The MR findings in patients with spastic diplegia were investigated and the role of MR imaging in assessing the extent of brain injury was evaluated.
39 male and 24 female patients (preterm/term 43/20) were imaged using a 0.5 T MR system.
The MR findings in term patients were quite different from those in preterm patients; 55% of the term patients showed normal and minimal changes on MR, whereas 90.7% of the 43 preterm children had periventricular leucomalacia. The deep cerebral white matter was the most frequently involved site. Objective measurements revealed significant reductions of the entire sagittal area of corpus callosum in diplegic patients in comparison with normal controls. The motor palsy severity correlated well with the extent of corpus callosum involvement.
The corpus callosum appears to be a sensitive marker site for the assessment of the extent of white matter injury.
研究痉挛性双侧瘫患者的磁共振成像（MR）表现，并评估MR成像在评估脑损伤程度中的作用。
使用0.5T MR系统对39例男性和24例女性患者（早产/足月43/20）进行成像。
足月患者的MR表现与早产患者有很大不同；55%的足月患者MR显示正常及轻微改变，而43例早产儿童中有90.7%发生脑室周围白质软化。大脑深部白质是最常受累部位。客观测量显示，与正常对照组相比，双侧瘫患者胼胝体矢状面总面积显著减小。运动麻痹严重程度与胼胝体受累程度密切相关。
胼胝体似乎是评估白质损伤程度的一个敏感标志部位。
