Regional Brain Volume Differences Were Associated With Behavioural Outcomes in Children Born Preterm: A Systematic Review

open access: yesActa Paediatrica, EarlyView.
ABSTRACT Aim This systematic review explored associations between brain structural volumes and behavioural outcomes in children born preterm up to 32 weeks of gestation. Methods PubMed, PsycINFO, Scopus and Web of Science were searched for papers published in English from 1 January 2013 to 7 November 2023.

Validation of in vitro probabilistic tractography

open access: yesNeuroImage, 2007
Diffusion weighted imaging (DWI) and tractography allow the non-invasive study of anatomical brain connectivity. However, a gold standard for validating tractography of complex connections is lacking. Using the porcine brain as a highly gyrated brain model, we quantitatively and qualitatively assessed the anatomical validity and reproducibility of in ...

Addressing the path-length-dependency confound in white matter tract segmentation.

open access: yesPLoS ONE, 2014
We derive the Iterative Confidence Enhancement of Tractography (ICE-T) framework to address the problem of path-length dependency (PLD), the streamline dispersivity confound inherent to probabilistic tractography methods.

Mapping Topographic Structure in White Matter Pathways with Level Set Trees

open access: yes
Fiber tractography on diffusion imaging data offers rich potential for describing white matter pathways in the human brain, but characterizing the spatial organization in these large and complex data sets remains a challenge. We show that level set trees-

Altered white matter structure in auditory tracts following early monocular enucleation [PDF]

open access: yes
Purpose: Similar to early blindness, monocular enucleation (the removal of one eye) early in life results in crossmodal behavioral and morphological adaptations.

Real‐Time Rendering of Dynamic Line Sets using Voxel Ray Tracing

open access: yesComputer Graphics Forum, EarlyView.
Abstract Real‐time rendering of dynamic line sets is relevant in many visualization tasks, including unsteady flow visualization and interactive white matter reconstruction from Magnetic Resonance Imaging. High‐quality global illumination and transparency are important for conveying the spatial structure of dense line sets, yet remain difficult to ...

An error analysis of probabilistic fibre tracking methods: average curves optimization [PDF]

open access: yes
Fibre tractography using diffusion tensor imaging is a promising method for estimating the pathways of white matter tracts in the human brain. The success of fibre tracking methods ultimately depends upon the accuracy of the fibre tracking algorithms and

Directionality of longitudinal associations between frontostriatal structural connectivity and depressive symptoms in adolescent girls

open access: yesJournal of Child Psychology and Psychiatry, EarlyView.
Background Individual differences in the structure and function of the frontostriatal reward network have been related to depression. However, there is a strong need for prospective, longitudinal studies aiming to understand the role of frontostriatal networks in depression in a developmental context.

Massive Particles for Brain Tractography [PDF]

open access: yes, 2010
We propose a method for estimating axonal fiber connectivity pathways (cerebral connectivity fibers) from Multi-Tensor Diffusion Magnetic Resonance Imaging (MTD-MRI). Our method uses multiple local orientation information provided by MTD-MRI for leading stochastic walks of particles.

The challenge of mapping the human connectome based on diffusion tractography

open access: yesNature Communications, 2017
Though tractography is widely used, it has not been systematically validated. Here, authors report results from 20 groups showing that many tractography algorithms produce both valid and invalid bundles.
