Unveiling neuronal microstructure in the human brain in vivo with time-dependent radial diffusivity in MRI
Ante Zhu, Jerome J. Maller, H. Douglas Morris +14
Diffusion time-dependence, defined as variations in diffusivity and/or diffusional kurtosis with diffusion time, has emerged as a valuable non-invasive imaging marker for character…
Characterising Water Exchange in Gliomas Using Diffusion MRI with Free Gradient Waveforms
Arthur Chakwizira, Filip Szczepankiewicz, Carl-Fredrik Westin +3
Transmembrane water permeability, which regulates cellular water exchange and is influenced by water channels such as aquaporin-4 (AQP4), has been implicated in glioma progression…
Diffusion MRI with free gradient waveforms on a high-performance gradient system: Probing restriction and exchange in the human brain
Arthur Chakwizira, Ante Zhu, Thomas Foo +3
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 br…
SNR-enhanced diffusion MRI with structure-preserving low-rank denoising in reproducing kernel Hilbert spaces
Gabriel Ramos-Llordén, Gonzalo Vegas-Sánchez-Ferrero, Congyu Liao +3
Purpose: To introduce, develop, and evaluate a novel denoising technique for diffusion MRI that leverages non-linear redundancy in the data to boost the SNR while preserving signal…
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…
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…
