摘　　要：目的探讨磁共振尿路水成像(MRU)联合使用利尿剂的临床诊断价值。方法对20例泌尿系统疾病患者采用快速自旋回波单次激发弛豫增强快速采集(RARE)脂肪抑制序列作冠、矢状多角度采集,先后行常规MRU和静脉注射速尿后MRU扫描,比较二者成像效果。结果20例尿路疾病患者常规MRU未能满意观察尿路情况,经静脉注射速尿后均有不同程度改善而清晰显示尿路走行、管腔狭窄、梗阻病变位置等情况。结论静脉注射利尿剂后MRU较常规MRU更能清晰显示尿路疾病情况。Objective To evaluate the clinical application of magnetic resonance urography （MRU） technique with furosemide injection in urinary tract. Methods 20 patients with urinary tract diseases were simultaneously examined with turbo spin echo, rapid acquisition with relaxation enhancement and fat-suppression pulse sequence pre- and post-injection of furosemide. MRU images from the two different imaging methods were compared and analyzed. Result The images from MRU with administration of furosemide were more clear than those from conventional MRU in showing urinary pathway, site and extent of urinary tract diseases. Conclusion MRU with administration of furosemide injection can be better to demonstrate urinary tract diseases than conventional MRU.
