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. 2 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. 3 What does a complex cyst in breast sonography indicate? A complex cyst may have internal echoes, septations, or mural nodules, and requires further evaluation to rule out malignancy. What is elastography in breast ultrasound used for? Elastography measures tissue stiffness, which can help differentiate between benign and malignant lesions, as malignant tumors are typically stiffer. What is the typical appearance of a galactocele on breast ultrasound? A galactocele appears as a well-defined, round or oval, hypoechoic mass, often with internal debris or a milk-like content. What is the function of the standoff pad in breast ultrasound? A standoff pad is used to visualize superficial lesions more clearly by reducing the distance between the transducer and the skin. Why is it necessary to perform a full evaluation of the contralateral breast during a sonographic examination? 4 Evaluating the contralateral breast helps in detecting potential bilateral abnormalities and allows for better comparison with the affected side. What is the significance of an irregularly shaped,
