CT在肺癌射频消融治疗中应用价值的评估(附12例报告)

Evaluation of CT in percutaneous radiofrequency ablation( RFA ) of the lung cancer(report of 12 cases)

目的 :探讨CT在肺癌射频消融治疗中的应用价值。方法 :12例肺癌 ,在CT导引监测下完成射频消融治疗。治疗后即刻行CT扫描 ,治疗后均于 1～ 3月内行增强CT观察近期疗效。结果 :12例中肿块直径 <5cm者 3例 ,近期满意率为 10 0 % ,肿块直径 >5cm者 9例 ,近期疗效满意率为 6 7%。癌灶射频消融满意的主要CT表现为 :①被治疗部位密度明显减低 ,其内未见结节或条片状强化区 ;②肿块坏死区大小缩小或无明显变化 ;③肿块坏死区周边环绕清晰锐利的强化环。结论 :CT在肺癌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的价值。

Objective:To evaluate the value of CT in radiofrequency ablation (RFA) of lung cancer.Methods:12 cases of lung cancer were treated by CT guided percutaneous RFA.AII the patients were performed the enhanced CT scanning in 1～3 months after RFA to observe the short term curative effect.Results:In 3 cases with the lesion's size of <5cm (in diameter) the short term satisfactory rate of RFA was 100% and in 9 cases with the lesion's size of >5cm the short term satistactory rate of RFA was 67%.The main CT findings of ablated lesion:①The lesion's density was descended obviously even lesion was liquefied and was no enhanced;②The lesion's size was reduced or no changed;③The lesion may show a sharp marginal enhancement on enhanced CT scan.Conclusion:CT Possess high value in RFA of lung cancer.
