[Computed tomographic cholangiography. An alternative non-invasive diagnostic method in ductus choledochus calculi].

Computed tomographic cholangiography has not been mentioned as a diagnostic procedure in the demonstration of common bile duct calculi. Computed tomographic cholangiography demonstrated both calcified and non-calcified common bile duct calculi in two patients. Computed tomographic cholangiography can be employed in investigation of biliary tract disease in selected cases where endoscopic retrograde cholangiography is not possible and ultrasound and ordinary computed tomography fail.
