[Kinetics of the biliary system (author's transl)].

A dynamic study of the hepato-biliary system was carried out by means of HIDA-99mTc and of a gamma-camera. The study was performed in basal conditions and after administration of a fatty meal. Normal subjects and patients suffering from various diseases of the biliary system were examined. The method is simple and well tolerated. Three mechanisms are invoked and discussed concerning the kinetic reactions of the gall bladder and the biliary ducts.
