[Serial CT of liver - possibilities and limitations (author's transl)]

Dynamic computerized tomography (angio-CT or serial CT) has established itself quickly as complementary method to non-invasive liver examination methods. The article describes the requisite apparatus and examination method as well as the possibilities of evaluating the data obtained. Indication for serial CT should be critically assessed. The possibilities and limitations in interpreting local and time differences in the kinetics of the contrast medium bolus are demonstrated. In individual cases, serial CT offers valuable aid for the discovery of pathological findings at the large vessels and for differential diagnosis of focal liver lesions. On the other hand, it has gained little significance so far in diagnosing diffuse diseases of the liver parenchyma.
