CT can be used to diagnose and stage acute cholecystitis, including complications such as emphysematous, gangrenous, and hemorrhagic cholecystitis;gallbladder perforation; gallstone pancreatitis; gallstone ileus; and Mirizzisyndrome. CT also can be used to evaluate acute biliary diseases such as biliarystone disease,benign and malignant biliary obstruction, acute cholangitis,pyogenic hepatic abscess, hemobilia, and biliary necrosis and iatrogenic complications such as biliary leaks and malfunctioning biliary drains and stents (Stephenetal., 2013).
