目的：对口服脂肪密度造影剂后，行上腹部CT扫描的正常人胃体部及贲门部胃壁的形态进行观察并通过测量获得胃壁的正常厚度。材料与方法；受检正常人102例，口服脂肪密度造影剂为15％花生油乳剂，经常规上腹部CT扫描后，观察胃体部及贲门部胃壁形态并进行测量，经统计学处理得出平均值。结果：正常人胃体部壁形态光整，厚度在0．2－1．0cm范围之内，中位数0．35cm，贲门部胃壁较胃体部略厚，呈三角形或折角状，厚度在0．2－1．1cm之间，平均值为0．58cm。结论：正常人胃体部及贲门部胃壁光滑，规整、厚度分别应在1．0cm及1．2cm以下。
OBJECTIVE: To observe the morphology of stomach and stomach in normal human gastric body and cardia by CT scan of the abdomen after oral administration of fat density contrast agent and to obtain the normal thickness of stomach wall by measurement. Materials and Methods; Totally 102 normal subjects were tested, and oral fat density contrast agent was 15% peanut oil emulsion. The abdominal wall CT scanning was performed routinely to observe the gastric wall morphology of stomach body and cardia and measure the average wall thickness value. Results: Normal body part of the body wall smoothing, thickness in the range of 0.2-1.0cm, the median 0.35cm, gastric cardia stomach thicker than the body, triangular or angled, thickness in the 0.2-1.1 cm, with an average of 0.58 cm. Conclusion: Normal gastric body and cardia stomach smooth, regular, the thickness should be 1.0cm and 1.2cm below.
