Nuclear hepatobiliary imaging.

Recent improvements in hepatobiliary radiopharmaceuticals and the high prevalence of biliary tract disease have resulted in a larger role for hepatobiliary imaging in clinical applications. The use of hepatobiliary imaging in assessing hepatic blood flow, hepatocyte function, biliary drainage, and complications in patients with jaundice or abdominal pain or surgery, as well as its primary use in diagnosing acute cholecystitis, is discussed.
