Intraarterial chemotherapy or chemoembolization for locally advanced and/or recurrent hepatic tumors: evaluation of the feeding artery with an interventional CT system.

Purpose: To evaluate the utility of an interventional CT system for intraarterial chemotherapy or chemoembolization for locally advanced and/or recurrent hepatic tumors.

Methods: Thirty-eight patients with locally advanced or recurrent hepatic tumors underwent 73 intraarterial contrast-enhanced CT (IA-CECT) examinations immediately before chemotherapy or chemoembolization. The degree of tumor vascularity on angiography and enhancement on IA-CECT was classified into three grades: no, mild, or marked vascularity.
