目的 探讨胃癌患者多层CT征象 与病理TN分期及CT-TN分期的关系。方法 回顾性分析我院2014年2月-2016年2月期 间接收并治疗的27例胃癌患者的CT检查 资料，并对胃癌患者的肿瘤特征、TN分 期、CT征象以CT-TN分期的关系进行综合 分析。结果 多层CT扫描诊断出胃癌T1患 者8例，T2患者13例，T3患者5例，T1患者 1例，T分期的符合率为87.08％。诊断为 N1期患者17例，N2期患者9例，N3期患者1 例，N分期的符合率为91.35％。结论 胃 癌的多层CT平扫结合增强扫描征象与病理 TN分期具有统计学意义上的相关性，CT征 象能够较为准确地判断胃癌侵犯的深度， 对胃癌 TN 分期诊断具有较高的准确性。 对于临床手术方案和治疗方案的制定具有 十分积极的作用，建议在临床上进一步推 广。

Objective To analyze the correlation between multi-slice CT characters and gastric cancer TN staging and the relationship of CT-TN staging. Methods Retrospective analysis of clinical and MSCT data of 27 patients with gastric cancer in our hospital from February 2014 to February 2016, and comprehensive analysis of tumor characteristics, TN staging, CT Imaging and relationship of CT-TN staging. Results With MSCT scan in diagnosis, among 27 gastric cancer patients, there are 8 patients in T1, 13 patients in T2, 5 patients in T3 and 1 patient in T4, the accuracy of T staging is 87.08%. There are 17 patients in N1, 9 patients in N2 and 1 patient in N3, the accuracy of N staging is 91.35%. Conclusion The characteristics of MSCT scan combined with enhanced scanning has statistical correlation with TN staging of gastric cancer, which can accurately determine the depth of invasion of gastric cancer, and has high accuracy on TN staging diagnosis of gastric cancer. So MSCT has positive effect on clinical surgery and treatment programs, which is worthy of clinical application.
