Good opacification of intrahepatic and common bile ducts.
The pancreatic duct is also opacified. No filling defect or contrast leak identified.
Normal drainage of contrast to the duodenum.
Non-ionic water-soluble contrast material is injected through a previously placed T-tube. Care should be taken not to inject air since even a small quantity of air can mimic a radiolucent biliary stone.
