Although cholecystography was introduced by Graham and Cole in 1924,1 until recently there was no simple method of making roentgenologic studies of the bile ducts. Radiopaque materials had to be injected directly into the common duct during or after operation,2 or they were introduced percutaneously under peritoneoscopic visualization.3 The necessity of a method that will give good visualization of the gallbladder and bile ducts without surgery can be well appreciated. Recently such studies have been reported from Germany,4 in which an iodinecontaining substance that is actively excreted by liver cells when injected intravenously is used. The high iodine content of the substance makes it possible to visualize the bile ducts early after injection and the gallbladder later. The concentrating power of the gallbladder is not necessary for visualization as it is with other materials. The German workers5 have reported that, in the absence of parenchymal
