| ［摘要］ 多层螺旋CT（multi-slice spiral CT,MSCT）对胃癌检查的成像技术日益成熟，多期增强扫描结合多平面重组（multi planner rerformation,MPR）后处理技术能充分显示胃壁多层结构，可以观察到胃壁结构的异常变化，有利于检出胃癌。通过观察胃癌侵犯胃壁深度、淋巴结转移和远处转移情况，对胃癌进行术前TNM分期的评估已成为近年来临床研究的热点，该文就MSCT在胃癌术前诊断中应用的研究进展作一综述。 |

| Abstract: |
| ［Abstract］ The imaging technique of multi-slice spiral CT(MSCT) examination for gastric cancer is becoming more and more mature. Multi-phase enhanced scan with MPR post processing technique can fully display the stomach wall of multilayer structure and show the abnormal changes of gastric wall structure, which is useful in diagnosing gastric cancer. Presently, the preoperative TNM staging evaluation through the observation of gastric cancer invasion depth of gastric wall, lymph node metastasis and distant metastasis of gastric cancer, has become a popular clinical research topic. Applying MSCT for preoperative diagnosis of gastric cancer is reviewed in this paper. |
