A hepatobiliary scan (HIDA scan) is done to evaluate the function of the liver in making and excreting bile, and the drainage system (bile ducts) and gallbladder for possible blockage or malfunction.

What does a Hepatobiliary Scan Entail?

You will lie flat on your back on the imaging table. You will receive an injection of a radioactive substance in a vein in your arm. This material travels through the bloodstream, and is eventually cleared from the bloodstream by the liver. You will not feel anything from this injection.

During the scans the camera will be positioned over you. Images will be recorded for up to one hour, or rarely, longer. For some patients, a second injection through the same single needle stick will be done later during the test. This can be done to either help the gallbladder show up better (using morphine), or to trigger it to empty (using CCK/cholecystokinin).

Is Any Special Preparation Required Before Having a Hepatobiliary Scan?

You should have had nothing to eat or drink (NPO) for at least 4-6 hours before beginning the test. You can take your regular medicines with a sip of water.

How Long Will It Take?

About 60 minutes.

How Will I Learn the Results?

You may call your doctor to discuss the results.

If you are or suspect you might be pregnant, please tell your doctor, nurse or technician.
