Maturation and interhemispheric asymmetry in neurite density and orientation dispersion in early childhood

This study uses NODDI to examine age-related changes in neurite density and orientation dispersion in children's white matter, finding increases in density but no change in dispersion.

Early childhood development of white matter fiber density and morphology

The paper quantifies white matter development in early childhood using fixel-based analysis and finds greater morphological than microstructural changes.

Modulation of white matter bundle connectivity in the presence of axonal truncation pathologies

The paper proposes a method to correct over-estimation of white matter bundle connectivity in diffusion MRI when axons are truncated due to pathology.

MRtrix3: A fast, flexible and open software framework for medical image processing and visualisation

MRtrix3 provides an open-source C++11 and Python software framework, command-line suite, and OpenGL 3.3 viewer for fast multi-dimensional medical image processing and diffusion MRI analysis.

In vivo microstructural heterogeneity of white matter lesions in Alzheimer’s disease using tissue compositional analysis of diffusion MRI data

This study uses diffusion MRI to analyze microstructural heterogeneity in white matter lesions of Alzheimer’s disease patients, revealing differences in tissue composition between lesion types and their proximity to ventricles.

Is removal of weak connections necessary for graph-theoretical analysis of dense weighted structural connectomes?

The paper evaluates whether removing weak connections from dense weighted structural connectomes is necessary for graph-theoretical analysis and finds it is not required.
