ABR DR Core

It is an examination in the ABR's Diagnostic Radiology certification pathway, listed by the ABR under its Get Certified section for Diagnostic Radiology. The ABR states its mission is to certify that diplomates demonstrate the requisite knowledge, skill, and understanding of their disciplines to the benefit of patients. Verify current exam details directly with the ABR.

It is intended for physicians progressing through the ABR's Diagnostic Radiology initial certification pathway. Eligibility rules, including training requirements and application deadlines, are set by the ABR and are not reproduced here because the ABR's Core Exam page could not be retrieved. Check the ABR's Get Certified and Exam Dates and Information pages before applying.

The ABR organizes its certification content under Diagnostic Radiology, and this study profile divides preparation into physics, radiobiology, noninterpretive skills, and diagnostic radiology across all organ systems. Those domain weightings are estimates used for study planning, not official ABR percentages. Consult the ABR for the authoritative content outline.

We do not report an item count or time limit, because the ABR's Core Exam page returned a 404 error when retrieved and the source text contains no such figures. Any number you see elsewhere may be outdated. Confirm the current format, timing, and scheduling windows with the ABR before you build a test-day plan.

The passing standard is not stated in the available source material, so it is not listed here. The ABR sets and periodically revises its standards, and third-party figures are frequently stale. Review the ABR's own policies and exam information pages for the current standard rather than relying on remembered or forum-reported cutoffs.

Retake rules, including any waiting periods or limits on attempts, are governed by ABR policy and are not described in the source text available here. Because the dedicated Core Exam page could not be retrieved, confirm the retake policy directly with the ABR through its Policies and Agreements or Help and Support pages.

It is a broad, high-stakes certifying exam, so difficulty is real. Common failure modes are uneven coverage: over-studying one organ system while neglecting physics or noninterpretive skills, reading without image-based practice, and skipping timed practice under exam conditions. Build a schedule that touches every domain repeatedly rather than cramming one at the end.

Start with physics and radiobiology early, since they reward spaced repetition and are easy to postpone indefinitely. Run organ-system review in parallel throughout, and layer in noninterpretive skills and timed mixed-question blocks in the final months. Interleave topics rather than blocking one subject for weeks; retrieval practice beats rereading.

The ABR homepage carries an October 2026 Board of Governors item titled "New DR Oral Exam Will Improve Assessment of Candidate Knowledge and Skills." The source gives no effective date, format, or specifications. Treat it as an announced development only, and confirm timing and requirements with the ABR before planning.
