Definition
By Mayo Clinic staffHIDA scan is an imaging procedure that helps your doctor track the production and flow of bile from your liver to your small intestine. Bile is a fluid produced by your liver that helps your digestive system break down fats in the foods you eat.
A HIDA scan, which stands for hepatobiliary iminodiacetic acid scan, creates pictures of your liver, gallbladder, biliary tract and small intestine. A HIDA scan can also be called cholescintigraphy, hepatobiliary scintigraphy or hepatobiliary scan.
A HIDA scan is a type of imaging study called a nuclear medicine scan. This means the HIDA scan uses a radioactive chemical or tracer that helps highlight certain organs on the scan.
