摘　　要：目的:评价低张动态增强多排螺旋CT对胃癌TNM分期的价值。方法:收集76例胃癌患者行螺旋CT检查,结合多平面重建(MPR)、CT仿真胃镜(CTVG)及表面遮盖显示(SSD)等后处理技术进行分期,以探讨多排螺旋CT对胃癌术前分期的价值。结果:72例患者中T分期总的准确率为69.4%。N分期的准确率为71.1%。M分期的准确率为90.8%。结论:低张增强多排螺旋CT确能提高术前TNM分期的准确性,但N分期中淋巴结大小与转移的关系,仍需进一步研究。Objective To define the value of the multislice spiral CT(MSCT) in the staging of gastric carcinoma through oral gas contrast medium and contrast enhancement scan. Methods Seventy-six cases of gastric cancer, all of whom were proved by post-operative pathology were examined by MSCT before operation. Results The accuracy of MSCT in 72 patients was 69.44% for T staging, 71.05% for N staging and 90.79% for M staging. Conclusions MSCT can elevate the accuracy in the preoperative TNM staging; however, the relationship between the lymph nodes size and the metastasis should be further studied.
