Novel Teaching Assistant‐Led Approach to the Teaching of Radiographic Imaging in Gross Anatomy

Radiographic imaging is an integral component of Gross Anatomy at Mount Sinai School of Medicine. Alongside a cadaver CT‐based project as an adjunct to gross dissection (Ellozy et al. FASEB J 2009; 23: 480.4), a teaching assistant (TA)‐led imaging module was initiated. Eight second year medical students served as TAs each year. A head TA worked with faculty to compile images from a bank of scanned x‐rays, CT and MRI. Five topics (vertebrae, thorax, abdomen, extremities and head) were integrated into the cadaver dissection schedule. Since the anatomy lab can be a hectic environment for teaching imaging during dissection, TAs took small groups of students in succession out of the lab to run imaging sessions concurrently. Images were projected on large screens in classrooms instead of light boxes on the walls of the lab. TAs guided students through images, often with animation, and used an interactive question and answer format to enhance student participation. Images with blank labels and answer keys were posted on the course website for home review. TAs also gave reviews prior to the midterm and final exams. On the exams, 80–90% of students answered imaging‐based multiple choice questions correctly, reflecting a positive outcome of peer teaching. As medicine becomes increasingly reliant on imaging in clinical practice, early exposure to various radiological modalities is beneficial to future physicians.
