This study describes the development of a large non-human primate (baboon) stroke model (permanent and transient stroke) and the implementation of multiparametric MRI protocols to characterize the evolution of lesion volume, the perfusion-diffusion mismatch, quantitative CBF and ADC changes, and cerebral vascular reactivity. Improved understanding of the lesion evolution and perfusion-diffusion mismatch in clinically relevant model of stroke might provide important information to better guide clinical diagnosis, test novel interventions and improve treatment time windows.
