Language lateralization in epilepsy patients: fMRI validated with the Wada procedure

Purpose:  This work examines the efficacy of functional magnetic resonance imaging (fMRI) for language lateralization using a comprehensive three‐task language‐mapping approach. Two localization methods and four different metrics for quantifying activation within hemisphere are compared and validated with Wada testing. Sources of discordance between fMRI and Wada lateralization are discussed with respect to specific patient examples.
