Hepatobiliary scintigraphy (HIDA scan) can be useful in confirming the diagnosis of acute cholecystitis. The study employs a technetium-labeled iminodiacetic acid agent that is excreted into the bile ducts. Subsequent images are taken, which in a normal study should fill the gallbladder, extrahepatic ducts, and duodenum. In the case of cystic duct obstruction, a positive study fails to show the gallbladder filling. The sensitivity and specificity of this study are high, with results approaching 90 to 100
