What is a hida scan?

HIDA scan. Is a nuclear medicine test that evaluates the gallbladder, bile ducts, and liver. Pictures are taken after a special dye is injected into a vein. The patient may be given a fatty meal.
Hepatobiliary study. Patient is injected intravenously with isotope tagged to chemical hida that is extracted preferentially by liver cells mimicking bile. Some of this is stored in gall bladder and some enters small bowel from common bile duct. Cholecystokinin is a natural hormone slowly injected intravenously to stimulate gall bladder contraction. Normal function has at least 50% emptying of gall bladder.

What can a hida scan find that an ultrasound cannot find? Aren't there multiple things other than gallbladder dysfunction? Ultrasound was normal.

A lot. After the tracer is injected into a vein, it must circulate to the liver. The liver must remove it from the blood and put it into the bile, liver circulation and function assured. The tracer, now in the bile, travels through the bile system and into the gall bladder, checking patency of these. A gall bladder stimulant can be used to measure gall bladder function and ejection out into bowel. Read more...
US vs. HIDA. Us is a form of anatomical imaging. Hida is more of a functional imaging. Us can show anatomic signs of cystic duct obstruction. Often physicians look for gallbladder wall thickening or pericholecystic fluid on us. On hida, physicians look to see if tracer enters the gallbladder lumen or bowel to rule out cystic duct or common duct obstruction. Hida can also give gallbladder ejection fraction. Read more...
Anatomic vs function. Ultrasound is anatomic test looking for stones, sludge, or gb wall thickening. HIDA scan is physiologic looking at function of gb.HIDA sees response of gb to cholecystokinin or fatty meals.Sometimes patient experiences similar symptoms to gb attack. Read more...

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. Read more...
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. Read more...
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. Read more...

What does 8 % on Hida scan mean?

Ejection fraction. The ejection fraction is the portion of the gallbladder contents that are expressed from the gallbladder with contraction. Normally the gallbladder has an ejection fraction greater than 35%. An EF of 8% may indicate abnormal gallbladder function, and it needs to be considered along with the clinical situation to determine if a cholecystectomy should be performed. Good luck. Read more...

What exactly is a hida scan and what does it involve?

Gall bladder scan. A hida scan may be used to evaluate for acute or chronic cholecystitis or gall bladder dysfunction/dyskinesia. The patient does not have to do much but stay still. It helps show whether your liver, gallbladder or sphincter are malfunctioning. Read more...
Gall bladder test. Hida scan (disida or pipida) involves intravenous iinjection of radiopharmaceutical that is extracted from the blood stream by the liver and then excreted for visualization of gall bladder, bile ducts, and bowel. This test can identify gall bladder disease, bile duct obstruction, and reduced liver function. Read more...

What is observed during a hida scan?

One/ two phase exam. Hida scan is usually two part examination.First phase intravenous injection of isotope with technetium accumulating in liver, excreted like bile into bile ducts, accumulating in gall bladder, and excreted into bowel.Second phase slow intravenous injection of cck, hormone, causing gb contraction determing gb ejection fraction.Sometimes discomfort mimicing abdominal symptoms.Looking for gb disease, Read more...
