目的介绍一种在不使用镇静或麻醉的情况下对婴儿进行核磁共振尿路造影（MRU）的技术。方法18例婴儿在没有镇静药物的情况下，采用“喂裹”技术（FW-MRU）进行核磁共振检查。获得动态对比度增强图像。采用动态径向VIBE和压缩感知图像重构对运动伪影进行校正。结果18例患者中17例成功行FW-MRU。进料和包裹的磁共振尿路图提供了高质量的解剖和肾功能数据。结论采用fwmru的初步经验表明，它是一种很有前途的无麻醉方式，用于获得婴儿尿路的解剖和功能成像。
ObjectiveTo describe a technique for performing magnetic resonance urogram (MRU) in infants without sedation or anesthesia.MethodsEighteen infants underwent MRU in the absence of sedating medications using a 'feed and wrap' technique (FW-MRU). Dynamic contrast enhanced images were obtained. Dynamic radial VIBE and compressed sensing image reconstruction were used to correct for motion artifact.ResultsSeventeen of the 18 patients had successful FW-MRU. Feed and wrap'magnetic resonance urogram provided high-quality anatomic and functional renal data.ConclusionInitial experience with FW-MRU demonstrates it to be a promising anesthesia-free modality for obtaining anatomic and functional imaging of the urinary tract in infants.
