In creased pericholecystic hepatic activity has a high-pos itive predictive value for the diagnosis of acute chole cystitis (37,38), and is frequently associated with gan grenous cholecystitis and perforation(37).
diagnostic success based on the pattern of gallbladder nonvisu alization with a pericholecystic rim sign before morphine to gallbladder nonvisualization after morphine in a group of patients undergoing morphine-augmented cholescintigraphy.
The gallbladder was examined for the recognized sono-graphic features of acalculous cholecystitis: gallbladder wall thickening, gallbladder distention, intramural gallbladder lucencies (striated gallbladder wall), pericholecystic fluid, gallbladder sludge, and Murphy's sign.
