摘　　要：目的研究正常胃的螺旋CT表现及熟悉扫描技术的应用。方法应用螺旋CT扫描技术对60例正常成人进行胃区扫描,48例行增强扫描。结果按充盈程度不同胃壁形态分为3型,其中扩张不良型(8),适度扩张型(35),充分扩张型(17)。测量52例并计算出各区胃壁厚度的正常值,分别为贲门区:(5.96+1.47)mm,胃底区:(3.68+1.08)mm,胃体区前后壁:(3.78+1.17)mm和(3.44+1.28)mm,胃窦区前后壁:(4.92+0.96)mm和(4.48+0.71)mm。结论应用螺旋CT扫描技术能获得满意的正常胃的图像及胃壁厚度的测量,较好地显示胃及与邻近结构的解剖关系。Objective The purpose of this study is to evaluate the value of spiral CT imaging in normal stomach. Methods A study of 60 adults( with no gastric disease) underwent spiral scans. All adults were scanned with spiral CT and 48 adults underwent contrast within one breathhold each. Results According to the filling degree of stomach,the shape of the wall of stomach was classified into three types: insufficient distention( 8),proper distention( 35) and full distention( 17). In stomachs of all adults,the subareas could be scanned,gastric thickness of different areas could be measured. Spiral CT can get well in detecting gastric structure. Conclusion Spiral CT could not only scan subarea from more planes and angles,but also be used in measuring gastric thickness of different districts. It can well display the anatomic relationship between the stomach and its adjacent organs.
