Hepatocellular Carcinoma: Are Combined CT during Arterial Portography and CT Hepatic Arteriography in Addition to Triple-Phase Helical CT All Necessary for Preoperative Evaluation?

Abstract

The use of CTAP and CTHA, in addition to being invasive and costly, resulted in an unacceptably high false-positive rate without a substantial increase in sensitivity. Therefore, CTAP and CTHA are not recommended for preoperative evaluation of HCC; THCT alone is preferred.
