Beyond crossing fibers: Bootstrap probabilistic tractography using complex subvoxel fiber geometries [PDF]
Frontiers in Neurology, 2014 Diffusion magnetic resonance imaging fiber tractography is a powerful tool for investigating human white matter connectivity in vivo. However, it is prone to false positive and false negative results, making interpretation of the tractography result ...

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.

Mapping topographic structure in white matter pathways with level set trees.
PLoS ONE, 2014 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-

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.

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
