Assessing brain structure and function with diffusion-weighted MRI: Application to stroke

Human brain consists of grey and white matter. Grey matter largely forms the
outer layer of the brain, and is responsible for decision making and functioning
of the human body. Complementary, the white matter (WM) contains the
communication pathways between the grey matter areas. Diffusion-weighted
magnetic resonance imaging (dMRI) is an imaging modality allowing to model
the brain’s white matter structures by making the MRI acquisition sensitive to
diffusion processes. When brain structure is altered due to pathology, it can be
assessed and quantified by analysing dMRI data...
