  • Before a subspecialty registration is submitted, any outstanding ABR fees must be paid in full.

Board Eligibility

Diplomates who successfully completed their training before 2019 have until December 31, 2024 to obtain IR/DR certification. Those who complete their training in 2019 or 2020 have six full calendar years from the completion of training to obtain IR/DR certification.

Recognition and MOC

Recognition of Successful Diplomates

Successful ABR candidates are awarded a continuous ABR specialty certificate in interventional radiology/diagnostic radiology (IR/DR). When the IR/DR certification is issued, the diplomate’s diagnostic radiology certificate will no longer be visible on the ABR website. ABMS CertiFACTS will show the entire certification history, so credentialers will see that the diplomate’s diagnostic radiology certificate was “converted”. Please see the IR/DR Certificate Conversion FAQs for more information.

Maintenance of Certification

Continuous certification in interventional radiology/diagnostic radiology is contingent upon meeting the requirements of the ABR’s Maintenance of Certification (MOC) program. For MOC program details, please see the interventional radiology MOC page.
