A HIDA scan (hepatobiliary scintigraphy) is a nuclear medicine test of the gallbladder and bile ducts. It shows gallbladder function and bile flow. Typical effective dose 2 to 4 mSv, similar to about 1 year of natural background radiation (about 3 mSv a year).

Gallbladder function and bile flow.
Suspected acute cholecystitis, bile leak.
Fast 4 to 6 hours.
Typical effective dose 2 to 4 mSv, similar to about 1 year of natural background radiation (about 3 mSv a year). Tell staff if you are or might be pregnant; the benefit usually outweighs the small risk, and shielding or alternatives can be considered.
