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 …

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 …

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 …

We develop a general analytical and numerical framework for estimating intra-and extra-
neurite water fractions and diffusion coefficients, as well as neurite orientational dispersion …

The key component of a microstructural diffusion MRI 'super-scanner'is a dedicated high-
strength gradient system that enables stronger diffusion weightings per unit time compared …

Abstract Development of therapies for neurological disorders depends on our ability to non-
invasively diagnose and monitor the progression of underlying pathologies at the cellular …

Characterizing neural tissue microstructure is a critical goal for future neuroimaging.
Diffusion MRI (dMRI) provides contrasts that reflect diffusing spins' interactions with myriad …

Purpose To optimize diffusion‐relaxation MRI with tensor‐valued diffusion encoding for
precise estimation of compartment‐specific fractions, diffusivities, and T2 values within a two …
