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…
A Unique Analytical Solution of the White Matter Standard Model using Linear and Planar Encodings
Marco Reisert, Valerij G. Kiselev, Bibek Dhital
Diffusion-weighted magnetic resonance imaging in brain white matter probes tissue microstructure and allows for the estimation of compartmental diffusion parameters. Recently, it b…
Intra-axonal Diffusivity in Brain White Matter
Bibek Dhital, Marco Reisert, Elias Kellner +1
Biophysical modeling is the mediator of evaluating the cellular structure of biological tissues using diffusion-weighted MRI. It is however the bottleneck of microstructural MRI. B…
Gibbs-Ringing Artifact Removal Based on Local Subvoxel-shifts
Elias Kellner, Bibek Dhital, Marco Reisert
Gibbs-ringing is a well known artifact which manifests itself as spurious oscillations in the vicinity of sharp image transients, e.g. at tissue boundaries. The origin can be seen…
