This study analyzes diffusion MRI data from 1184 participants to quantify age-related changes in white matter microstructure and macrostructure, finding that macrostructural features show more heterogeneous age-related decline.

This study evaluates variability in white matter bundle segmentation across 42 groups using the same dataset, finding protocol variability exceeds other sources of inconsistency.

This study evaluates how scanner, vendor, resolution, diffusion scheme, and segmentation workflow variations affect diffusion tractography bundle segmentation results.

This paper introduces an empirical method to correct gradient nonlinearity in multi-site diffusion weighted MRI, improving reproducibility across scanners and sessions.

The paper presents a population-based white matter atlas derived from diffusion MRI fiber tractography, including 216 bundles from 2443 subjects.

TractEM provides manual labeling protocols for white matter tractography to improve reproducibility and accuracy in brain connectivity studies.

This study evaluates modern diffusion tractography methods using a standardized challenge, finding no significant improvement in anatomical accuracy despite methodological advances.
