外科技术发展和免疫抑制剂的应用使肾移植术后一年生存率达到90%以上,但术后多种原因仍可导致移植肾功能不全,及早发现病因并合理治疗可以避免肾功能的丧失,延长移植肾的存活时间。磁共振成像(MRI)具有多方位及多参数成像、无创伤性、无放射性及优越的软组织对比等特点,结合功 The development of surgical techniques and the application of immunosuppressive agents make the one-year survival rate more than 90% after renal transplantation, but still can lead to graft insufficiency after a variety of reasons. Early detection of etiology and rational treatment can avoid the loss of renal function, Extend the survival time of kidney transplant. Magnetic resonance imaging (MRI) with multi-directional and multi-parameter imaging, non-invasive, non-radioactive and superior soft tissue contrast characteristics, combined with work
