摘　　要：目的:了解早产儿脑损伤的发生率及探讨磁共振检查对早产儿脑损伤的诊断价值。方法:对我院住院早产儿130例在生后1周内行头颅磁共振检查。结果:早产儿脑损伤的发生率为63.8%,以出血性病灶较多见(29.2%),其次为出血合并缺血性病灶(24.6%)。弥散加权成像对脑白质损伤较敏感,磁敏感加权成像对出血较敏感。结论:磁共振检查对早产儿脑损伤的诊断提供了准确的影像学依据。Objective：To investigate the incidence and diagnostic value of MRI in premature infants with brain damage.Method： One hundred and thirty cases of premature infants＇ brains were detected by MRI within one week after their birth.Results： The incidence of brain lesion in premature infants was 63.8%,of which hemorrhage was much higher with an incident rate of 29.2%,and hemorrhage and ischemic lesion was the second with an incident rate of 24.6%.DWI was more sensitive to white matter damage,and SWI was sensitive to hemorrhagic focus.Conclusion： MRI provided an accurate imaging for brain damage diagnosis in premature infants.
