Relationship between the amount of ethanol injected and the volume of coagulated necrosis or the energy requirement for inducing per unit volume of coagulated necrosis in PEI-RFA. PEI-RFA was performed on 60 patients with HCC. The ablation was done by using the Cool-tip RF system. The amount of ethanol injected into tumors positively correlated with the volume of coagulated necrosis (A: r = 0.71, P<0.0001) and it negatively correlated with the energy requirement for inducing per unit volume of coagulated necrosis (B: r = -0.41, 0.014).
