目的：分析小儿脑性瘫痪患者的危险因素与MRI检查结果，探讨不同危险因素所致MRI检查结果有何不同。方法：回顾分析273例脑瘫患儿的临床资料与MRI检查结果，观察不同危险因素所致脑瘫的MRI检查结果。结果：273例脑瘫患儿中，MRI异常表现者222例，异常率81％。其中早产37例，异常率为81%；足月产并窒息27例，异常率为85%；早产并窒息者48例，异常率为81%；发育畸形29例，异常率为86%；低体质量儿16例，异常率为87.5%；早产、足月产合并有高热病史的异常率分别为81%、 67.6%；核黄疸24例，异常率为87.5%。结论：头颅MRI检查对脑瘫的诊断有重要价值，不同危险因素所致脑瘫其MRI表现不同，主要以脑白质及胼胝体发育不良为主。  

Objective: To analyze the correlation of the risk factors of patients with cerebral palsy and MRI examination results, to explore the diagnosis value of MRI for children with cerebral palsy. Methods: We retrospectively analyzed the clinical data of 273 patients with cerebral palsy and MRI examination results, observed the MRI findings of cerebral palsy caused by different risk factors. Results: There were 222 abnormal cases, the abnormal rate was 81%. There were 37 premature cases, the abnormal rate was 81%. There were 27 cases with asphyxia, the abnormal rate was 85%. There were 48 cases of preterm delivery with asphyxia, the abnormal rate was 81%. There were 29 developmental malformation cases, the abnormal rate was 85%. There were 16 cases of low birth weight, the abnormal rate was 87.5%. Abnormal rate of preterm and term delivery were 81%, 67.6% respectively. There were 24 kernicterus cases, the abnormal rate was 87.5%. Conclusion: MRI examination has important value to the diagnosis of cerebral palsy. Cerebral palsy caused by different risk factors has its own MRI manifestations, cerebral white matter dysplasia and agenesis of corpus callosum are the main appearances.
