Fig. 2. Computed tomography (CT) images of a 49-year-old woman who underwent radiofrequency ablation (RFA) for a medium-sized hepatocellular carcinoma (HCC) using an ICW electrode with a 3-cm active tip. (A) The arterial phase axial CT image 7 days prior to RFA shows a 3.3-cm diameter HCC between hepatic segments V?VIII (arrow). (B) The portal venous phase axial CT image and (C) coronal CT image 1.5 hours after RFA show the ablation zone (arrows). The calculated volume of the ablation zone is 57.0 cm³.
