The process of an abdominal CT scan is fairly simple. You will be asked to lie on you back on a narrow table. This table will slide in and out of the CT scanner during the test. You will most likely be asked to place your arms above your head so there is a clear view of the abdomen. Occasionally, dye may need to be injected into your veins. This allows certain images to be clearer during the scan.
As the scan begins, x-ray beams from the scanner rotate around you. The scanner contains small detectors that will be used to measure the x-rays of the abdomen. To receive clear images of the abdomen, it is important to lie very still during the scan. This may require you to hold your breath at some point.
