Overview
MRI is the imaging modality of choice for Japanese encephalitis. On MRI, Japanese encephalitis is characterized by symmetric or asymmetric bilateral thalamic hypodensities, and subacute or chronic hemorrhagic lesions.[1][2]
MRI
MRI is the imaging modality of choice for Japanese encephalitis. On MRI, Japanese encephalitis is characterized by symmetric or asymmetric bilateral thalamic hypodensities, and subacute or chronic hemorrhagic lesions.[1][2] Findings of Japanese encephalitis on MRI include:[3][4][5]
- Parenchymal edema in affected regions
- DWI: variable restricted diffusion
- T1: low signal
- T2/FLAIR: high signal
- GRE: patchy blooming (if hemorrhage is present)
