The magnitude and preferred direction of water molecule motion (ie diffusion) in a tissue
measured by magnetic resonance imaging (MRI) is dependent on the underlying micro …

We introduce a novel approach to the cerebral white matter connectivity mapping from
diffusion tensor MRI. DT-MRI is the unique non-invasive technique capable of probing and …

Magnetic Resonance Imaging (MRI) techniques have been increasingly applied to the study
of molecular displacement (diffusion) in biologic tissue. The magnetic resonance …

Functional brain imaging methods have contributed enormously to our knowledge of the
anatomic location of particular brain functions. However, there remains a significant gap in …

Diffusion MRI (dMRI) is used to characterize the directionality and microstructural properties
of brain white matter (WM) by measuring the diffusivity of water molecules. In clinical practice …

In this chapter, we cover the basic concepts of diffusion from a non-mathematical
perspective. From the random walk of a water molecule to the effect of obstacles on diffusion …

Diffusion tensor MRI probes and quantifies the anisotropic diffusion of water molecules in
biological tissues, making it possible to non-invasively infer the architecture of the …

In the past, the anisotropic diffusion of water molecules in white matter in the brain has been
correlated to the basic symmetry of the myelin fibers: water diffuses more readily along the …

Generalized diffusion tensor imaging uses tensors of arbitrary ranks to model the angular
variations in the diffusivities measured by magnetic resonance imaging (MRI) methods …

The success of diffusion MRI is deeply rooted in the fact that during their micrometric random
displacements water molecules explore tissue microstructure. Hence by labeling …
