Hepatobiliary scintigraphy, with Tc-99m iminodiacetic acid analogs, is indicated for diagnosis of various acute and chronic hepatobiliary diseases. Cholescintigraphy often provides physiological and functional information on bile drainage in patients with suspected biliary obstruction and bile leakage. Important diagnostic information is gained after the assessment of blood flow to the liver, hepatic extraction, biliary excretion, patency of biliary tract and gallbladder contraction. We report cholescintigraphic findings of a patient with a T tube causing a functional biliary obstruction.
