摘　　要：目的探讨低场强磁共振成像(MRI)评估新生儿缺血缺氧性脑病(HIE)预后的临床价值。方法回顾性分析82例HIE患儿临床资料,根据1年随访预后情况分为良好组(n=48)与不良组(n=34)。比较两组患儿低场MRI下影像学表现及评分差异。结果良好组低场强MRI下广泛脑水肿、颅内出血、脑白质软化及基底节/丘脑信号异常出现率明显低于不良组,影像学评分各项目及总分均明显低于不良组(P<0.05)。结论新生儿HIE低场强MRI早期评估病情与其预后存在密切联系,有较高临床应用价值。Objective To explore the clinical value of low field intensity magnetic resonance imaging (MRI) in the evaluation of prognosis of neonatal hypoxic ischemic encephalopathy (HIE).Methods The clinical data of 82 children patients with HIE were retrospectively analyzed.According to the prognosis at 1 year follow-up,they were divided into good group (n=48) and poor group (n=34).The low field intensity MRI imaging findings and scores were compared between the two groups.Results The incidence rates of extensive cerebral edema,intracranial hemorrhage,white matter softening and basal ganglia/thalamic signal abnormality in good group were significantly lower than those in poor group,and the imaging items scores and total score were significantly lower than those in poor group (P<0.05).Conclusion Early evaluation of neonatal HIE by low field strength MRI is closely related to its prognosis,and it has high clinical application value.
