Imaging evaluation after radiofrequency ablation of lung malignancy -CT, MRI, and FDG-PET-

从2008年到2010年，30名患者的35个肿瘤超过2年未显示局部进展，被纳入本研究。在CT图像中，与术后1个月相比，射频消融（RFA）后3个月或6个月的消融区尺寸减小。另一方面，在RFA后3个月获得的PET扫描中的FDG累积与治疗前图像相比没有显著差异，但在治疗后6个月后显著降低。总之，RFA后6个月而不是3个月进行FDG-PET是合格的。

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.
