Hepatobiliary scintigraphy is a radionuclide diagnostic imaging study that evaluates hepatocellular function and the biliary system by tracing the production and flow of bile from the formative phase in the liver, and its passage through the biliary system into the small intestine. Sequential (or dynamic) images of the liver, biliary tree, and gut are obtained. Computer acquisition and analysis, including pharmacologic interventions, are used according to varying indications and an individual patient’s needs.
