核磁共振和核磁共振波谱结合粗大运动评定量表在儿童脑性瘫痪分度诊断的应用

摘要

Objective To investigate the grading diagnostic value of magnetic resonance spectroscopy and magnetic resonance imaging and gross motor rating scale for children with cerebral palsy.Methods Forty cases of healthy children under 1.0 ～ 2.0 years old and 42 cases of cerebral palsy children under 1.1 ～ 2.0 years old were enrolled in the study,and we compared the inspection reports on MRI and MRS statistical analysis.According to the results of MRI for dividing cerebral palsy,and MRS indexing of NAA/Cr,CHO/Cr,LAC/Cr levels were compared;different types of cerebral palsy by GMFM scores were examined.Results Nuclear magnetic resonance(MRI) and MRS could effectively distinguish typical pathological changes in the brain of children with cerebral palsy,the cerebral NAA,Cr,Cho could appear significant formant when the children detected by MRS,could be quantitatively detected with MRS.The levels of NAA/Cr、CHO/Cr、LAC/Cr of different MRS and MRI degree was different,and the difference of moderate CP and severe CP was significant (P ＜ 0.05).Compared with MRS,the accordant rates of the MRI was not ideal,But gross motor rating scale score suggested that there were differences between the cerebral palsy of the MRI and MRS degree (P ＜ 0.05).Conclusion The magnetic resonance imaging and magnetic resonance spectroscopy and gross motor rating scale can effectively improve the dividing diagnosis of cerebral palsy,and this method for different types of cerebral palsy in children has some guiding value.%目的 探讨头部核磁共振、核磁共振波谱以及粗大运动评定量表对儿童脑性瘫痪的分级诊断价值.方法 40例1.0～2.0周岁的健康儿童和42例1.1 ～2.0周岁的脑性瘫痪儿童为研究对象,对比正常儿童与脑性瘫痪患儿的MRI、MRS检测结果;根据核磁共振结果对脑性瘫痪进行分度,并用核磁共振波谱检测不同核磁共振分度的脑性瘫痪患儿脑内的NAA/Cr、CHO/Cr、LAC/Cr水平并分度;考察不同核磁共振和核磁共振波谱分度脑性瘫痪患儿的粗大运动评定量表得分情况.结果 核磁共振和核磁共振波谱均能有效区分脑性瘫痪患儿脑内的典型病变,脑内的NAA、Cr、Cho能被核磁共振波谱定量检测.不同核磁共振分度的患者脑内的NAA/Cr、CHO/Cr、LAC/Cr有所差异,重度患者与中度患者间的差异具有统计学意义(P＜0.05).脑性瘫痪的核磁共振波谱分度与核磁共振分度相符率不理想,但粗大运动评定量表评分表明各不同分度之间有差异(P＜0.05).结论 核磁共振和核磁共振波谱结合粗大运动评定量表可有效完善脑性瘫痪的分度诊断,这对不同类型儿童脑性瘫痪的临床治疗具有一定的指导意义.
