目的 探究16排螺旋CT在周围型 肺癌临床诊断中的研究价值。方法 对我 院2008年-2015年这7年间的周围型肺癌 患者65例进行回顾性分析，由我院放射 科3位资历丰富的诊断医生在不知任何病 理结果情况下对65例患者CT图像进行阅 片，对照65例肺癌患者在本院病理检查 的报告，在对65例患者病灶对应的影像 特征进行对照分析，数据均采用专业软 件进行分析。结果 65例患者中在CT扫描 中胸膜凹陷征、血管集束征和纵膈淋巴 结转移特征在病理学检查和肺癌发生具 体情况存在明显差异；低分化型、中等 分化型和高分化型的统计数据中胸膜凹 陷征、血管集束征和纵膈淋巴结转移产 生状况存在明显的差异性，具有统计学 意义。结论 胸膜凹陷征、血管集束征和 纵膈淋巴结转移在病理学检查和肺癌发 生具体情况存在明显差异，仍需进一步 分析，所以16排螺旋CT在周围型肺癌临 床诊断中具有一定的研究价值。

Objective To investigate the research value of spiral CT on clinical diagnosis of peripheral lung cancer. Methods 65 cases with peripheral lung cancer in our hospital from 2008 to July 2015 were selected and retrospectively analyzed. CT imaging of 65 patients were analyzed by 3 diagnostician, data were analyzed by professional software. Results In CT scan, pleural indentation, vascularnotch sign, mediastinal lymph node metastasis of 65 patients had obvious difference on pathological examination; In statistical data of poorlydifferentiated, moderately-differentiated, highly-differentiated, pleural indentation, vascularnotch sign, mediastinal lymph node metastasis had obvious difference, the difference was statistically significant. Conclusion Pleural indentation, vascularnotch sign, mediastinal lymph node metastasis have obvious difference on pathological examination and need further analysis. 16-slice spiral CT has certain research value on clinical diagnosis of peripheral lung cancer.
