MRI plays a vital role in the localization and
characterization of epileptogenic abnormalities. High
field MRI has been useful in characterizing hippocampal
sclerosis, cortical dysplasias, and vascular
malformations associated with epilepsy. We report
results for a study designed to assess the value of 7T
imaging to reveal subtle abnormalities acting as
epileptogenic foci in patients with idiopathic focal
epilepsy who have non-lesional diagnostic MRI scans. We
report all abnormalities detected at 7T, including those
that have had an impact on surgical planning and
treatment course as well as findings that could assist
with better understanding the etiology of the disease.
