Liver perfusion with dynamic multidetector-row computed tomography as an objective method to evaluate the efficacy of chemotherapy in patients with colorectal cancer.

A total of 24 liver metastases of colorectal cancer were evaluated by dynamic multiphasic CT. Under chemotherapy, follow-up examinations were performed every 3 months. The tumor marker CEA before vs.

[Impact of a guiding CT prior to angiographic intervention].

With these two cases we want to demonstrate the additional impact of contrast enhanced multi-detector-row-CT angiography (MDR-CTA) compared to digital subtraction angiography (DSA) for planning of angiographic intervention. In selected cases a pre-interventional CTA can be useful to facilitate angiographic intervention. We selected two patients with different disease entities (bleeding caused by hepatic aneurysmosis; hepatocellular carcinoma (HCC) prior to transarterial chemoembolization (TACE) with aberrant arteries) from our collective who underwent CTA prior to angiographic intervention.
