[Arterial angio-CT and magnetic resonance tomography of Klatskin tumors].

Abstract

The knowledge of the exact spreading and location of a malignant bile duct tumor and the exclusion of differential diagnoses are the prior conditions for the development of an optimal therapy concept. All usual methods such as ERCP, PTC, ultrasound, CT and angiography have weak points in the diagnosis of Klatskin tumors. A new aspect for the solution of this problem is the ability to visualize these tumors by arterial angio-CT and MR.
