The paper introduces a convolutional autoencoder framework to map and visualize white matter deformation in glioma patients using diffusion MRI data.

HARP: Hierarchical Anatomical Refinement of Pathways for Whole-Brain Tractography

HARP improves diffusion MRI tractography by integrating hierarchical anatomical constraints, reducing implausible streamlines by up to 9%.

Distinct cortical excitability and connectivity profiles within the human SMA complex

This study identifies distinct neurophysiological and structural connectivity profiles in the human SMA complex using TMS-EEG and diffusion-weighted connectomics.

Optimization of TMS target engagement: novel evidence based on combined TMS-EEG and dMRI tractography of brain circuitry

The paper presents novel data using dMRI tractography-guided TMS-EEG on a single healthy young adult to better understand brain circuitry engagement during neuromodulation.

Real-time tractography-assisted neuronavigation for TMS

This paper develops a real-time tractography-assisted TMS neuronavigation system and demonstrates its feasibility through comparison with offline tractography results.

Insights from the IronTract challenge: optimal methods for mapping brain pathways from multi-shell diffusion MRI

The paper evaluates tractography methods using a macaque dataset to determine optimal approaches for mapping brain pathways from multi-shell diffusion MRI.

Tractography dissection variability: what happens when 42 groups dissect 14 white matter bundles on the same dataset?

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

Tractography Reproducibility Challenge with Empirical Data (TraCED): The 2017 ISMRM Diffusion Study Group Challenge

The paper evaluates tractography reproducibility using empirical data from a single healthy volunteer scanned on two scanners, finding high consistency among top algorithms but variability due to tract volume containment.

Limits to anatomical accuracy of diffusion tractography using modern approaches

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