Frequently Asked Questions
What's the difference between ARDMS BR and ARRT BS?
Both credential breast sonographers but represent different professional bodies. ARDMS BR (RDMS-BR) is the diagnostic medical sonography credential — requires SPI prerequisite, costs $300. ARRT BS is the radiologic technology post-primary credential for technologists already credentialed in Radiography, Sonography, Nuclear Medicine, or Radiation Therapy — costs $225. Many breast sonographers hold both.
Is the ARDMS BR fee $275 or $300?
$300 is the correct ARDMS BR fee per the ARDMS official site. $275 is sometimes incorrectly cited but $275 is actually the SPI (physics prerequisite) fee. Don't confuse the two — you'll pay $275 for SPI + $300 for BR + within 5 years to earn the full RDMS-BR credential.
What is breast elastography?
Breast elastography measures tissue stiffness as a complementary BI-RADS feature. STRAIN elastography (qualitative): patient breath-hold compression cycles produce elasticity images; strain ratio and elasticity-to-B-mode ratio (E/B) >1.0 suggests malignancy. SHEAR WAVE elastography (quantitative): m/s velocity reading; benign typically <2-3 m/s, malignancy often >4-5 m/s (institutional thresholds vary). Used to upgrade BI-RADS 3 (consider biopsy) or downgrade BI-RADS 4A (consider follow-up).
How should I study for ARDMS BR?
Plan 60-100 hours over 8-12 weeks. Focus on Anatomy/Pathology (25%), Lesion Characterization/BI-RADS (25%), and Procedures/Image Optimization (20%). Master BI-RADS Atlas 5th Ed, common pathology distinctions (fibroadenoma vs IDC), image optimization for breast (high-frequency linear, harmonic, compounding), and elastography. Familiarize yourself with hotspot/Advanced Item Type question format.
