摘要
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: For studying gastric carcinoma by CT, it is fundamental to recognize correctly the CT anatomy and appearences of normal stomach, to establish the criterion of normal thickness of the gastric wall.Materials and Methods:For this reason, we carried out a series studies of applied anatomy of normal stomach using a stomach phantom and resected or integrated fresh specimen, special gastric CT scanning was done and the thickness of gastric wall was measured in 80 normal adult, after different amount of water drunken, with or without hypotonic injection.Results:The axial CT imagings could display clearly anatomic sections, anterior walls and posterior, greater and lesser curvature of stomach, and relationship with adjacent organs. The thickness of normal adult stomach related primarily with amount of water filled, and was <3～5mm but variable in different regions if water filling optimal.Conclusion: The thickness of the wall of optimaly dilated stomach >5mm was considered abnormal. Anatomic structure and sections of stomach could be demonstrated. Accoding to the clinical , we think that the three devision method of stomach should be used by CT to study stomach.
