Abstract
The aim of this study is to analyze the dynamic CT findings after radiofrequency (RF)
ablation for hypervascular hepatocellular carcinoma (HCC). RF ablation was used for
22 tumors in 20 patients. Peripheral enhancement was noted in 89% of regions within
1 month in the arterial phase. In 1–3 months, peripheral enhancement remained at 56%
and was reduced to 22% by 3–6 months. It is difficult to determine the therapeutic
result within 3 months due to continued peripheral enhancement in the arterial phase.
