摘　　要：目的:探讨超声造影在胃十二指肠病变筛查中的应用价值。方法:228例体检者行超声造影检查,图像采用3级评判,以胃镜对照,分析图像质量及诊断符合率。结果:图像质量均以Ⅲ级显示为主,食管下段,贲门,胃底,胃体,胃窦,十二指肠球部及降部和水平部Ⅲ级显示比分别为77.6%、82.5%、77.2%、87.7%、86.0%、78.1%、64.9%、52.6%;超声造影诊断的符合率、灵敏度、特异度、阳性和阴性预测值分别为98.1%、88.9%、100%、100%和97.7%。超声造影与胃镜比较差异无统计学意义(P>0.05)。结论:超声造影是一种无创、安全、依从性较高的检查方法,可作为胃十二指肠病变的筛查手段之一。Objective： To investigate the value of oral contrast-enhanced ultrasonography（OCUS） in screening of stomach and duodeum diseases. Methods： OCUS screening was conducted in 228 residents in our hospital. The quality and diagnostic accuracy were compared with gastroscopic results. Results： The image quality was good, almost at level Ⅲ. The rates of level Ⅲ of lower esophagus, cardia, gastric fundus, gastric body, gastric antrum, duodenal bulb, duodenal descending and duodenal horizontal part of duodenum were 77.6%, 82.5%, 77.2%, 87.7%, 86.0%, 78.1%, 64.9% and 52.6%, respectively. The accuracy, sensitivity, specificity, positive and negative predictive values were 98.1%, 88.9%, 100%, 100% and 97.7%, respectively. There was no significant difference between OCUS and gastroscope（P〉0.05）. Conclusion： OCUS is a noninvasive and safe method with high medical compliance. It can be used in the screening of stomach and duodeum diseases.
