目的 探讨动静脉期CT扫描联合 诊断右肺上叶肺癌及纵隔淋巴结转移的价 值。方法 回顾性分析2014年5月至2016 年3月在本院进行影像检查并经手术病理 确认的60例肺癌患者的临床资料和影像 资料，同时对肿瘤的类型、强化程度及 转移情况等病理特征进行归类分析。结 果 CT扫描结果显示：总确诊断率91.7%。 各类型肺癌检查结果为：鳞癌型93.3%； 腺癌型90%；小细胞癌93.3%，鳞腺混合癌 90%。肺癌纵隔淋巴结转移确认率为90%。 结论 采用动静脉期CT扫描联合诊断右肺 上叶肺癌及纵隔淋巴结转移临床疗效好， 值得进一步推广和应用。

Objective To make a research on the value of CT dual-phase scanning in the diagnosis of lung cancer with mediastinal lymph node metastasis (MLNM) in right upper lobe. Methods To analyze the CT images of 60 patients with lung cancer identified by surgery from May 2014 to March 2016 in our hospital. At the same time, the types of tumor, the degree of enhancement and mediastinal lymph node metastasis were classified and analyzed. Results The results of analysis showed the total diagnostic rate was 91.7%. And the pathological types were as follows: the index of the squamous cell carcinoma is 93.3%, adenocarcinoma: 90%, small cell carcinoma: 93.3% and squamous adenocarcinoma: 90%. MLNM of lung cancer was confirmed as 90%. Conclusion The clinical effect of of CT dual-phase scanning in the diagnosis of lung cancer with MLNM is worthy to be further applied.
