目的应用结构磁共振成像评估发育性语言障碍(DLD)的早产儿的脑皮层发育的异常变化。方法选取2021年1月至2023年3月本院收治的早产儿39例,将其分为DLD组(20例)和语言发育正常组(19例)。采用3.0 T MRI检查设备在矫正胎龄40~42周行全脑3D-T...目的应用结构磁共振成像评估发育性语言障碍(DLD)的早产儿的脑皮层发育的异常变化。方法选取2021年1月至2023年3月本院收治的早产儿39例,将其分为DLD组(20例)和语言发育正常组(19例)。采用3.0 T MRI检查设备在矫正胎龄40~42周行全脑3D-T_(1)WI MRI检查。应用联影的分割模型及基于脑表面形态学的Infant Freesurfer图像分析软件进行图像处理和皮质表面重建。计算68个脑区的皮质厚度(CT)和皮质表面积(SA),应用SPSS 25.0统计软件对数据进行录入与分析。结果(1)两侧大脑半球CT值比较显示,DLD组显著不对称的脑区是前扣带回峡部、峡状回、下颞叶、外侧枕叶、外侧眶额叶、舌回、副海马、边缘中央回、后中央回、后扣带回、前楔状回、前扣带前回、缘上回(P<0.05);正常组显著不对称的脑区是前扣带回峡部、内嗅、下顶叶、下颞叶、扣带回峡部、外侧枕叶、外侧眶额叶、舌回、副海马、边缘中央回、额下回盖部、前额叶回、后中央回、后扣带回、前扣带前回、缘上回、颞极(P<0.05)。(2)两侧大脑半球SA值比较显示,DLD组显著不对称的脑区为前扣带回峡部、中央额回尾部、下顶叶、扣带回峡部、外侧眶额叶、舌回、内侧眶额叶、中颞叶、副海马、边缘中央回、额下回盖部、额下回眶升支、额下回三角部、后扣带回、顶叶上回、额极、颞横回、岛叶(P<0.05);正常组显著不对称的脑区为前扣带回峡部、中央额回尾部、楔状回、下顶叶、扣带回峡部、外侧眶额叶、内侧眶额叶、中颞叶、副海马、边缘中央回、额下回盖部、额下回眶升支、额下回三角部、后中央回、后扣带回、前楔状回、前扣带前回、颞上回、额极、颞横回、岛叶(P<0.05)。结论DLD早产儿的CT与SA的大脑半球不对称区域较正常组显示较少,表现出较少的左侧偏发育。这表明左侧偏发育减少对DLD早产儿的语言发育具有一定的预测价值,因此应重点关注左侧偏发育减少的早产儿,并及时进行早期干预,以提高其生存质量。展开更多
