摘　　要：上腹部CT检查,常规口服造影剂,以便区别胃肠道与肿块的界线,或确定胃肠本身肿瘤的部位,范围。我院在1989年底前服用1％稀释碘剂,1990年始服用淡水为胃肠造影剂。作者随机抽取每组100例病例进行比较,将显示胃粘膜,胃壁,胃充盈程度及伪影多少各分三级为观察指标。双盲法统计,经x^2检验,证明两者相差显著P<0.05。认为水有如下优点:①来源方便,无密度差别,与其它造影剂比较(如碘剂)更接近于生理成份;②无异味,无过敏反应,病人易接受;③可清楚显示胃各部粘膜,胃壁厚度,特别是增强后更为满意;④伪影少。认为上腹部CT检查服淡水做胃肠造影剂是值得推荐的好方法。Iodine—containing contrast medium is used as a routine in CT examination of the upper abdomen to visualize the gastrointestinal tract and delineate the pancreas and masses nearby. In order to improve image quality in CT examination of upper abdomen we employed plain water as contrast medium and compared the results with that of iodine—containing media in IOO cases respectively. The results showed that there was significant difference between them by statistic (X^2test, p<0.05). We also found plain water was better for acceptable by more patients, easier to obtain, tasteless, no hypersensitive reaction, no arti— fact and no overlapping effect. The authors recommand plain water as contrast medium instead of iodine—containing contrast medium in upper abdomen CT examination.
