About the Breast (BR) Exam

The ARDMS Breast (BR) specialty exam covers breast anatomy, the ACR BI-RADS lexicon, benign and malignant pathology patterns, image-guided procedures, and supplemental screening. The BI-RADS framework is the organizational backbone of the entire exam and must be understood at a category-by-category level.

About the Pediatric Sonography (PS) Exam

The ARDMS Pediatric Sonography (PS) specialty exam tests age-specific anatomy, neonatal pathology, and clinical skills that differ fundamentally from adult sonography. Key content areas include neonatal cranial ultrasound, developmental dysplasia of the hip (DDH), pyloric stenosis, and the spectrum of pediatric abdominal and genitourinary pathology.

Which Exam Should You Take First?

The right choice depends on your clinical background, your current employer's needs, and your long-term career goals. Sonographers with strong clinical experience in breast imaging should consider the BR exam first, as applied clinical knowledge transfers directly to board performance. Similarly, those working predominantly in pediatric sonography settings will find the PS exam more immediately supported by their daily practice.

Both credentials are valuable additions to a multi-specialty credential portfolio. The 2025 first-time pass rates — 77% for BR and 71% for PS — underscore the importance of structured, domain-aligned preparation for whichever exam you choose first.
