Intervention

Procedure:
• Radiofrequency ablation using combined bipolar and monopolar energy deliver with Twin Cooled-Wet electrodes
Radiofrequency ablation will be performed by using twin cooled-wet electrodes. Two electrodes will be places on the tumor under ultrasonography (US)-computed tomography (CT)/magnetic resonance (MR) fusion tool guidance. The electrodes will be cooled with saline, and radiofrequency (RF, bipolar mode and switching monopolar mode) will be applied to two electrodes at the same time for about 6 to 30 minutes depending on the tumor size. The temperature will be maintained at 90-100 °C. The RF energy will be delivered by using the 200 watts single generator.
