This paper demonstrates in vivo human brain neurite exchange imaging using a high-gradient MRI scanner, showing faster exchange times and spatial variation across cortical regions.

This study quantifies how axonal beading and undulation affect axon diameter estimation in diffusion MRI, showing potential biases up to 100% in pathological conditions.

This paper introduces a unified signal readout approach for multi-parametric spinal cord MRI, combined with MP-PCA denoising, improving the quality and consistency of microstructural metrics.

The paper segments and quantifies axonal dispersion and diameter in mouse brain corpus callosum using electron microscopy and a semi-automatic algorithm, showing orientation metrics are time-independent while diameter depends on MRI settings.

The paper examines spatial relationships between white matter degeneration, amyloid load, and cortical volume in amnestic mild cognitive impairment and finds that WM degeneration correlates more strongly with cortical volume than amyloid.
