Abstract: Objective To analyze the MRI features of viral encephalitis in children.Methods MRI data of 33 children with viral encephalitis diagnosed and treated by clinic were analyzed retrospectively for lesion location,shape,characteristics in multi-sequence and dynamic follow-up.Results The positive rate of MRI detection was 93.93%,including 20 cases involved in the limbic system,3 cases involved in the non-limbic system,and 8 cases involved in both limbic system and non-limbic system simultaneously.22 cases (70.96%)showed low signal in T1WI.25 cases (80.64%)showed high signal in T2WI,with slightly in 15 cases (60%)and obviously in 10 cases (40%).29 cases (93.54%)showed high signal in T2WI-FLAIR,with slightly in 6 cases (20.68%)and obviously in 23 cases (7 9 .3 1 %). The MRI manifestations were not synchronized with the clinical symptoms,the abnormal signal of MRI disappeared later than the clinical symptoms.Conclusion To a certain extent,the MRI findings can provide evidences for diagnosis,therapy,supervision and prognosis of viral encephalitis.
