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,…
Time-dependent diffusion in undulating structures: Impact on axon diameter estimation
Jan Brabec, Samo Lasic, Markus Nilsson
Diffusion MRI may enable non-invasive mapping of axonal microstructure. Most approaches infer axon diameters from effects of time-dependent diffusion on the diffusion-weighted MR s…
Maxwell-compensated design of asymmetric gradient waveforms for tensor-valued diffusion encoding
Filip Szczepankiewicz, Carl-Fredrik Westin, Markus Nilsson
Purpose: Asymmetric gradient waveforms are attractive for diffusion encoding due to their superior efficiency, however, the asymmetry may cause a residual gradient moment at the en…
