【摘要】：目的探讨新生儿缺氧缺血性脑病(HIE)预后应用MRI诊断的意义。方法选取52足月新生儿HIE患儿作为研究对象,对所有患儿进行MRI扫描检查,分析HIE患儿的MRI征象及分度情况,对比各分度HIE患儿的MRI征象差异性,判断MRI对HIE预后的评估价值。结果 HIE的MRI征象:脑白质区域呈斑片状T_1WI高信号有39例,主要以皮层下、皮层深部、侧脑室枕角为主;沿脑回行走的点状及迂曲条带样T_1WI高信号15例;两侧额叶深部白质相当于侧脑室前角外侧可见点状T_1WI稍高信号有25例;沿两侧侧脑室壁边缘条带样高信号有19例;基底节及丘脑斑片状T_1WI高信号有4例,内囊后肢其正常高信号消失1例;蛛网膜下腔出血14例;侧脑室内出血2例;脑白质T_1WI弥漫性低信号,灰白质界限不清1例。52例HIE患儿的MRI分度中,轻度19例、占36.54%;中度28例,占53.85%;重度5例,占9.61%;轻度、中度与重度HIE患儿间的MRI征象(基底节区高信号、内囊后肢高信号消失、侧脑室内出血、脑白质T_1WI弥漫性低信号,灰白质界限不清)具有显著性差异(P0.05)。结论不同分度的HIE具有特异性的MRI征象,可反映患儿的脑损伤情况,评估预后,对HIE预后的诊断效果确切。
[Abstract]:Objective to investigate the significance of MRI in the prognosis of neonates with hypoxic ischemic encephalopathy (HIE).Results the MRI features of HIE were as follows: there were 39 cases with high signal intensity of T_1WI in the white matter region, which were mainly subcortical, deep cortex and lateral ventricular occipital angle, and 15 cases had high signal intensity in punctate and zigzag stripe along the cerebral gyrus.There was significant difference (P 0.05).Conclusion HIE with different grades has specific MRI signs, which can reflect the brain injury in children, evaluate the prognosis, and make a definite diagnosis of the prognosis of HIE.
