We review, systematize and discuss models of diffusion in neuronal tissue, by putting them
into an overarching physical context of coarse‐graining over an increasing diffusion length …

Diffusion weighted magnetic resonance imaging (DWI) and related techniques such as
diffusion tensor imaging (DTI) are uniquely sensitive to the microstructure of the brain and …

In this work we investigate the use of sum of squares constraints for various diffusion-
weighted MRI models, with a goal of enforcing strict, global non-negativity of the diffusion …

In vivo diffusion phenomena using magnetic resonance (MR) techniques were first
described by Stejskal and Tanner 1 in 1965. In 1986, Le Bihan and colleagues 2 applied …

Cerebral edema is associated with multiple neurological conditions including stroke,
traumatic brain injury and brain tumors. Two main types of cerebral edema can be …

Diffusion Tensor Imaging (DTI) is one of the most widespread techniques for obtaining
information about the underlying tissue geometry and integrity in brain white matter. Despite …
