Validating Neurite EXchange Imaging (NEXI) using diffusion Monte Carlo simulations in realistic numerical gray matter substrates

This paper validates the NEXI model using diffusion Monte Carlo simulations in realistic gray matter substrates, showing it accurately recovers exchange times and disentangles exchange effects from microstructural features.

Validating the Standard Model of diffusion MRI in white matter with Numerical Substrates

This study evaluates the Standard Model of diffusion MRI in white matter by testing it on realistic numerical substrates, revealing how model estimates change under various biological conditions and noise levels.

In-vivo characterization of magnetic inclusions in the subcortex from non-exponential transverse relaxation decay

This paper demonstrates non-exponential transverse relaxation decay in human subcortical grey matter using MRI, enabling characterization of magnetic inclusions with potential applications in Parkinson's disease.

ISME - Incoherent Sampling of Multi-Echo data to minimize cardiac-induced noise in brain maps of R2* and magnetic susceptibility

The paper introduces ISME, a sampling strategy that reduces cardiac-induced noise in brain maps of R2* and magnetic susceptibility, improving reproducibility.

K-space sampling strategies to reduce noise induced by cardiac pulsatility in brain maps of R2* and magnetic susceptibility

The paper introduces two k-space sampling strategies to reduce cardiac-induced noise in MRI brain maps of R2* and magnetic susceptibility, showing improved variability reduction with one strategy.

Statistical analyses of motion-corrupted MRI relaxometry data

This paper introduces QUIQI, a method to restore homoscedasticity in MRI relaxometry data by using weighted least squares, improving statistical analysis robustness.

Single-subject EEG measurement of interhemispheric transfer-time for the in-vivo estimation of axonal morphology

This paper estimates axonal morphology from individual interhemispheric transfer time (IHTT) measurements obtained from single-subject EEG data, showing consistency with histological values but needing improved repeatability.

In-vivo estimation of axonal morphology from MRI and EEG data

This paper estimates axonal morphology from MRI and EEG data in humans, finding parameters consistent with histological findings.
