MRI of acute stroke

MRI is the only imaging technique that can detect stroke injury as early as few minutes after insult. Multi-parameter MRI is increasingly used in the diagnosis of stroke. We have developed multiple MRI techniques including quantitative structural, perfusion, diffusion and functional MRI to image stroke injury with/without treatment.
