Choledocholithiasis

This patient has had a cholecystectomy but presents with recurrence of biliary symptoms.

A CT cholangiogram was performed after intravenous administration of meglumine iotroxate (Biliscopin). Biliscopin is preferentially excreted by hepatocytes, opacifying the biliary tree. In the case of severe liver impairment, Biliscopin is renally excreted. CT cholangiography provides high-resolution imaging of the biliary tree and is an alternative to MRCP or ERCP for biliary imaging.

The study shows multiple calculi within a dilated biliary tree.
