title: Basic concepts of functional arteriovenous MR imaging malformations.
abstract: This article reviews the technical features of functional MR imaging. Examples are presented demonstrating how MR imaging may be used to identify primary cortical regions adjacent to AVMs. Preliminary results suggest that cortical functions may undergo translocation when the AVM involves eloquent cortex. This finding underscores the importance of cortical mapping prior to surgical excision.
