INTRODUCTION: The Wada test has long been a well-established method for evaluating hemispheric dominance and functional localization; however, it has not been established as a visualizable functional imaging modality. Recently, the super-selective Wada test (ssWada) has emerged as a technique enabling more localized functional evaluation. By selectively catheterizing distal cerebral arterial branches, ssWada enables territory-based functional evaluation with higher spatial resolution than...
