Diffusion MRI with double diffusion encoding and variable mixing times disentangles water exchange from intrinsic kurtosis
Arthur Chakwizira, Filip Szczepankiewicz, Markus Nilsson
Double diffusion encoding (DDE) makes diffusion MRI sensitive to a wide range of microstructural features, and the acquired data can be analysed using different approaches. Correla…
Probing restricted diffusion and exchange using free gradient waveforms: validation by numerical simulations
Arthur Chakwizira, Carl-Fredrik Westin, Jan Brabec +4
Monitoring time-dependence with diffusion MRI yields observables sensitive to compartment sizes (restricted diffusion) and membrane permeability (water exchange). However, restrict…
aDWI-BIDS: an extension to the brain imaging data structure for advanced diffusion weighted imaging
James Gholam, Filip Szczepankiewicz, Chantal M. W. Tax +7
Diffusion weighted imaging techniques permit us to infer microstructural detail in biological tissue in vivo and noninvasively. Modern sequences are based on advanced diffusion enc…
Gradient waveform design for tensor-valued encoding in diffusion MRI
Filip Szczepankiewicz, Carl-Fredrik Westin, Markus Nilsson
Diffusion encoding along multiple spatial directions per signal acquisition can be described in terms of a b-tensor. The benefit of tensor-valued diffusion encoding is that it unlo…
Magic DIAMOND: Multi-Fascicle Diffusion Compartment Imaging with Tensor Distribution Modeling and Tensor-Valued Diffusion Encoding
A. Reymbaut, A. Valcourt Caron, G. Gilbert +5
Diffusion tensor imaging provides increased sensitivity to microstructural tissue changes compared to conventional anatomical imaging but also presents limited specificity. To tack…
The Kärger vs bi-exponential model: theoretical insights and experimental validations
Nicolas Moutal, Markus Nilsson, Daniel Topgaard +1
We revise three common models accounting for water exchange in pulsed-gradient spin-echo measurements: a bi-exponential model with time-dependent water fractions, the Kärger model,…
