What is a HIDA scan?

A HIDA scan is a procedure done to see how well your gallbladder is working.

The liver makes bile that helps your body break down the fat in food, and ducts carry bile to the gallbladder. The gallbladder is a small sac under your liver on your right side that stores bile. The bile duct carries bile to the small intestines. The bile helps you digest fats in the food you eat.

When is it used?

A HIDA scan is done to diagnose problems with the gallbladder. It may be done if you are having pain in the upper right side of your belly that your healthcare provider thinks may be caused by your gallbladder.

A gallbladder ultrasound may be done first. If the ultrasound is normal and doesn’t show any problems, the next step is a HIDA scan. The HIDA scan can help your provider diagnose:

The scan may be done as part of other tests.

How do I prepare for this procedure?

What happens during the procedure?

The technician will inject the radioactive tracer into your arm. The tracer attaches to the bile in your liver and gallbladder. With the tracer, pictures can be taken of your liver, gallbladder, and bile ducts to see how well the bile is flowing from the liver, through the gallbladder, and into the small intestine.

You will lie on your back on the table. A large camera will take pictures of the radioactive chemical as it passes through your liver system for about an hour. You may need to stay very still while the pictures are being taken. In some cases, you will need to return to the X-ray department later in the day or the next day for more scanning.

What happens after the procedure?

Usually you’re able to go back to your usual schedule after the scan. The radioactive tracer will leave your body over the next several hours mainly in your urine and bowel movements. The tracer does not cause you to be a danger to others. The day you have the scan it’s recommended that you flush twice after using the toilet and be especially sure to wash your hands well. You may be able to flush the tracer out faster by drinking lots of water.

Follow your healthcare provider's instructions. Ask your provider:

Make sure you know when you should come back for a checkup. Keep all appointments for provider visits or tests.

What are the risks of this procedure?

The scan has almost no risk. Allergic reactions to the tracer are very rare.
