Gallstone disease CT

Introduction

Overview

Overview

There are no CT scan findings associated with gallstone disease.

Computed tomography

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.
