  		Fig. 6B —64-year-old man with hepatocellular carcinoma; concordant case with insufficient ablative margin. Arterial phase CT scan obtained immediately after radiofrequency ablation shows nonenhancing ablation zone covering index tumor. However, ablative margin over index tumor posteriorly (arrow) is insufficient.

  		Fig. 6C —64-year-old man with hepatocellular carcinoma; concordant case with insufficient ablative margin. Arterial phase follow-up CT scan obtained 4 months after radiofrequency ablation shows extrazonal peripheral nodular type of local tumor progression at exact site of insufficient ablative margin (arrow).

  		Fig. 7 —64-year-old man with hepatocellular carcinoma after radiofrequency ablation; disconcordant case with contiguous vessel but concordant case with liver capsule. Arterial phase CT scan obtained 1 month after radiofrequency ablation shows extrazonal peripheral nodular type of local tumor progression (arrow) located at different site of contiguous vessel but located at subcapsular region.
