Radiofrequency ablation in a porcine liver model: Effects of transcatheter arterial embolization with iodized oil on ablation time, maximum output, and coagulation diameter as well as angiographic characteristics

Table 1 Ablation protocol

Baselinepower output	Step up rate	Maximum output	Restart output	Application process
30 W	10 W/min	Until roll-off	70% of the maximum output	Twice

The baseline power output was set at 30 W. Ablation was continued with an increase of 10 W per minute until roll-off occurred. After the first RO, ablation was resumed 30 s later at 70% of the maximum power achieved, and was completed when RO occurred a second time.
