摘要
目的研究多层螺旋CT影像技术在胃癌术前分期中的应用价值。方法将62例已确认为胃癌患者作为研究对象,首先分别进行多层螺旋CT平扫和动态增强扫描,再进行CT仿真胃镜以及基于容积再现、多平面重建、表面遮盖显像与透明显像的三维显像。最后根据国际抗癌联盟标准,对所有胃癌患者分别进行胃癌TNM分期,并将其与患者手术病理结果进行对比分析。结果 CT仿真胃镜结合三维显像对胃癌患者术前T、N、M以及TNM临床分期的准确率分别为76.3%、80.0%、95.8%与80.6%,对胃癌大体分型判断准确率为83.3%。且在胃癌术前TNM分期上,多层螺旋CT与术后病理结果一致性较高。结论多层螺旋CT影像技术胃癌术前分期具有较大的临床应用价值,对胃癌患者的个体化治疗有重要指导意义。
Objective Investigate the application value of multi-slice spiral CT imaging in the preoperative staging gastric cancer.Methods Take 38 cases have been confirmed in patients with gastric cancer as the research object. First of all, they were carried out in the multi slice spiral CT scan and dynamic enhanced scanning, and then CT simulation was carried out on the basis of the three-dimensional imaging of the gastroscopy and volume rendering, multi planar reconstruction, surface covering and transparent imaging. Finally, according to the International League against cancer standards, all patients with gastric cancer were TNM stage, and the results were compared with the surgical pathology. Results The accuracy of T, N, M, TNM and CT were 76.3%, 80.0%, 95.8% and 80.6% respectively in the clinical staging of gastric cancer patients. The accurate rate of spiral CT in gastric cancer was 83.3%. And in the preoperative TNM staging of gastric cancer, the multi slice spiral CT has a high consistency with the postoperative pathological results. Conclusion Multi-slice spiral CT imaging technology has great clinical application value in the preoperative staging of gastric cancer, and it has important guiding significance for the individual treatment of patients with gastric cancer.
