ABR IR/DR study guide
ABR IR/DR · Work through your exam, one topic at a time.
The ABR IR/DR certification is a combined Interventional Radiology and Diagnostic Radiology credential awarded by the American Board of Radiology, a not-for-profit organization and member of the American Board of Medical Specialties. The ABR describes its mission as certifying "that our diplomates demonstrate the requisite knowledge, skill, and understanding of their disciplines to the benefit of patients," and its vision as assuring "the highest standards of specialty expertise and professionalism in the radiological sciences." The credential is intended for physicians completing ABR initial certification in the combined IR/DR pathway, who must demonstrate competence across both interventional and diagnostic radiology rather than in a single discipline. Because the combined pathway spans two broad bodies of knowledge, preparation should be built around both domains rather than one: interventional procedural knowledge, patient selection, and periprocedural management on one side, and the full breadth of diagnostic imaging interpretation on the other. This page is an independent study resource. Topics on this exam: Interventional Radiology and Diagnostic Radiology. The ABR IR/DR study guide has 2 sections and about 641 words.
01Interventional Radiology: Core Principles, Safety, and Exam Traps
Interventional radiology questions test procedural decision-making, periprocedural pharmacology, device and technique selection, and complication recognition. Organize study around four pillars: (1) pre-procedure assessment, (2) image-guided access and navigation, (3) embolic/occlusive and revascularization techniques, and (4) periprocedural management and complications. Know coagulopathy thresholds and when correction is warranted; know contrast allergy premedication regimens and when to substitute CO2 or gadolinium; know renal-protection strategies (hydration, minimizing volume, avoiding nephrotoxins). Recognize that most periprocedural antibiotics are indicated only for specific scenarios (e.g., biliary intervention, solid-organ embolization, certain drains), not universally.

Diagnostic radiology questions reward a systematic search pattern and knowledge of disease-specific imaging features. Build frameworks for chest, abdomen, neuro, and musculoskeletal imaging. For each modality, know its strengths and limitations: CT for acute hemorrhage and bone detail, MRI for soft-tissue characterization and marrow, ultrasound for real-time and non-ionizing assessment, and radiography for initial triage. Understand density/signal characteristics across modalities (e.g., fat, fluid, hemorrhage, calcification).
