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

An 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.

The 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.

Only 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.

Only 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.
