The Measured Value of the RF-induced Ablation Zones and the Tissue Temperature According to the RF Power Application Modes

Note.-Dl: long-axis diameter, Dv: vertical diameter, Ds: short-axis diameter.

^*The consecutive mode generated three separate ablation spheres; therefore, the volume of each RFA zone was calculated, respectively, and then summed up. In addition, the three diameters (Dl, Ds, and Dv) of the ablation zone were measured from the biggest one among the three separated ablation areas. ^†There was a significant difference between the consecutive and simultaneous modes and between the consecutive and multipolar modes, ^‡There was a significant difference in each group, ^§There was a significant difference between the consecutive and multipolar modes and between the simultaneous and multipolar modes, ^∥There was a significant difference between the consecutive and simultaneous modes and between the simultaneous and multipolar modes.
