Hepatobiliary scintigraphy using Tc-labelled radiophamaceuticals is employed primarily for the diagnosis of acute cholecystitis and for demonstration of biliary tract patency. We conducted a retrospective study of 55 patients with hepatobiliary disease from Jun. '84 to Sep. '84 at Taegu Catholic Hospital and tried to determine the etiology and find the possible differential points by analyzing the scintigraphic findings. The following results were obtained; 1. Tree-like photon defect on hepatic parenchyme was suggested characteristic of complete obstructive biliary disease, but could be seen in either benign or malignant etiology. 2. The grade of hepatocyte clearance was not useful in determining whether the cause of obstructive biliary disease was benign or malignant in this study. 3. Hepatocyte clearance was more severely impaired in hepatocellular disease than in obstructive biliary disease. 4. The photon defect in porta hepatis with complete biliary obstruction was suggest d characteristic of common bile duct concer. 5. The meniscus apperance at obstructed site of common bile duct was pathognomonic sign of choledocholithiasis. 6. When the gallbladder was not visualized, the differential diagnosis between acute and chronic cholecystitis was possible without delayed image by observing the transit time to bowel. The delayed transit to bowel was a favorable of chronic cholecystitis rather than of acute cholecystitis. 7. Acute pancreatitis could be easily differentiated from partial biliary obstruction by clinical and laboratory examination, but the finding of abrupt narrowing of pancreatic common bile duct with slight proximal dilatation on cholescintigraphy was also a key point in acute pancreatitis. 8. The segmental dilatation of intrahepatic duct was thought meaningful sign of clonorchiasis.
