Computed tomography (CT) scanning is more expensive and less sensitive than ultrasonography for the detection of gallbladder stones. CT scanning is often used in the workup of abdominal pain, as it provides excellent images of all the abdominal viscera. CT scanning is superior to ultrasonography for the demonstration of gallstones in the distal common bile duct.
