title: [Intra-arterial dynamic computed tomography in characterizing liver metastases of colorectal cancer].
abstract: Locoregional chemotherapy of liver metastases from colorectal tumours is a promising new approach. The results of CT in fifteen patients after intravenous and intra-arterial contrast injection are compared. The liver metastases are supplied mainly by the arterial route and this permits a means of assessing therapy. Contrast injections through a hepatic catheter may result in flow phenomena which limits the value of this investigation. It is unknown whether such flow phenomena may influence the result of intra-arterial chemotherapy. Although the margins of the metastases were more clearly defined, diagnostic accuracy was not increased, as compared with intravenous CT enhancement.
