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 …

This article gives an overview of microstructure imaging of the brain with diffusion MRI and
reviews the state of the art. The microstructure‐imaging paradigm aims to estimate and map …

This paper introduces a multi-compartment model for microscopic diffusion anisotropy
imaging. The aim is to estimate microscopic features specific to the intra-and extra-neurite …

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 …

The first phase of the Human Connectome Project pioneered advances in MRI technology
for map** the macroscopic structural connections of the living human brain through the …

Axon caliber plays a crucial role in determining conduction velocity and, consequently, in the
timing and synchronization of neural activation. Noninvasive measurement of axon radii …

Diffusion MRI is arguably the method of choice for characterizing white matter microstructure
in vivo. Over the typical duration of diffusion encoding, the displacement of water molecules …

The biophysical modeling efforts in diffusion MRI have grown considerably over the past 25
years. In this review, we dwell on the various challenges along the journey of bringing a …

The macro-and microstructural architecture of human brain white matter undergoes
substantial alterations throughout development and ageing. Most of our understanding of …

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 …
