Abdominal ultrasound is a scanning technique used to image the interior of the abdomen. Like the X-ray, MRI, and CT scan, it has its place as a diagnostic tool. Ultrasound scans use high frequency sound waves to produce an image and do not expose the individual to radiation. The procedure is painless and safe.
