Intrahepatic Versus Extrahepatic Cholestasis Discrimination With Biliary Scintigraphy Combined With Ultrasound

摘要: Biliary scintigraphy and ultrasound imaging were performed in 52 patients with suspected biliary tract pathology. Results correlated the findings of direct cholangiography. Several new innovations scintigraphic technique used. The combination correctly identified obstruction 17 19 patients, 12 whom had dilated bile ducts on ultrasonography. Intrahepatic cholestasis was diagnosed 11 13 patients. Accurate discrimination between intrahepatic extrahepatic achieved 28 32 (88%) combined studies. Scintigraphy also provided a correct diagnosis acute cholecystitis all 9 surgically confirmed disease. Eleven additional gallbladder or pancreatic disease normal at scintigraphy, which When imaging, modern can (a) provide excellent (b) help determine need for subsequent invasive diagnostic studies selected
