Note: EF localization concordance between AI mapping and the clinical hypothesis is reported in the second column
Abbreviations: +, concordant with clinical hypothesis or improved confidence after PET/DTI; ++, PET/DTI improved confidence and indicated that the patient may benefit from an anterior temporal lobectomy; −, discordant with clinical hypothesis or unchanged confidence after PET/DTI
