title: [Determining the value of ultrasound in diagnosis of the gallbladder and bile ducts].
abstract: The status and application of diagnostic methods are not only determined by their efficiency; the radiation exposure, the grade of invasivity and the costs involved are also decisive facts. Under consideration of all these aspects, ultrasound has gained acceptance as the method of first choice in the diagnostic of diseases of the gallbladder and the biliary tract. Inflammatory biliary diseases as well as gallstones are domains which are exclusively controlled by ultrasound. Since there is currently no system available for the early recognition of gallbladder carcinomas, sonography is likely to become a forerunner in this field. The biliary tract with its tubular structure, however, is rather difficult to visualize and interpret with sonography, hence additional examinations often have to be performed.
