 Cerebral vascular disorder is one of the most fatal diseases despite current advances in medical science. The large number of negative clinical trials on neuroprotection in acute stroke is a pointer to the fact that translating better understanding of the pathogenesis and pathophysiology to clearly beneficial treatment strategies remains a daunting task. This project aims at elucidating the plausible biophysical events that affect water and metabolite diffusion in brain tissue after ischemia, by combining the information provided by two advanced methods of magnetic resonance MR diffusion imaging: diffusional kurtosis imaging and diffusion-weighted spectroscopy.
