[Sonography in the Diagnosis of Intrahepatic Cholangiectasis (author's transl)]

The sonographic pattern of signs associated with cholangiectasis is analysed in 25 patients. The extent of dilatation of the bile ducts correlates with the bilirubin level and the duration of the disease. Discrepancies occur in fibrose processes in the biliary tract region and in localised cholangiectases. Sonography is a basic radiologic examination method if there is any suspicion of obstruction to flow in the biliary tract. Findings obtained via sonography are the starting-point of further examinations.
