摘要
目的分析新生儿缺氧缺血性脑病(neonatal hypoxic-ischemic encephalopathy,HIE)的CT、MRI征象,探讨低场MRI和多层螺旋CT对HIE的早期诊断价值。方法收集2009年12月至2011年8月,临床证实并行颅脑CT或/和MRI检查为HIE的患者26例,男性20例,女性6例;年龄30 min至17 d,平均3.12 d(≤1 d者3例、1～5 d者21例),回顾性分析CT检查17例和MRI检查13例(4例患儿同时进行了CT、MRI检查)资料。结果 10例早产儿的脑部损伤以脑室旁白质水肿、分水岭性脑梗死、脑实质或/和脑室内出血为主,16例足月儿脑部损伤以大脑皮层下旁矢状区白质水肿、分水岭区脑梗死、颅内脑外出血为主;17例CT诊断有14例与临床诊断相符合,符合率82.35%,13例MRI诊断有12例与临床诊断相符合,符合率92.31%。结论多层螺旋CT及低场MRI检查对HIE致脑部损伤包括脑水肿、脑梗死、颅内出血等均有较好的显示能力,临床可根据患儿病情和病程的不同选择CT及MRI检查,达到对HIE早期诊断的目的。
Objective To analyze CT and MRI signs of neonatal hypoxic ischemic encephalopatly（HIE） and probe into the value of low-field MRI and multislice spiral CT（MSCT） in early diagnosis of HIE. Methods The CT and MRI traits of 26 patients,including 10 prematures and 16 term infants with HIE,were analyzed retrospectively. Results Edema of white matter,watershed region cerebral infarction and cerebral hemorrhage and/or intraventricular hemorrhage were found in 10 prematures.Subcortical edema,watershed region cerebral infarction and intractanial hemorrhage were found in 16 term infants.Out of the 17 CT cases,14 cases featured the diagnosis results consistent with their clinical diagnosis,indicating a coincidence rate of 82.35%.For the 13 MRI cases,11 cases had the diagnosis results identical to their clinical diagnosis,showing a coincidence rate of 92.31%. Conclusions Both MSCT and MRI are sensitive to cerebral edema,infarction and hemorrhage,and CT and MRI should be selected in terms of pathogenetic condition and course of disease to achieve early diagnosis.
