Objective To study the early diagnostic value of CT for children with cerebral palsy.Methods CT manifestations of 124 cases with cerebral palsy were analysed retrospectively. Results 96 cases of the 124 cases showed a recognisable abnormality,the abnormal rate of CT was about 77.42％ ,and the most common abnormality was cerebral atrophy.Spastic type was the most common clinical type(71.77％ ).The less of the age,the higher of the abnormal rate of CT. Conclusion Although CT isn't the main basis of the diagnosis of cerebral palsy,it's helpful for us to find the pathological changes,and to find the eliology and location.It also provided basis for us to judge the prognosis of cerebral palsy.So CT has significant value in the early diagnosis of cerebral palsy.
