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

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 impact of position-orientation adaptive smoothing in diffusion weighted imaging-From diffusion metrics to fiber tractography. [PDF]

PLoS ONE, 2020
In contrast to commonly used approaches to improve data quality in diffusion weighted imaging, position-orientation adaptive smoothing (POAS) provides an edge-preserving post-processing approach.

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.

Charting the Normal Development of Structural Brain Connectivity in Utero Using Diffusion MRI [PDF]

Human Brain Mapping, Volume 47, Issue 14, October 1, 2026.
This study proposes new methods to study the development of the structural connectivity in utero using diffusion‐weighted MRI. The methods are applied on data from around 200 fetal brains to chart how the structural connectome develops between 22 and 37 gestational weeks.

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.

Optic radiation fiber tractography in glioma patients based on high angular resolution diffusion imaging with compressed sensing compared with diffusion tensor imaging - initial experience. [PDF]

PLoS ONE, 2013
OBJECTIVE: Up to now, fiber tractography in the clinical routine is mostly based on diffusion tensor imaging (DTI). However, there are known drawbacks in the resolution of crossing or kissing fibers and in the vicinity of a tumor or edema.

Physical and digital phantoms for validating tractography and assessing artifacts

NeuroImage, 2021
Fiber tractography is widely used to non-invasively map white-matter bundles in vivo using diffusion-weighted magnetic resonance imaging (dMRI). As it is the case for all scientific methods, proper validation is a key prerequisite for the successful ...

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

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.
