Breast Sonography Questions and Answers Latest Version Already Passed
What is the primary advantage of using breast sonography over mammography?✔✔It provides better visualization of dense breast tissue and can distinguish cystic from solid masses.
How does a simple cyst typically appear on a breast ultrasound?✔✔A simple cyst appears anechoic (black), with well-defined margins and posterior acoustic enhancement.
Why is ultrasound often used in conjunction with mammography in breast cancer screening?✔✔Ultrasound helps to evaluate lesions that are difficult to see on mammograms, particularly in dense breast tissue.
What is the role of Doppler ultrasound in breast sonography?✔✔Doppler ultrasound helps assess blood flow within a lesion, which can be useful in differentiating benign from malignant lesions.

How is a fibroadenoma typically described on a breast ultrasound?✔✔A fibroadenoma usually appears as a well-circumscribed, hypoechoic mass with smooth borders and homogeneous echotexture.
What is the significance of posterior acoustic shadowing in breast ultrasound?✔✔Posterior acoustic shadowing suggests that a mass is solid and is likely to be benign, such as in the case of a calcified fibroadenoma.
How does a malignant breast tumor generally appear on ultrasound?✔✔Malignant tumors typically appear as irregular, hypoechoic masses with spiculated margins and no posterior acoustic enhancement.
What is the importance of using a high-frequency transducer in breast sonography?✔✔A high-frequency transducer provides superior resolution, making it ideal for imaging superficial breast tissues.
Why is it important to assess the axillary region during breast sonography?✔✔Assessing the axillary region helps evaluate the presence of lymph nodes, which may indicate metastasis in cases of breast cancer.
