Liver scan

Definition:

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



Alternative Names:

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



How the test is performed:

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, hold your breath for short period of time, or to change positions during the scan.



How to prepare for the test:

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.



How the test will feel:

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.



Why the test is performed:

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



Normal Values:

The liver and spleen should appear normal in size, shape, and location. The radioisotope is absorbed evenly.



What abnormal results mean:

Additional conditions under which the test may be performed:



What the risks are:

There is some concern with radiation from any scan. However, the level of radiation in this procedure is less than that of most x-rays and is not considered significant enough to cause harm to the average person.

Pregnant or nursing women should consult their health care provider before any exposure to radiation, because fetuses and nursing babies are more sensitive to the effects of radiation.



Special considerations:

Other tests may be needed to confirm the findings of this test. Additional tests may include an abdominal ultrasound , abdominal CT scan , liver biopsy , or liver flow study.
