Computed Tomography (CT or CAT) Scan of the Liver and Biliary Tract
Computed tomography (CT or CAT scan) is a noninvasive diagnostic imaging procedure that uses a combination of computer technology and X-rays to produce images of the body.
CT scans may be done with or without “contrast.” Contrast refers to a substance taken by mouth and/or injected into an intravenous (IV) line that causes the particular organ or tissue under study to be seen more clearly.
CT scans of the liver and biliary tract (the liver, gallbladder, and bile ducts) can provide more detailed information about the liver, gallbladder, and related structures than standard X-rays of the abdomen, thus providing more information related to injuries and/or diseases of the liver and biliary tract. CT scans of the liver and biliary tract may also be used to visualize placement of needles during biopsies of the liver or during aspiration (withdrawal) of fluid from the area of the liver and/or biliary tract.
