Ultrasound

Ultrasound, also referred to as sonography or diagnostic ultrasound, uses high-frequency sound waves to visualize soft tissue. Ultrasounds are frequently ordered to measure fetal anatomy during pregnancy, check for blood clots and to guide needle biopsy procedures of the breast, abdomen and pelvis. The imaging modality does not use any radiation to create images. Find news specific to cardiac ultrasound (echocardiography).
