目 的 探讨增强多层螺旋 CT(MSCT)在判断肺癌手术可切除性中的 应用价值。方法 回顾性分析2014年8 月-2016年8月我院经手术或活检病理确诊 的68例非小细胞肺癌(NSCLC)患者的增强 MSCT影像资料，并与手术结果对照。结 果 增强MSCT评估肺门、纵膈大血管受侵 犯及膈淋巴结转移与手术结果的一致性 分别为86.76%、83.82%，一致性比较满 意(Kappa=0.68、0.61)，敏感度分别为 77.78%、80.0%，特异度分别为90.0%、 86.05%。增强MSCT评估NSCLC可切除性与 手术结果的一致性为79.41%，一致性比较 满意(Kappa=0.57)，敏感度为85.37%，特 异度为70.37%。结论 增强MSCT可反映血 管受侵犯、纵膈淋巴结转移情况，为胸 外科医师判断NSCLC可切除性提供客观资 料。

Objective To investigate the application value of contrast-enhanced multislice spiral CT (MSCT) in judging the feasibility of excision of lung cancer. Methods The contrast-enhanced MSCT images of 68 patients with non-small cell lung cancer (NSCLC) diagnosed by operation or biopsy in our hospital from August 2014 to August 2016 in were retrospectively analyzed and were compared with results of operation. Results The coincidence rates of contrast-enhanced MSCT in evaluating pulmonary hilar and mediastinal great vessel invasion and mediastinal lymph node metastasis with the results of operation were 86.76% and 83.82%, the consistency was satisfying (Kappa=0.68, 0.61), the sensitivities were 77.78% and 80% respectively, the specificities were 90% and 86.05% respectively. The coincidence rate of contrast- enhanced MSCT in evaluating feasibility of excision of NSCLC with the results of operation was 79.41%, the consistency was satisfying (Kappa=0.57), sensitivity was 85.37%, and specificity was 70.37%. Conclusion Contrast-enhanced MSCT can reflect the invasion of blood vessels and mediastinal lymph node metastasis, providing objective data for the doctors to judge the resectability of NSCLC.
