The average maximum diameter of the lesion was 1.26 \u00b1 0.65 (0.50-2.58)cm.

The center of the ablated zones showed a short T1 and short T2 signals with the ring-like of long T1 and long T2 signals surrounded after immediately evaluation. No serious complications occurred. The average follow-up period was 12.89 \u00b1 4.33 (2.0-19.6) months.
