3. Background High-resolution brain MRI is currently an integral component in the diagnostic evaluation of children with focal epilepsy. When focal epileptogenic abnormalities are identified, such as cortical dysplasia, the management strategy includes evaluation for potential surgical resection, which may dramatically improve outcome. The current clinical state of the art of 3T MRI has superior sensitivity over conventional 1.5T MRI. However focal cortical dysplasia remains one of the most common pathological diagnoses after pediatric epilepsy surgery, even when not detected by current MRI exams.
