ARRT Breast Sonography Examination Practice Test
Breast sonography evaluates breast and axillary anatomy, palpable findings, and abnormalities identified on other imaging. The practice material samples lesion morphology, acoustic artifacts, inflammatory conditions, and postsurgical changes, alongside image optimization and preparation for ultrasound-guided procedures. These topics connect image appearance with the clinical question and the next step in a targeted examination.
Exam overview
About the ARRT Breast Sonography Examination Exam
Useful breast ultrasound interpretation depends on assessing lesion shape, orientation, margins, echogenicity, and relationship to surrounding tissue rather than relying on a single feature. Practice topics include recognizing suspicious patterns such as a non-circumscribed margin or a mass taller than wide, and distinguishing benign-appearing axillary node features. Artifact recognition matters too: repeated echoes beneath a strong reflector can create misleading structures at increasing depths. Clinical context helps guide scanning, including evaluating a painful erythematous breast for a possible drainable abscess and considering fat necrosis after surgery or trauma. Technical choices such as focal-zone placement and consistent transducer coupling affect depiction of small lesions. Reviewing prior imaging supports targeted localization, while real-time visualization during needle advancement helps maintain the biopsy needle’s path toward the intended target.
Sample Practice Questions
Review a selection from this exam's published US Practice Tests practice bank.
Which feature of a breast mass margin is generally more concerning than a circumscribed margin?
Show answer
Correct answer: AAn indistinct margin can reflect an infiltrative interface and is generally more suspicious than a smooth circumscribed margin. Margin assessment should be made in more than one plane and interpreted with other sonographic features.
A breast ultrasound image shows a small structure repeated at progressively greater depths beneath a strong reflector. Which artifact most likely explains this pattern?
Show answer
Correct answer: BReverberation occurs when sound repeatedly reflects between strong interfaces before returning to the transducer, producing repeated echoes displayed at increasing depths.
A patient who is breastfeeding has a painful, erythematous region of the breast and fever. Which ultrasound finding would be most consistent with a drainable abscess?
Show answer
Correct answer: AAn abscess commonly appears as a complex fluid collection, often with debris and surrounding inflammatory change. Clinical signs such as fever and localized erythema support the need for prompt clinical evaluation.
A patient with a prior breast operation has a small, firm area near the surgical scar. Which benign process can produce an irregular hypoechoic lesion after surgery or trauma?
Show answer
Correct answer: AFat necrosis may follow surgery, trauma, or radiation and can have variable sonographic appearances, including an irregular hypoechoic area. Clinical history and correlation with other imaging help guide interpretation.
Why is it useful to review prior breast imaging before beginning a targeted ultrasound examination?
Show answer
Correct answer: APrior imaging can clarify the area of concern and provide context for comparison, helping the sonographer perform a focused examination. It does not replace current documentation or definitive diagnostic assessment.
A breast lesion is being considered for ultrasound-guided core biopsy. What is a key purpose of real-time imaging during needle advancement?
Show answer
Correct answer: AReal-time ultrasound allows the operator to track the needle and verify its position relative to the target and nearby structures during the procedure. Tissue sampling is required for histologic diagnosis.
What is the primary advantage of using the smallest practical focal zone when evaluating a small breast lesion?
Show answer
Correct answer: AThe ultrasound beam is narrowest near the focal zone, improving lateral resolution there and helping distinguish small adjacent structures.
How to use this practice test
The free practice bank contains 50 questions, with up to 20 random questions in a session. Use a session to check how well you interpret breast and axillary findings, recognize artifacts, and apply scanning or biopsy principles. Results appear after the session, helping identify concepts to revisit.
Preparation tips
- Compare lesion margins, shape, and orientation; explain why an irregular or taller-than-wide mass may warrant greater concern than a circumscribed, wider-than-tall finding.
- Practice identifying reverberation patterns beneath strong reflectors and distinguish artifact from a true structure by considering its repeated, progressively deeper appearance.
- Relate clinical presentation to sonographic assessment: review the features that can support a drainable abscess in a patient with fever, erythema, and focal breast pain.
- For small lesions, place the focal zone at the target and maintain adequate coupling and steady probe contact to preserve detail and reduce avoidable image-quality variation.
- Review how prior imaging guides targeted scanning, and how real-time needle visualization supports accurate advancement during ultrasound-guided core biopsy.
