Diagnosis of acute cholecystitis using hepatobiliary scintigraphy with sup(99m)Tc-PMT

Hepatobiliary scintigraphy with sup(99m)Tc-PMT was applied to 80 patients in benign biliary diseases (excluding cholecystectomized patients) for the diagnosis of acute cholecystitis. According to the conventional diagnostic criterion based on nonvisualization of the gallbladder on acute cholecystitis, the specificity, efficiency and predictability positive test were 63 %, 72 % and 45 %, respectively. When delayed intestinal transition of radioactivity was added to this conventional criterion, the diagnostic value was significantly elevated (p < 0.01); the specificity, efficiency and predictability positive test were 97 %, 97 % and 90 %, respectively. The delayed intestinal transition of radioactivity should be considered on diagnosis of acute cholecystitis. (author)
