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 cannot see noncalcified gallbladder calculi, and cannot assess for a Murphy's sign. [1] [2]
Patient #1: CT demonstrates findings that are consistent with acute cholecystitis (gallstone in GB neck, perichol fluid, GB wall thickening)
