Abdominal CT Scan (Computed Tomography Scan)
What is the test?
CT scans are pictures taken by a specialized x-ray machine. The machine circles your body and scans an area from every angle within that circle. The machine measures how much the x-ray beams change as they pass through your body. It then relays that information to a computer, which generates a collection of black-and-white pictures, each showing a slightly different "slice" or cross-section of your internal organs. Because these "slices" are spaced only about a quarter-inch apart, they give a very good representation of your internal organs and other structures.
Doctors use CT scans to evaluate all major parts of the body, including the abdomen, back, chest, and head.
