[Sonographic study of the liver, gallbladder and bile ducts].

Most diseases of the liver and gallbladder can be sufficiently diagnosed by ultrasound. Therefore, other useless methods can be eliminated and the further procedure of examination is a lot faster and more specific. Ultrasound cannot only give you exact informations about liver-size, consistency and shape, also structural changes of the liver parenchyma and all 3 tubular systems (bile-duct, liver veins and portal vein) can be examined. So far, no other method provided such a great deal of information about the liver-gall-system with such little effort. Therefore ultrasound should be used as the first screening method for all abdominal problems.
