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%.[1]
- 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.
