目的：研究胃壁厚度与口服对比剂量之间的关系。材料和方法：通过三组６５ 例服用不同量对比剂者胃壁厚度的测量和研究，胃标本扫描模拟胃气液面征现象。结果：表明增强扫描胃扩张良好时胃壁呈均一性增强，中等度扩张时胃内常见到较多的粘膜皱襞，胃扩张不充分时胃襞明显增厚并可显示多层结构。结论：认为测量胃壁厚度时应使胃处于良好的扩张状态。胃扩张不充分时部分病例显示胃气液面征。
Aims: To investigate the relationship between gastric wall thickness and oral contrast dose. MATERIALS AND METHODS: The stomach specimens were scanned to simulate gastric gas-liquid surface signs by measuring and investigating the gastric wall thickness in 65 patients taking different doses of contrast agent. Results: The results showed that the stomach wall was enhanced homogeneously with enhanced gastric dilatation, more mucosal folds were found in the stomach when moderately dilated, and the stomach pouch was obviously thickened and showed multi-layered structure when the stomach dilated. Conclusions: It is believed that the stomach should be in good dilatation when measuring the thickness of the stomach wall. Inadequate gastric dilation in some cases showed gastric gas liquid signs.
