Merged Group Tractography Evaluation with Selective Automated Group Integrated Tractography (SAGIT) [PDF]

Frontiers in Neuroanatomy, 2016
Introduction: Tractography analysis in group-based studies across large populations is difficult to manage and assess. We propose Selective Automated Group Integrated Tractography (SAGIT), an automated group tractography software platform that ...

Toward global tractography

NeuroImage, 2013
Diffusion-based tractography is an ill-posed problem, because the step-by-step reconstruction of a fibre bundle trajectory cannot afford any serious mistake in the evaluation of the local fibre orientations. Such evaluation is difficult, however, because the myriad fibres passing through a single voxel follow different directions.

Surface-enhanced tractography (SET)

NeuroImage, 2018
In this work, we exploit the T1 weighted image in conjunction with cortical surface boundary to improve the precision of tractography under the cortex. We show that utilizing the cortical interface and a surface flow, to model the superficial white matter streamlines, enhance and improve tractography trajectory near the cortex.

Tractography methods and findings in brain tumors and traumatic brain injury

NeuroImage, 2021
White matter fiber tracking using diffusion magnetic resonance imaging (dMRI) provides a noninvasive approach to map brain connections, but improving anatomical accuracy has been a significant challenge since the birth of tractography methods.

Three-Dimensional Identification of the Frontal Aslant Tract in the Human Brain: Tractography Study [PDF]

Brain Sciences
Background: The frontal aslant tract (FAT) is a white matter pathway associated with language and executive functions. The aim of the study was to identify and analyze this tract using DTI tractography.

Hierarchical Microstructure Informed Tractography [PDF]

Brain Connectivity, 2021
Background: Tractography uses diffusion magnetic resonance imaging to noninvasively infer the macroscopic pathways of white matter fibers and it is the only available technique to probe in vivo the structural connectivity of the brain. However, despite this unique and compelling ability and its wide range of possible neurological applications ...

White matter tractography for neurosurgical planning: A topography-based review of the current state of the art

NeuroImage: Clinical, 2017
We perform a review of the literature in the field of white matter tractography for neurosurgical planning, focusing on those works where tractography was correlated with clinical information such as patient outcome, clinical functional testing, or ...

Millennium Pathways for Tractography: 40 grand challenges to shape the future of tractography

ArXiv
In the spirit of the historic Millennium Prize Problems that heralded a new era for mathematics, the newly formed International Society for Tractography (IST) has launched the Millennium Pathways for Tractography, a community-driven roadmap designed to shape the future of the field.

A rapid streamline-based extension of Tractfinder for white matter tract segmentation [PDF]

Frontiers in Neuroimaging
Accurate delineation of white matter tracts is critical in the pre-operative assessment of paediatric brain tumour patients, where preservation of eloquent pathways directly influences surgical planning and functional outcomes.

Weakening of Subcortical and Strengthening of Cortical Visual Pathways Across Early Adolescence [PDF]

Human Brain Mapping, Volume 47, Issue 13, September 2026.
Longitudinal diffusion MRI in 4361 adolescents shows weakening of visual subcortical pathways but strengthening of cortical pathways over pubertal development. ABSTRACT Mounting evidence suggests that amygdalar nuclei receive visual information via both a well‐characterized cortical pathway through the inferior temporal cortex and a subcortical route ...
