8 A Double Contrast Study The bowel is distended with air, and a small volume of barium is used to coat the mucosaHow has the patientbeen positioned?
12 Percutaneous Transhepatic Cholangiography Water-soluble contrast material is injected directly into the liver via a fine needle introduced through the skingallbladder

14 Postoperative Cholangiogram Water-soluble contrast was injected into the biliary system via a tube left in place following removal of the gallbladder (cholecystectomy)right hepatic ductleft hepatic ductcommon hepatic ductcommon bile ductpancreatic ductduodenum
