A procedure used to check for abnormal areas in the liver or spleen. A very small amount of a radioactive substance is injected into a vein and travels through the blood to the liver and spleen. It is detected by a scanner linked to a computer, which forms an image of the areas where the radioactive substance collects. A liver-spleen scan may be used to help find cancer in the liver or spleen, cirrhosis, hepatitis, and other liver or spleen problems.
