Initial Certification


Initial certification information is for candidates who are not yet certified in the primary specialties of diagnostic radiology, interventional radiology, radiation oncology, and medical physics; any of the subspecialties of diagnostic radiology (neuroradiology, nuclear radiology, pediatric radiology, and vascular and interventional radiology); and hospice and palliative medicine, which is a subspecialty of both diagnostic radiology and radiation oncology.

The ABR conducts initial qualifying and certifying examinations to ascertain the qualification of those who have completed training in the specialties listed above. A board-certified diagnostic radiologist, interventional radiologist, radiation oncologist, or medical physicist is one who has demonstrated the requisite standard of knowledge, skill, and understanding essential to the practice of one of these specialties.


Board certification serves as an important marker for a high standard of care. It reflects the critical core values of compassion, patient-centeredness, and a passion for education. Patients, physicians, healthcare providers, insurers, and quality organizations look for board certification as the best measure of a physician’s knowledge, experience, and skills to provide quality health care within a given specialty.

Diagnostic Radiology (DR) is the specialty of clinical medicine that encompasses a variety of diagnostic and image-guided therapeutic techniques, including all aspects of radiological diagnosis, nuclear radiology, diagnostic ultrasound, magnetic resonance imaging, computed tomography, interventional procedures, and the use of other forms of radiant energy. 

Interventional Radiology (IR) is the specialty of clinical medicine that uses minimally invasive image-guided procedures to diagnose and treat diseases. The pathway to IR/DR certification will be available to those who have finished an interventional radiology residency. Please see the interventional radiology page for more information.

Radiation Oncology (RO) is the specialty of clinical medicine concerned with the prevention, cause, and treatment of cancer and selected benign conditions, with the use of ionizing radiation as a treatment tool.

Medical Physics (MP) is the specialty of physics that includes therapeutic medical physics, diagnostic medical physics, and nuclear medical physics.

A certificate granted by this Board does not of itself confer, or purport to confer, any degree or legal qualifications, privileges, or license to practice in the certified discipline.
