Clinical Training

The first postgraduate year must be accredited clinical training in internal medicine, pediatrics, surgery or surgical specialties, obstetrics and gynecology, neurology, family practice, emergency medicine, transitional year, or any combination of these.
If there is an elective in diagnostic radiology, it must be in a department with an AOA- or ACGME-approved residency program and cannot be longer than two months. No more than a total of three months may be spent in radiation oncology and/or pathology.  

Four-year Plan

The required four years of full-time, continuous residency training or continuous faculty fellowship experience must be completed in one institution with an ACGME- or RCPSC-approved residency program. On a case-by-case basis, credit for research training of up to 12 months may be granted if the research is completed at the same institution as the remaining clinical training.
The four-year experience must include four months of nuclear radiology training.
