Tuberous sclerosis complex (TSC) is an autosomal dominant genetic disease. 90% of patients with TSC suffer from epilepsy and 50% of them become medicine intractable epilepsy. Epilepsy surgery is an important treatment. However, some focal epileptogenic lesions, essential for surgery, are not well identified by current routine imaging protocols at 3T. 7T MR imaging is assessed in this study to allow better characterization of lesion details and to detect abnormalities previously unseen on 3T MRI and scalp electroencephalogram (EEG). This is the first report of clinical application of 7T MRI for pediatric patients (older than 8 years) with TSC epilepsy.
