title: Single bolus versus drip infusion for intravenous cholangiography.
abstract: Biliary tract visualisation in 50 patients examined by infusion of methylglucamine iodipamide was compared, by double-blind technique, to cholangiograms obtained in 50 other patients by a single bolus injection. The infusion technique did not give better results than the single bolus method. In another group of 20 patients, each individual was examined by both methods. The radiographs, read in a double-blind manner, showed both methods to be comparable in demonstrating the biliary system. It seems that other means have to be designed and employed in order to improve the radiographic delineation of the biliary tract.
