The dependence of the diffusion MRI signal on the diffusion time carries signatures of
restricted diffusion and exchange. Here we seek to highlight these signatures in the human …

Monitoring time dependence with diffusion MRI yields observables sensitive to compartment
sizes (restricted diffusion) and membrane permeability (water exchange). However …

The characteristic signal time-dependence in the brain gray matter indicates a significant
exchange effect, modeled by an extension of the Kärger exchange model. Here we perform …

Purpose To demonstrate that oscillating gradient spin-echo sequences can be combined
with diffusion-weighted magnetic resonance spectroscopy even on clinical MR systems to …

Diffusion‐weighted imaging, a contrast unique to MRI, is used for assessment of tissue
microstructure in vivo. However, this exquisite sensitivity to finer scales far above imaging …

Recent advances in diffusion weighted MRI have reignited interest in spherical (or isotropic)
diffusion encoding. For such encoding to reach high efficiency (minimal echo time), the …

Purpose Oscillating gradient spin‐echo (OGSE) diffusion MRI provides information about the
microstructure of biological tissues by means of the frequency dependence of the apparent …

Scanners with ultra-strong gradients promise unprecedented opportunities for diffusion
imaging. However, their effective use requires correction of gradient-nonlinearity effects …

Diffusion-weighted (DW) MRI is a powerful modality for studying microstructure in normal
and pathological tissues. The accuracy derived from DW MRI depends on the acquisition of …

Strong gradient systems can improve the signal-to-noise ratio of diffusion MRI
measurements and enable a wider range of acquisition parameters that are beneficial for …
