The utilisation of radiology for the teaching of anatomy in Canadian medical schools

Objective

To determine the utilisation of diagnostic imaging (radiology) as a department and/or imaging medium in the teaching of anatomy at the Canadian undergraduate medical education level.

Methods

The study objectives were achieved through the use of a questionnaire and a literature review. The anatomy department head at each English-based Canadian Medical School was contacted, and the individual most responsible for anatomy teaching in the medical school curriculum was identified. This individual was subsequently asked to complete a questionnaire that evaluated the involvement of radiology for anatomy teaching in their curriculum.

Results

The use and integration of radiology is a common practice in the teaching of anatomy in Canadian undergraduate medicine. Although the methods and extent of its use varied among institutions, every English-based Canadian medical school, except one, was using diagnostic imaging material in their instruction of anatomy. Furthermore, half of the institutions had a radiologist as a faculty member of their anatomy department to help teach and to use imaging to its full potential.

Discussion

This audit of anatomy departments suggests that diagnostic imaging has an important role to play in anatomy teaching in Canadian English-speaking medical schools.     

Gross anatomy instruction with diagnostic images

A new module of instruction for diagnostic imaging with emphasis on cross-sectional anatomy was developed within the existing course of gross anatomy for freshmen medical students. Two lectures introduced radiation protection, radiology history, and the basic principles of computed tomography, magnetic resonance imaging, ultrasound, and radiograph image production. Six radiographic anatomy correlation sessions allowed student-teacher interaction while studying viewbox images in a "hands on" fashion. Relevant exhibits complemented cadaver dissection. Testing established that significant improvement occurred in the students' ability to identify anatomic structures on diagnostic images.     

Teaching methods in anatomy courses in North American medical schools the role of radiology

RATIONALE AND OBJECTIVES: We sought to determine the current and anticipated future status of anatomy education in medical schools in North America, with particular emphasis on the role of radiologists and imaging in the curriculum. MATERIALS AND METHODS: A Web-based survey was sent to all schools identified using the AAMC Web site to find e-mail addresses for deans and course directors. RESULTS: Responses were obtained from approximately 50% of schools. Most courses are taught over a semester, and most are directed by anatomists. Only one is directed by a radiologist. Dissection is still the major teaching method, with radiologic anatomy averaging about 5% of total teaching time. Most directors anticipate a decrease in teaching time over the next 5 years and an increase in use of digital methods and teaching of radiologic anatomy. CONCLUSION: The role of radiologists will probably increase in future teaching of anatomy.     

Medical Student Performance After a Vertically Integrated Radiology Clerkship

PurposeProper selection of imaging examinations and basic image interpretation skills are essential for all physicians, yet only approximately 25% of US medical schools require clerkships in radiology. Although there is limited time in most medical school curricula to allow the addition of a required radiology clerkship, the authors developed one that is vertically integrated over a two-year period. This clerkship includes one week of contact with radiologists distributed over the M2 and M3 years, podcasts, online modules, required readings, and presentations. A standard national examination is administered at the end of the clerkship period. This clerkship was designed to address the educational needs of students while occupying minimal time in the curriculum. The purpose of this study was to determine if students completing this clerkship perform as well on a national radiology examination as students from other medical schools, regardless of their curricula.MethodsAt the end of the M3 year, these students take a computer-based radiology examination developed by the Alliance of Medical Student Educators in Radiology and used by students at multiple medical schools nationally. The mean and median scores of these students were compared with those of students at these other institutions.ResultsThe mean and median scores of the students were 74% and 74% (standard deviation, 7.5%) compared with 74% and 50% (standard deviation, 8.4%) at other institutions.ConclusionsStudents completing this vertically integrated radiology clerkship had test scores comparable with those of students at other medical schools.     

Implementation of a new undergraduate radiology curriculum: experience at the University of British Columbia.

OBJECTIVES: The purpose of this study was to review and revise the undergraduate radiology curriculum at the University of British Columbia to improve radiology education to medical students and to meet the needs of a medical program with province-wide distribution. METHODS: We identified the radiology content of the curriculum from the Curriculum Management and Information Tool online database, from personal interviews with curriculum heads, and from published information. Undergraduates' and recent graduates' opinions were solicited by means of surveys. Information on radiology curricula at medical schools across Canada was gathered from email surveys and personal contacts with members of the Canadian Heads of Academic Radiology (CHAR). RESULTS: Review of our curriculum indicated that lack of a unified syllabus resulted in redundant content, gaps in knowledge, and lack of continuity in the curriculum. Results from the survey of programs across Canada indicated that most schools also lacked a formal radiology curriculum for medical students. By adapting the guidelines from the Association of Medical Student Education in Radiology, we revised our undergraduate radiology curriculum to emphasize integration and self-learning. The modified curriculum includes a combination of instructional technology, focused lectures in preclinical years, and in-context seminars in clerkship rotations. CONCLUSION: Most medical schools in Canada do not have a formal radiology curriculum for medical students. A structured curriculum is required to improve the quality of radiology teaching for medical students.     

Radiologists as clinical tutors in a problem-based medical school curriculum.

RATIONALE AND OBJECTIVES: The authors sought to evaluate the experience of radiologists teaching in a problem-based pre-clinical medical school curriculum. MATERIALS AND METHODS: The undergraduate medical school curriculum at Wake Forest University includes 2 problem-based preclinical years that integrate basic and clinical sciences. Sixteen radiology fellows served as general clinical tutors for 5-9 weeks, each guiding the work of six 2nd-year students, often in tandem with a basic science tutor. On completion of the tutoring. the radiologists and the students were surveyed by means of a questionnaire. A follow-up group interview was conducted with the radiologists. RESULTS: The response rate to the questionnaire was 81% for the radiologists and 47% for the students. On average, radiologists spent 6.1 hours weekly on preparation and tutoring and 3.5 hours in total on administration and grading. All radiologists thought tutoring was rewarding, but seven of the 13 respondents (54%) disliked assigning grades. Radiologists spent less time teaching radiology residents and performing research, but few thought their clinical work was adversely affected. Nearly half of the radiologist-tutors thought that the preliminary orientation and training provided to them by the medical school was not adequate, and nearly all of them thought that they could have been better prepared. All of the medical students improved their perceptions of radiologists after having had a radiologist as a tutor, and most thought that the radiologist-tutors performed as well as or better than tutors from other disciplines. CONCLUSION: Radiologists can be successful as general tutors in a problem-based medical school curriculum. benefiting both radiologists and students. Better orientation and training by the medical school would improve the program.     

Effectiveness of teaching radiologic image interpretation in gross anatomy. A long-term follow-up.

This prospective study was designed to gauge the effectiveness of teaching radiologic interpretation during a gross anatomy course for first-year medical students by measuring short- and long-term ability to identify normal anatomic structures on radiologic diagnostic images. The evaluation required students to identify normal anatomic structures on radiographs, computed tomographs, ultrasonograms, and magnetic resonance images (MRIs). The assessments were made before (pre-test) and during (post-test) the experimental radiology portion of the gross anatomy course. The students were then retested 14 to 17 months later (long term). The pre-test correct response rate of 17% improved to 88% on the post-tests. After 14 to 17 months, the students had a 74% correct response rate on the same images and anatomic structures. This high level of long-term retention documents the effectiveness of integrating diagnostic radiologic imaging into normal gross anatomy instruction.     

Multidisciplinary Approach in Teaching Diagnostic Radiology to Medical Students: The Development,Implementation, and Evaluation of a Virtual Educational Model

PurposeThe aim of this study was to develop, implement, and evaluate the effectiveness of an online multidisciplinary approach for teaching diagnostic radiology to medical students.MethodsAn online 10-session case-based learning course was designed and taught by a multidisciplinary team of radiologists, surgeons, and internists. Session topics included common clinical case scenarios for different systems and were hosted on a videoconferencing platform. Students from six medical schools across Texas enrolled in the course. The effectiveness of each session was evaluated using a pretest-posttest design. Students completed a final survey after the course to evaluate their experience.ResultsAn average of 108 attended the live sessions, with attendance peaking at 220. On average, 75 students completed both the pretest and posttest of each session. Posttest scores were an average of 46% higher than pretest scores. A total of 109 students completed the final survey; more than 90% of participants agreed that the program was relevant, that its multidisciplinary approach was valuable, and that it increased their knowledge of imaging as a diagnostic tool. Seventy-four percent said that the program increased their interest in radiology. Almost all participants said that the topics presented were thought to be “excellent and clinically important to learn” by most of the students (70%). Participants reported increased confidence in basic radiology skills after completion of the program.ConclusionsAn online multidisciplinary approach can be feasibly implemented to address the radiology education needs of a large number of medical students across a group of medical schools.     

The State of Radiologic Teaching Practice in Preclinical Medical Education: Survey of American Medical,Osteopathic, and Podiatric Schools

PurposeThis study describes the state of preclinical radiology curricula in North American allopathic, osteopathic, and podiatric medical schools.MethodsAn 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.ResultsOf 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.ConclusionsThis 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.     

Integrated teaching of anatomy and radiology using three-dimensional image post-processing

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.     

Surveying Fourth-Year Medical Students Regarding the Choice of Diagnostic Radiology as a Specialty

PurposeThe aim of this study was to survey fourth-year medical students, both those choosing and those not choosing diagnostic radiology as their specialty, regarding factors influencing their choice of specialty and their perceptions of radiology.MethodsA voluntary anonymous online survey hyperlink was sent to 141 US medical schools for distribution to fourth-year students. Topics included demographics, radiology education, specialty choice and influencing factors, and opinions of radiology.ResultsA representative sampling (7%) of 2015 fourth-year medical students (n = 1,219; 51% men, 49% women) participated: 7% were applying in radiology and 93% were not. For respondents applying in radiology, the most important factor was intellectual challenge. For respondents applying in nonradiology specialties, degree of patient contact was the most important factor in the decision not to choose radiology; job market was not listed as a top-three factor. Women were less likely than men to apply in radiology (P < .001), with radiology selected by 11.8% of men (56 of 476) and only 2.8% of women (13 of 459). Respondents self-identifying as Asian had a significantly higher (P = .015) likelihood of selecting radiology (19 of 156 [12.2%]) than all other races combined (44 of 723 [6.1%]). Respondents at medical schools with required dedicated medical imaging rotations were more likely to choose radiology as a specialty, but most schools still do not require the clerkship (82%).ConclusionsThe reasons fourth-year medical students choose, or do not choose, diagnostic radiology as a specialty are multifactorial, but noncontrollable factors, such as the job market, proved less compelling than controllable factors, such as taking a radiology rotation.     

The senior radiology clerkship. Disparate goals of students and faculty

A survey of medical students taking our radiology elective over the past five years revealed that 51% were chiefly interested in learning "to read x-rays." Other motivations for taking the elective, such as learning "radiographic workups" were relatively low-priority goals. On the other hand, a survey of our staff revealed a low priority placed on teaching medical students to interpret radiographic images and a high value placed on imparting an understanding of the role of radiology in clinical diagnosis and management. This disparity between the goals of the students and teachers delineates one of the major challenges in designing a radiology curriculum for medical schools.     

COMPARE radiology: creating an interactive Web-based training program for radiology with multimedia authoring software

RATIONALE AND OBJECTIVES: Computer-based training has two primary benefits: Content can be presented interactively, and students can choose the time, place, and pace of learning. As a subject of medical education, radiology lends itself particularly well to computer-based training because of its highly visual content. To improve the efficiency of radiology training at their institution, the authors decided to create an interactive Web-based training site. MATERIALS AND METHODS: Working with a group of medical students knowledgeable in multimedia authoring, the authors used authoring software to create "COMPARE Radiology," an interactive training program that follows the modality-based structure of the undergraduate curriculum for radiology at the University of Erlangen-Nuremberg, Erlangen, Germany, and at medical schools worldwide. RESULTS: The Web-based program offers cases and exercises in radiographic anatomy at different selectable levels of difficulty, allowing users to test and build their knowledge of radiology. Pathologic images are initially presented without any further information. Additional information (patient history, laboratory results, reports from other imaging studies, and normal images for comparison) can be retrieved selectively and successively. Further information regarding the diagnosis and pathologic findings can be found by following links to external Web sites. The COMPARE Radiology program content is extended and updated regularly. The program is subject to internal peer review and can be evaluated by the user online. CONCLUSION: The authors' experience shows that a highly interactive Web-based training program for radiology, tailored to the requirements of the target group, can be developed economically by a team of medical students using an advanced storing system, with the guidance of a radiologist and without the help of professionally trained computer experts.     

Organ system radiology. Instruction of sophomore medical students

During a six-year period we have evolved a method of teaching organ system radiology to sophomore medical students. This involves didactic and clinical sessions with small group discussions and activities central to the program. The course is designed to present a bridging course between the basic medical sciences and the clinical sciences and to better prepare students for their patient care responsibilities.     

Radiology Clerkship Requirements in Canada and the United States: Current State and Impact on Residency Application

PurposeAn unmet need for radiology education exists even in this era of medical school curricular renewal. The authors examined the radiology clerkship requirements in Canadian and US medical schools to interpret radiology residency applicant trends.MethodsThe curricula of Canadian and US medical schools were reviewed for radiology rotation requirements. The radiology residency applicant trends for 2010 to 2019 were analyzed using linear regression. The number of radiology electives taken by matched radiology applicants was examined. Regression analysis was performed to assess the impact of radiology rotation requirements on residency application.ResultsOnly 1 of 17 Canadian medical schools required a radiology rotation despite major curricular renewal at the majority of medical schools. Approximately 20% of US medical schools required radiology rotations, without a significant change from 2011 to 2018, whereas the duration of required radiology rotations increased significantly. The numbers of total and first-choice radiology applicants showed significant decreases from 2010 to 2019 in Canada but not in the United States. Nearly all matched radiology applicants took electives in radiology, the majority of whom took three or more electives. Both the presence and duration of radiology rotation requirements showed significant, positive relationships with the number of radiology applicants.ConclusionsOnly a minority of medical schools in North America have radiology clerkship requirements, both the presence and duration of which significantly affect students’ choice of radiology as a career. Radiology clerkship requirements can be a solution to meet the expanding demand for diagnostic imaging in modern medicine.     

Tomorrow’s radiologist: what future?

Today's radiology is experiencing two major trends, one negative and one positive. The first is the so-called turf war, in other words, the progressive invasion of the imaging domain by other specialists such as cardiologists, urologists, gastroenterologists, gynaecologists etc. who are taking over various techniques from ultrasonography (US) to computed tomography (CT) to magnetic resonance imaging (MRI). In this process, they are aided by new technologies such as picture archiving and communication systems (PACS) and computed-aided diagnosis CAD and by radiology technologists who collaborate with them, replacing radiologists. The positive aspect is the outstanding technological evolution: the advent of molecular imaging, optical imaging, nanotechnologies, teleradiology and percutaneous gene therapy. While dramatically expanding the diagnostic possibilities down to the subcellular level, these techniques demand new forms of training in radiology and interdisciplinary cooperation. Tomorrow's radiologist will need to acquire appropriate clinical knowledge, restore contact with the patient to take on a prominent role in the diagnostic process, learn the basic sciences, foster a multidisciplinary approach and finally be able to use the Internet for learning and continuing education. Tomorrow's radiologists will survive if they learn to reinvent themselves.     

Peace through health II: a framework for medical student education

The world's first university course in Peace through Health (PtH) recently finished at McMaster University, Hamilton, Canada. Medical students and academic staff in Canada and Europe have expressed interest in developing this course for other medical schools. Seven medical students were selected to do an unofficial 'audit' in return for 'in kind' work, developing the course materials for the web and adaptation to the medical curriculum. This article sets out the goals and structure of the course as a guide for similar teaching models.     

Howard University program for radiotherapeutic technology.

The Howard University program for radiotherapeutic technology provides for a career ladder with steps of two years. After the first two years everyone must take and pass examination in radiotherapeutic technology given by The American Registry of Radiologic Technologists. The candidate then can proceed with two years of university courses to a Bachelor of Science degree. Depending upon his interest, he can emphasize business, education, or science. The latter would qualify him for application medical school. The core of the curriculum for the first two years consists of clinical work in the radiotherapy department every morning and of two integrated multidisciplinary courses in the afternoon, namely, life sciences (anatomy, physiology, pathology and oncology) and natural sciences (mathematics, physics, radiation physics and treatment planning).     

Resident education in the radiological sciences: what now?

OBJECTIVE: With the dizzying changes in the rapidly evolving profession of radiology, the structure of resident education in the associated sciences of imaging, physics, radiobiology, and radiation effects must be reevaluated continually. What roles do these basic radiologic sciences play in bolstering the neophyte radiologist on a career of patient care? How should we define the spectrum of material that should be learned? How should that spectrum be taught? Who decides these things? With the impending changes in the radiology board certification process, questions have been raised as to how these changes will affect education in a residency program. Should the basic science curriculum be enhanced or scaled back? With the emphasis on practical applied physics, what is considered old school and what is new school material? CONCLUSION: This article describes one approach adopted by a large residency program to address these issues.     

Curriculum in radiology for residents: what, why, how, when, and where

Developing a curriculum in chest radiology should follow the same general principles that are used when developing a curriculum in any subspecialty area of radiology. A curriculum is more than a "list of topics" with which a resident should be familiar after 4 years of training. It includes objectives and goals, content, faculty, methods, and evaluation. Numerous resources are available for those who are charged with developing a curriculum in chest radiology. In addition to faculty members in the department, whose input during development can ensure successful implementation of the curriculum, organizations (i.e., ACR, APDR, STR) already have begun to develop "model" curricula. Attending the annual meeting of the Association of American Medical Colleges is a way to meet and hear from professionals who develop and oversee curriculum development at their medical schools, and another important resource available at some medical schools is the Office of Medical Education. The faculty within such offices are uniquely qualified to assist with curriculum and faculty development, especially for those areas in which radiology faculty traditionally are less experienced, such as development of valid and reliable assessment forms and construction of behaviorally based objectives.
