摘　　要：目的　应用螺旋CT评价射频治疗肺部恶性肿瘤的近期疗效。方法　对 40例肺癌 43个病灶射频治疗前、后肿瘤大小、密度的变化、肿瘤凝固性坏死的形态、范围及并发症进行观察。结果　 40例肺癌射频治疗后 5min90 .69% (3 9/ 43 )的肺癌病灶扩大 ,6.9% (3 / 43 )病灶大小无变化 ,2 .3 % (1/ 43 )病灶缩小。 97.67% (4 2 / 43 )病灶密度减低 ,2 .3 % (1/ 43 )病灶密度增高。术后 2 0例肺癌随访 1～ 17个月 ,平均随访 4.3个月 ,5 5 % (11/ 2 0 )病灶较原病灶缩小 ,40 % (8/ 2 0 )病灶较术前增大 ,5 % (1/ 2 0 )病灶大小无变化 ,95 % (19/ 2 0 )肿瘤密度减低 ,CT值平均减低 13Hu ,5 %(1/ 2 0 )密度增高。结论　螺旋CT可准确评价肺癌射频治疗的效果 ,为临床治疗提供依据。Objective To evaluate short-term therapeutic effect of lung neoplasm after radio frequency ablation using spiral CT. Methods CT scan were performed forty-three lesions in 40 cases with lung neoplasm to investigate the alterations of tumor size and density pre-and post-procedure, the from and size of coagulative necrosis and complications. Result The size of thirty-nine lesions in 40 cases with lung neoplasm was increased 5min after the procedure(90.69%), three lesions was no change(6.9%),one lesion was decreased(2.3%).The density of 42 lesions was lowered(97.67%) and 1 lesion is increased(2.3%).The follow-up was taken place after 1-17 moths after the procedure(the average 4.3 moths),the size of 11 cases(55%) was decreased, 8 cases (40%) was increased, 1 cases(5%) showed no change.The lowered densities were showed in 19 cases (95%))(the average CT value is lower 13Hu than before the procedure),the increased densities were showed in 1 case(5%). Conclusion Spiral CT scan is an useful method to assess the effect of radio frequency ablation and provide information of objective parameters and prediction of prognosis.
