【摘要】：目的探討新生兒缺氧缺血性腦病(HIE)預(yù)后應(yīng)用MRI診斷的意義。方法選取52足月新生兒HIE患兒作為研究對象,對所有患兒進行MRI掃描檢查,分析HIE患兒的MRI征象及分度情況,對比各分度HIE患兒的MRI征象差異性,判斷MRI對HIE預(yù)后的評估價值。結(jié)果 HIE的MRI征象:腦白質(zhì)區(qū)域呈斑片狀T_1WI高信號有39例,主要以皮層下、皮層深部、側(cè)腦室枕角為主;沿腦回行走的點狀及迂曲條帶樣T_1WI高信號15例;兩側(cè)額葉深部白質(zhì)相當于側(cè)腦室前角外側(cè)可見點狀T_1WI稍高信號有25例;沿兩側(cè)側(cè)腦室壁邊緣條帶樣高信號有19例;基底節(jié)及丘腦斑片狀T_1WI高信號有4例,內(nèi)囊后肢其正常高信號消失1例;蛛網(wǎng)膜下腔出血14例;側(cè)腦室內(nèi)出血2例;腦白質(zhì)T_1WI彌漫性低信號,灰白質(zhì)界限不清1例。52例HIE患兒的MRI分度中,輕度19例、占36.54%;中度28例,占53.85%;重度5例,占9.61%;輕度、中度與重度HIE患兒間的MRI征象(基底節(jié)區(qū)高信號、內(nèi)囊后肢高信號消失、側(cè)腦室內(nèi)出血、腦白質(zhì)T_1WI彌漫性低信號,灰白質(zhì)界限不清)具有顯著性差異(P0.05)。結(jié)論不同分度的HIE具有特異性的MRI征象,可反映患兒的腦損傷情況,評估預(yù)后,對HIE預(yù)后的診斷效果確切。
[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.
