探讨三种对比剂在MRU检查中的应用

The Application of use Three Contrasts in the MR Urography(MRU)

目的探讨三种对比剂在泌尿系水成像(MRurography,MRU)检查前作为胃肠道准备的对比剂的效果性价比。材料和方法采用GESigna1.5T磁共振扫描仪对542例分别服用BaSO4、Gd-DTPA、枸橼酸铁铵三种对比剂做胃肠道准备后进行MRU检查。结果全部病例均能显示MRU的整个图像,服用造影剂后产生胃肠道伪影的病例数明显减少。结论由此可见在做MRU检查前作好胃肠道的准备是很重要的。且钆苯酸葡胺的性价比在三者中最优,采用5‰钆苯酸葡胺作为MRU检查前的胃肠道准备对比剂,是较为理想的。

Objective To evaluate three contrasts use as gastroenteric contrast before MR urography （MRU）. Methods collect MRU of 542 cases oral different contrast prepare the gastroenter Results Very few of MRU images was affected by gastroenteric trace. Conclusion It is important use gastroenteric contast before MRU. The 5%oGd-DTPA is the best gastroenteric contast of the MRU.
