目的 探讨在胃癌腹腔镜根治术 及胃癌介入治疗中多层螺旋CT(multislice spiral CT，MSCT)针对胃周动静 脉血管成像的应用价值。方法 搜集在 我院80例经病理证实的胃癌患者，治疗 前均使用飞利浦256层iCT进行腹部三期 增强扫描后，将原始数据重建薄层后传 至飞利浦后处理工作站，使用后处理程 序容积演示(volume rendering,VR)、 曲 面 重 建 技 术 ( c u r v e d p l a n a r reformation,CPR)、薄层最大密度投影 法(maximum intensity projectionthin, MIP-Thin)、最大密度投影法 (maximum intensity projection, MIP) 显示胃及及肿瘤供血血管。结果 采用 VR、CRP、MIP-Thin、MIP重建技术，可 以对胃主要动脉血管起源、走行及变异 的情况进行显示分析，但动脉远端细小 血管及静脉显示较差。结论 MSCT对胃及 肿瘤血管成像技术，可以为临床腹腔镜 及介入治疗胃癌提供重要信息。

Objective To study the arteriovenous imaging value of multi-slice spiral CT in the laparoscopic and interventional treatment for gastric cancer. Methods To collect 80 patients with gastric cancer, which were confirmed by pathology in our hospital. abdominal three phases enhanced scan was performed by Philips 256 layer iCT before treatment, the imaging data was sended to post-processing workstation, volume rendering (VR), curved planar reformation(CPR), maximum intensity projection-thin(MIP-Thin), maximum intensity projection(MIP) was used to show stomach and tumor blood vessels by post-processing program. Results Using VR, CRP, MIP-Thin, MIP reconstruction technology, can show the beginning, path and mutation of stomach major blood vessels, but distal small blood vessels is poor to display. Conclusion MSCT of stomach and tumor vascular imaging technology, can provide important information for clinical in laparoscopic and interventional treatment gastric cancer.
