Diffusion MRI Harmonization via Personalized Template Mapping

This paper introduces a personalized template mapping framework for diffusion MRI harmonization, improving performance over existing methods by preserving biological variability and reducing scanner-related differences.

Vessel Density Mapping of Cerebral Small Vessels on 3D High Resolution Black Blood MRI

This paper introduces a pipeline for mapping cerebral small vessel density using 3D black-blood MRI, finding higher density in young subjects and correlations with cognitive scores in aged subjects.

Retinal ganglion cell endowment is correlated with optic tract fiber cross section, not density

The paper finds that retinal ganglion cell endowment correlates with optic tract cross section, not density, and that anatomical variations are locally correlated along the visual pathway.

Probabilistic Tracking U-fiber on the Superficial White Matter Surface

This paper introduces a surface-based probabilistic tractography method for reconstructing U-fibers in the superficial white matter, showing improved accuracy compared to volume-based and other surface-based methods.

Age Differences in Diffusivity in the Locus Coeruleus and its Ascending Noradrenergic Tract

The paper examines age-related differences in fractional anisotropy in the locus coeruleus and its ascending noradrenergic tract using diffusion-weighted MRI across three datasets.

Hippocampal Asymmetry of Regional Development and Structural Covariance in Preterm Neonates

This study compares hippocampal development in preterm and term-born neonates using MRI, finding asymmetrical structural impairments in preterm infants.

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.

Mapping Complex Brain Torque Components and Their Genetic and Phenomic Architecture in 24,112 healthy individuals

This study analyzes brain torque components in 24,112 individuals, finding sex/handedness differences, heritability up to 56%, and genome- and phenome-wide associations with various traits.

A Measure of Whole-Brain White Matter Topography

The paper develops a measure of whole-brain white matter topography using diffusion MRI data and finds it correlates with tractogram streamlines.

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.
