摘　　要：近年,先进的磁共振(MR)技术和3特斯拉磁体(3T)已越来越多地被应用于新生儿,拓宽了围产期缺氧缺血性脑病(HIE)的知识。本文介绍了足月儿缺氧缺血性脑病在3T磁共振的表现,其中包括常规和先进的成像技术,如扩散加权成像(DWI),扩散张量成像(DTI)和磁共振波谱(MRS);重点强调了每种技术发现病灶的时间过程,以及与神经系统预后的关联。During the recent years, advanced magnetic resonance （MR） techniques and 3 Tesla magnets （3T） have increasingly been applied to neonates, and used to expand our knowledge of perinatal hypoxic-ischemic encephalopathy （HIE）. In this review, we present the MR findings at 3T in the full-term neonates with HIE by using conventional imaging and advanced MR techniques, such as diffusion-weighted imaging （DWI）, diffusion tensor imaging （DTI） and MR spectroscopy （MRS）. The time course of lesions seen with each technique is emphasized, and correlated with the neurological outcome.
