How training is structured
The Royal College sets out the training for Nuclear Medicine in the blocks below. An internationally trained specialist is assessed on whether their own training and practice record is comparable in structure and content.
Pathway 1 — 1. PGY1 year
One (1) year
1.1 Minimum three (3) months Internal Medicine and/or its subspecialties; 1.2 any combination of surgery (general or other primary surgical specialty), pediatrics (general or subspecialties), radiation oncology, or pathology, maximum three (3) months in any one area; 1.3 maximum two (2) months Diagnostic Radiology or Nuclear Medicine.
Pathway 1 — 2. Clinical Cardiology
Minimum one (1), maximum three (3) months
Clinical Cardiology (may be completed as part of PGY1, section 1).
Pathway 1 — 3. Nuclear Medicine training
Three (3) years
Diagnostic and therapeutic use of open source radioactive materials and related technologies at all ages and all body systems, progressing from introductory to independent practice level. Comprising sections 3.1 general Nuclear Medicine, 3.2 nuclear cardiology, 3.3 positron emission tomography (PET, a functional imaging scan)/computed tomography (CT), 3.4 hybrid imaging (single photon emission computed tomography (SPECT)/CT and PET/CT), 3.5 pediatric nuclear medicine, and 3.6 therapeutic nuclear medicine (see required experiences).
Pathway 1 — 4. Cross-sectional imaging
Six (6) months
Cross-sectional imaging in Diagnostic Radiology relevant to Nuclear Medicine, including head, chest, and body computed tomography (CT) and magnetic resonance imaging (MRI).
Pathway 1 — 5. Flexible period
Up to six (6) months
Selected from sections 5.1 to 5.5 (see flexible options).
Pathway 2 — 1. PGY1 year
One (1) year
Same requirements as Pathway 1 section 1 (1.1 to 1.3).
Pathway 2 — 2. Diagnostic Radiology
Three (3) years
Training in Diagnostic Radiology.
Pathway 2 — 3. Nuclear Medicine training
Two (2) years
Same content areas (3.1 to 3.6) as Pathway 1 section 3.
Pathway 2 — 4. Clinical Cardiology
Minimum one (1), maximum three (3) months
Must be completed within section 1 or section 3.

Common questions
What is the Practice Eligibility Route in Nuclear Medicine?
The Practice Eligibility Route (PER) is the Royal College process by which an internationally trained specialist can be assessed for eligibility to sit the certification examination in Nuclear Medicine without repeating a Canadian residency. The Royal College reads your postgraduate training and practice record against the published Specialty Training Requirements for the discipline.
What training does the Royal College expect in Nuclear Medicine?
The Specialty Training Requirements describe pathway 1: Five (5) years of approved residency training. Pathway 2 (in association with Diagnostic Radiology): a minimum of six (6) years. The full block-by-block structure is set out on this page, taken from the Royal College document for this discipline.
Does meeting the training requirements guarantee eligibility?
No. Eligibility is a committee decision made on your individual file, and other factors are considered. This page reproduces the published requirements so you can see how your own training compares before you apply; it is not an eligibility ruling.
Where do I start?
Read the six steps in the PER guide, then have your training mapped against the Specialty Training Requirements before you pay any fees. The free PDF for this specialty carries the steps, the document checklist, and the Nuclear Medicine requirements in one file.
Not sure the PER is your route?
Some specialists are better served by a provincial practice-ready assessment, and some provinces assess only the disciplines currently on their intake list. The free screener checks your file against every route in about two minutes.
