Hydroxy Iminodiacetic Acid Scan


What do I need to know about a hydroxy iminodiacetic acid scan?

A hydroxy iminodiacetic acid (HIDA) scan is a test to show how your liver and gallbladder are working. This test is also called cholescintigraphy.

How do I prepare for a HIDA scan?

Do not eat or drink anything for 4 hours before the test. Tell your healthcare provider about all medicines that you take. You may need to stop taking certain medicines before the test. Some pain medicines may affect the results.

What will happen during a HIDA scan?

A radioactive substance called a tracer will be injected into a vein, usually in your hand or arm. A healthcare provider will position a camera above your stomach and take pictures every 5 to 15 minutes for 1 to 2 hours. More scans may be taken within 24 hours after you have received the tracer. Your healthcare provider will tell you when to return if more scans are needed.

What are the risks of a HIDA scan?

Rarely, you may develop an allergic reaction to the tracer. The area where the tracer was injected could become red, swollen, or painful.
