Predicting Mesoscopic Larmor Frequency Shifts in Ex Vivo Porcine Optic Nerve
Anders Dyhr Sandgaard, André Pampel, Roland Müller +7
Larmor frequency shifts in white matter (WM) vary with fiber orientation due to anisotropic microstructure. Since clinical voxels are significantly larger than these microscopic fr…

Axonal microstructure and compartmentalization impact the orientation and time dependence of mesoscopic transverse relaxation
Anders Dyhr Sandgaard, Rafael Neto Henriques, Noam Shemesh +1
In biological tissue, MR transverse relaxation stems from mechanisms spanning multiple scales, from molecular dipole-dipole interactions to mesoscopic field variations driven by ti…

Predicting Mesoscopic Larmor Frequency Shifts in White Matter with Diffusion MRI -- A Monte-Carlo Study in axonal phantoms
Anders Dyhr Sandgaard, Sune Nørhøj Jespersen
This study aims to validate if MRI can measure anisotropic mesoscopic Larmor frequency shifts from white matter axonal microstructure relative to the B0 direction and if dMRI can e…
