Exploration of magnetic resonance urography technique / 医疗卫生装备

ABSTRACT

Objective To explore the clinical application and significance of Magnetic Resonance Urography.Methods T1WI and T2WI images in transverse section and T1WI 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.
