Quantitative mapping of the brain’s structural connectivity using diffusion MRI tractography: A review

NeuroImage, 2022
Diffusion magnetic resonance imaging (dMRI) tractography is an advanced imaging technique that enables in vivo reconstruction of the brain’s white matter connections at macro scale.

Ensemble Tractography

PLOS Computational Biology, 2016
Tractography uses diffusion MRI to estimate the trajectory and cortical projection zones of white matter fascicles in the living human brain. There are many different tractography algorithms and each requires the user to set several parameters, such as curvature threshold. Choosing a single algorithm with specific parameters poses two challenges. First,

Diffusion Kurtosis Imaging Fiber Tractography of Major White Matter Tracts in Neurosurgery

Brain Sciences, 2021
Diffusion tensor imaging (DTI)-based fiber tractography is routinely used in clinical applications to visualize major white matter tracts, such as the corticospinal tract (CST), optic radiation (OR), and arcuate fascicle (AF).

The effects of the dialysis on the white matter tracts in patients with end-stage renal disease using differential tractography study

Scientific Reports, 2023
This study aimed to determine whether white matter tracts correlate with kidney function using correlation tractography, and to investigate the effects of dialysis on white matter tracts in patients with end-stage renal disease (ESRD) using differential ...

PopTract: Population-Based Tractography [PDF]

IEEE Transactions on Medical Imaging, 2011
White matter fiber tractography plays a key role in the in vivo understanding of brain circuitry. For tract-based comparison of a population of images, a common approach is to first generate an atlas by averaging, after spatial normalization, all images in the population, and then perform tractography using the constructed atlas.

Reconstruction of the arcuate fasciculus for surgical planning in the setting of peritumoral edema using two-tensor unscented Kalman filter tractography

NeuroImage: Clinical, 2015
Background: Diffusion imaging tractography is increasingly used to trace critical fiber tracts in brain tumor patients to reduce the risk of post-operative neurological deficit.

Implementation of clinical tractography for pre-surgical planning of space occupying lesions: An investigation of common acquisition and post-processing methods compared to dissection studies.

PLoS ONE, 2020
BACKGROUND AND PURPOSE:There is limited standardization of acquisition and processing methods in diffusion tractography for pre-surgical planning, leading to a range of approaches.

Measures for validation of DTI tractography [PDF]

SPIE Proceedings, 2012
The evaluation of analysis methods for diffusion tensor imaging (DTI) remains challenging due to the lack of gold standards and validation frameworks. Significant work remains in developing metrics for comparing fiber bundles generated from streamline tractography.

Magnetic resonance tractography exhibiting retrograde degeneration of the corticospinal tract in a patient with a unilateral spinal cord tumor

Brain and Behavior, 2021
Background Transection‐induced axonal retrograde degeneration, in contrast to Wallerian degeneration, has not been widely recognized in clinical practice.
