MRI对脑瘫患儿的诊断价值及意义

目的探讨MRI在小儿脑瘫诊断中的价值及意义。方法回顾性分析2013年5月至2015年1月于我院治疗并确诊的CP患儿25例,对其MRI影像学分类及临床分型进行总结分析;结果全部25例CP患儿经MRI检查结果正常为6例、异常为19例,总阳性率为76%。依据影像学分类将脑瘫分为,脑白质病变12例(48%)、胼胝体病变5例(20%)、软化灶3例(12%)、脑萎缩2例(8%);脑白纸病变CP患儿中6例为四肢瘫、1例为双瘫、2例为偏瘫、1例为肌张力低下型、2例为混合型;胼胝体病变5例中,3例为四肢瘫、2例为即张力低下型;基底节软化灶3例中,1例为四肢瘫、2例为偏瘫;脑萎缩2例均表现为四肢瘫。痉挛型四肢瘫、双瘫、偏瘫阳性率分别为80%、100%、80%,肌张力减低型阳性检出率为75%,混合型阳性检出率为66.6%;结论 MRI检查可以作为检查脑内病变部位和性质的的首选方法,可以确切提示脑部病变的性质、部位和范围,对小儿CP的病因分析、指导用药和判断预后均具有重要价值,适宜临床推广使用。

The Diagnostic Value of MRI in Children with Cerebral Palsy and Signiifcance

Objective To evaluate the value of MRI in the diagnosis of children with cerebral palsy and significance.Methods Were retrospectively analyzed in May 2013 to January 2013 in our hospital treatment and diagnosis of CP children with 25 cases, MRI imaging to its classification and summarize clinical classification analysis.Results all 25 cases of CP children with normal by MRI examination results for 6 cases, abnormal for 19 cases, total positive rate was 76%. Based on radiographic classification will be divided into cerebral palsy, 12 cases of cerebral white matter lesions (48%), the subcallosal sacral body lesions in 5 cases (20%), softening oven in 3 patients (12%), 2 cases of brain atrophy (8%), 6 patients with brain lesions in children with CP, white paper for quadriplegics, 1 case for double collapsed, 2 cases of hemiplegia, 1 case for low muscle tone, 2 cases of mixed type; Subcallosal sacral body lesions in 5 cases, 3 cases of tetraplegia type, 2 cases as the tension is low; Basal ganglia softening oven in 3 cases, 1 case of quadriparesis, 2 cases of hemiplegia; Brain atrophy in 2 cases were presented with tetraplegia. Spasm, double paralysis, hemiplegia type tetraplegia positive rate were 80%, 100%, 80%, reducing muscle tension type positive detection rate of 75%, mixed type positive detection rate is 66.6%.Conclusion MRI can be used as a check of pathological changes of the brain and the nature of the preferred method, can be exactly indicate the nature of brain lesions, location and scope, analysis on the cause of children with CP, guiding medication and judging the prognosis has important value, suitable for clinical use.
