RT Journal Article T1 Dipole density of low-frequency and spike magnetic activity: A reliable procedure in presurgical evaluation of temporal lobe epilepsy A1 Fernández Lucas, Alberto Amable A1 de Sola, Rafael G. A1 Amo, Carlos A1 Turrero Nogués, Agustín A1 Zuluaga Arias, María del Pilar A1 Maestu Unturbe, Fernando A1 Campo, Pablo A1 Ortiz, Tomás AB Conventional visual analysis and dipole density analysis of magnetoencephalographic data for both spike and low-frequency magnetic activity were compared for presurgical evaluation in temporal lobe epilepsy (TLE) in a sample of 26 drug-resistant operated TLE patients. A series of logistic regression analyses were performed. Dipole density sensitivity was superior to visual localization analysis. Three separated logistic models were calculated for interictal spikes, low-frequency magnetic activity, and the combination of both measures. A combined interictal spike/low-frequency magnetic activity model predicted correctly the operated temporal lobe in all patients. Clear-cut criteria for the probability model are proposed that are valid for 92.3% of cases in the sample. The quantitative approach proposed by this study is an evidence-based model for presurgical evaluation of temporal lobe epilepsy, which improves previous magnetoencephalographic investigations and establishes working clinical criteria for patient evaluation in TLE.
