Reduced NEXI protocol for the quantification of human gray matter microstructure on the Connectome 2.0 scanner
Quentin Uhl, Tommaso Pavan, Julianna Gerold +10
Biophysical diffusion MRI models like Neurite Exchange Imaging (NEXI) are essential for probing gray matter microstructure, estimating compartment diffusivities, neurite fraction,…

Bayesian Insights into Exchange and Restriction in Gray Matter Diffusion MRI
Maëliss Jallais, Quentin Uhl, Tommaso Pavan +4
Biophysical models in diffusion MRI (dMRI) hold promise for characterizing gray matter tissue microstructure. Yet, the reliability of their parameter estimates remains largely unde…

Quantifying human gray matter microstructure using NEXI and 300 mT/m gradients
Quentin Uhl, Tommaso Pavan, Malwina Molendowska +3
Biophysical models of diffusion tailored to quantify gray matter microstructure are gathering increasing interest. The two-compartment Neurite EXchange Imaging () model has b…
