Frequently Asked Questions
What is the ABPS Diagnostic Radiology (BCDR) Certification Examination?
The ABPS Diagnostic Radiology Certification Examination is administered by the Board of Certification in Diagnostic Radiology (BCDR) under the American Board of Physician Specialties (ABPS). It validates the competencies required for diagnostic radiologists across cardiothoracic, gastrointestinal, genitourinary, breast, musculoskeletal, neuroradiology, pediatric, nuclear medicine/PET, ultrasound, vascular/interventional, and physics/safety domains. ABPS is a non-ABMS multi-specialty certifying body that has provided physician board certification since 1952.
Who is eligible to take the BCDR Diagnostic Radiology exam?
Candidates must hold an MD, DO, or equivalent doctoral medical degree with a valid unrestricted medical license, and have completed an ACGME-accredited (or BCDR-recognized equivalent) diagnostic radiology residency program. Candidates must currently practice in diagnostic radiology and submit letters of reference attesting to clinical competence. Always verify current eligibility requirements on the ABPS BCDR website.
What is the format of the exam?
The BCDR Diagnostic Radiology exam is a computer-based test of single-best-answer multiple-choice questions (approximately 200 items over ~4-5 hours) blueprinted to BCDR's content outline: Cardiothoracic (~13%), Neuroradiology (~12%), GI (~12%), GU (~10%), Breast (~10%), MSK (~10%), Pediatric (~8%), Nuclear/PET (~8%), Ultrasound (~7%), Vascular/IR (~5%), and Physics/Safety/Informatics (~5%). Many items use image-rich vignettes drawn from radiography, CT, MRI, ultrasound, fluoroscopy, mammography, and nuclear medicine.
How much does the 2026 exam cost?
The 2026 BCDR Diagnostic Radiology examination fee is approximately $2,000-$2,500 — always verify the current fee schedule on the ABPS website. Candidates should also budget for ongoing Continuous Certification (CC) fees after passing. Cancellation and refund policies follow the BCDR schedule with decreasing refunds as the exam date approaches.
When is the 2026 exam administered?
BCDR offers the Diagnostic Radiology examination at multiple test administrations each year per the published ABPS/BCDR schedule. Candidates schedule specific appointments after application approval. Exact 2026 dates should be confirmed on the ABPS Diagnostic Radiology page.
How is the exam scored?
BCDR uses criterion-referenced scaled scoring with a passing standard set by subject-matter experts using the modified Angoff method. A candidate's pass/fail result depends on performance relative to the fixed cut-score, not on other candidates. Score reports typically include domain-level feedback so candidates know their strongest and weakest content areas.
What are the highest-yield 2026 topics?
Highest-yield 2026 topics include the ACR Manual on Contrast Media 2024 (eGFR thresholds, premedication for prior reactions, gadolinium classes), USPSTF 2024 breast screening update (biennial age 40-74), FDA Mammography Quality Standards Act dense breast notification effective Sept 2024, ACR BI-RADS 5th edition, Lung-RADS and Fleischner 2017, LI-RADS for HCC, Bosniak 2019 renal cysts, PI-RADS v2.1 prostate, McDonald 2017 MS criteria, ASPECTS for stroke, and theranostics (Lu-177 DOTATATE, Lu-177 PSMA-617). MRI safety zones I-IV and CTDIvol/DLP dose reporting are perennial favorites.
How does ABPS BCDR compare to ABR diagnostic radiology certification?
ABPS BCDR is administered by the American Board of Physician Specialties, a non-ABMS certifying body, while the ABR (American Board of Radiology) is the traditional ABMS pathway with separate Core (PGY-4) and Certifying (15 months post-residency) exams. ABMS recognition is more widely required for hospital privileges and managed care credentialing in some markets, but ABPS BCDR is recognized by many hospitals and provides an alternative pathway for residency-trained diagnostic radiologists. Always verify hospital and payer credentialing requirements before choosing a certification pathway.
How should I study for this exam?
Use a structured 6-12 month plan layered on clinical practice. Map study to the BCDR content outline: begin with physics and safety (CT dose, MRI safety zones, ACR Contrast Manual), then drill body imaging (chest CXR/HRCT, GI/GU, breast BI-RADS), then MSK/neuro/peds, and close with nuclear medicine, ultrasound, and vascular/IR. Use textbooks (Brant & Helms Fundamentals; Mandell Core Radiology; Donnelly Pediatric Imaging), RSNA case collections, ACR Appropriateness Criteria, and high-volume image-rich MCQ practice. Complete 2-3 timed full-length mock exams.
