摘　　要：目的探讨CT扫描在肺癌射频消融治疗中的应用价值。方法13例肺癌,在CT导引监测下完成射频治疗,治疗后即刻行CT扫描。治疗后均于3个月后行增强CT扫描观察近期疗效。结果13例中肿块直径小于5cm者4例,近期疗效满意率为100%,肿块直径大于5cm者9例,近期疗效满意率为67%。癌灶消融满意的主要CT表现为(1)被治疗部位CT值减低,其内未见结节或条片状强化区。(2)肿块坏死灶与治疗后即时改变相同或缩小。(3)若肿块无明显缩小,强化扫描肿块不显影,其周边环绕强化环。结论CT在射频消融治疗中无论导向定位穿刺、治疗监测和疗效评估都有重要价值。Objective To evaluate the value of CT in radio frequency ablation （RFA） of lung cancer. Methods 13 cases of lung cancer were treated by CT-scanning at least three months after RFA to observe the short - term curative effect. Results In 4 cases with the lesion＇s size smaller than 5cm, the short-term satisfactory rate RFA was 100%. In 9 cases with the lesion＇s size larger than 5 cm, the short-term satisfactory rate of RFA was 67%. The main CT findings of ablated lesion were （ 1 ） The CT due of lesion decreased even lesion was liquefied and was not enhanced; （2） The lesion＇s size was reduced or had no change, （3） If the lesion＇s size was not reduced, the lesion was surrounded by sharp marginal enhancement on enhanced CT scan. Conclusion CT possesses high value in RFA of guiding percutaneous puncture monitoring treatment and evaluating the effect of treatment.
