Abstract:
The high-resolution, phased array, or surface coil techniques offer promise of improvements in diagnosis of cortical abnormalities. Further prospective studies in larger numbers of patients will be needed to determine the exact improvement, which might be expected from experienced image interpreters. Combining high-resolution imaging with MEG would seem to be the best noninvasive way of accurately localizing seizure foci, and any potential anatomic derangements, currently available to us.
