Prep for the ABR Core & Certifying exams.
Four domains. Four learning loops. Built around the way residents actually study — with dedicated physics drilling, critical-diagnosis flash reps, and full timed mocks.
Knowledge domains ABR Core Exam blueprint
Diagnostic Physics & Safety
Image production across X-ray, CT, MRI, US. Radiation biology, ALARA, RISC protocols. The domain that rewards dedicated drilling.
Domain 2 · ~70%Clinical Subspecialties
Neuro, Thoracic, MSK, Abdominal/GI/GU, Breast, Cardiac, Nuclear Medicine. The bulk of the exam — organ system by organ system.
Domain 3 · ~10%Essentials of Diagnostic Radiology
Must-not-miss diagnoses: tension pneumothorax, aortic dissection, midgut volvulus, NAT findings. If you miss these, people die.
Domain 4 · ~5%Non-Interpretive Skills (NIS)
Quality & safety, contrast reactions, informatics (DICOM, PACS), ethics, HIPAA, critical-result communication. Tested, not reinforced clinically.
Learning loops Pick a mode — any domain, any time
MCQ Bank
ABR-style multiple choice with immediate rationale and references. Filter by domain or subtopic.
Image Cases
Stack-viewer cases with clinical stem. Identify the finding, then reveal diagnosis + differential.
Flashcards
Leitner-style spaced repetition for high-yield facts — formulas, dose limits, BI-RADS, contrast protocols.
Mock Exam
Timed, ABR-weighted full-length exam. Build stamina. See your domain breakdown at the end.
