Overview

There are no CT scan findings associated with gallstone disease.

Computed tomography

• CT scan sensitivity for gallstones has been estimated to be 55 - 80%.
• Gallstones may be missed on CT because many stones are isodense with bile.
• CT findings include:
  • This imaging test may be used to visualise the entire main duct.
  • The ability of CT to find stones in the common bile duct approximates ultrasound.
  • In general, CT scan is a better test for more complicated problems, although it may be used together with ultrasound.
