liver scan
(liv-er skan)
An image of the liver created on a computer screen or on film. A radioactive substance is injected into a blood vessel and travels through the bloodstream. It collects in the liver, especially in areas that are suspected to be abnormal. The scanner identifies these areas of concern.
A CT (CAT) scan can be used as a liver scan.
