What happens during a hida scan?

See below: A radioactive tracer is injected into your veins. This is taken up by the liver and excreted in bile. It can then be followed using a camera to see that it empties into your intestine. If you have a gallbladder one can see if it functions properly too.

Gall bladder test: The patient is injected intravenously with tc99m hida (radiotracer). The liver extracts the material from blood stream and excretes it into bile ducts, gall bladder, and bowel.(30-60 min imaging) usually when gall bladder is full, patient is injected IV with cck (hormone to contract gb)patient may experience some pain, and calculate % of gb emptying(60 min. Imaging) normal usually > 35% in adults.

First a radioactive: Drug (usually disofenin) in injected in a vein and images taken for the next hour over the anterior abdomen. In some patients, once certain anatomic structures are seen, kinevac, an analog of the hormone cck is administered via slow IV infusion to determine how well the gallbladder functions. The test allows nuclear medicine or radiology physicians to see the liver, bile ducts and gallbladder.
