Utility of C-Arm CT in Detection of Hepatocellular Carcinoma During Trans Arterial Chemoembolization

Abstract

ranscatheter arterial chemoembolization is one of the effective therapeutic options for hepatocellular carcinoma (HCC). Ultraselective chemoembolization is an alternative approach to improve local control, and is associated with a reduced incidence of adverse effects. Identification of a tumor and its feeding branch is an important factor when performing effective chemoembolization, as well as selective catheterization into the tumor-feeding branch. Because of The high spatial resolution of cone beam CT (CBCT) using a flat panel and three dimensional (3D) angiography has been increasingly used to delineate occult liver tumors and to identify intrahepatic or extrahepatic arterial supply to a tumor with a performance comparable to CT angiography.
