The diffusion of water molecules inside organic tissues is often anisotropic (1). Namely, if
there are aligned structures in the tissue, the apparent diffusion coefficient (ADC) of water …

Quantification of non‐Gaussianity for water diffusion in brain by means of diffusional kurtosis
imaging (DKI) is reviewed. Diffusional non‐Gaussianity is a consequence of tissue structure …

Diffusion-weighted MRI (DW-MRI) has been increasingly used in imaging neuroscience
over the last decade. An early form of this technique, diffusion tensor imaging (DTI) was …

This work describes a new diffusion MR framework for imaging and modeling of
microstructure that we call q-space trajectory imaging (QTI). The QTI framework consists of …

Based on the Fourier transform relation between diffusion magnetic resonance (MR) signals
and the underlying diffusion displacement, a new relation is derived to estimate the spin …

We present a direct extension of probabilistic diffusion tractography to the case of multiple
fibre orientations. Using automatic relevance determination, we are able to perform online …

A magnetic resonance imaging method is presented for quantifying the degree to which
water diffusion in biologic tissues is non‐Gaussian. Since tissue structure is responsible for …

Diffusional kurtosis imaging (DKI) is a clinically feasible extension of diffusion tensor
imaging that probes restricted water diffusion in biological tissues using magnetic resonance …

Diffusion-weighted magnetic resonance (MR) signals reflect information about underlying
tissue microstructure and cytoarchitecture. We propose a quantitative, efficient, and robust …

Since the realization that diffusion MRI can probe the microstructural organization and
orientation of biological tissue in vivo and non‐invasively, a multitude of diffusion imaging …
