Abstract:
Objective：To investigate the results of brain MRI in children with febrile seizures in order to provide the basis for using brain MRI properly.
Methods：The clinical data of 192 children with febrile seizures hospitalized from June 2013 to June 2014 examined with brain MRI were analyzed retrospectively，and the rate of abnormal brain MRI result was compared between the children with simple febrile seizures and complex febrile seizures.
Results：There were 167 cases of simple febrile seizures and 25 cases of complex febrile seizures in all 192 children with febrile seizures.Abnormal brain MRI results were detected in 25 cases，the rate of abnormal MRI was 10.2% in simple febrile seizures and 32% in complex febrile seizures.There was significant difference in the rate of abnormal brain MRI between children with simple febrile seizures and complex febrile seizures.
Conclusion：The brain MRI doesn't need to be used routinely in children with simple febrile seizures.If there is higher positive rate of brain MRI in children with complex febrile seizures and basic pathological changes are found，the brain MRI should be used routinely.
