Overview
A HIDA scan or hepatobiliary iminodiacetic acid (HIDA) scan is an imaging procedure to track the flow of bile from your liver to your small intestine and also to evaluate your gallbladder function.
Test Details
The procedure involves the injection of a small amount of a radioactive isotope and obtaining multiple timed images over a course of 1-4 hours. When you arrive to the Nuclear Medicine department a technologist will explain the test to you. You will be asked to lie onto our imaging table with the nuclear camera placed near your upper abdomen.

If the HIDA enters the bile ducts but does not enter the small intestine, then an obstruction of the bile duct (usu ally due to stones or cancer) is suspected. In a healthy person, HIDA will pass through the bile ducts and into the cystic duct to enter the gallbladder.
What is the MBQ of a HIDA?
Footnotes: This cholescintigraphy (HIDA) scan was performed with 75 MBq of Tc-99m given IV, with imaging commenced at 1 hr and an oral fat-rich meal given to stimulate gallbladder contraction. Radiotracer activity in the gallbladder is measured over time as the gallbladder empties through the cystic duct, assessing gallbladder function. A normal gallbladder ejection fraction under this protocol is > 33%. The patient in this case proceeded to cholecystectomy. Histopathology revealed patchy, light chronic inflammation with Rokitansky-Aschoff sinus formation.
