer back to the learning of the organization.

Wertz, Christopher Ira; Hobbs, Dan L; Mickelsen, Wendy

2014-01-01

To review the existing literature pertaining to the current learning technologies available in radiologic science education and how to implement those technologies. Only articles from peer-reviewed journals and scholarly reports were used in the research for this review. The material was further restricted to those articles that emphasized using new learning technologies in education, with a focus on radiologic science education. Teaching in higher education is shifting from a traditional classroom-based lecture format to one that incorporates new technologies that allow for more varied and diverse educational models. Radiologic technology educators must adapt traditional education delivery methods to incorporate current technologies. Doing so will help engage the modern student in education in ways in which they are already familiar. As students' learning methods change, so must the methods of educational delivery. The use of new technologies has profound implications for education. If implemented properly, these technologies can be effective tools to help educators.

Effective and dedicated educators are critical to the preservation and advancement of the practice of radiology. The need for innovative and adaptable educators is increasingly being recognized, with several institutions granting academic promotions through clinician-educator tracks. The implementation of resident "clinician-educator tracks" or "teaching tracks" should better prepare residents aspiring to become academic radiologists focused on teaching. In this work, we describe our experience in the development and implementation of a clinician-educator track for diagnostic radiology residents at our institution.

Francisco Sendra Portero

2010-07-01

Full Text Available Since 1998, radiology teaching and learning electronic resources have been developed at the University of Málaga. Some experiences on undergraduate radiology education are presented in this paper: a self-conducted training on radiology called “A Walk through Radiology”, some projects to create and develop radiology consulting tools, a project about audio-recorded virtual lectures (AMERAM, started on 2005, and a Web portal to collect radiology education Internet resources. Finally, we conclude with some reflections about the experience along these years, which has contributed to improve the student’s radiology learning in our centre and has supplied educative tools to students and postgraduates of this and other cities. We consider that the European Space of Higher Education learning philosophy, student centered and self-learning based, gives a vital role to undergraduate electronic education tools.

Computerization of reporting and data storage using automatic coding method in the department of radiology

1990-10-15

The authors developed a computer program for use in printing report as well as data storage and retrieval in the Radiology department. This program used IBM PC AT and was written in dBASE III plus language. The automatic coding method of the ACR code, developed by Kim et al was applied in this program, and the framework of this program is the same as that developed for the surgical pathology department. The working sheet, which contained the name card for X-ray film identification and the results of previous radiologic studies, were printed during registration. The word precessing function was applied for issuing the formal report of radiologic study, and the data storage was carried out during the typewriting of the report. Two kinds of data files were stored in the hard disk ; the temporary file contained full information and the permanent file contained patient's identification data, and ACR code. Searching of a specific case was performed by chart number, patients name, date of study, or ACR code within a second. All the cases were arranged by ACR codes of procedure code, anatomy code, and pathology code. Every new data was copied to the diskette after daily work automatically, with which data could be restored in case of hard diskette failure. The main advantage of this program with comparison to the larger computer system is its low price. Based on the experience in the Seoul District Armed Forces General Hospital, we assume that this program provides solution to various problems in the radiology department where a large computer system with well designed software is not available.

2011-01-01

Purpose: To evaluate current applications of e-learning in radiology. Material and methods: A Medline search was performed using PubMed (National Library of Medicine, Bethesda, MD) for publications discussing the applications of e-learning in radiology. The search strategy employed a single combination of the following terms: (1) e-learning, and (2) education and (3) radiology. This review was limited to human studies and to English-language literature. We reviewed all the titles and subsequent the abstract of 29 articles that appeared pertinent. Additional articles were identified by reviewing the reference lists of relevant papers. Finally, the full text of 38 selected articles was reviewed. Results: Literature data shows that with the constant development of technology and global spread of computer networks, in particular of the Internet, the integration of multimedia and interactivity introduced into electronic publishing has allowed the creation of multimedia applications that provide valuable support for medical teaching and continuing medical education, specifically for radiology. Such technologies are valuable tools for collaboration, interactivity, simulation, and self-testing. However, not everything on the World Wide Web is useful, accurate, or beneficial: the quality and veracity of medical information on the World Wide Web is variable and much time can be wasted as many websites do not meet basic publication standards. Conclusion: E-learning will become an important source of education in radiology.

Purpose. Analyzing the availability and the contents of the internet homepages of the radiological departments of German universities.Material and method. In June and July 2001 the internet homepages of 36 radiological departments of German universities were evaluated in a study. A medical student experienced in using the world wide web examined the websites concerning the following criteria: research, teaching, informations for patients, clinical topics and general information. Additionally an evaluation of the technical standard of the presentation was performed.Results. 31 of the 36 radiological departments presented a homepage in the world wide web. The subject research was presented by 29 institutes. Also 29 departments provided information concerning teaching in their presentations. In 24 cases informations especially for patients were given. In all topics there is a huge variety of the quality and quantity of the provided information throughout the different institutions. 21 homepages available without restriction during the study period; 3 were nearly completely under construction. Multimedia techniques were only used in 2 homepages. The structural hierarchy of the webpages was in the average only two or three levels. Only 6 providers presented an additional version of their homepage in english.Conclusion. In the moment the possibility of internet-presentation is sub-optimal used by the responsible persons of the radiological institutions. The main emphasis is on research and teaching. There is nearly no use of multimedial elements in the presentations. Only a minority of the homepages can be read by international viewers because of the lack of an english version of the pages.

To assess the time needed and the resulting effects of a complete digitalisation of a radiological department of a major hospital (856 beds, 28,000 in-patients, 35,000 out-patients/year) a pilot study was performed. This had to be done without interrupting routine services. After intensive preparations were performed and the hospital-network was completed, within a two year period all radiological functions (mammography excluded), reporting stations and archives were changed to a complete digital workflow. All modalities (provided by 3 different companies) are now connected by DICOM-work lists. The picture-files (4 GB/day) are automatically routed to the work-stations (n = 10), where the reporting and file shows are performed, to the digital archive and to the peripheral viewing-stations (n = 44). The distribution of the digital pictures takes place all over the hospital including the ORs and special units. We accomplished, to connect electronically the report and the image data. The clinical file shows are also performed completely digitally. The access to the data of the deep archive is possible by the dept. of radiology without any manual interaction. The film consumption was reduced to an amount of less than 10%, as compared to the prior PACS situation. Since PACS has been introduced the radiological productivity increased by more than 15% and throughput-time was clearly reduced. The complete digitalisation increases productivity and attractiveness of a hospital-radiology and helps to shorten diagnostic and therapeutic decision-making. The transfer from a conventional to a digital workflow is possible without interrupting the clinical services. Extensive preparations and ongoing assistance of such projects though are clearly needed.

A preliminary audit of orders for computed tomography was performed to evaluate the typical performance of interns ordering radiologic examinations. According to the audit, the interns showed only minimal improvement after 8 months of work experience. The online radiology ordering module (ROM) program included baseline assessment of student performance (part I), online learning with the ROM (part II), and follow-up assessment of performance with simulated ordering with the ROM (part III). A curriculum blueprint determined the content of the ROM program, with an emphasis on practical issues, including provision of logistic information, clinical details, and safety-related information. Appropriate standards were developed by a committee of experts, and detailed scoring systems were devised for assessment. The ROM program was successful in addressing practical issues in a simulated setting. In the part I assessment, the mean score for noting contraindications for contrast media was 24%; this score increased to 59% in the part III assessment (P = .004). Similarly, notification of methicillin-resistant Staphylococcus aureus status and pregnancy status and provision of referring physician contact information improved significantly. The quality of the clinical notes was stable, with good initial scores. Part III testing showed overall improvement, with the mean score increasing from 61% to 76% (P radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

Teaching the Healthcare Economics Milestones to Radiology Residents: Our Pilot Curriculum Experience.

Science.gov (United States)

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.

This volume describes in detail radiological examinations of the skeleton modern procedures in orthopaedic surgery. Special emphasis is given to functional examination techniques based upon the authors' extensive work on standardized radiological examinations best suited to the needs of orthopaedic surgeons. These techniques were developed at the Radiodiagnostic Department of the Central Radiological Clinic, Bern University, in cooperation with the University Clinic of Orthopaedics and Surgery of the Locomotor System. Exposure techniques are explained concisely, yet with extraordinary precision and attention to detail. They have proved highly successful in teaching programs for X-ray technicians and as standard examination techniques for many hospitals, X-ray departments, orthopaedic units, and private clinics. Recommended for orthopaedic surgeons, radiologists, general surgeons, and X-ray technicians, this definitive treatise, with its superb X-ray reproductions and complementary line drawings, explains how to achieve improved diagnoses and standardized control with the least possible radiation exposure to the patient

In general, medical students lack the core knowledge that is needed for good-quality ordering of radiology services, and the experience typically afforded to interns does not address this lack of knowledge. The ROM program was a successful intervention that resulted in statistically significant improvements in the quality of radiologic examination orders, particularly with regard to logistic and radiation safety issues.

The changing healthcare environment challenges the traditional role of academic medicine. Pediatric radiologists involved in research, education and teaching are under pressure to forego such endeavors in favor of increased clinical responsibilities. How we perform research must change if our subspecialty is to survive into the future, as we cannot afford to give up our traditional duties as researchers and educators. To do so could summon the beginning of the end for pediatric radiology. Rather, we must begin the process of restructuring research in pediatric radiology to take into account the efficient use of our resources which provide the greatest return on our investment.

ESR paper on the proper use of mobile devices in radiology.

Science.gov (United States)

2018-04-01

Mobile devices (smartphones, tablets, etc.) have become key methods of communication, data access and data sharing for the population in the past decade. The technological capabilities of these devices have expanded very rapidly; for example, their in-built cameras have largely replaced conventional cameras. Their processing power is often sufficient to handle the large data sets of radiology studies and to manipulate images and studies directly on hand-held devices. Thus, they can be used to transmit and view radiology studies, often in locations remote from the source of the imaging data. They are not recommended for primary interpretation of radiology studies, but they facilitate sharing of studies for second opinions, viewing of studies and reports by clinicians at the bedside, etc. Other potential applications include remote participation in educational activity (e.g. webinars) and consultation of online educational content, e-books, journals and reference sources. Social-networking applications can be used for exchanging professional information and teaching. Users of mobile device must be aware of the vulnerabilities and dangers of their use, in particular regarding the potential for inappropriate sharing of confidential patient information, and must take appropriate steps to protect confidential data. • Mobile devices have revolutionized communication in the past decade, and are now ubiquitous. • Mobile devices have sufficient processing power to manipulate and display large data sets of radiological images. • Mobile devices allow transmission & sharing of radiologic studies for purposes of second opinions, bedside review of images, teaching, etc. • Mobile devices are currently not recommended as tools for primary interpretation of radiologic studies. • The use of mobile devices for image and data transmission carries risks, especially regarding confidentiality, which must be considered.

Ethics in radiology: wait lists queue jumping.

Education in ethics is a requirement for all Royal College residency training programs as laid out in the General Standards of Accreditation for residency programs in Canada. The ethical challenges that face radiologists in clinical practice are often different from those that face other physicians, because the nature of the physician-patient interaction is unlike that of many other specialties. Ethics education for radiologists and radiology residents will benefit from the development of teaching materials and resources that focus on the issues that are specific to the specialty. This article is intended to serve as an educational resource for radiology training programs to facilitate teaching ethics to residents and also as a continuing medical education resource for practicing radiologists. In an environment of limited health care resources, radiologists are frequently asked to expedite imaging studies for patients and, in some respects, act as gatekeepers for specialty care. The issues of wait lists, queue jumping, and balancing the needs of individuals and society are explored from the perspective of a radiologist. Copyright © 2013 Canadian Association of Radiologists.

Purpose: evaluation of an interactive, multimedia case-based learning platform for the radiological education of medical students. Materials and methods: an interactive electronic learning platform for the education of medical students was built in html format independent of the operating system in the context of the Heidelberg Curriculum Medicinale (HeiCuMed). A case collection of 30 common and authentic clinical cases is used as the central theme and clinical background. The user has to work on each case by making decisions regarding a selection of diagnostic modalities and by analyzing the chosen studies. After a reasonable selection and sequence of diagnostic radiological modalities and their interpretation, a diagnosis has to be made. An extensive collection of normal findings for any modality is available for the user as a reference in correlation with the pathology at anytime within each case. The case collection consists of 2053 files with 1109 Internet pages (html) and 869 image files (jpeg) with approximately 10 000 crosslinks (links). The case collection was evaluated by a questionnaire (scale 1 - 5) at the end of the radiological student course. The development of the results of the radiological course exam was analyzed to investigate any effect on the learning performance after the case collection was introduced. Results: 97.6% of the course participants would use the case collection beyond the radiological student course to learn radiology in their medical studies. The handling of the case collection was rated excellent in 36.9%, good in 54.6%, satisfactory in 8% and unsatisfactory in 0.4%. 41% felt that the case collection was overall excellent, 49.2% good, 7.8% satisfactory, 1.6% unsatisfactory and 0.4% poor. A positive trend in the development of the results in the radiological course exam with less variance after the introduction of the case collection was found but failed statistical significance.

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

2014-01-01

Radiologic science programs continue to adopt the use of blended online education in their curricula, with an increase in the use of online courses since 2009. However, perceived barriers to the use of online education formats persist in the radiologic science education community. An electronic survey was conducted to explore the current status of online education in the radiologic sciences and to identify barriers to providing online courses. A random sample of 373 educators from radiography, radiation therapy, and nuclear medicine technology educational programs accredited by the Joint Review Committee on Education in Radiologic Technology and Joint Review Committee on Educational Programs in Nuclear Medicine Technology was chosen to participate in this study. A qualitative analysis of self-identified barriers to online teaching was conducted. Three common themes emerged: information technology (IT) training and support barriers, student-related barriers, and institutional barriers. Online education is not prevalent in the radiologic sciences, in part because of the need for the clinical application of radiologic science course content, but online course activity has increased substantially in radiologic science education, and blended or hybrid course designs can effectively provide opportunities for student-centered learning. Further development is needed to increase faculty IT self-efficacy and to educate faculty regarding pedagogical methods appropriate for online course delivery. To create an excellent online learning environment, educators must move beyond technology issues and focus on providing quality educational experiences for students.

University of California San Francisco automated radiology department system-without picture archival and communication system (PACS)

Science.gov (United States)

Quintin, June A.; Simborg, Donald W.

1982-01-01

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

[No exchange of information without technology : modern infrastructure in radiology].

Hupperts, H; Hermann, K-G A

Modern radiology cannot accomplish the daily numbers of examinations without supportive technology. Even though technology seems to be becoming increasingly more indispensable, business continuity should be ensured at any time and if necessary even with a limited technical infrastructure by business continuity management. An efficient information security management system forms the basis. The early radiology information systems were islands of information processing. A modern radiology department must be able to be modularly integrated into an informational network of a bigger organization. The secondary use of stored data for clinical decision-making support poses new challenges for the integrity of the data or systems because medical knowledge is displayed and provided in a context of treatment. In terms of imaging the creation and distribution radiology services work in a fully digital manner which is often different for radiology reports. Legally secure electronic diagnostic reports require a complex technical infrastructure; therefore, diagnostic findings still need to be filed as a paper document. The internal exchange and an improved dose management can be simplified by systems which continuously and automatically record the doses and thus provide the possibility of permanent analysis and reporting. Communication between patient and radiologist will gain ongoing importance. Intelligent use of technology will convey this to the radiologist and it will facilitate the understanding of the information by the patient.

Purpose. To increase the quality of internal and external interactions (patients, clinical colleagues, technicians, radiologists) in a department of radiology.Method. Accompanied by a well-experienced adviser workshops have been performed dealing with different topics like ''contact to patients'', ''performance of the radiological report and interaction with the referring colleague'' or ''research and teaching''. A catalogue of different actions was defined to reduce hindrances within the internal and external work-flow.Results. A total number of 53 actions was defined and related to different persons who were responsible for the realisation of the measures within a time interval. Six months after starting the quality management 46 (86%) of the defined actions were realised successfully, and another 4 (8%) measures were still running. There was a moderate increase of satisfaction of the patients and clinical colleagues considering the waiting time.Conclusions. A quality management in a radiological department allows an optimisation of the internal and external interactions. However, the guidance of a well-experienced adviser is as essential as the continuous control of successful finished measures. (orig.) [de

2011-01-01

Quantitative and descriptive imaging data are a vital component of the radiology report and are frequently of paramount importance to the ordering physician. Unfortunately, current methods of recording these data in the report are both inefficient and error prone. In addition, the free-text, unstructured format of a radiology report makes aggregate analysis of data from multiple reports difficult or even impossible without manual intervention. A structured reporting work flow has been developed that allows quantitative data created at an advanced imaging workstation to be seamlessly integrated into the radiology report with minimal radiologist intervention. As an intermediary step between the workstation and the reporting software, quantitative and descriptive data are converted into an extensible markup language (XML) file in a standardized format specified by the Annotation and Image Markup (AIM) project of the National Institutes of Health Cancer Biomedical Informatics Grid. The AIM standard was created to allow image annotation data to be stored in a uniform machine-readable format. These XML files containing imaging data can also be stored on a local database for data mining and analysis. This structured work flow solution has the potential to improve radiologist efficiency, reduce errors, and facilitate storage of quantitative and descriptive imaging data for research.

2017-06-01

The American Board of Radiology Core Examination integrates assessment of physics knowledge into its overall testing of clinical radiology, with an emphasis on understanding image quality and artifacts, radiation dose, and patient safety for each modality or subspecialty organ system. Accordingly, achieving a holistic approach to physics education of radiology residents is a huge challenge. The traditional teaching of radiological physics-simply through didactic lectures-was not designed for such a holistic approach. Admittedly, time constraints and clinical demands can make incorporation of physics teaching into clinical practice problematic. We created and implemented a week-long, intensive physics rotation for fledgling radiology residents and evaluated its effectiveness. The dedicated physics rotation is held for 1 week during the first month of radiology residency. It comprises three components: introductory lectures, hands-on practical clinical physics operations, and observation of clinical image production. A brief introduction of the physics pertinent to each modality is given at the beginning of each session. Hands-on experimental demonstrations are emphasized, receiving the greatest allotment of time. The residents perform experiments such as measuring radiation dose, studying the relationship between patient dose and clinical practice (eg, fluoroscopy technique), investigating the influence of acquisition parameters (kV, mAs) on radiographs, and evaluating image quality using computed tomography, magnetic resonance imaging, ultrasound, and gamma camera/single-photon emission computed tomography/positron emission tomography phantoms. Quantitative assessment of the effectiveness of the rotation is based on an examination that tests the residents' grasp of basic medical physics concepts along with written course evaluations provided by each resident. The pre- and post-rotation tests show that after the physics rotation, the average correct score of 25

Informatics in Radiology (infoRAD): personal computer security: part 2. Software Configuration and file protection.

Caruso, Ronald D

2004-01-01

Proper configuration of software security settings and proper file management are necessary and important elements of safe computer use. Unfortunately, the configuration of software security options is often not user friendly. Safe file management requires the use of several utilities, most of which are already installed on the computer or available as freeware. Among these file operations are setting passwords, defragmentation, deletion, wiping, removal of personal information, and encryption. For example, Digital Imaging and Communications in Medicine medical images need to be anonymized, or "scrubbed," to remove patient identifying information in the header section prior to their use in a public educational or research environment. The choices made with respect to computer security may affect the convenience of the computing process. Ultimately, the degree of inconvenience accepted will depend on the sensitivity of the files and communications to be protected and the tolerance of the user. Copyright RSNA, 2004

The computer-based tutoring of visual concepts such as radiological images is a largely unexplored area. A review of the literature highlights limited use of computers as a means of radiological education, with the majority of systems being little more than hypermedia prototypes, on-line teaching files, and passive CD-Roms. Very few of the systems discussed in the research literature draw on the work from cognitive science and educational psychology for tutoring visual concepts. This thesis details and evaluates a method for indexing and retrieving images from large image databases via a cognitively informed graphical representation of visual concepts. This representation is derived using Multiple Correspondence Analysis from a statistical analysis of features present in the images. It is intended that this representation be used to assist in the computer based teaching of any discipline that requires the tutoring of visual concepts. The domain used as a test bed for this research is Magnetic Resonance Imaging in neuroradiology. Tutoring the interpretation of MR scans of the head represents a real practical problem due to the inherent complexity of the brain and variations in tissue contrast within image sequence and disease/pathology. The literature of concept categorisation and representation is critically reviewed to inform the design of a graphical representation of a concept (a pathology in the application domain). A specification for the design of an explicit representation of visual concepts is drawn from this literature review, together with methods of tutoring based around this model. A methodology for producing this representation is described, and implemented in the development of an overview plot for the concept of a disease of the brain, with associated statistical measures derived and operationalised for typicality and similarity of cases within a disease.

AIM: To assess medical emergency radiology referral practice compared with a set of French guidelines and to measure the efficiency of computer-based guidelines on unnecessary medical imaging. MATERIALS AND METHODS: All radiological requests were computerized in the medical emergency departments of two French teaching hospitals. During control periods, radiological requests were recorded but no action was taken. During intervention periods, reminder displays on screen indicated the appropriate recommendations. Three control and three intervention periods of 1 month each were conducted. The percentage of requests that did not conform to the guidelines and variation related to periods of control and intervention were measured. RESULTS: The proportion of requests that did not conform to the guidelines was 33{center_dot}2% when the guidelines were inactive and decreased to 26{center_dot}9% when the recommendations were active (P < 0{center_dot}0001). The three imaging examinations (chest radiographs, abdominal plain radiographs and CT of the brain) accounted for more than 80% of all requests; more than 50% of abdominal plain radiographs requests did not conform with recommendations while this percentage was respectively 24{center_dot}9% and 15{center_dot}8% for chest radiographs and computed tomography (CT) of the brain. Seven situations accounted for 70% of non-conforming radiological referrals; in these situations, junior practitioners' knowledge was inadequate. CONCLUSION: While the computer provided advice that was tailored to the needs of individual patients, concurrent with care, the effect of our intervention was weak. However, our study identified the few situations that were responsible for the majority of unnecessary radiological requests; we expect that this result could help clinicians and radiologists to develop more specific actions for these situations.

The three imaging examinations (chest radiographs, abdominal plain radiographs and CT of the brain) accounted for more than 80% of all requests; more than 50% of abdominal plain radiographs requests did not conform with recommendations while this percentage was respectively 24·9% and 15·8% for chest radiographs and computed tomography (CT) of the brain. Seven situations accounted for 70% of non-conforming radiological referrals; in these situations, junior practitioners' knowledge was inadequate. CONCLUSION: While the computer provided advice that was tailored to the needs of individual patients, concurrent with care, the effect of our intervention was weak. However, our study identified the few situations that were responsible for the majority of unnecessary radiological requests; we expect that this result could help clinicians and radiologists to develop more specific actions for these situations.

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

Eye tracking research has been conducted for decades to gain understanding of visual diagnosis such as in radiology. For educational purposes, it is important to identify visual search patterns that are related to high perceptual performance and to identify effective teaching strategies. This review of eye-tracking literature in the radiology domain aims to identify visual search patterns associated with high perceptual performance. Databases PubMed, EMBASE, ERIC, PsycINFO, Scopus and Web of Science were searched using 'visual perception' OR 'eye tracking' AND 'radiology' and synonyms. Two authors independently screened search results and included eye tracking studies concerning visual skills in radiology published between January 1, 1994 and July 31, 2015. Two authors independently assessed study quality with the Medical Education Research Study Quality Instrument, and extracted study data with respect to design, participant and task characteristics, and variables. A thematic analysis was conducted to extract and arrange study results, and a textual narrative synthesis was applied for data integration and interpretation. The search resulted in 22 relevant full-text articles. Thematic analysis resulted in six themes that informed the relation between visual search and level of expertise: (1) time on task, (2) eye movement characteristics of experts, (3) differences in visual attention, (4) visual search patterns, (5) search patterns in cross sectional stack imaging, and (6) teaching visual search strategies. Expert search was found to be characterized by a global-focal search pattern, which represents an initial global impression, followed by a detailed, focal search-to-find mode. Specific task-related search patterns, like drilling through CT scans and systematic search in chest X-rays, were found to be related to high expert levels. One study investigated teaching of visual search strategies, and did not find a significant effect on perceptual performance. Eye

Full Text Available Abstract Background Following implementation of Modernising Medical Careers (MMC in the UK, potential radiology trainees must decide on their career and apply sooner than ever before. We aimed to determine whether current trainees were sufficiently informed to make an earlier career decision by comparing the early radiology experiences of Traditional and Foundation Trainees. Methods 344 radiology trainees were appointed through MMC in 2007/08. This cohort was surveyed online. Results Response rate was 174/344 (51%. Traditional Trainees made their career decision 2.6 years after graduation compared with 1.2 years for Foundation Trainees (57/167, 34%. Nearly half of responders (79/169, 47% experienced no formal radiology teaching as undergraduates. Most trainees regularly attended radiology meetings, spent time in a radiology department and/or performed radiology research. Many trainees received no career advice specific to radiology (69/163, 42% at any point prior to entering the specialty; this includes both formal and informal advice. Junior doctor experiences were more frequently cited as influencing career choice (98/164, 60%. An earlier career decision was associated with; undergraduate radiology projects (-0.72 years, p = 0.018, career advice (-0.63 years, p = 0.009 and regular attendance at radiology meetings (-0.65 years, p = 0.014. Conclusion Early experience of radiology enables trainees to make an earlier career decision, however current radiology trainees were not always afforded relevant experiences prior to entering training. Radiologists need to be more proactive in encouraging the next generation of trainees.

Despite increasing the integration of radiologic imaging teaching in anatomy dissection courses, studies on learning outcome of these interventions are rare or have certain shortcomings in study design. In this study, students were randomly allocated to an intervention group (n=53) receiving five weekly CT-courses of 30min duration during a 6-week gross anatomy course. Students in the control group (n=329) received no additional teaching. Total teaching time did not differ among groups. All students were asked to participate in a pre- and post-course self-assessment (comparative self-assessment; CSA) of learning objectives related to anatomical spatial relationships and a post-course formative assessment on radiologic anatomy. Items of both assessments were matched. Moreover, students of the intervention group were asked to evaluate the CT-courses. Most participants of the intervention group classified the CT-courses as "good" or "very good". Nevertheless, results of the CSA and formative assessment did not differ among study and control groups. These findings indicate that the teaching intervention (CT-courses) did not have an impact on recognition of anatomical structures in radiological images beyond the knowledge acquired in the anatomical dissection course. As a consequence, interventions integrating radiology imaging into dissection courses should be based on psychological considerations of how to best foster student learning. Learning outcome has to be monitored, as results of evaluation surveys can be misleading. Further research on curricular concepts is needed considering both short- and long-term effects.

Murphy, Kieran J; Elias, Gavin; Jaffer, Hussein; Mandani, Rashesh

2013-07-01

To investigate the nature of inventiveness among members of the Society of Interventional Radiology (SIR) and learn what influenced the inventors and assisted their creativity. The membership directory of the SIR was cross-referenced with filings at the United States Patent and Trademark Organization (USPTO) and the Patent Cooperation Treaty (PCT). The inventors were queried with an online survey to illuminate their institutions of training and practice as well as enabling or inhibiting factors to their inventiveness. Responses were analyzed through the construction of social network maps and thematic and graphical analysis. It was found that 457 members of the SIR held 2,492 patents or patent filings. After 1986, there was a marked and sustained increase in patent filings. The online survey was completed by 73 inventors holding 470 patents and patent filings. The social network maps show the key role of large academic interventional radiology departments and individual inventors in the formation of interconnectivity among inventors and the creation of the intellectual property (IP). Key inhibitors of the inventive process include lack of mentorship, of industry contacts, and of legal advice. Key enablers include mentorship, motivation, and industry contacts. Creativity and inventiveness in SIR members stem from institutions that are hubs of innovation and networks of key innovators; inventors are facilitated by personal motivation, mentorship, and strong industry contacts.

US Army Radiological Bioassay and Dosimetry: The RBD software package

International Nuclear Information System (INIS)

Eckerman, K.F.; Ward, R.C.; Maddox, L.B.

1993-01-01

The RBD (Radiological Bioassay and Dosimetry) software package was developed for the U. S. Army Material Command, Arlington, Virginia, to demonstrate compliance with the radiation protection guidance 10 CFR Part 20 (ref. 1). Designed to be run interactively on an IBM-compatible personal computer, RBD consists of a data base module to manage bioassay data and a computational module that incorporates algorithms for estimating radionuclide intake from either acute or chronic exposures based on measurement of the worker's rate of excretion of the radionuclide or the retained activity in the body. In estimating the intake,RBD uses a separate file for each radionuclide containing parametric representations of the retention and excretion functions. These files also contain dose-per-unit-intake coefficients used to compute the committed dose equivalent. For a given nuclide, if measurements exist for more than one type of assay, an auxiliary module, REPORT, estimates the intake by applying weights assigned in the nuclide file for each assay. Bioassay data and computed results (estimates of intake and committed dose equivalent) are stored in separate data bases, and the bioassay measurements used to compute a given result can be identified. The REPORT module creates a file containing committed effective dose equivalent for each individual that can be combined with the individual's external exposure

Mujika, Katrin Muradas; Méndez, Juan Antonio Juanes; de Miguel, Andrés Framiñan

2018-01-15

Currently, there are sophisticated applications that make it possible to visualize medical images and even to manipulate them. These software applications are of great interest, both from a teaching and a radiological perspective. In addition, some of these applications are known as Free Open Source Software because they are free and the source code is freely available, and therefore it can be easily obtained even on personal computers. Two examples of free open source software are Osirix Lite® and 3D Slicer®. However, this last group of free applications have limitations in its use. For the radiological field, manipulating and post-processing images is increasingly important. Consequently, sophisticated computing tools that combine software and hardware to process medical images are needed. In radiology, graphic workstations allow their users to process, review, analyse, communicate and exchange multidimensional digital images acquired with different image-capturing radiological devices. These radiological devices are basically CT (Computerised Tomography), MRI (Magnetic Resonance Imaging), PET (Positron Emission Tomography), etc. Nevertheless, the programs included in these workstations have a high cost which always depends on the software provider and is always subject to its norms and requirements. With this study, we aim to present the advantages and disadvantages of these radiological image visualization systems in the advanced management of radiological studies. We will compare the features of the VITREA2® and AW VolumeShare 5® radiology workstation with free open source software applications like OsiriX® and 3D Slicer®, with examples from specific studies.

Review of teaching methods and critical thinking skills.

Kowalczyk, Nina

2011-01-01

Critical information is needed to inform radiation science educators regarding successful critical thinking educational strategies. From an evidence-based research perspective, systematic reviews are identified as the most current and highest level of evidence. Analysis at this high level is crucial in analyzing those teaching methods most appropriate to the development of critical thinking skills. To conduct a systematic literature review to identify teaching methods that demonstrate a positive effect on the development of students' critical thinking skills and to identify how these teaching strategies can best translate to radiologic science educational programs. A comprehensive literature search was conducted resulting in an assessment of 59 full reports. Nineteen of the 59 reports met inclusion criteria and were reviewed based on the level of evidence presented. Inclusion criteria included studies conducted in the past 10 years on sample sizes of 20 or more individuals demonstrating use of specific teaching interventions for 5 to 36 months in postsecondary health-related educational programs. The majority of the research focused on problem-based learning (PBL) requiring standardized small-group activities. Six of the 19 studies focused on PBL and demonstrated significant differences in student critical thinking scores. PBL, as described in the nursing literature, is an effective teaching method that should be used in radiation science education. ©2011 by the American Society of Radiologic Technologists.

Developing standard transmission system for radiology reporting including key images

International Nuclear Information System (INIS)

Kim, Seon Chil

2007-01-01

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

E-learning, an abbreviation of electronic learning, indicates the provision of education and training on the Internet or the World Wide Web. The impact of networks and the Internet on radiology is undoubtedly important, as it is for medicine as a whole. The Internet offers numerous advantages compared with other mass media: it provides access to a large amount of information previously known only to individual specialists; it is flexible, permitting the use of images or video; and it allows linking to Web sites on a specific subject, thus contributing to further expand knowledge. Our purpose is to illustrate the regulatory aspects (including Internet copyright laws), current radiological applications and future prospects of e-learning. Our experience with the installation of an e-learning platform is also presented. We performed a PubMed search on the published literature (without time limits) dealing with e-learning tools and applications in the health sector with specific reference to radiology. The search included all study types in the English language with the following key words: e-learning, education, teaching, online exam, radiology and radiologists. The Fiaso study was referred to for the regulatory aspects of e-learning. The application of e-learning to radiology requires the development of a model that involves selecting and creating e-learning platforms, creating and technologically adapting multimedia teaching modules, creating and managing a unified catalogue of teaching modules, planning training actions, defining training pathways and Continuing Education in Medicine (CME) credits, identifying levels of teaching and technological complexity of support tools, sharing an organisational and methodological model, training the trainers, operators' participation and relational devices, providing training, monitoring progress of the activities, and measuring the effectiveness of training.

Willatt, J.M.G.; Mason, A.C.

2006-01-01

The purpose of our study was to compare various aspects of radiology training schemes in ten countries. A questionnaire was sent to senior residents in the UK, USA, Canada, Australia, New Zealand, Italy, Egypt, India, Malaysia and Greece. The questions concerned length of training, required pre-training experience, the organization of the training scheme, teaching, resources, stages at which residents can independently perform and report examinations, fellowships, and progression to jobs. A wide variety of training, ranging from highly scheduled programs with detailed aims and objectives, to self-learning occurs across the world. Examinations and assessments are also variable. There are lessons to be learned from varying practices; more exchanges of ideas should be encouraged. In view of the ''internationalization'' of radiology services and the variation in training styles an international qualification for quality assurance purposes may be desirable. (orig.)

Croft, J.R.; Hudson, A.P.

1981-01-01

Courses in Radiological Protection have been organised at Leeds by the NRPB since its formation, and prior to that by the Leeds Centre of the Radiological Protection Service. From the outset it seemed essential that such courses should contain a practical element, and accordingly a number of exercises were drawn up. Since that time further exercises have been added, often in response to a specific requirement from a customer or group of customers. Most of the exercises have involved the design and construction of 'one-off' items of equipment, a number of which can be considered to represent interesting approaches towards radiological protection teaching. The construction of a 'second generation' of hardware has focused attention on the objectives and design features of the exercises, which in turn has prompted a desire to publish a series of short papers describing the pool of exercises that is currently available for inclusion in the various courses run by the NRPB Centres. The first of these papers puts the series into context and provides a background to the descriptions of specific exercises. (author)

Among methods of "blended learning" (ie, combining online modules with in-class instruction), the "flipped classroom" involves student preclass review of material while reserving class time for interactive knowledge application. We integrated blended learning methodology in a "flipped" introductory clerkship in radiology, and assessed the impact of this approach on the student educational experience (performance and perception). In preparation for the "flipped clerkship," radiology faculty and residents created e-learning modules that were uploaded to an open-source website. The clerkship's 101 rising third-year medical students were exposed to different teaching methods during the course, such as blended learning, traditional lecture learning, and independent learning. Students completed precourse and postcourse knowledge assessments and surveys. Student knowledge improved overall as a result of taking the course. Blended learning achieved greater pretest to post-test improvement of high statistical significance (P value, .0060) compared to lecture learning alone. Blended learning also achieved greater pretest to post-test improvement of borderline statistical significance (P value, .0855) in comparison to independent learning alone. The difference in effectiveness of independent learning versus lecture learning was not statistically significant (P value, .2730). Student perceptions of the online modules used in blended learning portions of the course were very positive. They specifically enjoyed the self-paced interactivity and the ability to return to the modules in the future. Blended learning can be successfully applied to the introductory clerkship in radiology. This teaching method offers educators an innovative and efficient approach to medical student education in radiology. Copyright © 2015 AUR. Published by Elsevier Inc. All rights reserved.

There is an increasing trend of outsourcing public departments. Teaching hospitals also outsourced some of their departments to private sectors. The aim of this study was to investigate and compare the educational status of students in public and outsourced departments of teaching hospitals affiliated to Iran University of Medical Sciences. This study was conducted in six teaching hospitals of Iran University of Medical Sciences, which had public and outsourced teaching departments in 2015. One hundred fifty students from the departments of radiology, physiotherapy and laboratory participated in this study and their perceptions about their educational status were assessed. A valid and reliable questionnaire was used; participation in the study was voluntary. Descriptive statistics such as mean (SD), t-test and Kolmogorov-Smirnov were used. No difference was detected between the educational status of students in public and outsourced departments of radiology, physiotherapy and laboratory (p>0.05). Based on the students' perception, the private sectors could maintain the educational level of the teaching departments similar to the public departments. It is recommended to involve all the stakeholders such as hospital administrators, academic staff and students in the decision- making process when changes in teaching environments are being considered.

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

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.

Problems of methodology, organization, and evaluation confronting the radiology departments of the university hospitals affiliated with the University of Montreal, the medical students, and the University itself in connection with an elective internship in radiology offered in the fifth year of medicine, resulted in the formation of a committee to reorganize the course of study. In this concise article the authors describe this and other measures taken by the University to solve these problems. The committees' main purpose was to restructure the internship which was made compulsory so that future physicians would be prepared to draw on the resources of diagnostic radiology and nuclear medicine. To this end, the committee formulated the objectives, content, evaluation system, and pedagogical methods to be used in those courses. The 25 self-teaching modules, together with the observation and practical interpretation of radiology sessions, proved highly useful in solving the initial problems, and were of particular interest to the students.

The Radiology Operations Management computer system at the Hospital of the University of Pennsylvania is discussed. The scheduling and file room modules are based on the system at Massachusetts General Hospital. Patient delays are indicated by the patient tracking module. A reporting module allows CRT/keyboard entry by transcriptionists, entry of standard reports by radiologists using bar code labels, and entry by radiologists using a specialty designed diagnostic reporting terminal. Time-flow analyses demonstrate a significant improvement in scheduling, patient waiting, retrieval of radiographs, and report delivery. Recovery of previously lost billing contributes to the proved cost effectiveness of this system.

This report documents the nuclear decay data files used by the Dosimetry Research Group at Oak Ridge National Laboratory and the utility DEXRAX which provides access to the files. The files are accessed, by nuclide, to extract information on the intensities and energies of the radiations associated with spontaneous nuclear transformation of the radionuclides. In addition, beta spectral data are available for all beta-emitting nuclides. Two collections of nuclear decay data are discussed. The larger collection contains data for 838 radionuclides, which includes the 825 radionuclides assembled during the preparation of Publications 30 and 38 of the International Commission on Radiological Protection (ICRP) and 13 additional nuclides evaluated in preparing a monograph for the Medical Internal Radiation Dose (MIRD) Committee of the Society of Nuclear Medicine. The second collection is composed of data from the MIRD monograph and contains information for 242 radionuclides. Abridged tabulations of these data have been published by the ICRP in Publication 38 and by the Society of Nuclear Medicine in a monograph entitled ''MIRD: Radionuclide Data and Decay Schemes.'' The beta spectral data reported here have not been published by either organization. Electronic copies of the files and the utility, along with this report, are available from the Radiation Shielding Information Center at Oak Ridge National Laboratory

Film-based radiographs are still being used to teach in a conference format, which presents several viewing challenges amongst other problems. In the age of cloud computing, which enables the use of online server storage space, this information could be used more effectively if it were digitized. However, digitizing film-based radiographs and making them available for use in the cloud is not as easy as it seems. In order to address the issue of digitizing the film-based radiograph libraries in our radiology department, we looked at several options. The option that we chose was a consumer-grade scanner, and this decision was based on price, resolution, shades of gray, built-in transparency function, and its physical attributes. Our goal was to digitize the film-based radiograph teaching files so they could be stored in a digital file locker such as Google Picassa for organization and quick access later. These files would constantly be updated in a Google document by residents, and this document would be called the "Living Document" based on its continuous expandability. This method would allow even the smallest radiology department to benefit from the use of modern technology to gain access to valuable information stored in film-based radiographs and give every resident the opportunity to benefit from it.

The purpose of this study was to investigate the consistency of working length control between hand instrumentation in comparison to engine driven Mtwo nickel-titanium rotary files. Forty extracted maxillary molars were selected and divided onto two parallel groups. The working lengths of the mesiobuccal root canals were estimated. The teeth were fixed in a phantom head. The root canal preparation was carried out group 1 (n=20) with hand K-files, (VDW, Munich, Germany) and group 2 (n=20) with Mtwo instruments (VDW, Munich, Germany). Vestibulo-oral and mesio-distal directional x-ray images were taken before the preparation with #10 K-file, inserted into the mesiobuccal root canal to the working length, and after preparation with #25, #30 and #40 files. Working lenght changes were detected with measurements between the radiological apex and the instrument tips. In the Mtwo group a difference in the working competency (protary files. Mtwo NiTi rotary file did therefore proved to be more accurate in comparison to the conventional hand instrumentation.

Background: There is an increasing trend of outsourcing public departments. Teaching hospitals also outsourced some of their departments to private sectors. The aim of this study was to investigate and compare the educational status of students in public and outsourced departments of teaching hospitals affiliated to Iran University of Medical Sciences. Methods: This study was conducted in six teaching hospitals of Iran University of Medical Sciences, which had public and outsourced teaching departments in 2015. One hundred fifty students from the departments of radiology, physiotherapy and laboratory participated in this study and their perceptions about their educational status were assessed. A valid and reliable questionnaire was used; participation in the study was voluntary. Descriptive statistics such as mean (SD), t-test and Kolmogorov-Smirnov were used. Results: No difference was detected between the educational status of students in public and outsourced departments of radiology, physiotherapy and laboratory (p>0.05). Conclusion: Based on the students’ perception, the private sectors could maintain the educational level of the teaching departments similar to the public departments. It is recommended to involve all the stakeholders such as hospital administrators, academic staff and students in the decision- making process when changes in teaching environments are being considered.

In this work, the general purpose Monte Carlo N-particle radiation transport computer code (MCNP-4C) was used for the simulation of X-ray spectra in diagnostic radiology. The electron's path in the target was followed until its energy was reduced to 10 keV. A user-friendly interface named 'diagnostic X-ray spectra by Monte Carlo simulation (DXRaySMCS)' was developed to facilitate the application of MCNP-4C code for diagnostic radiology spectrum prediction. The program provides a user-friendly interface for: (i) modifying the MCNP input file, (ii) launching the MCNP program to simulate electron and photon transport and (iii) processing the MCNP output file to yield a summary of the results (relative photon number per energy bin). In this article, the development and characteristics of DXRaySMCS are outlined. As part of the validation process, output spectra for 46 diagnostic radiology system settings produced by DXRaySMCS were compared with the corresponding IPEM78. Generally, there is a good agreement between the two sets of spectra. No statistically significant differences have been observed between IPEM78 reported spectra and the simulated spectra generated in this study.

Radiology teachers are well trained in their specialty; however, when working in academic institutions, faculty development and promotion through the education pathway tends to be based on their teaching knowledge and skills. The aim of this study is to assess psychometric properties of the Medicina Universidad Católica-Radiology 32 items (MEDUC-RX32), an instrument designed to evaluate the performance of postgraduate radiology teachers and to identify the best teachers. Mixed methodology was used, including qualitative and quantitative phases. The psychometric properties of the MEDUC-RX32 survey were performed by factor analysis (validity), Cronbach alpha coefficient, and G coefficient (reliability). The residents assessed their teachers and simultaneously voted for the "best teacher," which was used as a gold standard for the receiver operating characteristic curves construction comparing their votes with the global score. A total of 28 residents answered 164 surveys. The global score was 6.23 ± 0.8 (scale from 1 to 7). The factor analysis showed six domains of the resident's perception: (1) tutorial teaching, feedback, and independent learning; (2) communication and teamwork; (3) learning objectives; (4) respectful behavior; (5) radiological report; and (6) teaching and care support. The tutor's strengths were related with respectful behavior and teamwork. The instrument is highly reliable with a Cronbach alpha of 0.937 and a G coefficient of 0.831 (with a minimum of 8 residents). The MEDUC-RX32 instrument has a sensitivity of 91.7% and specificity of 83.3% to identify tutors as best teachers with at least one vote with an area under the receiver operating characteristic curve of 0.931 with a cutoff of 5.94. The MEDC-RX32 instrument is a multidimensional, valid, and highly reliable method to evaluate radiology teachers, identifying teachers with excellence in tutorial teaching in a postgraduate radiology program.

Three computerized multimedia programs on large and small animal veterinary orthopedic radiology were developed and implemented for the radiology curriculum as an alternative to traditional film-based laboratory learning. Programs utilized ''hot words'' (colored text words that displayed an overlaid image label that highlighted lesions) and interactive quizzes which responded appropriately to selected answers. ''Hot words'' helped students develop confidence in accurate lesion detection and the interactive quizzes transformed learning from a passive to an active process. Multiple examples were provided for reinforcement and concepts were incorporated from other clinical disciplines for curriculum integration. Programs were written using a presentation software program, Toolbook for DOS based platform, and contained radiographic images made by laser-scanning digitization. Multiple students could simultaneously access the programs through a network server. These pilot programs were implemented successfully and computerized multimedia presentation proved to be well suited to teaching radiology. Development of the programs required attention to a number of hardware, software, time and cost factors

Full Text Available Abstract Background The development of multidisciplinary team meetings (MDTMs for radiology and pathology is a burgeoning area that increasingly impacts on work processes in both of these departments. The aim of this study was to examine work processes and quantify the time demands on radiologists and pathologists associated with MDTM practices at a large teaching hospital. The observations reported in this paper reflect a general trend affecting hospitals and our conclusions will have relevance for others implementing clinical practice guidelines. Methods For one month, all work related to clinical meetings between pathology and radiology with clinical staff was documented and later analysed. Results The number of meetings to which pathology and radiology contribute at a large university teaching hospital, ranges from two to eight per day, excluding grand rounds, and amounts to approximately 50 meetings per month for each department. For one month, over 300 h were spent by pathologists and radiologists on 81 meetings, where almost 1000 patients were discussed. For each meeting hour, there were, on average, 2.4 pathology hours and 2 radiology hours spent in preparation. Two to three meetings per week are conducted over a teleconferencing link. Average meeting time is 1 h. Preparation time per meeting ranges from 0.3 to 6 h for pathology, and 0.5 to 4 for radiology. The review process in preparation for meetings improves internal quality standards. Materials produced externally (for example imaging can amount to almost 50% of the material to be reviewed on a single patient. The number of meetings per month has increased by 50% over the past two years. Further increase is expected in both the numbers and duration of meetings when scheduling issues are resolved. A changing trend in the management of referred patients with the development of MDTMs and the introduction of teleconferencing was noted. Conclusion Difficulties are being experienced by

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

An accurate knowledge of the output energy spectra of an x-ray tube is essential in many areas of radiological studies. It forms the basis of almost all image quality simulations and enable system designers to predict patient dose more accurately. Many radiological physics problems that can be solved by Monte Carlo simulation methods require an x-ray spectra as input data. Computer simulation of x-ray spectra is one of the most important tools for investigation of patient dose and image quality in diagnostic radiology systems. In this work the general purpose Monte Carlo N-particle radiation transport computer code (MCNP-4C) was used for the simulation of x-ray spectra in diagnostic radiology, Electron's path in the target was followed until it's energy was reduced to 10 keV. A user friendly interface named 'Diagnostic X-ray Spectra by Monte Carlo Simulation (DXRaySMCS)' was developed to facilitate the application of MCNP-4C code for diagnostic radiology spectrum prediction.

In this article the development and characteristics of DXRaySMCS are outlined. As part of the validation process, out put spectra for 46 diagnostic radiology system settings produced by DXRaySMCS were compared with the corresponding IPEM78. Generally, there is a good agreement between the two sets of spectra.

page of the Web site provided the schedule, faculty names, attendance and grading policies, course overview, and links to individual tutorials. The pages for individual tutorials included educational objectives, glossary of radiology terminology relevant to the subject, lecture slides and handouts, and teaching cases. All students had laptop computers and access to the academic network, but did not use them during the actual tutorial sessions. Implementation of the radiology clerkship required extensive negotiation with directors of other clerkships so that students could be released from their other responsibilities in order to attend the radiology tutorials. The radiology clerkship format has proven to be complex in its administration, with faculty and students on different schedules commuting to the radiology lecture hall from various locations. Extensive use of e-mail and communication via the Web site have been instrumental in reminding faculty and students of upcoming sessions. Preliminary evaluations have indicated that students liked the radiology sessions and learned a great deal, but disliked the scheduling and the lack of continuity. An evaluation of the curriculum and its components is ongoing.

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

Exposure Computational Models (ECMs) are utilities that simulate situations in which occurs irradiation in a given environment. An ECM is composed primarily by an anthropomorphic model (phantom), and a Monte Carlo code (MC). This paper presents a tutorial of the software Espectro de Raios-X (ERX). This software performs reading and numerical and graphical analysis of text files containing diagnostic X-ray spectra for use in algorithms of radioactive sources in the ECMs of a Grupo de Dosimetria Numerica. The ERX allows the user to select one among several X-ray spectrums in the energy range Diagnostic radiology X-Ray most commonly used in radiology clinics. In the current version of the ERX there are two types of input files: the contained in mspectra.dat file and the resulting of MC simulations in Geant4. The software allows the construction of charts of the Probability Density Function (PDF) and Cumulative Distribution Function (CDF) of a selected spectrum as well as the table with the values of these functions and the spectrum. In addition, the ERX allows the user to make comparative analysis between the PDF graphics of the two catalogs of spectra available, besides being can perform dosimetric evaluations with the selected spectrum. A software of this kind is an important computational tool for researchers in numerical dosimetry because of the diversity of Diagnostic radiology X-Ray machines, which implies in a mass of input data highly diverse. And because of this, the ERX provides independence to the group related to the data origin that is contained in the catalogs created, not being necessary to resort to others. (author)

To develop a valid and reliable radiology faculty appraisal instrument based on scientific methods. Fifteen radiology residents participated in critical incident interviewing. During a 1-hour interview, a resident was asked to describe five incidents each of effective and ineffective faculty behavior. Two investigators independently listened to the tape-recorded interviews, and two different investigators sorted the incidents into broad categories. A faculty appraisal instrument was developed by listing similar incidents under broad categories. A five-point rating scale was applied to each item. Content validity was assessed by resident and faculty critique of the appraisal instrument. A total of 168 incidents of faculty behavior were generated. The frequency with which similar incidents were reported was recorded. The most common behaviors reported were related to staff expertise and teaching. Interjudge reliability was good, as determined by computing K indices of agreement (overall K = 0.59). There was good agreement regarding instrument content validity among residents but not among faculty. Residents supported the use of the new appraisal instrument, but further tests of validity and reliability and faculty acceptance of the instrument will determine its usefulness as a tool for monitoring faculty teaching performance and making decisions regarding faculty promotion.

Educational research suggests that cognitive processing in diagnostic radiology requires a solid foundation in the basic sciences and knowledge of the radiological changes associated with disease. Although it is generally assumed that dental students must acquire both sets of knowledge, little is known about the most effective way to teach them. Currently, the basic and clinical sciences are taught separately. This study was conducted to compare the diagnostic accuracy of students when taught basic sciences segregated or integrated with clinical features. Predoctoral dental students (n=51) were taught four confusable intrabony abnormalities using basic science descriptions integrated with the radiographic features or taught segregated from the radiographic features. The students were tested with diagnostic images, and memory tests were performed immediately after learning and one week later. On immediate and delayed testing, participants in the integrated basic science group outperformed those from the segregated group. A main effect of learning condition was found to be significant (pbasic sciences integrated with clinical features produces higher diagnostic accuracy in novices than teaching basic sciences segregated from clinical features.

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)

Audience response techniques for 21st century radiology education.

Richardson, Michael L

2014-07-01

Audience response system (ARS) provides an excellent tool for improving interactive learning in radiology residents. However, it is not the technology but the pedagogy that matters the most. It is long past time to upgrade our ARS teaching techniques to match our ARS technology. In this article, several problems with current usage of ARS are discussed and several prescriptions for improving this are presented. Simplifying the ease of use of ARS will get this useful technology into more hands. Using ARS in a bidirectional manner will give us an even better idea of how and what our students are learning. Asking questions on the fly will obviate the usual tedium of multiple-choice questions and allow us to quiz our students in a much more natural manner. It is time to move on to more innovative ARS techniques that are well adapted to radiology and its different styles of learning. Copyright © 2014 AUR. Published by Elsevier Inc. All rights reserved.

Incorporating newer teaching aids over traditional one in Anatomy has been challenging both for the teachers and the learners. Different educational strategies are being used for teaching of Anatomy. To elicit the perception and attitude toward teaching approaches in the Anatomy curriculum among first year medical students. A cross-sectional, descriptive study was undertaken with the help of predesigned, pre-tested questionnaire to elicit knowledge in four domains of classroom teaching which were: a) gross anatomical structure; b) organ identification; c) topography; and d) radiological anatomy and self-assessment of acquired skills in respective fields among 114 first year students. A total of 57% of students opined good in gross structure of anatomy. A 60.5% of students preferred chalk and board method and 33.3% with LCD projector. Regarding acquiring knowledge, 72.8% of medical students gathered knowledge in gross anatomical structure domain whereas 58.8% in radiological anatomy. The overall mean score of attitude of the students regarding incorporating newer techniques in Anatomy teaching is 14.17±2.26. The perception of Anatomy teaching and attitude among medicos have been studied and opinion from them had thrown light for incorporation of newer techniques in their teaching curriculum.

Lo, Shih-Chung B.; Shen, Ellen L.; Mun, Seong K.

1990-07-01

A new decomposition method using image splitting and gray-level remapping has been proposed for image compression, particularly for images with high contrast resolution. The effects of this method are especially evident in our radiological image compression study. In our experiments, we tested the impact of this decomposition method on image compression by employing it with two coding techniques on a set of clinically used CT images and several laser film digitized chest radiographs. One of the compression techniques used was full-frame bit-allocation in the discrete cosine transform domain, which has been proven to be an effective technique for radiological image compression. The other compression technique used was vector quantization with pruned tree-structured encoding, which through recent research has also been found to produce a low mean-square-error and a high compression ratio. The parameters we used in this study were mean-square-error and the bit rate required for the compressed file. In addition to these parameters, the difference between the original and reconstructed images will be presented so that the specific artifacts generated by both techniques can be discerned by visual perception.

Radiology expertise is dependent on the use of efficient search strategies. The aim of this study is to investigate the effect of teaching search strategies on trainee's accuracy in detecting lung nodules at computed tomography. Two search strategies, "scanning" and "drilling," were tested with a randomized crossover design. Nineteen junior radiology residents were randomized into two groups. Both groups first completed a baseline lung nodule detection test allowing a free search strategy, followed by a test after scanning instruction and drilling instruction or vice versa. True positive (TP) and false positive (FP) scores and scroll behavior were registered. A mixed-design analysis of variance was applied to compare the three search conditions. Search strategy instruction had a significant effect on scroll behavior, F(1.3) = 54.2, P search (M = 15.3, SD = 4.6), t(18) = 4.44, P search. FP scores for drilling (M = 7.3, SD = 5.6) were significantly lower than for free search (M = 12.5, SD = 7.8), t(18) = 4.86, P < 0.001. Teaching a drilling strategy is preferable to teaching a scanning strategy for finding lung nodules. Copyright © 2017 The Association of University Radiologists. Published by Elsevier Inc.

Renewal of radiological equipment.

Science.gov (United States)

2014-10-01

In this century, medical imaging is at the heart of medical practice. Besides providing fast and accurate diagnosis, advances in radiology equipment offer new and previously non-existing options for treatment guidance with quite low morbidity, resulting in the improvement of health outcomes and quality of life for the patients. Although rapid technological development created new medical imaging modalities and methods, the same progress speed resulted in accelerated technical and functional obsolescence of the same medical imaging equipment, consequently creating a need for renewal. Older equipment has a high risk of failures and breakdowns, which might cause delays in diagnosis and treatment of the patient, and safety problems both for the patient and the medical staff. The European Society of Radiology is promoting the use of up-to-date equipment, especially in the context of the EuroSafe Imaging Campaign, as the use of up-to-date equipment will improve quality and safety in medical imaging. Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or renewal. This plan should look forward a minimum of 5 years, with annual updates. Teaching points • Radiological equipment has a definite life cycle span, resulting in unavoidable breakdown and decrease or loss of image quality which renders equipment useless after a certain time period.• Equipment older than 10 years is no longer state-of-the art equipment and replacement is essential. Operating costs of older equipment will be high when compared with new equipment, and sometimes maintenance will be impossible if no spare parts are available.• Older equipment has a high risk of failure and breakdown, causing delays in diagnosis and treatment of the patient and safety problems both for the patient and the medical staff.• Every healthcare institution or authority should have a plan for medical imaging equipment upgrade or replacement.

Spanish Radiology in the second half of the XX Century: A view from inside

Bonmati, Jose

2008-01-01

Radiology was born in 1896 with the immediate recognition of the diagnostic value of X-rays in medicine and progressed throughout the XX Century with the increasing knowledge of its properties and clinical applications. By mid-century Radiology was a respected clinical specialty in advanced countries, the radiological report was a requirement in hospital practice and radiologists' opinions requested in scientific meetings. In the last decades of the century has had a spectacular expansion with the emergence of new imaging modalities and revolutionary technologies that have transformed the specialty worldwide. In Spain Radiology lagged behind needs and demand in 1950. Radiological practice was unregulated and performance of X-ray exams by non-radiologists was common. Teaching of Radiology was non-existent in Medical Schools or postgraduation. The diagnostic value of the specialty was unrecognized by physicians and the role of radiologists ignored. Most hospital radiology services were poorly equipped and functionally inadequate. The shadow of the Civil War (1936-39) was conditioning Radiology in the country. The point of inflexion in the development of Radiology in Spain was the inclusion of film reading sessions in the 1965 academic program of the Society of Radiology. It was in the presentation of cases at these conferences that Clinical Radiology found the finest demonstration ground and as a result was immediately adopted by radiologists and progressively applied in scientific meetings, clinical practices and training programs. Its influence was important in reforming hospital practice, legislation on specialization and education, as well as in national health care plans. At the end of the century radiology in Spain was at a par with the standards of other western nations. The author was a witness of the evolution of Radiology during his 50 years of professional life. This article does not pretend to be exhaustive in names or contributions. It is an overview of

Panoramic radiography is the most frequent extraoral examination in dentistry. This technique allows the visualization of adjacent maxillomandibular and anatomical structures. Although digital imaging systems are already the great majority of dental radiology services, there is still a shortage of works evaluating the quality of this type of image. The objective of this study was to identify the rejection index of digital panoramic radiographs of a dental radiology service of a university in Brazil, pointing out the main reasons. A survey was performed on the image files and, randomly selected, 2306 images, 10% of the examinations performed in the period between 2013 to 2015. The results indicated a total rejection rate of 5.1% over the three years, totaling 117 radiographs. The main reasons for rejection were: the patient's head tilted backwards in 2013 and the lack of tongue contact with the palate, for the years 2014 and 2015. The main reasons for repetition of exams are related to the positioning in the execution of the technique radiological factors, which may be related to the lack of professional training. Patient collaboration during the examination and professional-to-patient communication failures may result in poor diagnostic quality exams

Connecting university science experiences to middle school science teaching

Johnson, Gordon; Laughran, Laura; Tamppari, Ray; Thomas, Perry

1991-06-01

Science teachers naturally rely on their university science experiences as a foundation for teaching middle school science. This foundation consists of knowledge far too complex for the middle level students to comprehend. In order for middle school science teachers to utilize their university science training they must search for ways to adapt their college experiences into appropriate middle school learning experience. The criteria set forth above provide broad-based guidelines for translating university science laboratory experiences into middle school activities. These guidelines are used by preservice teachers in our project as they identify, test, and organize a resource file of hands-on inquiry activities for use in their first year classrooms. It is anticipated that this file will provide a basis for future curriculum development as the teacher becomes more comfortable and more experienced in teaching hands-on science. The presentation of these guidelines is not meant to preclude any other criteria or considerations which a teacher or science department deems important. This is merely one example of how teachers may proceed to utilize their advanced science training as a basis for teaching middle school science.

To assess resources available to junior faculty in US academic radiology departments for research mentorship and funding opportunities and to determine if certain resources are more common in successful programs. An anonymous survey covering scientific environment and research mentorship and was sent to vice-chairs of research of radiology departments. Results were evaluated to identify practices of research programs with respect to mentorship, resources, and opportunities. Academy of Radiology Research's 2012 National Institutes of Health (NIH) grants and awards list was used to determine if environment and practices correlate with funding. There was a 51% response rate. A greater fraction of clinical faculty gets promoted from assistant to associate professor than research faculty. Research faculty overall submits more funding applications. Most programs support start-up costs and K-awards. Over half of the departments have a vice-chair for faculty development, and most have formal mentorship programs. Faculty members are expected to teach, engage in service, publish, and apply for and get research funding within 3 years of hire. Top-tier programs as judged by NIH awards have a combination of MDs who devote >50% effort to research and PhD faculty. Key factors holding back both clinical and research junior faculty development were motivation, resources, and time, although programs reported high availability of resources and support at the department level. Better marketing of resources for junior faculty, effort devoted to mentoring clinical faculty in research, and explicit milestones/expectations for achievement could enhance junior faculty success, promote interest in the clinician–scientist career path for radiologists, and lead to greater research success.

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.

Highlights: • Medical students tend to overstate their knowledge of radiation protection (RP). • Overall RP knowledge of young doctors and students is suboptimal. • RP teaching to undergraduates and postgraduates needs to be substantially improved. - Abstract: Purpose: To evaluate the awareness of radiation protection issues and the knowledge of dose levels of imaging procedures among medical students, radiology residents, and radiography students at an academic hospital. Material and methods: A total of 159 young doctors and students (including 60 radiology residents, 56 medical students, and 43 radiography students) were issued a questionnaire consisting of 16 multiple choice questions divided into three separated sections (i.e., demographic data, awareness about radiation protection issues, and knowledge about radiation dose levels of common radiological examinations). Results: Medical students claimed to have at least a good knowledge of radiation protection issues more frequently than radiology residents and radiography students (94.4% vs 55% and 35.7%, respectively; P < 0.05), with no cases of perceived excellent knowledge among radiography students. However, the actual knowledge of essential radiation protection topics such as regulations, patient and tissue susceptibility to radiation damage, professional radiation risk and dose optimisation, as well as of radiation doses delivered by common radiological procedures was significantly worse among medical students than radiology residents and radiography students (P < 0.05). Those latter significantly outperformed radiology residents as to knowledge of radiation protection issues (P < 0.01). Overall, less than 50% of survey respondents correctly answered all questions of the survey. Conclusions: Radiology residents, radiography students and medical students have a limited awareness about radiation protection, with a specific gap of knowledge concerning real radiation doses of daily radiological

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.

Objectives: How do students experience and perceive the innovative undergraduate radiology curriculum at Ghent University, and what explains differences in student perception? Methods: A survey was presented to the 2008 cohort of students enrolled in the undergraduate medical curriculum at Ghent University. The survey focused on their experiences and perceptions in relation to the innovative undergraduate radiology teaching. Results and conclusion: The present research results point at a favorable perception of the innovative radiology curriculum components. The study points - both during pre-clinical and clinical years - at the appreciation for curriculum components that combine traditional curriculum components (ex-cathedra lessons with syllabus) with distance learning components such as E-learning and E-testing. In clinical years - as expected - students switch to the application of knowledge and skills and therefore heavily appreciate practice linked curriculum components.

The ninth version of the licensing regulation for medical doctors (Approbation Regulation (AR)) sets a benchmark in terms of practical experience, interdigitation of preclinical and clinical studies, interdisciplinary approach, economic efficiency, independence of students, added new teaching and learning modalities, and ongoing evaluation of the progress of the medical students. It is the aim to implement these major points of the AR in a model course for diagnostic radiology and radiation protection within the scope of the Virtual University of Bavaria and test them in practice. In cooperation with residents and board certified radiologists, students developed the virtual course "Web-Based Training (WBT) Radiology" in diagnostic radiology and radiation protection for students in the first clinical semester. A representative target group taken from the student body was asked about the options to get access to the World Wide Web (Internet), and the satisfaction concerning configuration and content of the newly developed program. A comparison was made between the results of the final examination taken by students who made use of the virtual course in addition to conventional lessons and taken by students who did not subscribe to the virtual course and exclusively relied on conventional lessons. In addition, a pilot study was conducted in the winter semester 2002/03, which compared students taking either the traditional lessons or the new virtual course on the Internet. The virtual course-model had test results with a positive trend. All targeted students had Internet access. Constructive criticism was immediately implemented and contributed to rapid optimization. The learning success of the additive or alternative virtual course was in no way less than the learning success achieved with the conventional course. The learning success as measure of quality in teaching and the acceptance by students and teachers justify the continuation of this course model and its

Determining the rate at which radiology must be digitalised has been a controversial issue for many years. Much radiological information is still obtained from the film-screen combination (X-rays) with all of its known inherent restrictions. The importance of imaging information in the healthcare process continues to increase for both radiologists and referring physicians, and the ongoing developments in information technology means that it is possible to integrate imaging information and electronic patient files. The healthcare process can only become more effective and efficient when the appropriate information is in the right place at the right time, something that conventional methods, using photos that need to be physically moved, can scarcely satisfy. There is also a desire for integration with information obtained from nuclear medicine, pathology and endoscopy, and eventually of all stand-alone data systems with relevance for the individually oriented hospital healthcare. The transition from a conventional to a digital process is complex; it is accompanied by the transition from a data-oriented to a process-oriented system. Many years have already been invested in the integration of information systems and the development of digital systems within radiology, the current performance of which is such that many hospitals are considering the digitalisation process or are already implementing parts of it.

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.

Williams, Stuart M.; Connelly, Daniel J.; Wadsworth, Susan; Wilson, David

2000-01-01

AIM: To assess the impact and cost effectiveness of a system of radiological review of accident and emergency (A and E) plain films. MATERIALS AND METHODS: Review documentation was studied retrospectively over a 1-year period. Six hundred and eighty-four actual or suspected errors in the initial radiological interpretation by A and E staff were highlighted by radiologists in training. These selected 'red reports' were then further reviewed by a musculoskeletal radiologist and a more senior member of the A and E team. RESULTS: Three hundred and fifty-one missed or strongly suspected fractures were detected, with ankle, finger and elbow lesions predominating. Other errors included 11 missed chest radiograph abnormalities and 24 A and E false-positives. Radiologists in training tended to over-report abnormalities with an 18% false-positive rate when compared to the subsequent musculoskeletal radiology opinion. Following review, further action was taken by A and E staff in 286 (42.6%) of cases. No operative intervention was required in those patients with a delayed or missed A and E diagnosis. Consideration is given to the cost of providing this form of review and the impact of medico-legal factors. CONCLUSION: Compared with the large numbers of patients seen and radiographed in a busy A and E department, the number of radiological errors was small. There were even fewer changes in management. Despite this, concern over litigation, clinical governance and future work patterns in A and E make this form of review a useful means of risk reduction in a teaching hospital. Williams, S.M. (2000).

Simulation has been used as an educational and assessment tool in several fields, generally involving training of physical skills. To date, simulation has found limited application in teaching and assessment of skills related to image perception and interpretation. The goal of this pilot study was to evaluate the feasibility of simulation as a tool for teaching and assessment of skills related to perception of nodules on chest radiography. This study received an exemption from the institutional review board. Subjects consisted of nonradiology health care trainees. Subjects underwent training and assessment of pulmonary nodule identification skills on chest radiographs at simulated radiology workstations. Subject performance was quantified by changes in area under the localization receiver operating characteristic curve. At the conclusion of the study, all subjects were given a questionnaire with five questions comparing learning at a simulated workstation with training using conventional materials. Statistical significance for questionnaire responses was tested using the Wilcoxon signed rank test. Subjects demonstrated statistically significant improvement in nodule identification after training at a simulated radiology workstation (change in area under the curve, 0.1079; P = .015). Subjects indicated that training on simulated radiology workstations was preferable to conventional training methods for all questions; P values for all questions were less than .01. Simulation may be a useful tool for teaching and assessment of skills related to medical image perception and interpretation. Further study is needed to determine which skills and trainee populations may be most amenable to training and assessment using simulation. Copyright © 2015 American College of Radiology.

McGee, Kristen

2003-01-01

Child life programming is predominantly developed in inpatient areas throughout major pediatric hospitals. However, the trend toward outpatient services has increased the need for facilities to develop child life positions to assist in the teaching demands of patients and families coming in for routine hospital visits. Since radiology is often the first experience for families, but not the last, it is essential to involve them in a positive experience. Imaging facilities serving pediatric patients are currently developing or considering child life programs. A certified child life specialist (CCLS) is committed to developing programming that enhances the child's understanding and involvement in their medical experience. This paper provides an outline of the responsibilities and areas of expertise of the CCLS in a pediatric radiology department. The reviewed program is based on, but not limited, to fluoroscopy.

To provide radiology departmental promotional committees and vice chairs of education with a more global perspective on the types of academic activity valued by institutions to aid in their faculty mentoring and standardizing of the Clinician-Educator (ClinEd) pathway. Ninety-two research schools were ranked into three tiers. Ranking was correlated with the presence of a ClinEd track. Thirty promotion documents (ten from each tier) were analyzed to identify common criteria. Differences in guidelines between tiers were assessed by the frequency distribution of criteria. Tier 1 had a significantly greater proportion of schools with a ClinEd track than tier 2 (73% versus 44%, p < 0.05). Thirty-nine criteria were identified and organized into four categories teaching (13), scholarship (12), service/clinical excellence (7), and research (7). The top five included meeting presentations, trainee evaluations, leadership in committees, development of teaching methodologies and materials, and publication of book chapters. First and second tier schools were most similar in frequency distribution. The criteria for the ClinEd promotion track still vary across institutions, though many commonalities exist. A handful of innovative criteria reflect the changing structure of modern health care systems, such as incorporation of online teaching modules and quality improvement efforts. As health care changes, guidelines and incentive structures for faculty should change as well. The information gathered may provide promotion committees with a more global perspective on the types of academic activity valued by modern-day institutions to aid in the national standardization of this pathway and to assist in faculty mentoring.

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

RadLex - German version: a radiological lexicon for indexing image and report information

Purpose: Since 2003 the Radiological Society of North America (RSNA) has been developing a lexicon of standardized radiological terms (RadLex) intended to support the structured reporting of imaging observations and the indexing of teaching cases. The aim of this study was to translate the first version of the lexicon (1 - 2007) into German and to implement a language-independent online term browser. Materials and Methods: RadLex version 1 - 2007 contains 6303 terms in nine main categories. Two radiologists independently translated the lexicon using medical dictionaries. Terms translated differently were revised and translated by consensus. For the development of an online term browser, a text processing algorithm called morphosemantic indexing was used which splits up words into small semantic units and compares those units to language-specific subword thesauri. Results: In total 6240 of 6303 terms (99 %) were translated. Of those terms 3965 were German, 1893 were Latin, 359 were multilingual, and 23 were English terms that are also used in German and were therefore maintained. The online term browser supports a language-independent term search in RadLex (German/English) and other common medical terminology (e.g., ICD 10). The term browser displays term hierarchies and translations in different frames and the complexity of the result lists can be adapted by the user. Conclusion: RadLex version 1 - 2007 developed by the RSNA is now available in German and can be accessed online through a term browser with an efficient search function. This is an important precondition for the future comparison of national and international indexed radiological examination results and the interoperability between digital teaching resources.

Machine Learning and Radiology

Science.gov (United States)

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

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

Inventory simulation tools: Separating nuclide contributions to radiological quantities

Science.gov (United States)

Gilbert, Mark R.; Fleming, Michael; Sublet, Jean-Christophe

2017-09-01

The activation response of a material is a primary factor considered when evaluating its suitability for a nuclear application. Various radiological quantities, such as total (becquerel) activity, decay heat, and γ dose, can be readily predicted via inventory simulations, which numerically evolve in time the composition of a material under exposure to neutron irradiation. However, the resulting data sets can be very complex, often necessarily resulting in an over-simplification of the results - most commonly by just considering total response metrics. A number of different techniques for disseminating more completely the vast amount of data output from, in particular, the FISPACT-II inventory code system, including importance diagrams, nuclide maps, and primary knock-on atom (PKA) spectra, have been developed and used in scoping studies to produce database reports for the periodic table of elements. This paper introduces the latest addition to this arsenal - standardised and automated plotting of the time evolution in a radiological quantity for a given material separated by contributions from dominant radionuclides. Examples for relevant materials under predicted fusion reactor conditions, and for bench-marking studies against decay-heat measurements, demonstrate the usefulness and power of these radionuclide-separated activation plots.

To determine the clinical characteristic, clinical presentations and radiological features of diopathic granulomatous mastitis, and the best treatment approaches of this clinical entity. Between 1996 and 2003 the files and histopathology reports of 25 patients with granulomatous mastitis at King Abdul-Aziz University Hospital Jeddah, Kindom of Saudi Arabia were reviewed. The data were analyzed and a Medline search was carried out from 1970 to 2003 to review relevant cases. The age of patients ranged from 24-66 years and the mean age was 36.6+-9.43 years. All patients were females. The most common clinical presentation was palpable tender mass. The most common mammographic finding was ill-defined mass. However, mixed hypo- and hyper-echogenic lesions with tubular connections were the common ultrasonic findings. Treatment approaches were conservative or surgical excision or steroid. Conservative treatment associated with the higher rate of complications, while treatment with steroid showed complete remission of disease. Idiopathic granulomatous mastitis is a rare, benign breast disease that is usually underestimated or misdiagnosed. The clinical and radiological features resemble those of infectious mastitis or breast carcinoma. Early recognition and initiation of steroid treatment will result in complete remission of the disease and prevent complications. (author)

The Development and Preliminary Application Ofplant Quarantine Remote Teaching System Inchina

Wu, Zhigang; Li, Zhihong; Yang, Ding; Zhang, Guozhen

With the development of modern information technology, the traditional teaching mode becomes more deficient for the requirement of modern education. Plant Quarantine has been accepted as the common course for the universities of agriculture in China after the entry of WTO. But the teaching resources of this course are not enough especially for most universities with lack base. The characteristic of e-learning is regarded as one way to solve the problem of short teaching resource. PQRTS (Plant Quarantine Remote Teaching System) was designed and developed with JSP (Java Sever Pages), MySQL and Tomcat in this study. The system included many kinds of plant quarantine teaching resources, such as international glossary, regulations and standards, multimedia information of quarantine process and pests, ppt files of teaching, and training exercise. The system prototype implemented the functions of remote learning, querying, management, examination and remote discussion. It could be a tool for teaching, teaching assistance and learning online.

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.

International Nuclear Information System (INIS)

Sendra-Portero, Francisco; Torales-Chaparro, Oscar E.; Ruiz-Gómez, Miguel J.; Martínez-Morillo, Manuel

2013-01-01

Purpose: To demonstrate that virtual lectures can substitute conventional lectures in radiology education for medical students. Methods and materials: During the course 2005–2006, 89 out from 191 (46.6%) third year students of a subject entitled “General Radiology”, participated voluntarily in a pilot study including 22 virtual lectures (Flash presentations translated from the same PowerPoint presentations of conventional lectures, adding recorded narration and navigation tools). Participants (P) studied by means of virtual lectures, while non-participants (NP) assisted to conventional lectures. The results of the final oral exam classified from 0 to 3, and a 60-questions evaluation on image interpretation were used to compare both groups after training. Finally, 34 students from the group P (38.2%) fulfilled a 10-points scale quality survey about the project. Results: Final exam qualifications were significantly higher for P than for NP (2.11 ± 0.85 versus 1.73 ± 1.04) as well as the number of correct answers of the evaluation on image interpretation (24.2 ± 6.2 versus 21.2 ± 5.4), but differences could obey to different attitudes between both groups. The usefulness of virtual lectures to learn General Radiology obtained the highest global scoring (8.82 ± 1.00). Contents were generally better evaluated than the design of the presentations. Conclusion: Virtual lectures can substitute conventional lectures in radiology education for medical students with no detriment to students’ learning. Their potential advantage is that magisterial lectures can be used to discuss contents with students in a more participative way if virtual lectures are provided before

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. Copyright © 2012. Published by Elsevier B.V.

The use of artificial ionizing radiation has also been employed in several areas, namely: medicine, agriculture, industry, ink curing etc. However, the use of radiation for medical purposes of diagnosis or therapy is being treated with more attention due to its increased use and the use of simulators object for quality control and training of professionals. The phantoms and are used to aid radiographic procedures, they may simulate a part of the body, both in its form as mass, density, and attenuation. The objective of this work was the development and application of liver anthropomorphic phantom for use in diagnostic radiology and training professionals. The construction of the liver anthropomorphic phantom was through literature and it was noticed that the use of phantoms are relatively low. For the construction of the mold of the phantom was used an adult human liver with early cirrhosis that was preserved in formalin for teaching demonstrations in Prof. Human Anatomy Museum collection Osvaldo Cruz of milk from the Federal University of Sergipe. With this work, we emphasize the need for the control program and quality assurance in radiology doctor to ensure image quality and low exposure of patients and professionals, since the radiological examinations are extremely important, because its contribution decisively in medical diagnosis.

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.

1997-01-01

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

Radiological controls integrated into design

Energy Technology Data Exchange (ETDEWEB)

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

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.

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.

The development of multidisciplinary team meetings (MDTMs) for radiology and pathology is a burgeoning area that increasingly impacts on work processes in both of these departments. The aim of this study was to examine work processes and quantify the time demands on radiologists and pathologists associated with MDTM practices at a large teaching hospital. The observations reported in this paper reflect a general trend affecting hospitals and our conclusions will have relevance for others implementing clinical practice guidelines.

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.)

In this paper we describe the methodology of teaching learning process that permits integration of theory and practice for the transmission of the three fundamental pillars of Mental Health Programme: learning doctor patient relationship, situational diagnosis and team work. The number and diversity of students in each course is a challenge for the teacher, who sustains the idea that the doctor patient relationship is learned starting from the teacher student relationship. Like patients, each student is unique. We describe the method used: to divide students into groups, that throughout the year become working-teams with the intention of practicing Medicine with an interpersonal relationship concept (with the patient, his or her family, his social circle, with colleagues, nursery, assistants and institutions). Each unit is coordinated by a group teacher. They have periodic meetings with the students (in the Balint Junior groups' method). The students have to create the contents and participate in the dynamics of the classes. This methodology changes the traditional vision and the teacher has the function of an organizer and facilitator of learning. It includes: a. Group division, b. Preparation of a file, c. Workshop, d. Teaching and e. Evaluation Teaching learning is conducive to a facilitating atmosphere through different resources like story telling, diagrams, drawings, movies, literature, use of plastic, role playing, elaborating scenes, characters and the file, evidence of all the activities.

Integrating interactive three-dimensional post-processing software into undergraduate radiology teaching might be a promising approach to synergistically improve both visual-spatial ability and radiological skills, thereby reducing students' deficiencies in image interpretation. The purpose of this study was to test our hypothesis that a hands-on radiology course for medical students using interactive three-dimensional image post-processing software improves radiological knowledge, diagnostic skills and visual-spatial ability. A hands-on radiology course was developed using interactive three-dimensional image post-processing software. The course consisted of seven seminars held on a weekly basis. The 25 participating fourth- and fifth-year medical students learnt to systematically analyse cross-sectional imaging data and correlated the two-dimensional images with three-dimensional reconstructions. They were instructed by experienced radiologists and collegiate tutors. The improvement in radiological knowledge, diagnostic skills and visual-spatial ability was assessed immediately before and after the course by multiple-choice tests comprising 64 questions each. Wilcoxon signed rank test for paired samples was applied. The total number of correctly answered questions improved from 36.9±4.8 to 49.5±5.4 (pability by 11.3% (psoftware into undergraduate radiology education effectively improves radiological reasoning, diagnostic skills and visual-spatial ability, and thereby even diagnostic skills for imaging modalities not included in the course.

The balanced scorecard (BSC) represents a comprehensive management tool for organizations with the aim to focus all activities on a chosen strategy. Targets for various perspectives of the environment such as the customer, financial, process, and potential perspective are linked with concrete measures, and cause-effect relationships between the objectives are analyzed. This article shows that the BSC can also be used for the comprehensive control of a radiology department and thus provides a meaningful contribution in organizing the various diagnostic and treatment services, the management of complex clinical environment and can be of help with the tasks in research and teaching. © Georg Thieme Verlag KG Stuttgart · New York.

Training Workers to use Localized Ventilation for Radiological Work

International Nuclear Information System (INIS)

WAGGONER, L.O.

2000-01-01

Work on radiological systems and components needs to be accomplished using techniques that reduce radiation dose to workers, limit contamination spread, and minimize radioactive waste. One of the best methods to control contamination spread is to use localized ventilation to capture radioactive material and keep it from spreading. The Fluor Hanford ALARA Center teaches workers how to use ventilation in partnership with other engineered controls and this has resulted in improved work practices, minimized the impact on adjacent work operations, and decreased the amount of radioactive waste generated. This presentation will emphasize how the workers are trained to use localized ventilation for contamination control

Lee, Aoife M; Lee, Michael J

2018-02-01

Interventional radiology (IR) has grown rapidly over the last 20 years and is now an essential component of modern medicine. Despite IR's increasing penetration and reputation in healthcare systems, IR is poorly taught, if taught at all, in most medical schools. Medical students are the referrers of tomorrow and potential IR recruits and deserve to be taught IR by expert IRs. The lack of formal IR teaching curricula in many medical schools needs to be addressed urgently for the continued development and dissemination of, particularly acute, IR services throughout Europe. We call on IRs to take up the baton to teach IR to the next generation of doctors.

The hidden curriculum in radiology residency programs: A path to isolation or integration?

Purpose: In this qualitative case study involving five academic Radiology centres across Canada, the authors seek to identify the hidden curriculum. Methods: A qualitative case study methodology was used for its potential to explore and provide rich descriptions and allow for the in-depth analysis of multiple data sources that include official institutional documents, surveys, observations and interviews (including undergraduate students, postgraduate, radiologists, imaging scientists, residents, faculty and administrators). This study relied on 48 interviews and involved primary data analysis by the core research team, and a secondary analysis by external examiners. Results: The results revealed that in four of the five major centres studied, a hidden curriculum of isolation prevailed, reinforcing an image of the radiologist as an independent operator within an organization dependent upon collaboration for optimal performance. The fifth site exhibited a hidden curriculum of collaboration and support, although the messages received were conflicting when addressing issues around teaching. Conclusions: The authors conclude by noting two possibilities for medical imaging departments to consider that of isolation or that of integration. They examine the implications of each and propose a way forward that situates Radiology as the crossroads of medicine. As such, the need for a new, generative metaphor reasserts the importance of recognizing the role and function of scholarship in teaching and learning contexts across Canada

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.

Klobuka, Andrew J; Lee, John; Buranosky, Raquel; Heller, Matthew

2018-02-13

Current radiology and internal medicine (IM) residents have trained to varying degrees depending on program in the post picture archiving and communication systems implementation era and thus have largely missed out on the benefits of in-person, 2-way communication between radiologists and consulting clinicians. The purpose of this study is to broadly explore resident perspectives from these groups on the desire for personal contact between radiologists and referring physicians and the effect of improved contact on clinical practice. A radiology rounds was implemented in which radiology residents travel to the IM teaching service teams to discuss their inpatients and review ordered imaging biweekly. Surveys were given to both cohorts following 9 months of implementation. A total of 23/49 diagnostic radiology (DR) and 72/197 IM residents responded. In all, 83% of DR and 96% of IM residents desired more personal contact between radiologists and clinicians. Of all, 92% of DR residents agree that contact with referring clinicians changes their approach to a study, 96% of IM residents agree that personal contact with a radiologist has changed patient management in a way that they otherwise would not have done having simply read a report, 85% of DR residents report that more clinician contact will improve resource use, and 96% report that it will improve care quality. Furthermore, 99% of IM residents report that increased access to a radiologist would make selecting the most appropriate imaging study easier in various clinical scenarios. A majority of IM residents prefer radiology reports that provide specific next-step recommendations and that include arrows/key-image series. We conclude that the newest generation of physicians is already attuned to the value of a radiologist who plays an active, in-person role in the clinical decision-making process.

2003-01-01

This paper overviews the curricula of nuclear medicine (NM) undergraduate training in 34 Central and Eastern European (CEE) and 37 European Union (EU) medical faculties. The data show enormous variation in the number of hours devoted to nuclear medicine, varying between 1-2 to 40 hours and highly differentiated concepts/ideas of nuclear medicine training in particular countries. In most EU countries this teaching is integrated with that of radiology or clinical modules, also with training in clinical physiology. In many CEE countries teaching and testing of NM are independent, although integration with other teaching modules is frequent. The paper discusses the differences in particular approaches to nuclear medicine teaching. (author)

A graphical user interface for diagnostic radiology dosimetry using Monte Carlo (MCNP) simulation

Collins, P.J.; Gorbatkov, D.; Schultz, F.W.

Monte Carlo methods (for example, MCNP, EGGS4) are the 'gold standard' for both external and internal dosimetry in humans. These powerful simulation tools are, however, general-purpose codes and consequently do not provide a simple user interface for specific dosimetry tasks. We have developed a graphical user interface, for external radiation dosimetry (diagnostic radiology) using MCNP and an anthropomorphic mathematical phantom (Adam/Eva), which enables convenient modification and processing of the MCNP input and output files. The input form displays a colour coded, 3D representation of the phantom with a superimposed 'beam' for the required x-ray projection. The phantom can be rotated through 360 degrees and a transverse section at the level of the mid-point of the beam is also displayed. Text fields enable entry of input data (beam dimensions, source position, kVp, total filtration, focus-to-skin distance). A pull-down menu enables the user to select from 22 standard radiographic views. A standard projection can be modified, or new projection data entered if required. The input program modifies the MCNP input file and initiates processing. An output form displays the organ doses, normalised to unit skin entrance dose (with backscatter) (SED). The user can also enter the SED (calculated or measured) for a particular machine, to obtain the effective dose. To validate the program, the results for a PA Chest study (80 kVp, 2.5 mm Al total filtration) were compared with NRPB data (Jones and Wall, 1985). In conclusion, a convenient and reliable graphical user interface has been developed for MCNP, which enables dosimetry calculation for a full range of diagnostic radiological studies. (author)

2015-05-01

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

2002-01-01

Purpose: The ASTRO Joint Working Group on Radiobiology Teaching, a committee composed of members having affiliations with several national radiation oncology and biology-related societies and organizations, commissioned a survey designed to address issues of manpower, curriculum standardization, and instructor feedback as they relate to resident training in radiation biology. Methods and Materials: Radiation biology instructors at U.S. radiation oncology training programs were identified and asked to respond to a comprehensive electronic questionnaire dealing with instructor educational background, radiation biology course content, and sources of feedback with respect to curriculum planning and resident performance on standardized radiation biology examinations. Results: Eighty-five radiation biology instructors were identified, representing 73 radiation oncology residency training programs. A total of 52 analyzable responses to the questionnaire were received, corresponding to a response rate of 61.2%. Conclusion: There is a decreasing supply of instructors qualified to teach classic, and to some extent, clinical, radiobiology to radiation oncology residents. Additionally, those instructors with classic training in radiobiology are less likely to be comfortable teaching cancer molecular biology or other topics in cancer biology. Thus, a gap exists in teaching the whole complement of cancer and radiobiology curricula, particularly in those programs in which the sole responsibility for teaching falls to one faculty member (50% of training programs are in this category). On average, the percentage of total teaching time devoted to classic radiobiology (50%), clinical radiobiology (30%), and molecular and cancer biology (20%) is appropriate, relative to the current makeup of the board examination. Nevertheless large variability exists between training programs with respect to the total number of contact hours per complete radiobiology course (ranging from

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

Assessment of radiological protection systems among diagnostic radiology facilities in North East India.

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 2014 Institute of Medicine report, Graduate Medical Education that Meets the Nation's Health Needs , challenged the current graduate medical training process and encouraged new opportunities to redefine the fundamental skills and abilities of the physician workforce. This workforce should be skilled in critically evaluating the current systems to improve care delivery and health. To meet these goals, current challenges, motivations, and educational models at the medical school and graduate medical education levels related to formal training in nonclinical aspects of medicine, especially critical thinking, are reviewed. Our diagnostic radiology training program is presented as a "case study" to frame the review.

The private-practice perspective of the manpower crisis in radiology: greener pastures?

Science.gov (United States)

Swayne, Lawrence C

2004-11-01

Rising consumer expectations and a rapidly aging population point to a long-term shortage of all physicians, including radiologists. While attention has been drawn to the escalating manpower crisis in academic radiology departments, the private-practice perspective has been generally overlooked. Although clinical workloads and income are higher in private practice, studies have shown higher satisfaction levels (likely because of a greater variety of work) among academic radiologists. As the distinction between community and teaching hospitals has become increasingly blurred, there is now considerable overlap in the skill sets, sources of job satisfaction, and stresses that are encountered in both practice settings. Perhaps more than at any time in the recent past, diagnostic radiologists in academic and private practice share more in common than any perceived differences. Both groups must work together in concert with the ACR to address the growing manpower shortage, as well as the other challenges that confront diagnostic radiology at the beginning of the 21st century.

Pediatric radiology

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

Attention for pediatric interventional radiology

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

Nuclear medicine resources in the internet

The internet is a global collection of networked computers linked by a set of protocols which allows the otherwise disperate computer systems to communicate with each other. In contrast to text-only data available previously, the World Wide Web allows multimedia content to be available on the internet. Graphics can now likewise be used as links. The development of World Wide Web client software such as Mosaic, or the currently more popular Netscape Navigator, makes linking from one document to another (colloquially referred to as 'surfing the Net') fast and simple. While these software are commonly called Web browsers their function extends to the other internet services such as e-mail, file transfer protocol, remote login, Gopher and WAIS. A prototype application being developed as a case-based teaching file which could include clinical data and case discussion, aside of course from the nuclear medicine and related images. Contributions from various institutions can be made available on their own servers and linked together through hypertext. Examples of these are websites of the Mallinckrodt Institute of Radiology and the Joint Program in Nuclear Medicine of the Harvard Medical School. The university of Iowa also has its Virtual Hospital, a collection of clinical cases with radiologic images. Most major universities and medical centers have websites where information on on-going research, facilities and personnel are made available. Links to various special interest discussion groups (e.g. those developing the common image file format) are also accessible and the documents often contain further links to related fields in nuclear technology. The very nature of the hypertext transfer protocol of the World Wide Web makes it a relatively simple matter for a developer of a teaching system to include links to necessary resources. It is envisioned that an internet-based teaching module will be incorporated in some nuclear medicine training programs in the United States

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

Dysphagia is a common complaint in patients presenting for radiological or endoscopic examination of the esophagus and is usually due to functional or structural abnormalities of the esophageal body or esophagogastric region. The authors review the radiological evaluation of the esophagus and esophagogastric region in patients with esophageal dysphagia and discuss the roentgenographic techniques used, radiological efficacy for common structural disorders, and evaluation of esophageal motor function. Comparison is made with endoscopy in assessing dysphagia, with the conclusion that the radiological examination be used initially in patients with this complaint.

For several years a reference center of the UCV has been working on the project VEN/9/007 on dose reduction in diagnostic radiology sponsored by the IAEA. The dose and quality image was evaluated for different types of radiological study (conventional radiology, CT, mammography, interventional radiology) in different facilities at Caracas and others regions of the Venezuela. TL dosimeters were used to assess dose and reduction in dose. Based on the recommendations given by CEC documents on diagnostic quality criteria, a quality control program in radiological protection of patients and staff has been developed, for example: Pilot study by using TLD in personnel radiation monitoring. Comparative study between high and low kVp in chest. Evaluation and dose reduction in chest pediatric. Reduction of radiation dose in studies of billiards via Quality Image and reduction of the dose in studies of colon by enema. Radiation dose of staff in fluoroscopy procedures. Evaluation and dose reduction in dental radiography in public Institutions. A mammography accreditation program for Venezuela, applied to public hospitals. (author)

Accessing files in an Internet: The Jade file system

Science.gov (United States)

Peterson, Larry L.; Rao, Herman C.

1991-01-01

Jade is a new distribution file system that provides a uniform way to name and access files in an internet environment. It makes two important contributions. First, Jade is a logical system that integrates a heterogeneous collection of existing file systems, where heterogeneous means that the underlying file systems support different file access protocols. Jade is designed under the restriction that the underlying file system may not be modified. Second, rather than providing a global name space, Jade permits each user to define a private name space. These private name spaces support two novel features: they allow multiple file systems to be mounted under one directory, and they allow one logical name space to mount other logical name spaces. A prototype of the Jade File System was implemented on Sun Workstations running Unix. It consists of interfaces to the Unix file system, the Sun Network File System, the Andrew File System, and FTP. This paper motivates Jade's design, highlights several aspects of its implementation, and illustrates applications that can take advantage of its features.

2007-05-01

Our objective is to present a simple method for converting movie clips to animated GIFs (graphics interchange format) using Photoshop. Although animated GIF is a more reliable format than movie clips (e.g., AVI and QuickTime) for presenting dynamic data sets in PowerPoint presentations, this output format is not available on most radiology workstations. Therefore, many academic radiologists still experience the problem of incompatible codecs and missing file links when trying to show movie clips in their PowerPoint presentations. One way to resolve this issue is to convert the movie clips to animated GIFs. In this article, we provide a simple method for this conversion using Photoshop--a common software application used by radiologists.

Jedrusik, P.; Preisack, M.; Dammann, F.

2005-01-01

Purpose: evaluation of the applicability of the flash format for the production of radiological learning objects used in an e-learning environment. Material and methods: five exemplary learning objects with different didactic purposes referring to radiological diagnostics are presented. They have been intended for the use within the multimedia, internet-based e-learning environment LaMedica. Interactive learning objects were composed using the Flash 5.0 software (Macromedia, San Francisco, USA) on the basis of digital CT and MR images, digitized conventional radiographs and different graphical elements prepared as TIFF files or in a vector graphics format. Results: after a short phase of initial skill adaptation training, a radiologist author was soon able to create independently all learning objects. The import of different types of images and graphical elements was carried out without complications. Despite manifold design options, handling of the program is easy due to clear arrangement and structure, thus enabling the creation of simple as well as complex learning objects that provided a high degree of attractiveness and interaction. Data volume and bandwidth demand for online use was significantly reduced by the flash format compression without a substantial loss of visual quality. (orig.)

The NASA SCI Files is an Emmy award-winning series of instructional programs for grades 3-5. Produced by the NASA Center for Distance Learning, programs in the series are research-, inquiry-, standards-, teacher- and technology-based. Each NASA SCI Files program (1) integrates mathematics, science, and technology; (2) uses Problem-Based Learning (PBL) to enhance and enrich the teaching and learning of science; (3) emphasizes science as inquiry and the scientific method; (4) motivates students to become critical thinkers and active problem solvers; and (5) uses NASA research, facilities, and personnel to raise student awareness of careers and to exhibit the "real-world" application of mathematics, science, and technology. In April 2004, 1,500 randomly selected registered users of the NASA SCI Files were invited to complete a survey containing a series of questions. A total of 263 surveys were received. This report contains the quantitative and qualitative results of that survey.

Podcasts are digital files very popular in several and very distinct areas. In higher education, they have been explored in a multitude of ways mainly to support teaching and learning processes. The study here described focuses the integration of podcasts in Heredity and Evolution, a course from the Biology and Geology Degree Program at University of Minho, Portugal. It aimed to introduce podcasts in the teaching/learning context, to empirically study different dimensions of podcasting, and to evaluate students' acceptance and receptiveness to the pedagogical use of this technology. Five informative podcasts and three with feedback were produced and delivered. All the students listened to the audio files and considered the episodes audible and clear, their preference going to episodes of short or moderate length and containing summaries, study guidelines or syllabus contents. Students judged extremely valuable the integration of this technology in learning and showed receptiveness to podcasting in other courses. Curiously, in spite of owning mobile devices, students clearly favored the use of personal computers to listen to the podcasts. This student acceptance and openness to podcasting has been encouraging its pedagogical application in other teaching courses. The episodes produced often maintain the characteristics identified as the best by the students of this study but the pedagogical approach has been moving to a more student-centered learning situation, with students as podcasts producers. © 2016 by The International Union of Biochemistry and Molecular Biology, 44(5):429-432, 2016. © 2016 The International Union of Biochemistry and Molecular Biology.

Atypical sub-trochanteric and femoral shaft fractures have been reported in patients treated with bisphosphonates. Their incidence has been determined from registered data analysis using international codes. Therefore, the aim of our study was to estimate the real frequency of typical and atypical sub-trochanteric or diaphyseal fractures, based on radiological and clinical data compared to registered data. In the registers of three large French University Hospitals, patients identified with International Classification of Diseases, 10th Revision diagnosis codes for sub-trochanteric or diaphyseal fracture were selected. Frequencies of ordinary and atypical fractures were calculated after both registered data, radiological and clinical files analysis. Among the 4592 patients hospitalized for a femoral fracture over 5 years, 574 were identified to have had a sub-trochanteric or femoral shaft fracture. 47.7% of the sub-trochanteric and femoral shaft fractures were misclassified, predominantly in the sub-trochanteric fractures subset. 12 patients had an atypical fracture (4% of the sub-trochanteric and femoral shaft fractures) and 11 fractures presented radiological features of atypical fractures, whereas clinical files analysis revealed they were pathological or traumatic fractures. Atypical fractures frequency is very low. Because of their low frequency and the unreliability of registered databases, the risk of atypical fractures is very difficult to estimate retrospectively. A prospective study is needed to clarify the risk factors associated with these fractures. Copyright © 2012 Société française de rhumatologie. Published by Elsevier SAS. All rights reserved.

 To compare the learning benefit of three different teaching strategies on the interpretation of emergency cerebral computed tomography (CT) pathologies by medical students.  Three groups of students with different types of teaching (e-learning, interactive teaching, and standard curricular education in neuroradiology) were tested with respect to the detection of seven CT pathologies. The test results of each group were compared for each CT pathology using the chi-square test. A p-value ≤ 0.05 was considered to be significant.  Opposed to the results of the comparison group (curricular education), the e-learning group and interactive teaching tutorial group both showed a significantly better performance in detecting hyperdense middle cerebral artery sign (p = 0.001 and p e-learning group, with statistical significance in the latter (p = 0.03 and p e-learning module group with respect to reading CT scans with slightly different advantages. Thus, the introduction of new learning methods in radiological education might be reasonable at an undergraduate stage but requires learning content-based considerations.   · E-learning can offer benefits regarding the reading of cerebral CT scans by students. · Interactive tutorial can offer benefits regarding the reading of cerebral CT scans by students. · E-learning and interactive tutorial feature different strengths for student learning in radiology. · Application of interactive teaching methods in radiology requires learning content-based considerations. · Groth M, Barthe KG, Riemer M et al.

Diagnostic imaging, a 'parallel' discipline. Can current technology provide a reliable digital diagnostic radiology department

International Nuclear Information System (INIS)

Moore, C.J.; Eddleston, B.

1985-01-01

Only recently has any detailed criticism been voiced about the practicalities of the introduction of generalised, digital, imaging complexes in diagnostic radiology. Although attendant technological problems are highlighted the authors argue that the fundamental causes of current difficulties are not in the generation but in the processing, filing and subsequent retrieval for display of digital image records. In the real world, looking at images is a parallel process of some complexity and so it is perhaps untimely to expect versatile handling of vast image data bases by existing computer hardware and software which, by their current nature, perform tasks serially.

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

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

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 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.

Radioactive decay data tables: A handbook of decay data for application to radiation dosimetry and radiological assessments

Kocher, D. C.; Smith, J. S.

Decay data are presented for approximately 500 radionuclides including those occurring naturally in the environment, those of potential importance in routine or accidental releases from the nuclear fuel cycle, those of current interest in nuclear medicine and fusion reactor technology, and some of those of interest to Committee 2 of the International Commission on Radiological Protection for the estimation of annual limits on intake via inhalation and ingestion for occupationally exposed individuals. Physical processes involved in radioactive decay which produce the different types of radiation observed, methods used to prepare the decay data sets for each radionuclide in the format of the computerized evaluated nuclear structure data file, the tables of radioactive decay data, and the computer code MEDLIST used to produce the tables are described. Applications of the data to problems of interest in radiation dosimetry and radiological assessments are considered as well as the calculations of the activity of a daughter radionuclide relative to the activity of its parent in a radioactive decay chain.

Long term file migration. Part I: file reference patterns

International Nuclear Information System (INIS)

Smith, A.J.

1978-08-01

In most large computer installations, files are moved between on-line disk and mass storage (tape, integrated mass storage device) either automatically by the system or specifically at the direction of the user. This is the first of two papers which study the selection of algorithms for the automatic migration of files between mass storage and disk. The use of the text editor data sets at the Stanford Linear Accelerator Center (SLAC) computer installation is examined through the analysis of thirteen months of file reference data. Most files are used very few times. Of those that are used sufficiently frequently that their reference patterns may be examined, about a third show declining rates of reference during their lifetime; of the remainder, very few (about 5%) show correlated interreference intervals, and interreference intervals (in days) appear to be more skewed than would occur with the Bernoulli process. Thus, about two-thirds of all sufficiently active files appear to be referenced as a renewal process with a skewed interreference distribution. A large number of other file reference statistics (file lifetimes, interference distributions, moments, means, number of uses/file, file sizes, file rates of reference, etc.) are computed and presented. The results are applied in the following paper to the development and comparative evaluation of file migration algorithms. 17 figures, 13 tables

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.

Introduction Dynamic cueing is an effective way of stimulating perception of regions of interest within radiological images. This study explores the impact of a novel teaching tool using dynamic cueing for lesion detection on plain chest radiographs. Materials and methods Observer performance studies were carried out where 36 novices examined 30 chest images in random order. Half of these contained between one and three simulated pulmonary nodules. Three groups were investigated: A (control: no teaching tool), B (retested immediately after undergoing the teaching tool) and C (retested a week after undergoing the teaching tool). The teaching tool involved dynamically displaying the same images with and without lesions. Results were compared using Receiver Operating Characteristics (ROC), sensitivity and specificity analyses. Results The second reading showed significantly greater area under the ROC curve (Az value) (pchest radiographs in the short term.

The authors hypothesized that ownership of a mobile electronic device would result in more time spent learning radiology. Current trends in radiology residents' studying habits, their use of electronic and printed radiology learning resources, and how much of the funds allotted to them are being used toward printed vs electronic education tools were assessed in this study. A survey study was conducted among radiology residents across the United States from June 13 to July 5, 2011. Program directors listed in the Association of Program Directors in Radiology e-mail list server received an e-mail asking for residents to participate in an online survey. The questionnaire consisted of 12 questions and assessed the type of institution, the levels of training of the respondents, and book funds allocated to residents. It also assessed the residents' study habits, access to portable devices, and use of printed and electronic radiology resources. Radiology residents are adopters of new technologies, with 74% owning smart phones and 37% owning tablet devices. Respondents spend nearly an equal amount of time learning radiology from printed textbooks as they do from electronic resources. Eighty-one percent of respondents believe that they would spend more time learning radiology if provided with tablet devices. There is considerable use of online and electronic resources and mobile devices among the current generation of radiology residents. Benefits, such as more study time, may be obtained by radiology programs that incorporate tablet devices into the education of their residents. Copyright © 2012 American College of Radiology.

In cooperation with the US Army, Georgetown University Medical Center (GUMC) deployed a teleradiology network to sites in Bosnia-Herzegovina, Hungary, and Germany in early 1996. This deployment was part of Operation Primetime III, a military project to provide state-of-the-art medical care to the 20,000 US troops stationed in Bosnia-Herzegovina.In a three-month time frame from January to April 1996, the Imaging Sciences and Information Systems (ISIS) Center at GUMC worked with the Army to design, develop, and deploy a teleradiology network for the digital storage and transmission of radiology images. This paper will discuss some of the problems associated with sending large files over communications networks with significant delays such as those introduced by satellite transmissions.Radiology images of up to 10 megabytes are acquired, stored, and transmitted over the wide area network (WAN). The WAN included leased lines from Germany to Hungary and a satellite link form Germany to Bosnia-Herzegovina. The communications links provided at least a T-1 bandwidth. The satellite link introduces a round-trip delay of approximately 500 milliseconds. This type of high bandwidth, high delay network is called a long fat network. The images are transferred across this network using the Transmission Control Protocol (TCP/IP). By modifying the TCP/IP software to increase the window size, the throughput of the satellite link can be greatly improved.

Comparison of the distribution of non-radiological and radiological fatal risk in Ontario industries (addendum)

Davis, C.K.; Forbes, W.F.; Hayward, L.M.

1986-09-01

Occupational limits for exposure to ionizing radiation, in force in Canada, are based on recommendations of international bodies, particularly the International Commission on Radiological Protection (ICRP). To determine whether the ICRP assertions concerning the similarity of the distributions of occupational risk at the higher risk levels (from non-radiation and from radiation work) to Canada a study of the high end of the distributions of non-radiological risk of occupational fatalities in the province of Ontario was performed. For the present study total doses from exposure to sources of ionizing radiation for Ontario workers were converted to relative risk rates to allow direct comparison with the non-radiological results. In addition, absolute values for the radiological risk rates (RRR) were derived. The radiological risk estimates are based on workers who work both from nuclear reactions and from X-rays. The conclusion is made that the radiological and non-radiological risk rate (NRRR) distributions are similar in shape, but the RRR are approximately 1 to 27 percent of the NRRR, depending on the industry concerned

A Planning Tool for Estimating Waste Generated by a Radiological Incident and Subsequent Decontamination Efforts - 13569

Management of debris and waste from a wide-area radiological incident would probably constitute a significant percentage of the total remediation cost and effort. The U.S. Environmental Protection Agency's (EPA's) Waste Estimation Support Tool (WEST) is a unique planning tool for estimating the potential volume and radioactivity levels of waste generated by a radiological incident and subsequent decontamination efforts. The WEST was developed to support planners and decision makers by generating a first-order estimate of the quantity and characteristics of waste resulting from a radiological incident. The tool then allows the user to evaluate the impact of various decontamination/demolition strategies on the waste types and volumes generated. WEST consists of a suite of standalone applications and Esri R ArcGIS R scripts for rapidly estimating waste inventories and levels of radioactivity generated from a radiological contamination incident as a function of user-defined decontamination and demolition approaches. WEST accepts Geographic Information System (GIS) shape-files defining contaminated areas and extent of contamination. Building stock information, including square footage, building counts, and building composition estimates are then generated using the Federal Emergency Management Agency's (FEMA's) Hazus R -MH software. WEST then identifies outdoor surfaces based on the application of pattern recognition to overhead aerial imagery. The results from the GIS calculations are then fed into a Microsoft Excel R 2007 spreadsheet with a custom graphical user interface where the user can examine the impact of various decontamination/demolition scenarios on the quantity, characteristics, and residual radioactivity of the resulting waste streams.

Efforts to develop Picture Archiving and Communications Systems (PACS) for the last ten years have concentrated mainly on developing systems for primary interpretation of digital radiological images. Much less attention has been paid to the clinical aspects of the radiology process. Clinical radiology services are an important component of the overall care delivery process, providing information and consultation services to referring physicians, the customers of radiology, in a timely fashion to aid in care decisions. Information management systems (IMS) are playing an increasingly central role in the care delivery process. No suitable commercial PACS or IMS products were available that could effectively provide for the requirements of the clinicians. We endeavored to fill this void at our institution by developing a system to deliver images and text reports electronically on-demand to the referring physicians. This system has evolved substantially since initial deployment eight years ago. As new technologies become available they are evaluated and integrated as appropriate to improve system performance and manageability. Not surprisingly, the internet and World Wide Web (WWW) technology has had the greatest impact on system design in recent years. Additional features have been added over time to provide services for teleradiology, teaching, and research needs. We also discovered that these value-added services give us a competitive edge in attracting new business to our department. Commercial web-based products are now becoming available which do a satisfactory job of providing many of these clinical services. These products are evaluated for integration into our system as they mature. The result is a system that impacts positively on patient care.

The accuracy of radiology speech recognition reports in a multilingual South African teaching hospital

International Nuclear Information System (INIS)

Toit, Jacqueline du; Hattingh, Retha; Pitcher, Richard

2015-01-01

Speech recognition (SR) technology, the process whereby spoken words are converted to digital text, has been used in radiology reporting since 1981. It was initially anticipated that SR would dominate radiology reporting, with claims of up to 99% accuracy, reduced turnaround times and significant cost savings. However, expectations have not yet been realised. The limited data available suggest SR reports have significantly higher levels of inaccuracy than traditional dictation transcription (DT) reports, as well as incurring greater aggregate costs. There has been little work on the clinical significance of such errors, however, and little is known of the impact of reporter seniority on the generation of errors, or the influence of system familiarity on reducing error rates. Furthermore, there have been conflicting findings on the accuracy of SR amongst users with English as first- and second-language respectively. The aim of the study was to compare the accuracy of SR and DT reports in a resource-limited setting. The first 300 SR and the first 300 DT reports generated during March 2010 were retrieved from the hospital’s PACS, and reviewed by a single observer. Text errors were identified, and then classified as either clinically significant or insignificant based on their potential impact on patient management. In addition, a follow-up analysis was conducted exactly 4 years later. Of the original 300 SR reports analysed, 25.6% contained errors, with 9.6% being clinically significant. Only 9.3% of the DT reports contained errors, 2.3% having potential clinical impact. Both the overall difference in SR and DT error rates, and the difference in ‘clinically significant’ error rates (9.6% vs. 2.3%) were statistically significant. In the follow-up study, the overall SR error rate was strikingly similar at 24.3%, 6% being clinically significant. Radiologists with second-language English were more likely to generate reports containing errors, but level of seniority

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

Radiation Protection Education in Diagnostic Radiology in Uruguay

Cotelo, E.; Paolini, G.

2003-01-01

In Uruguay the lack of Radiation Protection (RP) laws makes education in medical use of ionizing radiations at University, a decisive factor of changes. The six years experience in teaching technicians, radiologists, interventional cardiologists and anesthetists in curricular lectures, continuing education courses and workshops, show the importance of a close link between educators and occupationally exposed professionals. Regarding training and education in the optimization of the procedures, it is essential that both teacher and student comprehend the exact meaning of ALARA concept. This implies that although the educator is the one who manages the physical basis of RP, the student is who teaches the educator about the procedures. This turns RP education into a dynamic process in which at the same time, both educator and student learn and teach. After the theoretical lectures, it is essential that students show their ability in applying the acquired knowledge in their everyday practice. Last nut not least, in order to fulfill the first RP principle,all medicine students need to be educated in RP and quality image criteria before the get their medical doctor degree. Our experience shows that RP education in diagnostic radiology requires an expert with both medical physics and Image technology knowledge that allow an approach to students work, language and everyday problems. Despite the fact that the main result of the Education Program is the way professionals improve their practice, another consequence was that the Regulatory Authority of the country called the teacher team to coordinate the first RP national course.

RADRELAY RADIOLOGICAL DATA LINK DEVICE

International Nuclear Information System (INIS)

Harpring, L.; Frank Heckendorn, F.

2007-01-01

The RadRelay effort developed small, field appropriate, portable prototype devices that allow radiological spectra to be downloaded from field radiological detectors, like the identiFINDER-U, and transmitted to land based experts. This communications capability was designed for the U. S. Coast Guard (USCG) but is also applicable to the Customs and Border Protection (CBP) personnel working in remote locations. USCG Level II personnel currently use the identiFINDER-U Hand-Held Radioisotope ID Devices (HHRIID) to detect radiological materials during specific boarding operations. These devices will detect not only radiological emissions but will also evaluate those emissions against a table of known radiological spectra. The RadRelay has been developed to significantly improve the functionality of HHRIID, by providing the capability to download radiological spectra and then transmit them using satellite or cell phone technology. This remote wireless data transfer reduces the current lengthy delay often encountered between the shipboard detection of unknown radiological material and the evaluation of that data by technical and command personnel. That delay is reduced from hours to minutes and allows the field located personnel to remain on station during the inspection and evaluation process

Shielding x-ray devices and issuing film badges to radiological workers in 1936 can be considered the start of radiological protection in the Philips enterprises in the Netherlands. Shielding and equipment were constantly improved based upon the dosimetry results of the filmbadges. The problem of radioactive waste led to the foundation of a central Philips committee for radiological protection in 1956, which in 1960 also issued an internal license system in order to regulate the proper precautions to be taken : workplace design and layout, technological provisions and working procedures. An evaluation of all radiological work in 1971 learnt that a stricter health surveillance program was needed to follow up the precautions issued by the license. On one hand a health surveillance program was established and on the other hand all types of radiological work were classified. In this way an obligatory and optimal health surveillance program was issued for each type of radiological work

Lee, Young Han; Song, Ho-Taek; Suh, Jin-Suck

2012-12-01

The objectives are (1) to introduce a new concept of making a quantitative computed tomography (QCT) reporting system by using optical character recognition (OCR) and macro program and (2) to illustrate the practical usages of the QCT reporting system in radiology reading environment. This reporting system was created as a development tool by using an open-source OCR software and an open-source macro program. The main module was designed for OCR to report QCT images in radiology reading process. The principal processes are as follows: (1) to save a QCT report as a graphic file, (2) to recognize the characters from an image as a text, (3) to extract the T scores from the text, (4) to perform error correction, (5) to reformat the values into QCT radiology reporting template, and (6) to paste the reports into the electronic medical record (EMR) or picture archiving and communicating system (PACS). The accuracy test of OCR was performed on randomly selected QCTs. QCT as a radiology reporting tool successfully acted as OCR of QCT. The diagnosis of normal, osteopenia, or osteoporosis is also determined. Error correction of OCR is done with AutoHotkey-coded module. The results of T scores of femoral neck and lumbar vertebrae had an accuracy of 100 and 95.4 %, respectively. A convenient QCT reporting system could be established by utilizing open-source OCR software and open-source macro program. This method can be easily adapted for other QCT applications and PACS/EMR.

2017-01-01

This study was conducted to suggest the development of a learning management system for dental radiology education using the Modular Object-Oriented Dynamic Learning Environment (Moodle). Moodle is a well-known and verified open-source software-learning management system (OSS-LMS). The Moodle software was installed on a server computer and customized for dental radiology education. The system was implemented for teaching undergraduate students to diagnose dental caries in panoramic images. Questions were chosen that could assess students' diagnosis ability. Students were given several questions corresponding to each of 100 panoramic images. The installation and customization of Moodle was feasible, cost-effective, and time-saving. By having students answer questions repeatedly, it was possible to train them to examine panoramic images sequentially and thoroughly. Based on its educational efficiency and efficacy, the adaptation of an OSS-LMS in dental school may be highly recommended. The system could be extended to continuing education for dentists. Further studies on the objective evaluation of knowledge acquisition and retention are needed

1980-01-01

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

In JENDL-3,2, the data on all the reactions having significant cross section over the neutron energy from 0.01 meV to 20 MeV are given for 340 nuclides. The object range of application extends widely, such as the neutron engineering, shield and others of fast reactors, thermal neutron reactors and nuclear fusion reactors. This is a general purpose data file. On the contrary to this, the file in which only the data required for a specific application field are collected is called special purpose file. The file for dosimetry is a typical special purpose file. The Nuclear Data Center, Japan Atomic Energy Research Institute, is making ten kinds of JENDL special purpose files. The files, of which the working groups of Sigma Committee are in charge, are listed. As to the format of the files, ENDF format is used similarly to JENDL-3,2. Dosimetry file, activation cross section file, (α, n) reaction data file, fusion file, actinoid file, high energy data file, photonuclear data file, PKA/KERMA file, gas production cross section file and decay data file are described on their contents, the course of development and their verification. Dosimetry file and gas production cross section file have been completed already. As for the others, the expected time of completion is shown. When these files are completed, they are opened to the public. (K.I.)

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

Medical radiology terminology

International Nuclear Information System (INIS)

1986-01-01

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

The radiological technologist

International Nuclear Information System (INIS)

Bundy, A.L.

1988-01-01

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

Purpose: Integrating interactive three-dimensional post-processing software into undergraduate radiology teaching might be a promising approach to synergistically improve both visual-spatial ability and radiological skills, thereby reducing students’ deficiencies in image interpretation. The purpose of this study was to test our hypothesis that a hands-on radiology course for medical students using interactive three-dimensional image post-processing software improves radiological knowledge, diagnostic skills and visual-spatial ability. Materials and methods: A hands-on radiology course was developed using interactive three-dimensional image post-processing software. The course consisted of seven seminars held on a weekly basis. The 25 participating fourth- and fifth-year medical students learnt to systematically analyse cross-sectional imaging data and correlated the two-dimensional images with three-dimensional reconstructions. They were instructed by experienced radiologists and collegiate tutors. The improvement in radiological knowledge, diagnostic skills and visual-spatial ability was assessed immediately before and after the course by multiple-choice tests comprising 64 questions each. Wilcoxon signed rank test for paired samples was applied. Results: The total number of correctly answered questions improved from 36.9 ± 4.8 to 49.5 ± 5.4 (p < 0.001) which corresponded to a mean improvement of 12.6 (95% confidence interval 9.9–15.3) or 19.8%. Radiological knowledge improved by 36.0% (p < 0.001), diagnostic skills for cross-sectional imaging by 38.7% (p < 0.001), diagnostic skills for other imaging modalities – which were not included in the course – by 14.0% (p = 0.001), and visual-spatial ability by 11.3% (p < 0.001). Conclusion: The integration of interactive three-dimensional image post-processing software into undergraduate radiology education effectively improves radiological reasoning, diagnostic skills and visual-spatial ability, and thereby

The purpose of this study was to determine the factors that influence and contribute to patient exposure in radiologic procedures performed in the offices of 132 staff members within the dental department of a teaching hospital. A questionnaire was prepared in which data were requested on brands of film used, type of x-ray unit used, processing, and use of leaded apron, cervical shield, and film holder. Offices were also visited to evaluate performance of existing dental x-ray equipment. Both the Dental Radiographic Normalizing and Monitoring Device and the Dental Quality Control Test Tool were evaluated. The average exposure was equivalent to the class D film (220 mR), but only 13% of those surveyed used the faster class E film, which would reduce patient exposure in half. The survey indicates that dentists are not using the newer low-exposure class E film in their practices

7,176 official quality control reports on dental diagnostic radiology were studied, relating to dental clinics located in 37 Spanish provinces covering 16 different autonomous Regions. The reports were issued as a result of the entry into force of Royal Decree 2071/1995 on quality control in General Diagnostic Radiology facilities, this Royal Decree was replaced by R. D. 1976/1999. The reports were writen by the UTPR (Technical Unit of Radiological Protection) Agsigma S. A. L., a company approved by the Nuclear Safety Council, and they correspond with the official reports issued during 1996-2001. This meants that a 5-year period has been monitored in order to observe the impacts of the establlishment of this legislation on quality control in intraoral dental diagnostic radiology facilities. The results show that 72.79% of the reports checked in 2001 would comply with the European Union's official recommendation (70 kVp, 8 mA> 1.5 mm of Al and 20 cm collimator length). Significant alterations have detected in a third (30.59%) of the radiological equipment. (Author) 36 refs

it is notorious that one of the main causes of radiological accidents is the lack of knowledge of radiological protection of workers. In order to meet the needs of professionals in acquiring a solid base in radiological protection and safety, was created in 2013, by the Casa Branca School / SP and technically supported by the company MAXIM Cursos, the 'Post-Graduation Course Lato Sensu de Radiological Protection in Medical, Industrial and Nuclear Applications', which offers a broad improvement in radiation protection. The course of 380 hours and duration of 18 months is divided into 13 modules, including theoretical classes, in person and online using the virtual classroom and practical training in radiation protection in general. In the end students should present a monograph, guided by a course teacher and reviewed by an Examining Bank. Five classes have been formed in these four years, totaling 92 students. In all, 51 monographs have been defended on topics of technical and scientific interest. For this, the Faculty consists of 25 professors, being 9 Doctors, 13 Masters and 3 Specialists in Radiological Protection

To minimise the radiation dermatitis related to interventional radiology (IR), rapid and accurate dose estimation has been sought for all procedures. We propose a technique for estimating the patient skin dose rapidly and accurately using Monte Carlo (MC) simulation with a graphical processing unit (GPU, GTX 1080; Nvidia Corp.). The skin dose distribution is simulated based on an individual patient's computed tomography (CT) dataset for fluoroscopic conditions after the CT dataset has been segmented into air, water and bone based on pixel values. The skin is assumed to be one layer at the outer surface of the body. Fluoroscopic conditions are obtained from a log file of a fluoroscopic examination. Estimating the absorbed skin dose distribution requires calibration of the dose simulated by our system. For this purpose, a linear function was used to approximate the relation between the simulated dose and the measured dose using radiophotoluminescence (RPL) glass dosimeters in a water-equivalent phantom. Differences of maximum skin dose between our system and the Particle and Heavy Ion Transport code System (PHITS) were as high as 6.1%. The relative statistical error (2 σ) for the simulated dose obtained using our system was ≤3.5%. Using a GPU, the simulation on the chest CT dataset aiming at the heart was within 3.49 s on average: the GPU is 122 times faster than a CPU (Core i7-7700K; Intel Corp.). Our system (using the GPU, the log file, and the CT dataset) estimated the skin dose more rapidly and more accurately than conventional methods.

A sparse file is stored without holes by storing a data portion of the sparse file using a parallel log-structured file system; and generating an index entry for the data portion, the index entry comprising a logical offset, physical offset and length of the data portion. The holes can be restored to the sparse file upon a reading of the sparse file. The data portion can be stored at a logical end of the sparse file. Additional storage efficiency can optionally be achieved by (i) detecting a write pattern for a plurality of the data portions and generating a single patterned index entry for the plurality of the patterned data portions; and/or (ii) storing the patterned index entries for a plurality of the sparse files in a single directory, wherein each entry in the single directory comprises an identifier of a corresponding sparse file.

Computer forensic analyst is a person in charge of investigation and evidence tracking. In certain cases, the file needed to be presented as digital evidence was deleted. It is difficult to reconstruct the file, because it often lost its header and cannot be identified while being restored. Therefore, a method is required for identifying the file type of file fragments. In this research, we propose Longest Common Subsequences that consists of three steps, namely training, testing and validation, to identify the file type from file fragments. From all testing results we can conlude that our proposed method works well and achieves 92.91% of accuracy to identify the file type of file fragment for three data types.

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
