What is the primary purpose of breast ultrasound in clinical practice?
✔✔To evaluate palpable lumps and differentiate cystic from solid masses
Which transducer frequency is most commonly used for breast ultrasound?
✔✔High-frequency linear probe, 10–15 MHz
Why is patient positioning important during breast ultrasound?
✔✔To allow optimal visualization of all breast tissue and improve image quality
Which breast tissue layer lies immediately beneath the skin?
✔✔Subcutaneous fat layer
Which breast tissue layer contains the ducts and glandular tissue?
✔✔Fibroglandular layer
1
,What is the primary purpose of color Doppler in breast imaging?
✔✔To assess vascularity of a lesion
What characteristic differentiates a simple cyst from a complex cyst on ultrasound?
✔✔Simple cysts are anechoic with posterior acoustic enhancement; complex cysts have internal
echoes or septations
Which orientation is preferred for scanning the breast: transverse or longitudinal?
✔✔Both transverse and longitudinal views are obtained for accurate assessment
Why is it important to include the nipple in the ultrasound field?
✔✔To evaluate subareolar lesions and ducts
Which type of mass is most likely benign on ultrasound?
✔✔Oval, well-circumscribed, hypoechoic, and parallel to the skin
Which feature is more suggestive of malignancy on breast ultrasound?
✔✔Irregular shape, spiculated margins, and non-parallel orientation
2
,What is posterior acoustic enhancement, and what does it indicate?
✔✔Increased echo intensity behind a structure, often seen with cysts
What is posterior acoustic shadowing, and what does it indicate?
✔✔Decreased echo intensity behind a structure, often associated with solid or malignant masses
Why is bilateral scanning recommended during breast ultrasound?
✔✔To compare symmetry and detect subtle abnormalities
What is the purpose of elastography in breast ultrasound?
✔✔To assess tissue stiffness and help differentiate benign from malignant lesions
Which breast quadrant has the highest incidence of malignancy?
✔✔Upper outer quadrant
Why is careful documentation of lesion location essential in breast ultrasound?
✔✔To guide biopsy, follow-up, and correlate with mammography
3
, Which technique improves visualization of small superficial lesions?
✔✔Using a standoff pad or thick layer of gel
Why should a sonographer adjust gain settings appropriately?
✔✔To optimize image quality and prevent over- or underestimation of echogenicity
Which breast lesion is typically anechoic with thin walls and posterior enhancement?
✔✔Simple cyst
Which ultrasound feature suggests an intraductal lesion?
✔✔Ductal dilation with a hypoechoic or echogenic mass within the duct
What is the primary advantage of handheld breast ultrasound over automated breast ultrasound?
✔✔Dynamic scanning with real-time evaluation and compression adjustment
Why is it important to note lesion size in three dimensions?
✔✔For accurate follow-up, comparison, and biopsy planning
