脑性瘫痪的MRI诊断价值

MRI Assessment of Cerebral Palsy in Children

目的:探讨脑性瘫痪患儿MRI形态学改变及诊断价值。方法:回顾性研究35例脑瘫患儿的头颅资料(1.5T),其中痉挛性脑瘫16例,锥体外系脑瘫7例,肌张力低下脑瘫4例,混合型脑瘫8例。结果:32例患儿(91%)颅脑MRI显示异常。其中脑萎缩11例,脑白质髓鞘发育延迟8例,脑室周围白质软化灶6例,基底节异常信号5例,脑软化灶5例,皮层梗死病灶3例,先天畸形4例。3例患者MRI检未见明确异常。结论:MRI检查对小儿脑瘫的早期诊断和预后判断有重要价值。

Objective To evaluate the effect of magnetic resonance imaging （MRI） on cerebralpal sy （CP） in children. Methods In 35 children with cerebral palsy, the brain scans were studied with 1.5 T magnetic resonance scanner. The typos of palsy were spastic CP（n = 16） ,extrapyramildal CP （n =7） ,hypotonic CP （n =4） ,and mixed CP （n =8）. Results Of all patients,32 （91% ） demonstrated abnormal findings with MRI. MRI showed brain atrophy in 11 cases,delayed myelinization in 8 cases ,periventricular leukomalacia in 6 cases,abnomal signals of the basal ganglia in 5 cases,brain malaria in 5 cases,cortical infarction in 3 cases and congenital deformation in 4 cases, no abnormal finding in 3 cases. Conclusion MRI is a useful tool for the early diagnosis and the prognosis of cerebral palsy in children.
