Abstract:
Objective To study the follow-up value of MRI in the sequela hypoxic-ischemic encephalopathy(HIE).Methods MRI features of HIE in 81 neonates were analyzed retrospectively,every child had two cranial MRI scans,the first scan at the end of the newborn stage,the second scan at 4 months to 4 years.There were 66 full-term neonates and 15 preterm neonates.Results Of 81 cases,79 cases were abnormal on second MRI examination,including myelinogenetic abnormal in 59 cases(72.8%),external hydrocephalus(EH) in 53 cases(65.4%),brain malacia in 26 cases(32.1%),cerebaral atrophy in 25 cases(30.1%),white matter decrease in 24 cases(29.6%) and dysplasia of corpus callosum in 9 cases(11.1%).EH(26/35cases) and myelinogenetic abnormal(16/35 cases) in mild HIE group,brain malacia(12/29 cases) in moderate HIE group,cerebaral atrophy(16/17 cases) and white matter decrease(15 /17 cases)in severe HIE group were often seen.Conclusion MRI findings can reflect the pathological changes of sequela of HIE,and provide objective basis for diagnosis and assessment of prognosis.
