16-Month Pathway to Dual Certification

in Diagnostic Radiology and Nuclear Radiology

The ABR has approved conditions and requirements for a pathway leading to eligibility for both primary certification in diagnostic radiology and subspecialty certification in nuclear radiology.
A resident who has 16 months of experience in nuclear radiology or nuclear medicine during the 48-month diagnostic radiology residency may qualify for the ABR’s subspecialty certificate in nuclear radiology.
To qualify for this pathway to subspecialty certification, all 16 months of experience must be in an ACGME-accredited diagnostic radiology program; there is no requirement for a nuclear medicine residency or nuclear radiology fellowship program.
The 16 months may be completed at any time during diagnostic radiology residency training; there is no requirement for consecutive months.
Up to two months of experience in nuclear radiology or nuclear medicine during the PGY1 clinical year may be counted if completed at an institution with an ACGME-accredited diagnostic radiology residency program.
Four months are required of every resident in diagnostic radiology, and count toward the 16-month pathway.
At the discretion of the diagnostic radiology program director, up to four months of training may be in a nuclear radiology-related, nuclear medicine-related, and/or molecular imaging-related field (e.g., head and neck, neuroradiology, MRI, PET/MR, radioembolization, or interventional radiology.)
