Tractography techniques map white matter bundles in the brain using diffusion magnetic resonance imaging (dMRI) data. These techniques use models to calculate paths where water molecule diffusion is least hindered, assuming these paths approximate the underlying white matter tracts, since diffusion is faster along tracts than across them.

Deterministic and Probabilistic Tractography Based on Complex Fibre Orientation Distributions [PDF]
IEEE Transactions on Medical Imaging, 2009 We propose an integral concept for tractography to describe crossing and splitting fibre bundles based on the fibre orientation distribution function (ODF) estimated from high angular resolution diffusion imaging (HARDI). We show that in order to perform accurate probabilistic tractography, one needs to use a fibre ODF estimation and not the diffusion ...

Probabilistic Tractography Using Lasso Bootstrap [PDF]
Medical Image Analysis, 2017 Diffusion magnetic resonance imaging (dMRI) can be used for noninvasive imaging of white matter tracts. Using fiber tracking, which propagates fiber streamlines according to fiber orientations (FOs) computed from dMRI, white matter tracts can be reconstructed for investigation of brain diseases and the brain connectome.

Probabilistic Tractography for Topographically Organized Connectomes [PDF]
Lecture Notes in Computer Science, 2016 While tractography is widely used in brain imaging research, its quantitative validation is highly difficult. Many fiber systems, however, have well-known topographic organization which can even be quantitatively mapped such as the retinotopy of visual pathway.

Structural Connectivity of the Human Massa Intermedia: A Probabilistic Tractography Study [PDF]
Human Brain Mapping, 2021 Abstract The role of massa intermedia (MI) is poorly understood in humans. Recent studies suggest its presence may play a role in normal human neurocognitive function while prior studies have shown the absence of MI correlated with psychiatric disorders.

Connectivity-based segmentation of the brainstem by probabilistic tractography [PDF]
Brain Research, 2018 Diffusion magnetic resonance imaging is a non-invasive tool increasingly used for the investigation of brain connectivity in vivo. In this paper we propose a method that allows segmentation of the brainstem to four subregions (frontopontine, motor, sensory and reticular) based on connections to supratentorial structures, thereby eliminating the need ...

Mapping Connectomes With Diffusion MRI: Deterministic or Probabilistic Tractography? [PDF]
Magnetic Resonance in Medicine, 2019 PURPOSE: Human connectomics necessitates high-throughput, whole-brain reconstruction of multiple white matter fiber bundles. Scaling up tractography to meet these high-throughput demands yields new fiber tracking challenges, such as minimizing spurious ...

The Role of Probabilistic Tractography in the Surgical Treatment of Thalamic Gliomas [PDF]
Operative Neurosurgery, 2014 Thalamic gliomas represent a great challenge for neurosurgeons because of the high surgical risk of damaging the surrounding anatomy. Preoperative planning may considerably help the surgeon find the most ideal operative trajectory, avoiding thalamic nuclei and important white matter pathways adjacent to the tumor tissue.
