What is a HIDA Scan?
For a HIDA scan, also known as cholescintigraphy and hepatobiliary scintigraphy, a radioactive tracer is injected into a vein in your arm. The tracer travels through your bloodstream to your liver, where the bile-producing cells take it up. The tracer then travels with the bile into your gallbladder and through your bile ducts to your small intestine.
A nuclear medicine scanner (gamma camera) tracks the flow of the tracer from your liver into your gallbladder and small intestine and creates computer images.
A hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure used to diagnose problems of the liver, gallbladder and bile ducts.
Preparing For Your HIDA Scan
- No food or drink (4) four hours before your scan.
- You may wear your own clothing, such as jogging, leggings, or sweat pants, as long as there are no metal fasteners, zippers, buttons, etc. Hospital gowns are available.
- Jewelry and other accessories should be left at home, if possible, or removed prior to the scan.
Walk-in Patients: Please be sure to bring the signed order from your physician requesting the examination and your insurance card.
After Your HIDA Scan
In most cases, you can go about your day after your scan. The small amount of radioactive tracer will lose its reactivity or pass through your urine and stool over the next day or two. Drink plenty of water to help flush it out of your system.
How Soon Will Scan Results Be Available?
Your images are reviewed, and results interpreted by one of our qualified doctors who specializes in reading images (radiologist). The Radiologist will prepare a report, which is electronically sent to your doctor as soon as available, usually within 24-48 hours
