Overview
Sonography is a sensitive and specific modality for diagnosis of acute cholecystitis; adjusted sensitivity and specificity for diagnosis of acute cholecystitis are 88% and 80%, respectively. The 2 major diagnostic criteria are cholelithiasis and sonographic Murphy's sign. Minor criteria include gallbladder wall thickening greater than 3mm, pericholecystic fluid, and gallbladder dilatation. [1] [2]
Hepatobiliary scintigraphy with technetium-99m DISIDA (bilirubin) analog is also sensitive and accurate for diagnosis of chronic and acute cholecystitis. It can also assess the ability of the gall bladder to expel bile (gall bladder ejection fraction), and low gall bladder ejection fraction has been linked to chronic cholecystitis. However, since most patients with right upper quadrant pain do not have cholecystitis, primary evaluation is usually accomplished with a modality that can diagnose other causes, as well. [1] [2]
