目的脑性瘫痪的诊断主要靠临床表现,而影像学检查(头颅CT及MRI)对脑瘫的诊断及脑病变的判定起重要作用。痉挛型双瘫以脑室周围白质软化症(PVL)为主,不随意运动型表现为基底病变或PVL,失调型表现为先天性小脑发育不良,偏瘫型主要突出在对侧单侧脑损伤。利用影像学检查(头颅CT及MRI)有助于脑瘫的诊断及脑病变的判定,为脑瘫儿童的治疗或改善预后提供可靠依据。 Purpose The diagnosis of cerebral palsy mainly depends on clinical manifestations, and imaging studies (cranial CT and MRI) play an important role in the diagnosis of cerebral palsy and the determination of brain lesions. Spastic diplegia periventricular leukomalacia (PVL) -based, involuntary exercise manifested as basal lesions or PVL, dysfunction manifested as congenital cerebellar dysplasia, hemiplegia mainly in the contralateral unilateral brain injury. The use of imaging studies (cranial CT and MRI) contribute to the diagnosis of cerebral palsy and the determination of brain lesions, provide a reliable basis for the treatment of children with cerebral palsy or improve prognosis.
