==Overview==
The reported sensitivity and specificity of [[computed axial tomography|CT scan]] findings are in the range of 90-95%. CT is more sensitive than ultrasonography in the depiction of pericholecystic inflammatory response and in localizing pericholecystic abscesses, pericholecystic gas, and [[calculus (medicine)|calculi]] outside the [[lumen]] of the gallbladder.
CT scan findings associated with chronic cholecystitis include [[gallbladder wall thickening]], [[gallbladder]] distension or contraction and subserosal edema.

Overview

CT scan findings associated with chronic cholecystitis include gallbladder wall thickening, gallbladder distension or contraction and subserosal edema.

CT scan

Acalculous Cholecystitis

The CT based diagnostic criteria from multiple studies for acalculous cholecystits is as follows:[7]

Criteria Diagnosis
Major 3 to 4 mm wall thickness
Pericholecystic fluid
Subserosal edema
Intramural gas
Sloughed mucosa
Minor Hyperdense bile (sludge)
Subjective distension (hydrops)

Diagnosis: The diagnosis requires 2 major or 1 major and 2 minor to be positive.
