Purpose : To compare Brain MRI and SPECT findings in children with cerebral palsy
Subject : 60 children with cerebral palsy 1) Spastic diplegia : 44 pts 2) Spastic qudriplegia : 11 pts 3) Spastic hemiplegia : 2 pts 4) Athetoid type : 3 pts

Questions ?
1. Is PVL the etiologic factor in the pathogenesis of spastic type of CP ?
2. Is the damage of the corticospinal tract caused by PVL ?
Park et al. (1997, J Korean Acad Rehabil Med)
SPECT findings Normal Abnormal hypoperfusion
Thalamus Cerebellum Cortex except temporal lobe Basal ganglia Temporal lobe Central sulcus
3. Is the spasticity and motor dysfunction of CP caused by damaged corticospinal tract ?
