Comparative mouse brain tractography of diffusion magnetic resonance imaging

Diffusion magnetic resonance imaging (dMRI) tractography can be employed to simultaneously analyze three-dimensional white matter tracts in the brain. Numerous methods have been proposed to model diffusion-weighted magnetic resonance data for tractography, and we have explored the functionality of some of these for studying white and grey matter pathways in ex vivo mouse brain. Using various de...

A Novel Average Curves Tractography Technique - Validation Using a Physical Phantom

Introduction Probabilistic tractography methods have been developed as an alternative to deterministic algorithms due to their ability to handle the uncertainty of fibre orientations. However, deterministic tractography have several advantages over probabilistic tractography for some applications such as neurosurgery. Visualization of the deterministic streamline trajectories is similar to the ...

Comparison of probabilistic diffusion tensor tractography and histological tracer studies in the rhesus macaque

Examinations of probabilistic tractography have identified major tracts across the brain, but little has been done to compare them to wellestablished tracer studies. Therefore, diffusion tensor imaging (DTI) probabilistic tractography of white matter (WM) was performed on a DTI template generated from 271 rhesus macaques. Injection sites from tracer experiments in literature were chosen as seed...

A robust method for investigating thalamic white matter tracts after traumatic brain injury

Damage to the structural connections of the thalamus is a frequent feature of traumatic brain injury (TBI) and can be a key factor in determining clinical outcome. Until recently it has been difficult to quantify the extent of this damage in vivo. Diffusion tensor imaging (DTI) provides a validated method to investigate traumatic axonal injury, and can be applied to quantify damage to thalamic ...

Probabilistic atlases of default mode, executive control and salience network white matter tracts: an fMRI-guided diffusion tensor imaging and tractography study

Diffusion tensor imaging (DTI) is a powerful MRI technique that can be used to estimate both the microstructural integrity and the trajectories of white matter pathways throughout the central nervous system. This fiber tracking (aka, "tractography") approach is often carried out using anatomically-defined seed points to identify white matter tracts that pass through one or more structures, but ...
