对29例脑瘫患儿行头颅CT、MRI及SPECT检查，并进行分析。本组脑瘫病因主要是宫内及出生时窒息、早产低体重儿、核黄疸三大因素。CT异常率79．3％，弥散性脑萎缩、脑软化灶等为主要的CT改变。MRI异常26例，异常率89％，以弥漫性脑萎缩、脑软化灶、脑白质发育不良等为主要的MRI改变。SPECT异常27例，异常率93％，脑局部血流灌注减少为主要改变。认为CT和MRI及SPECT检查对脑瘫病因学诊断有重要价值。
29 children with cerebral palsy underwent cranial CT, MRI and SPECT examination, and analyzed. The causes of cerebral palsy in this group are mainly intrauterine and postnatal asphyxia, premature low birth weight children, three factors of nuclear jaundice. CT abnormalities 79.3%, diffuse brain atrophy, cerebral softening as the main CT changes. MRI abnormalities in 26 cases, the abnormal rate of 89% to diffuse brain atrophy, cerebral softening, white matter dysplasia as the main MRI changes. 27 cases had abnormal SPECT, the abnormal rate was 93%, and the decrease of local cerebral perfusion was the main change. That CT and MRI and SPECT examination of the etiology of cerebral palsy diagnosis of great value.
