A site-wise reliability analysis of the ABCD diffusion fractional anisotropy and cortical thickness: impact of scanner platforms

The paper evaluates test-retest reliability of brain imaging metrics across multiple sites and scanners, finding significant differences in reliability between scanner types.

The influence of axonal beading and undulation on axonal diameter mapping

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

PyDesigner: A Pythonic Implementation of the DESIGNER Pipeline for Diffusion Tensor and Diffusional Kurtosis Imaging

PyDesigner is a Python package that preprocesses diffusion MRI data and estimates tensors, improving accuracy and robustness of diffusion and kurtosis metrics.

Multi-parametric quantitative spinal cord MRI with unified signal readout and image denoising

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.

Electron microscopy 3-dimensional segmentation and quantification of axonal dispersion and diameter distribution in mouse brain corpus callosum

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.

Spatial relationships between white matter degeneration, amyloid load and cortical volume in amnestic mild cognitive impairment

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.
