Trusting the Inverse: Reliability-Aware Mapping for Simulation-Based Microstructure Estimation in Diffusion MRI
Juan Luis Villarreal Haro, Ileana Jelescu, Jean-Philippe Thiran +1
Diffusion-weighted MRI can probe tissue microstructure non-invasively, however interpreting microstructural parameter estimates remains challenging due to the intrinsic ambiguity o…
Microstructure estimation from diffusion-MRI: Compartmentalized models in permeable cellular tissue
Rémy Gardier, Juan Luis Villarreal Haro, Erick J Canales-Rodrıguez +4
Diffusion-weighted magnetic resonance imaging (DW-MRI) is used to characterize brain tissue microstructure employing tissue-specific biophysical models. A current limitation, howev…
Considerations and recommendations from the ISMRM Diffusion Study Group for preclinical diffusion MRI: Part 2 -- Ex vivo imaging: added value and acquisition
Kurt G Schilling, Francesco Grussu, Andrada Ianus +54
The value of preclinical diffusion MRI (dMRI) is substantial. While dMRI enables in vivo non-invasive characterization of tissue, ex vivo dMRI is increasingly used to probe tissue…
Considerations and Recommendations from the ISMRM Diffusion Study Group for preclinical diffusion MRI: Part 1 -- In vivo small-animal imaging
Ileana O Jelescu, Francesco Grussu, Andrada Ianus +54
Small-animal diffusion MRI (dMRI) has been used for methodological development and validation, characterizing the biological basis of diffusion phenomena, and comparative anatomy.…
Neurite Exchange Imaging (NEXI): A minimal model of diffusion in gray matter with inter-compartment water exchange
Ileana O. Jelescu, Alexandre de Skowronski, Françoise Geffroy +2
Biophysical models of diffusion in white matter are based on what is now commonly referred to as the "Standard Model" (SM) of non-exchanging anisotropic Gaussian compartments. In t…
Intra- and extra-axonal axial diffusivities in the white matter: which one is faster?
Nicolas Kunz, Analina R. da Silva, Ileana O. Jelescu
A two-compartment model of diffusion in white matter, which accounts for intra- and extra-axonal spaces, is associated with two plausible mathematical scenarios: either the intra-a…
Rotationally-invariant mapping of scalar and orientational metrics of neuronal microstructure with diffusion MRI
Dmitry S. Novikov, Jelle Veraart, Ileana O. Jelescu +1
We develop a general analytical and numerical framework for estimating intra- and extra-neurite water fractions and diffusion coefficients, as well as neurite orientational dispers…
