Focal cortical dysplasia (FCD) is thought to be a major cause of cryptogenic localization-related epilepsy, in which conventional MRI is unable to detect a lesion. Scanning at higher field strenghts is likely to increase sensitivity to small lesions, improving the chances of a better surgical outcome. In this pilot study we scanned 10 patients who were diagnosed at 3 Tesla with FCD type II with a 7 Tesla MRI scanner. Features of FCD at 7T were described and compared to the findings at 3T.
