Incorporating the effect of white matter microstructure in the estimation of magnetic susceptibility in ex-vivo mouse brain
Anders Dyhr Sandgaard, Valerij G. Kiselev, Rafael Neto Henriques +2
Accurate estimation of microscopic magnetic field variations induced in biological tissue can be valuable for mapping tissue composition in health and disease. Here, we present an…
To mask or not to mask? Investigating the impact of accounting for spatial frequency distributions and susceptibility sources on QSM quality
Anders Dyhr Sandgaard, Noam Shemesh, Sune Nørhøj Jespersen +1
Estimating magnetic susceptibility using MRI depends on inverting a forward relationship between the susceptibility and measured Larmor frequency. However, an often-overlooked cons…
Larmor frequency shift from magnetized cylinders with arbitrary orientation distribution
Anders Dyhr Sandgaard, Noam Shemesh, Valerij G. Kiselev +1
We present a theoretical framework for the NMR and MRI measured Larmor frequency in media with magnetized microstructure using the mesoscopic Lorentz sphere and the principle of co…
What Does FEXI Measure?
Mohammad Khateri, Marco Reisert, Alejandra Sierra +2
Filter-exchange imaging (FEXI) has already been utilized in several biomedical studies for evaluating the permeability of cell membranes. The method relies on suppressing the extra…
Microstructure with Diffusion MRI: What Scale We Are Sensitive to?
Valerij G. Kiselev
Diffusion-weighted MRI is the forerunner of the rapidly developed microstructural MRI aimed at in vivo evaluation of the cellular tissue architecture. This brief review focuses on…
Observation of magnetic structural universality using transverse NMR relaxation
Alexander Ruh, Philipp Emerich, Harald Scherer +2
Transverse NMR relaxation from spins diffusing through a random magnetic medium is sensitive to its structure on a mesoscopic scale. In particular, this results in the time-depende…
