A liver scan uses a radioactive material to help determine how well the liver or spleen is working.

Technetium scan; Liver technetium sulfur colloid scan; Liver-spleen radionuclide scan; Nuclear scan - technetium; Nuclear scan - liver or spleen

The health care provider will inject a radioactive material called a radioisotope into one of your veins. After the liver has soaked up the material, you will be asked to lie on a table under the scanner.

The scanner can tell where the radioactive material has gathered in the body. Images are displayed on a computer. You may be asked to remain still, or to change positions during the scan.

You must sign a consent form. You will be asked to remove jewelry, dentures, and other metals because they can interfere with the scanner's functions.

You may need to wear a hospital gown.

You will feel a sharp prick when the needle with the radioactive substance is inserted into your vein. You shouldn’t feel anything during the actual scan. If you have difficulty lying still or are very anxious, you may be given a mild sedative to help you relax.

The test can provide information about liver and spleen function. It is also used to help confirm other test results.

Currently, the most common use for a liver scan is to diagnose a condition called benign focal nodular hyperplasia, or FNH.
