CT diagnosis of common bile duct stone

Abstract

Common bile duct stones were demonstrated as high-density objects on CT in 22 of 45 cases. About 96% of the remaining cases (22 of 23) exhibited other abnormal CT findings which included common bile duct dilatation, concomitant gallbladder stones, and/or presence of intraductal air. CT is a useful diagnostic modality in the elevation of patients with suspected choledocholithiasis.
