Dynamic CT of Malignant Liver Tumors and Liver Transplants

Abstract

Contrast medium supported computed tomography has proved itself in the diagnostics of liver tumors. The high specificity and sensitivity of this method has been demonstrated in such benign focal masses as hemangiomas or focal nodular hy-perplasias (FNH). However, malignant tumors of the liver are more difficult to differentiate because of only slight distinctions in contrast medium behavior. One reason for constantly improving liver transplantations is the timely diagnosis of postoperative complications. Follow-up controls after liver transplantation should not, if possible, be invasive and should demonstrate complications early to allow the initiation of sufficient therapeutic measures.
