Abstract:

As the non-human primate (NHP) brain is gyroencephalic, structurally and functionally similar to the human brain, NHP stroke models provide an ideal platform for investigating the mechanism of ischemic brain injury and developing therapeutical treatment. In this paper, various NHP ischemic stroke models studied recently are summarized. The imaging protocols available for quantitative MRI measurements of NHP stroke models are introduced.  In addition, data acquisition and physiological motion correction of high-resolution diffusion tensor imaging and continuous arterial-spin-labeling(CASL) based perfusion imaging for NHP are illustrated and discussed. The article provides an overview of NHP stroke models and approach for implementing quantitative multi-parameter MRI evaluation to characterize stroke injury for therapy and drug discovery.

Key words: non-human primate, ischemic stroke model, high-resolution MRI, diffusion-perfusion mismatch, physiological motion correction
