摘要
目的:探讨磁共振泌尿系成像(MRU)技术的临床适应证及临床意义。方法:行常规磁共振成像T1 WI及T2 WI轴位及T1 WI冠状位。然后用快速自旋回波重T2 WI加权序列扫描,图像经最大密度投影法重建。结果:20例中18例MRU影像均能满足诊断要求,2例患者检查前准备不充分,检查失败。结论:MRU特别适合尿路狭窄、梗阻及年龄大、体质差、碘过敏等不适宜静脉肾盂造影或静脉肾盂造影不显影的患者。
Objective To explore the clinical application and significance of Magnetic Resonance Urography. Methods T1WI and T2WI images in transverse section and TIWI images in coronary section were obtained. Then fast spiral echo sequence was used to get weighted T2WI images and the images were reconstructed with MIP （maximum intensity projection）. Results Among the 20 cases, 18 MRU images met the diagnostic need, and 2 cases failed because of poor preparation. Conclusion MRU is suitable for the patients who are inappropriate to do IVP （intravenous pyelography）, such as urinary tract restricted and obstructed, old people, poor physical condition and iodine allergy, or the patients who did IVP but there were no contrast agent discerned.
