Abstract:
Objective To investigate the applications of total maturation scores (TMS) in assessment of the hypoxic ischemic encephalopathy (HIE) group and matched group with MRI and to find which patterns of HIE can delay the brain maturation in neonate.Methods MRI were performed on 43 full term neonates (28 HIE newborns and 15 matched controls) who were further divided into three groups,including 37-39 weeks postmenstrualage (PMA) (13 cases),39-41 weeks PMA (16 cases),and 41-44 weeks PMA (14 cases).MRI features and TMS scores were evaluated simulataneously.Results TMS gradually increased with PMA at each stage.While TMS,cortical folding and germinal matrix were all higher in matched group (P＜0.05),myelination and glial cell migration item were lower in HIE group (P＞0.05).Conclusion TMS can reflect brain development in the full term neonates.HIE may delay the brain maturation due to injury of the cortical myelin and neurons.TMS can evaluate the neonatal brain development and injury easily,quantitatively and effectively.
