NCI's Dictionary of Cancer Terms provides easy-to-understand definitions for words and phrases related to cancer and medicine. Ultrasound is most useful in assessing very dense breasts because of the low sensitivity of mammography in these cases. After deformation, the tissue level used in ultrasound elastography measurement could be estimated on the deformed supine magnetic resonance imaging to measure the breast density in the corresponding tissue region. Breast Ultrasound Ultrasound of Soft Tissues and Surface Structures Breast ultrasound is a diagnostic procedure during which the structure of breast tissues is displayed on the monitor using ultrasound waves.
