BREAST ARDMS

BREAST ARDMS Which artifact may cause structures to look deeper than they actually are? - Propagation speed error The optimum operating frequency for a broad-bandwidth transducer would be : - 10 MHz In breast sonography, what is NOT significantly affected by the limited field of view when imaging superficial structures? - Temporal resolution Which of the following affects the actual intensity of the sound utilized for imaging? - Output power The dynamic range of a display is the : - Number of gray shades Using color/power doppler while a patient hums to better dilineate a mass is called : - Fremitus A standoff pad thicker than 1 cm is not recommended because it will : - Affect the optimal placement of the fixed elevation plane focus Which type of transducer does NOT allow the sonographer to vary the focusing capabilities? - Mechanical sector When taking patient history for a breast sonogram, what information from a previous mammogram would not be considered relevant? - Name of radiographer Image of amplitude is affected by : - Power, overall gain, and time gain compensation (TGC) High-frequency transducers used in breast imaging provide excellent resolution of breast tissues but limited : - Penetration When using the 123-ABC method of annotation, "B" would indicate : - Mass is in the mammary zone In the 123-ABC method of annotation, the number denote the : - Distance from the nipple Which method of patient positioning is the best for evaluation the medial aspect of the breast ? - Supine The two-handed technique is used to image : - The main breast duct and nipple Which of the following transducers would be the best choice for breast imaging ? - 10 MHz linear array
