[The value of CT in the evaluation of bile ducts and gallbladder (author's transl)].

Initially, the history of radiographic diagnosis of the gallbladder is reviewed. Then, examples are given to demonstrate morphology and topography of a normally and an abnormally developed gallbladder. Then, CT findings of pathology of the biliary system are demonstrated, such as calculi, inflammation, hydrops and neoplasia. A postulation is made that not only should CT be used in cholestasis but also in a nonvisulized cholecystrogram. The value and the limitations of CT are pointed out, as well as the necessity to always include the evaluation of bile ducts and gallbladder in the analysis of obscure clinical upper abdominal findings.
