As candidates progress through their residency and after completion of training, they will take two exams to gain initial certification in diagnostic radiology: the Core Exam and the Certifying Exam.
The Core Exam
, offered after 36 months of residency training, is image rich and computer based; it covers 18 subspecialty and modality categories. Candidates must pass overall and in physics to receive a passing result.
The Certifying Exam
, given approximately 15 months after completion of diagnostic residency training, is also computer based and image rich, and it includes four modules. Three modules are clinical practice areas and may be chosen by the examinee to fit his or her interests, experience, and training. The other module, Essentials of Diagnostic Radiology, is taken by all examinees.
Content for the Radioisotope Safety Exam (RISE)
is integrated into the Core
exams. After a candidate passes the Certifying Exam, the RISE will be scored. Candidates who have submitted the appropriate documentation and receive a passing score on the RISE content will be given the Authorized User-Eligible (AU-E) designation on their certificate. The RISE result will not affect the pass results for either the Core or Certifying exam.
