Overview
Sonography is a sensitive and specific modality for diagnosis of acute cholecystitis; adjusted sensitivity and specificity for diagnosis of acute cholecystitis are 88% and 80%, respectively. The 2 major diagnostic criteria are cholelithiasis and sonographic Murphy's sign. Minor criteria include gallbladder wall thickening greater than 3mm, pericholecystic fluid, and gallbladder dilatation. [1] [2]
Ultrasound
- This is the first test to be done in any suspected case cholecystitis.
- Sonography is the most cost effective, accurate and fast diagnostic modality.
- Sensitivity is reported to be as high as 90-95%.
- Acute calculous cholecystitis is diagnosed radiologically by the presence of
- Thickening of gall bladder (5mm or greater)
- Pericholecystic fluid
- Probe tenderness (ultrasonographic Murphy's sign)
