Intravenous cholangiography and cholescintigraphy in the diagnosis of hepatobiliary disease.
The diagnostic yields of intravenous cholangiography (IVC) and 99mTc-diethyl-IDA cholescintigraphy (CS) were compared in 50 patients; 19 had acute cholecystitis, 5 pancreatitis, 4 obstructive disease of the common bile duct, 5 chronic gallbladder disease, 6 parenchymal liver disease and 11 had other intra-abdominal diseases. The comparison of IVC and CS covered three aspects: the definition of the biliary tract structures, their morphologic changes and an assessment of bile flow through the cystic duct and the common bile duct. The definition of the main intrahepatic bile ducts was better with IVC; that of the common bile duct and the gallbladder was better with CS. Morphologic details such as calculi or local changes in duct calibre were detected only in IVC. Measurements of common bile duct calibre obtained from operative cholangiograms correlated better with those from the IVCs than with those from the CSs. CS was more sensitive in the diagnosis of cystic duct obstruction. Bile flow in the common bile duct was estimated in the cases where the gallbladder did not fill. Delayed emptying of the common bile duct was revealed in IVC in 1 and in CS in 3 out of 6 cases with disturbed bile flow. The morphologic findings in IVC gave indication of the obstructive condition in the 1 case with retarded flow and in 2 additional cases. CS provided functional information for which the concentration of the tracer was sufficient except in one case. IVC provided morphologic and functional information, but the excretion of the contrast medium was insufficient for a morphologic assessment of the common bile duct in 16 cases and for a functional assessment in 11 cases.
