In this study series with status epilepticus (SE) pediatric patients, we investigated the utility diffusion weighted magnetic resonance imaging with a high b-value (b = 3000 s/mm2) compared with standard b-value (b = 1000 s/mm2) for acute ictal MRI changes in pediatric patients. High b-value diffusion weighted imaging (DWI) could be beneficial for detecting additional lesions and improving the contrast between lesions and normal tissue. Therefore, high b-value DWI may be a better noninvasive imaging method for exploration of the acute ictal MRI changes in pediatric patients with SE.
