摘　　要：目的:探讨磁共振尿路成像(magnetic resonance urography,MRU)检查技术和方法在儿童尿路疾病中的应用价值。方法:回顾性分析16例1～13岁患有尿路疾病儿童的MRU资料,采用常规T2快速恢复快速自旋回波(fastre-covery fast spin echo,FRFSE)和3DMRU序列进行检查。所有图像在AW4.2工作站经最大密度投影(maximumin-tensity projection,MIP)重建出3DMRU图像。结果:16例患者中,MRU诊断先天性发育异常12例,泌尿系统疾病3例,正常1例。16例中10例经手术治疗,6例经临床治疗,均与MRU诊断符合。MRU检查前接受B超检查者16例,CT检查者6例,静脉肾盂造影者9例。各项检查与MRU诊断符合率分别为:B超93.7%(15/16),CT66.7%(4/6),IVP66.7%(6/9)。结论:MRU技术是一种操作简便、诊断可靠的尿路检查手段,在儿童尿路疾病诊断中具有重要价值。Objective To discuss the inspect technique and methods of magnetic resonance urography（MRU）in pediatric urinary system. Mothods 16 cases with urinary system diseases were analyzed retrospectively, including axial routine FRFSE T2WI with fat saturation and three-dimensional MRU. The three-dimensional（3D） imaging data were sent to AW4.2 workstation, then edited and reconstructed with maximum intensity projection（MIP） and rebuilt. Results 12 cases in 16 cases were congenital abnormality by MRU diagnosis, 3 cases were Urinary system diseases and 1 case was normal. 10 cases in 16 cases were performed with surgical intervention, 6 cases with medical treatment, which clinical diagnosis were consistent with MRU. 16 cases were accepted examination with B-ultrasonic, 6 cases CT and 9 cases IVP. Diagnose accordance rates with MRU were B-ultrasonic 93.7%（15/16）, CT 66.7%（4/6）, IVP 66.7%（6/9）.Conclusion MRU is a safe, convincible and convenient technique, which can provide high quality imaging, so it will be a kind of non-injury imaging method in diagnosing the diseases of pediatric urinary system diseases.
