MRtrix: Diffusion tractography in crossing fiber regions
TL;DR: This methodology is shown to provide superior delineations of a number of known white matter tracts, in a manner robust to crossing fiber effects, and has been compiled into a software package, called MRtrix, which has been made freely available for use by the scientific community.
Journal ArticleDOI
Fibre-specific white matter reductions in Alzheimer's disease and mild cognitive impairment.
Remika Mito,Remika Mito,David Raffelt,Thijs Dhollander,David N. Vaughan,David N. Vaughan,J-Donald Tournier,Olivier Salvado,Amy Brodtmann,Amy Brodtmann,Amy Brodtmann,Christopher C. Rowe,Victor L. Villemagne,Victor L. Villemagne,Alan Connelly,Alan Connelly +15 more
TL;DR: A stereotypical distribution of white matter degeneration in patients with Alzheimer's disease was demonstrated, which was in line with canonical findings from other imaging modalities, and with a network-based conceptualization of the disease.
Estimating the number of fiber orientations in diffusion MRI voxels : a constrained spherical deconvolution study
TL;DR: In this paper, the number of fiber orientations within each voxel using constrained spherical deconvolution (CSD) with the residual bootstrap approach was estimated using a Bayesian Automatic Relevance Determination (ARD) method.

TL;DR: Greater and more extensive deviations were associated with more extreme prematurity and predicted poorer cognitive and language abilities at 18 months, and poorly understood heterogeneity likely relates to both the etiology and prognosis of brain injury.

Scattered slice SHARD reconstruction for motion correction in multi-shell diffusion MRI of the neonatal brain
Daan Christiaens,Lucilio Cordero-Grande,Maximilian Pietsch,Jana Hutter,Anthony N. Price,Emer Hughes,Katy Vecchiato,Maria Deprez,A. David Edwards,Joseph V. Hajnal,J-Donald Tournier +10 more
TL;DR: A slice-to-volume reconstruction framework for multi-shell HARDI data is introduced based on a data-driven representation as spherical harmonics and radial decomposition (SHARD) and results show robust reconstruction in severely motion-corrupted scans.
