A comparison of magnetoencephalography, MRI, and V-EEG in patients evaluated for epilepsy surgery.

摘要: Summary: Purpose: To determine the efficacy and relative contribution of several diagnostic methods [ictal interictal scalp intracranial EEG, magnetic resonance imaging (MRI), magnetoencephalography (MEG)] in identifying epileptogenic zone for resection. Methods: This was a prospective study using masked comparison-to-criterion standard. Fifty-eight consecutive patients with refractory partial epilepsy from two university comprehensive programs were studied. Patients who evaluated underwent surgery recruited. The main outcome measure each method to identify resected zone, when referenced surgical outcome. Results: MEG (52%) second only ictal V-EEG predicting entire group had an excellent (seizure free or rare seizure). In subanalysis, temporal lobe surgery, this same relation seen (MEG, 57%, V-EEG, 62%). With extratemporal resection, (81%) (75%) EEG superior (44%) site those outcome. Finally, all good outcome, better than (33%) (45%) VEEG surgery. Conclusions: These results indicate that is very promising raise possibility it may obviate need invasive some cases reduce length evaluation others.
