Received March 5, 1999; revision requested April 27; revision received May 19; accepted August 30. Address reprint requests to S.C. (e-mail: chopra@uthscsa.edu).
Twenty asymptomatic volunteers underwent helical computed tomographic (CT) cholangiography 1012 hours after ingesting iopanoic acid. Three observers assessed the images for the extent of bile duct visualization and image quality. The common bile duct and common hepatic duct were adequately visualized in 19 (95%) subjects. Helical CT cholangiography with oral cholecystographic contrast material is feasible and deserves further clinical studies.
