OBJECTIVE: We assessed whether helical CT hepatic arteriography (CTHA) improves detection of hypervascular hepatocellular carcinoma (HCC) when used in conjunction with helical CT obtained during arterial portography (CTAP). SUBJECTS AND METHODS: One hundred two patients with 254 hypervascular HCC nodules underwent both CTHA and CTAP. CTHA and CTAP were separately interpreted for detection of hypervascular HCC nodules by three observers who were unaware of tumor burden in the liver, lodized oil CT performed 1 week and 1 month after transcatheter arterial chemoembolization with iodized oil was the gold standard. Sensitivity and positive predictive value for CTHA alone, CTAP alone, and CTAP and CTHA combined were calculated and compared using the McNemar test. RESULTS: We found no significant difference between the sensitivity of CTAP (85%) and CTHA (87%) for revealing hypervascular HCC nodules. The combination of CTAP and CTHA showed significantly higher sensitivity than either CTAP or CTHA alone for revealing HCC nodules smaller than 20 mm in diameter (p < .01). CONCLUSION: The combination of CTHA and CTAP is recommended to improve the detection sensitivity of small hypervascular HCC nodules.
