摘　　要：目的 评价红氧化铁超顺磁性口服磁共振对比剂在胃部MRI诊断中的应用价值。方法 采用扫描前口服红氧化铁对比剂，对36例年龄21～60岁受检者行胃部MR检查，对图像进行影像学分析。结果 36例受检者服用对比剂后，胃充盈达100％。在各序列扫描中，均呈阴性对比，胃部病变及毗邻关系显示清晰。行MRCP时，可有效抑制胃肠道高信号伪影。结论 在胃部MR检查中，口服红氧化铁对比剂易于接受，安全性好，性能稳定，成像浓度范围宽，是一种优良的胃肠阴性对比剂。Objective To evaluate the applied value superparamagnetic Ferric Oxide oral contrast agent in the dignosis of MR for stomach. Methods Ferric Oxide Suspension was administered before MR scanning of stomach in 36 cases, ranged in age form 21 to 60 years old. MR findings were analysed. Results The fullness of stomach was 100% after administration of Ferric Oxide Suspension. Stomach canal appeared as negative contrast in all MR sequences, the relation between lesions in stomach and around tissue were clearly showed. During MRCP,it could restrict the high signal in stomach canal. Conclusion Oral Ferric Oxide Suspension as contrast agent during MR examination of stomach is easily accepted by patients,it is a safe and steady negative contrast agent for gastrointestinal MR examination.
