Overview
The reported sensitivity and specificity of 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 calculi outside the lumen of the gallbladder.
CT scan
- CT scan is more specific than ultrasound. CT scan findings include:[1][2][1]
- Gallbladder wall thickening
- Gallbladder distension or contraction
- Subserosal edema
- High attenuation gallbladder bile
- CT cannot identify noncalcified gallbladder calculi, and cannot assess for Murphy's sign.[3][4]
Acalculous Cholecystitis
The CT based diagnostic criteria from multiple studies for acalculous cholecystits is as follows.[5]
| 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: 2 major or 1 major and 2 minor
