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 …

Phantoms, both numerical (software) and physical (hardware), can serve as a gold standard
for the validation of MRI methods probing the brain microstructure. This review aims to …

Measuring the time/frequency dependence of diffusion MRI is a promising approach to
distinguish between the effects of different tissue microenvironments, such as membrane …

For many pathologies, early structural tissue changes occur at the cellular level, on the scale
of micrometers or tens of micrometers. Magnetic resonance imaging (MRI) is a powerful non …

Conventional diffusion imaging uses pulsed gradient spin echo (PGSE) waveforms with
diffusion times of tens of milliseconds (ms) to infer differences of white matter microstructure …

The detection sensitivity of diffusion MRI (dMRI) is dependent on diffusion times. A shorter
diffusion time can increase the sensitivity to smaller length scales. However, the …

Fiber tractography is widely used to non-invasively map white-matter bundles in vivo using
diffusion-weighted magnetic resonance imaging (dMRI). As it is the case for all scientific …

The standard diffusion MRI model with intra-and extra-axonal water pools offers a set of
microstructural parameters describing brain white matter architecture. However, non …

Increasingly, attention is being directed towards time-dependent diffusion magnetic
resonance imaging (TDDMRI), a method that reveals time-related changes in the diffusional …
