Diffusion MRI (dMRI) has proven to be a useful imaging approach for both clinical diagnosis
and research investigating the microstructures of nervous tissues, and it has helped us to …

Mapping tissue microstructure with MRI holds great promise as a noninvasive window into
tissue organization at the cellular level. Having originated within the realm of diffusion NMR …

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 work introduces a compartment-based model for apparent cell body (namely soma) and
neurite density imaging (SANDI) using non-invasive diffusion-weighted MRI (DW-MRI). The …

The ultimate promise of diffusion MRI (dMRI) models is specificity to neuronal microstructure,
which may lead to distinct clinical biomarkers using noninvasive imaging. While multi …

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 …

Biophysical models of diffusion in white matter have been center-stage over the past two
decades and are essentially based on what is now commonly referred to as the “Standard …

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 …
