PURPOSE:It can be difficult particularly for internal medicine residents and less experienced physicians who are not specialized in chest radiology to differentiate between physiological thoracic structures and normal variants from pathological findings on plain film and CT. We designed an interactive, step-by-step tutorial in order to teach residents and refresh information about benign and malignant findings in chest imaging. The educational value of this chest tutorial was assessed using a pre-tutorial and post-tutorial questioner.
METHODS:This online chest tutorial (“chestradiology.net”) consists of over 150 pages and over 80 images covering plain film and computed tomography. Chapters offer learning material about techniques, standard exams, projections, airways, lung parenchyma, heart and vessels, mediastinum, diaphragm, pleura, pathology. Pre- and post tests evaluate the educational experience. 27 residents and medical students were asked to answer 10 different questions on the topic covered in the website. After a one hour tutorial the same questions were given to them in order to evaluate the learning progress.
RESULTS:Initially most residents and students were able to answer only 2–3 basic questions regarding chest anatomy (20%–30%). Respectively 4 residents answered correct 1 questions; 4 residents answered correct 1 questions 4 residents answered correct 1 questions 4 residents answered correct 1 questions4 residents answered correct 1 questions. After one hour tutorial that briefly presented the radiology web site the same residents and medical students were asked to answer the same questions. Most residents answered 6–7 questions 60%–70%.
CONCLUSION:We present an interactive tutorial which serves residents and medical students as a comprehensive learning tool as well as a quick reference to get familiar with physiologic and pathologic findings in chest imaging. Free online access makes it constantly and quickly available and interactivity helps to accommodate the user’s needs to enhance the learning experience as demonstrated in our study.
CLINICAL IMPLICATIONS:Our study demonstrates that the interactive tutorial is a valuable educational method, teaching medical students and residents to differentiate between physiological and pathological findings on chest x-ray and CT.
