Complete Abdominal Ultrasound Exam

What is a complete abdominal ultrasound?

A complete abdominal ultrasound is a type of diagnostic imaging test that uses sound waves to look at the organs and other structures within the abdomen. A small probe handled by the doctor slides directly on the skin with the help of some gel. The probe, called a transducer, emits high-frequency sound waves which travel through the body and then are collected when they bounce back, like an echo, by the same probe, creating an image on the screen. This procedure is noninvasive, painless and safe, it does not use any kind of harmful radiation and it shows real time images. For these reasons, it is the procedure of choice to examine the fetus in pregnant women, to check the blood flow through blood vessels or to guide needles when performing biopsies.
