Eight HCC were treated with L-EI-RFA, Nine HCC were treated with T-EI-RFA and five HCC were treated with O-EI-RFA. Location of the tumor, tumor size (T-S), instruments for ablation (Ins), amounts of injected ethanol (EtOH), ablated area (A-A), [longest diameter (L) × shortest diameter (S) × height (H)], volume of coagulated necrosis (V) and volume of marginal coagulated necrosis (M) are shown.
