[Abstract] Objective To analyze and explore the clinical application value of CT and MR in the diagnosis of cerebral palsy in children. Methods Convenient selection of eighty children with cerebral palsy admitted to the hospital from June 2016 to December 2018 were enrolled as the subjects of this study. The clinical data were retrospectively analyzed. The children in this study were selected according to their medical records. The number was randomly divided into a control group and an observation group， with 40 cases in each group. The children in the control group were examined by CT examination. The children in the observation group were examined by MR examination. The diagnostic accuracy of the two groups was analyzed and compared. Results In the control group， 3 cases of cerebral ischemia， 2 cases of abnormal white matter， 4 cases of meningitis， 4 cases of brain dysplasia， 2 cases of encephalomalacia and 5 cases of hydrocephalus were detected， with a positive diagnosis rate of 50.0%. In the observation group， there were 8 cases of cerebral ischemia， 4 cases of abnormal white matter， 7 cases of meningitis， 7 cases of brain dysplasia， 4 cases of cerebral softening and 8 cases of hydrocephalus， which reached a positive diagnosis rate of 95.0%. The positive rate in the observation group was significantly higher than that in the control group， and the difference between the two groups was statistically significant（χ2=17.855， P<0.05） . The pathogenic causes of the two groups of children were birth injury， ischemia and hypoxia， and brain congenital dysplasia. Among the 58 positive cases， a total of 11 cases were caused by birth injury. The CT and MR images showed the imaging characteristics of meningitis （4 cases） and encephalitis （7 cases）. A total of 33 children were diagnosed with hypoxia and ischemia， and the CT and MR images showed hydrocephalus （11 cases）， atrophy of gray matter （1 case）， degeneration of white matter （3 cases）， cerebral ischemia （11 cases）， cerebral softening （5 cases） and bilateral subdural effusion （2 cases）. Causes of congenital dysplasia with a total of 14 cases in CT and MR imaging of brain gray matter translocation （2 cases）， split brain malformation （1 case）， no brain （2 cases）， giant brain malformation （2 cases）， corpus callosum dysplasia （3 cases） and brain malformation （1 case）， encephalomalacia foci （1 case） and brain imaging features of multiple calcified plaque （2 cases）. Conclusion Compared with CT， MR has a higher positive diagnosis rate in the clinical diagnosis of cerebral palsy in children， and its application value is higher.
