1How many scored questions are on the ARDMS Breast (BR) specialty exam?
A.110
B.150
C.170
D.200
Explanation: The ARDMS Breast specialty examination contains 170 questions delivered in a 3-hour testing session, including hotspot and other Advanced Item Type questions.
2What is the current ARDMS examination fee for the Breast (BR) specialty exam?
A.$200
B.$275
C.$300
D.$350
Explanation: The Breast specialty exam fee is $300. The $275 figure is sometimes confused with this exam but it is actually the SPI (Sonography Principles & Instrumentation) fee.
3To earn the full RDMS (Breast) credential, a candidate must pass both the SPI and BR examinations within what time window?
A.2 years
B.3 years
C.5 years
D.7 years
Explanation: ARDMS requires the SPI and the specialty (BR) exam to be passed within 5 years of each other to earn the credential.
4Before beginning a breast ultrasound, the sonographer should verify patient identity using how many independent identifiers per Joint Commission standards?
A.One
B.Two
C.Three
D.Four
Explanation: Joint Commission National Patient Safety Goal NPSG.01.01.01 requires two patient identifiers (e.g., name and date of birth) before any procedure.
5A patient presents for a breast ultrasound and reports a latex allergy. Which item should be substituted first?
A.Ultrasound gel
B.Examination gloves
C.Transducer cover
D.Linen drape
Explanation: Standard examination gloves frequently contain latex; nitrile or vinyl alternatives must be used for latex-allergic patients.
6During a dense-breast supplemental screening, a patient asks why ultrasound is being added to her mammogram. The best response is:
A.Ultrasound replaces mammography in dense tissue
B.Dense tissue can mask cancers on mammography, so ultrasound improves detection
C.Ultrasound has higher radiation than mammography
D.Ultrasound is required by law for all women
Explanation: Dense fibroglandular tissue appears white on mammography and can hide cancers that also appear white. Adjunct ultrasound improves detection in BI-RADS density C and D breasts.
7After scanning, what is the appropriate first action regarding the transducer between patients?
A.Wipe with dry tissue only
B.Disinfect with low-level disinfectant per manufacturer's instructions
C.Sterilize with steam autoclave
D.Soak in 10% bleach for 30 minutes
Explanation: For non-critical transducers contacting intact skin, low-level disinfection (e.g., approved wipes) per manufacturer's IFU is the standard between patients.
8Which patient position is most commonly used for examining the lateral aspect of the breast?
A.Supine
B.Prone
C.Contralateral posterior oblique
D.Trendelenburg
Explanation: Rolling the patient into a contralateral posterior oblique (CPO) position thins the lateral breast against the chest wall, improving image quality of lateral lesions.
9A male patient is referred for a breast ultrasound to evaluate a palpable subareolar mass. The most likely indication is:
A.Phyllodes tumor
B.Gynecomastia
C.Galactocele
D.Lactational mastitis
Explanation: Gynecomastia is the most common cause of male breast enlargement and palpable subareolar tissue, presenting as hypoechoic glandular tissue posterior to the nipple.
10A patient becomes vasovagal during a core needle biopsy. The first action is to:
A.Continue the procedure quickly
B.Stop the procedure and place the patient supine with legs elevated
C.Administer epinephrine
D.Call a code blue
Explanation: For vasovagal reaction, immediately stop the procedure, lay the patient flat with legs elevated, and monitor vitals. Most episodes self-resolve.

About the RDMS-BR Exam

ARDMS specialty credential for breast sonographers. Must be paired with SPI (Sonography Principles and Instrumentation) — both within a 5-year window — for full RDMS-BR credential. Validates expertise in breast anatomy/physiology/pathology, image optimization (high-frequency linear transducer, gain/TGC/focal zones, harmonic imaging, compounding), BI-RADS Atlas 5th Edition lesion characterization, supplemental screening for dense breasts (BI-RADS C/D), automated whole-breast scanning (ABUS), elastography (strain, shear wave), contrast-enhanced ultrasound (CEUS), and US-guided interventional procedures. Includes hotspot/Advanced Item Type questions.

RDMS-BR Study Tips from Top Performers

1Master BI-RADS lesion descriptors with malignancy probability for each category 0-6
2Know the fee distinction: SPI = $275, BR = $300 — both required within 5 years for RDMS-BR
3Memorize fibroadenoma vs IDC features: oval/parallel/circumscribed/hypoechoic vs irregular/NOT-parallel/non-circumscribed/hypoechoic with shadowing
4Understand elastography: strain (qualitative) vs shear wave (m/s); higher stiffness suggests malignancy
5Apply ABUS/AWBUS for dense breast screening (BI-RADS density C/D); coronal reconstruction is unique strength

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.
