Ultrasound is a non-invasive procedure that uses sound waves in the assessment of body structures. A gel is applied to the skin over the area to be scanned. An ultrasound transducer is then pressed onto the skin. It produces sound waves and “reads” the echo produced in the body. The echo is processed by a computer into detailed images.This procedure is most commonly used for abdominal, pelvic and obstetrical evaluation. Other uses can include the assessment of vascular structures, such as veins and arteries, or superficial soft tissue abnormalities. Ultrasound procedures are performed by qualified Ultrasound technologists. This procedure uses no radiation.
