新生儿缺氧缺血性脑病后遗症的CT与MRI评价

In CT&MRI Analysis Sequel of Hypoxic Ischemic Encephalopathy of Neonatal

目的 :研究新生儿缺氧缺血性脑病后遣症的脑CT与MRI形态学改变。材料与方法 :对 12 8例HIE患儿进行 2次以上头部CT或MR复查 ,首次在新生儿末期 ,第 2次在 1月～ 8岁。男 82例 ,女 4 6例。年龄 (末次 )为 3月～ 8岁。并对其结果分析。结果 :12 8例中 ,2次复查后 ,CT异常 77例 (6 0 1% ) ;MRI异常 2 8例 (2 1 8% )。其影像学表现分为 6类 :脑萎缩(6 3 2 % ) ;脑积水 (16 4 % ) ;脑梗塞 (40 6 1% ) ;脑软化 (49 2 % ) ;脑囊性改变 (7 6 % ) ;脱髓鞘改变 2 1例 (MRI共检查 2 8例 )。结论 :CT与MRI可反映HIE后遗脑的远期病理形态学改变 ,为HIE早期干预和评估预后提供了客观依据。

Purpose:To study the CT&MRI morphological changes in sequel of HIE.Materials and Methods:Every child of this series has 2 cranial CT&MRI scan.1st scan at end of the newborn stage.2nd scan at months～8 years old.lncluding 82 of male,46 of female and ranging (in the last time) from 3 months～8 years old,and the results were analysed.Results:In 128 cases,77 cases of CT (60 1%) were abnormal,28 cases (21 8%) of MRI were abnormal.include 6 morphological changes:cerebral atrophy (63 2%);hydrocephalus (16 4%);cerebral infarction (40 61%);brain malacia (49 2%);cystic change of degeneration of brain tissue (7 6%);Myelinoclastic changes (21/28).Conclusion:CT&MRI findilgs reflected the patholgical changes of the sequel of HIE,and provided objective basis for dignosis and assessment of prognosis.MRI was much superior than CT
