150例小儿脑性瘫痪的临床、CT与磁共振分析

研究目的 探讨小儿脑瘫患者CT及磁共振(MRI)形态学改变。 研究方法 对150例脑瘫患儿进行CT与MRI检查,并对其结果进行分析。 结果 150例中,CT异常者97例,占64.65%。弥漫性脑萎缩(42例)、脑软化灶(24例)、脑穿通畸形(9例)、局限性脑萎缩(7例)等是儿童脑瘫常见的CT形态学改变。CT检查正常者53例中,30例行MRI检查,异常25例,占83.3％。脑白质髓鞘形成延迟(14例)是主要的MRI形态学异常。 结论 CT和MRI检查对小儿脑瘫的病因学诊断有重要价值,两者结合可提高诊断符合率。

An analysis of Clinic, CT and MRI in 150 child patients with cerebral palsy

Objective To search for the CT and MRI morphological changes in the child patients with cerebral palsy. Method The CT scranning and MRI were carried out in 150 child patients with cerebral palsy, andthe results were analysed. Results In 150 cases, 97 cases (54.6 per cent) have abnormal findings of CT scranning. Diffuse ence-phalatrophy (42 cases), encephalomalacia focus (24 cases) porencephaly (9 cases), and localized ence-phalatrophy (7 cases) ect are the common CT morphological changes in the patients with cerebral palsy.In the 53 patients with normal findings of CT scranning, MRI was carried out for 30 cases and 25 cases(83.3 per cent) were abnormal. The delayed myelinogeny of white matter of brain is the main MRI mor-phalogical abnormality. Conclusion CT scranning and MRI have important value on the etiological diagnosis for child patientswith cerebral palsy. The combination of them can improve the diagnostic accordance rate.
