Abstract
Objective
The objective of this study was to determine the most predictive CT feature of the
mild forms or early manifestations of acute cholecystitis.
Materials and Methods
Two radiologists analyzed CT of 34 patients with mild or early acute cholecystitis
and 34 control patients for pericholecystic increased attenuation on the arterial
phase, indistinctness of the interface between the gallbladder (GB) and the liver,
enhancement of the GB wall, and increased attenuation of the GB bile.
Results
There were significant differences in the mean values for each CT feature but increased
attenuation of the GB bile between patients and control group (P<.05). The most significant predictor of mild or early acute cholecystitis on CT was
the presence of pericholecystic increased attenuation on the arterial phase (sensitivity,
82.4%), followed by indistinctness of the interface between the GB and liver (sensitivity,
38.0%), which were identified by both observers with good agreement (κ=0.735 and κ=0.687).
Conclusions
The pericholecystic increased attenuation on arterial phase CT was the most significant
predictor of mild forms or early manifestations of acute cholecystitis.
