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.

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.

Diffusion tensor imaging reveals sex differences in pain sensitivity of rats

Frontiers in Molecular Neuroscience, 2023
Studies on differences in brain structure and function according to sex are reported to contribute to differences in behavior and cognition. However, few studies have investigated brain structures or used tractography to investigate gender differences in

Validation of in utero tractography of human fetal commissural and internal capsule fibers with histological structure tensor analysis

Frontiers in Neuroanatomy, 2015
Diffusion tensor imaging (DTI) and tractography offer the unique possibility to visualize the developing white matter macroanatomy of the human fetal brain in vivo and in utero and are currently under investigation for their potential use in the ...

Validate your white matter tractography algorithms with a reappraised ISMRM 2015 Tractography Challenge scoring system

Scientific Reports, 2023
Since 2015, research groups have sought to produce the ne plus ultra of tractography algorithms using the ISMRM 2015 Tractography Challenge as evaluation. In particular, since 2017, machine learning has made its entrance into the tractography world.

Using mesoscopic tract-tracing data to guide the estimation of fiber orientation distributions in the mouse brain from diffusion MRI

NeuroImage, 2023
Diffusion MRI (dMRI) tractography is the only tool for non-invasive mapping of macroscopic structural connectivity over the entire brain. Although it has been successfully used to reconstruct large white matter tracts in the human and animal brains, the ...

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.

Optic Radiation Tractography in Pediatric Brain Surgery Applications: A Reliability and Agreement Assessment of the Tractography Method

Frontiers in Neuroscience, 2019
BackgroundOptic radiation (OR) tractography may help predict and reduce post-neurosurgical visual field deficits. OR tractography methods currently lack pediatric and surgical focus.PurposeWe propose a clinically feasible OR tractography strategy in a ...

Motor Evoked Potentials Improve Targeting in Deep Brain Stimulation Surgery

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives One of the main challenges posed by the surgical deep brain stimulation (DBS) procedure is the successful targeting of the structures of interest and avoidance of side effects, especially in asleep surgery. Here, intraoperative motor evoked potentials (MEPs) might serve as tool to identify the pyramidal tract.

CTtrack: A CNN+Transformer-based framework for fiber orientation estimation & tractography

Neuroscience Informatics, 2022
In recent years, multiple data-driven fiber orientation distribution function (fODF) estimation algorithms and automatic tractography pipelines have been proposed to address the limitations of traditional methods. However, these approaches lack precision
