| Research Abstract |
From 2008 to 2010, thirty five tumors in 30 patients that show no local progression for more than 2 years were included in this study. In CT images, the size of ablation zone decreased after 3 or 6 months after radiofrequency ablation (RFA) compared to 1 month after the procedure. On the other hand, the accumulation of FDG in PET scan obtained 3 months after RFA, showed no significant difference compared to the pre-treatment image, but significant decrease after 6 months after the treatment. In conclusion, it is eligible that FDG-PET was performed 6 months than 3 months after RFA.
