目的：正确认识胃的ＣＴ解剖和表现，了解正常成人的胃壁厚度，确立正常和异常的标准。材料与方法：我们用胃模型、离体和在体标本进行了正常胃ＣＴ应用解剖的研究，对３组共８０例正常成人服用不同量的水行或不行低张药注射后进行ＣＴ扫描和测量胃壁厚度及值检验。结果：横断面ＣＴ图可以清楚的显示胃的解剖区域、前后壁和大小弯等，尤其与邻近器官的毗邻关系非常清楚。正常成人胃壁厚度与服水量及胃的扩张程度关系密切，在不同部位，其厚度也不一致。在胃良好充盈下，正常人胃壁厚度＜３～５ｍｍ。探讨了各种因素对胃壁厚度的影响。结论：我们认为在胃良好充盈下，胃壁厚度＞５ｍｍ为异常。ＣＴ能清楚的显示胃的解剖区域，结合临床实际，我们主张采用胃的三分区法。
Objective: Correct understanding of the CT anatomy and performance of the stomach to understand the normal adult gastric wall thickness, the establishment of normal and abnormal standards. Materials and Methods: We used the gastric model, in vitro and in vivo specimens of normal stomach CT anatomy study, a total of 80 normal adults in three groups taking different amounts of water or no hypoxemic injection after CT scan and Measurement of gastric wall thickness and value test. Results: The cross-sectional CT images clearly showed anatomical regions of the stomach, anterior and posterior wall and the size of the curve, especially the adjacent relationship with adjacent organs is very clear. Normal adult gastric wall thickness and service water and the extent of the expansion of the stomach close, in different parts of its thickness is inconsistent. Good filling in the stomach, the normal stomach wall thickness <3 ~ 5mm. The effects of various factors on the gastric wall thickness were discussed. CONCLUSIONS: We believe that gastric wall thickness> 5 mm is abnormal under good filling of the stomach. CT can clearly show the anatomy of the stomach, combined with clinical practice, we advocate the use of the stomach of the three-zone method.
