Magnetic resonance assessment of effective confinement anisotropy with orientationally-averaged single and double diffusion encoding
Cem Yolcu, Magnus Herberthson, Carl-Fredrik Westin +1
Porous or biological materials comprise a multitude of micro-domains containing water. Diffusion-weighted magnetic resonance measurements are sensitive to the anisotropy of the the…
On the reconstruction accuracy of multi-coil MRI with orthogonal projections
Anna Breger, Gabriel Ramos Llorden, Gonzalo Vegas Sanchez - Ferrero +3
MRI signal acquisition with multiple coils in a phased array is nowadays commonplace. The use of multiple receiver coils increases the signal-to-noise ratio (SNR) and enables accel…
Dynamics of position-phase probability density in magnetic resonance
Cem Yolcu, Magnus Herberthson, Carl-Fredrik Westin +1
We consider the behaviour of precessional angle (phase) carried by molecules of a diffusing specimen under magnetic fields typical of magnetic resonance experiments. An evolution e…
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…
Tensor-valued diffusion MRI in under 3 minutes: An initial survey of microscopic anisotropy and tissue heterogeneity in intracranial tumors
Markus Nilsson, Filip Szczepankiewicz, Jan Brabec +5
Purpose: To evaluate the feasibility of a 3-minute b-tensor encoding protocol for diffusion MRI-based assessment of the microscopic anisotropy and tissue heterogeneity in a wide ra…
