How long does it take to have a HIDA scan done?

What does a HIDA scan diagnose?

A hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure used to diagnose problems of the liver, gallbladder and bile ducts. For a HIDA scan, also known as cholescintigraphy or hepatobiliary scintigraphy, a radioactive tracer is injected into a vein in your arm.

How accurate are HIDA scans?

Literature has shown that ultrasound has a sensitivity of 84-97% for diagnosing cholelithiasis [6], and a more variable sensitivity ranging from 48-94% for diagnosing acute cholecystitis [6, 8, 9]. On the contrary, HIDA scan has a sensitivity of 86-100% for diagnosing acute cholecystitis [6, 8, 9].

What do you need to know about a HIDA scan?

Your doctor might use a HIDA scan as part of a test to measure the rate at which bile is released from your gallbladder (gallbladder ejection fraction). A HIDA scan carries only a few risks. They include: Allergic reaction to medications containing radioactive tracers used for the scan

When to have a HIDA scan after a gallbladder scan?

HIDA scan is combined with other imaging (such as CT or ultrasound). After the gallbladder scan, the person may be prepared for surgery, if needed. Indications for HIDA scan. The HIDA scan should be done when ultrasound is not diagnostic and when there is a clinical diagnosis of acute cholecystitis.

Is the HIDA scan positive for cholecystokin?

Although the standard measure by which the HIDA scan is deemed positive is the presence of an ejection fraction (EF) of <35% following provocation with cholecystokinin (CCK), there still remains debate as to the usefulness of this measure.

Which is better the HIDA scan or CCK provocation?

Conclusions: The CCK HIDA scan is a useful study in the investigation of acalcalous cholecystitis; however, we would suggest that recreation of symptoms following CCK provocation is superior to EF for the identification of underlying chronic cholecystitis.

What should I expect during a HIDA scan?

Here’s what to expect at your HIDA scan: An imaging technician will instruct you to lie back on a table and stay very still. The technician will put an IV ( intravenous) needle into a vein in your arm or hand. The technician will inject a radioactive tracer into the IV so it enters your vein.

Why would I need a HIDA scan?

A HIDA, or hepatobiliary, scan is a diagnostic test. It’s used to capture images of the liver, gallbladder, bile ducts, and small intestine to help diagnose medical conditions related to those organs.

How does a HIDA scan usually take?

During a HIDA scan, a camera takes pictures of your gallbladder after a radioactive tracer is injected into a vein in your arm. The tracer travels through your liver, gallbladder, bile ducts, and small intestine. The camera takes a series of pictures of the tracer as it moves along.
