螺旋CT的应用为胃肠道病变检查增添了新的手段。这种手段能否清晰、准确、立体直观地显示胃壁、胃腔结构,对比剂的选择非常重要。对胃CT检查前的准备、对比剂的选择,进行分组对比研究,以找出理想方法。在患者条件许可的情况下,使用口服发泡剂产气使胃充盈,能更清楚显示胃壁、胃腔结构及扫描后处理进行MPR重建,从多角度、多方向、立体直观地观察病变有利于病变的检出,尤其适用于仿真内窥镜成像技术。
The application of spiral CT adds new tools for the examination of gastrointestinal lesions. This approach can be clear, accurate, three-dimensional visual display of the gastric wall, gastric structure, the choice of contrast agent is very important. The preparation of the stomach before the CT examination, the choice of contrast agent, the group comparative study to find the ideal method. In patients with conditions permit, the use of oral foaming agent gas filling the stomach can be more clearly show the stomach wall, gastric cavity structure and post-scan reconstruction of MPR, from multiple angles, multi-directional, three-dimensional visual observation of lesions is conducive Detection of lesions, especially for simulation of endoscopic imaging.
