Exploring the predictive value of lesion topology on motor function outcomes in a porcine ischemic stroke model

Abstract Harnessing the maximum diagnostic potential of magnetic resonance imaging (MRI) by including stroke lesion location in relation to specific structures that are associated with particular functions will likely increase the potential to predict functional deficit type, severity, and recovery...
