摘要：目的探讨磁共振弥散加权成像（DWI）对早产儿脑白质损伤的早期评价和诊断价值。方法收集2007年2月至2012年8月因缺氧而收入我院新生儿重症监护室（NICU）疑似早产儿脑白质损伤的早产儿57例，对其进行头颅B超检查，并同步进行DWI检查。结果（1）早产儿脑白质损伤早期DWI脑室周围白质水肿区高信号。磁共振成像（MRI）呈T1WI呈低信号，T2WI呈高信号。（2）DWI诊断早产儿脑白质损伤的特异度为95%。结论（1）DWI显示的双侧脑室周围白质对称性弥漫性高信号是脑白质损伤的最早期表现。（2）DWI能发现早期脑白质损伤病变，早产儿脑白质损伤早期临床表现缺乏特异性，建议常规行头颅MRI检查。

Abstract:ObjectiveTo study the diffusion-weighted magnetic resonance imaging(DWI)in the preterm infants with early cerebral white matter damage diagnosisMethodsWe collected suspected cerebral white matter damage(CWMD)Children with hypoxia who were treated in Affiliated Lai Gang hospital,Tai shan medical college NICU from February 2007 to August 2012the 57 cases who accept ultrosound inspection and simultaneously we used DWI to examine all of the infantsResults(1)Focal injury ,hign signal appeared on DWIConventional MRI showed low signal intensity on T1- weighted imaging and hign signal intensity on T2- weighted imaging(2)The specificity was 95%Conclusion(1)Bilateral,symmetric,diffuse high signal intensity on DWI seemed to be the eayliest evidence of CWMD(2)DWI could detect the lesions in eayly stage of CWMD，there were no specific clinical manifestations of CWMD,so it was suggested MRI should be perfomed as a routine in preterm infants
