About this exam

The American Board of Physician Specialties (ABPS) offers board certification in diagnostic radiology through its certifying body, the Board of Certification in Radiology. The credential is intended for physicians who have completed accredited radiology training and want board certification through the ABPS pathway rather than through the ABR. Certification is a demonstration of broadly based competence across the full scope of diagnostic imaging, and maintenance of certification is expected over time. The examination is computer-based and multiple choice, and it samples the entire discipline rather than concentrating on a single subspecialty: thoracic, abdominal, genitourinary, musculoskeletal, neurologic, breast, cardiovascular, pediatric, nuclear, ultrasound and obstetric/gynecologic, interventional, and physics and safety content all appear. Preparation should be built around a general diagnostic radiology curriculum, not a single textbook. Work through case-based material in every organ system, review physics and radiation safety deliberately because those questions are easy to neglect, and practice interpreting images described in text rather than relying on pattern recognition alone. Track your weak domains with self-testing and revisit them on a spaced schedule in the final weeks. Exam logistics, including the current question count, appointment length, fee, and passing standard, are published by ABPS and should be confirmed directly on its website before you schedule.

What you'll study

Common questions

About ABPS Diagnostic Radiology preparation

Who is eligible to sit for the ABPS diagnostic radiology exam?

Eligibility generally requires completion of an accredited diagnostic radiology residency and an unrestricted medical license, with additional documentation submitted to ABPS. Requirements can change, so verify the current eligibility criteria and required paperwork directly with the board before applying.

What is the exam format?

It is a computer-based, multiple-choice examination covering the full breadth of diagnostic radiology, including subspecialty organ systems plus physics, radiation safety, and quality assurance. Expect image-based and case-based stems. The board publishes the current structure and any section breakdown on its website.

How long is the exam and how many questions does it have?

ABPS publishes the current question count and appointment length for each administration. These figures are updated periodically, so check the official ABPS examination page rather than relying on secondhand reports. Plan for a full-day commitment and confirm your allotted time when you receive scheduling instructions.

How hard is the exam?

It is a general certifying examination, so difficulty comes from breadth rather than from obscure trivia. Candidates who trained in a broad program and who review every organ system, including physics and safety, generally find it manageable. The common stumble is deep subspecialty study at the expense of general coverage.

What if I fail? Can I retake it?

Retake policies, waiting periods, and any limits on attempts are set by ABPS and are not fixed across administrations. Review the current retake policy on the board's website before you apply, and ask the board directly if your situation involves a prior unsuccessful attempt.

What score do I need to pass?

The passing standard is established by ABPS and is not something to estimate from forum posts. The board publishes its current passing score or criterion-referenced standard in its candidate materials. Confirm the exact requirement with ABPS before your exam date.

In what order should I study?

Start with the highest-weight general domains and your own weakest areas, then cycle through everything on a spaced schedule. Reserve dedicated time for physics, radiation safety, and quality assurance, which are frequently underprepared. Finish with timed mixed-topic practice so you can rehearse switching between organ systems under pressure.

What are the most common reasons candidates do poorly?

Neglecting physics and safety, over-studying one subspecialty, and never practicing under time constraints are the usual culprits. Another is reading without self-testing, which produces familiarity rather than recall. Build in question practice from the start and review every miss by topic.

How much does the exam cost?

Fees are set by ABPS and vary by application type and timing. The board publishes the current fee schedule on its website. Check there for the exact amount, deadlines, and any additional charges before submitting your application.
