What is the definition or description of: hida scan?

Hepatobiliary scan: A hida scan or hepatobiliary scan is performed following intravenous administration of 99mtc-hida. This allows the specialist in nuclear medicine to look at the biliary tree both inside and outside the liver and to assess gallbladder function.

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.

See below: A hida scan is a type of nuclear imaging study. This means that it uses a radioactive chemical, or tracer, that helps highlight certain organs on the scan. Is an imaging procedure that helps 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.
