Entrack: Probabilistic Spherical Regression with Entropy Regularization for Fiber Tractography [PDF]

International Journal of Computer Vision, 2020
AbstractWhite matter tractography, based on diffusion-weighted magnetic resonance images, is currently the only available in vivo method to gather information on the structural brain connectivity. The low resolution of diffusion MRI data suggests to employ probabilistic methods for streamline reconstruction, i.e., for fiber crossings.

Target identification for stereotactic thalamotomy using diffusion tractography. [PDF]

PLoS ONE, 2012
BACKGROUND: Stereotactic targets for thalamotomy are usually derived from population-based coordinates. Individual anatomy is used only to scale the coordinates based on the location of some internal guide points.

White matter tract-specific quantitative analysis in multiple sclerosis: Comparison of optic radiation reconstruction techniques. [PDF]

PLoS ONE, 2018
The posterior visual pathway is commonly affected by multiple sclerosis (MS) pathology that results in measurable clinical and electrophysiological impairment.

Diffusion MRI and anatomic tracing in the same brain reveal common failure modes of tractography

NeuroImage, 2021
Anatomic tracing is recognized as a critical source of knowledge on brain circuitry that can be used to assess the accuracy of diffusion MRI (dMRI) tractography.

Superficial white matter bundle atlas based on hierarchical fiber clustering over probabilistic tractography data

NeuroImage, 2022
The study of short association fibers is still an incomplete task due to their higher inter-subject variability and the smaller size of this kind of fibers in comparison to known long association bundles.

Combining tractography and cortical measures to test system-specific hypotheses in multiple sclerosis. [PDF]

, 2010
The objective was to test three motor system-specific hypotheses in multiple sclerosis patients: (i) corticospinal tract and primary motor cortex imaging measures differ between multiple sclerosis patients and controls; (ii) in patients, these measures ...

Geodesic Uncertainty in Diffusion MRI

Frontiers in Computer Science, 2021
We study theoretical and operational issues of geodesic tractography, a geometric methodology for retrieving biologically plausible neural fibers in the brain from diffusion weighted magnetic resonance imaging.

Defining Meyer's loop-temporal lobe resections, visual field deficits and diffusion tensor tractography [PDF]

, 2009
Anterior temporal lobe resection is often complicated by superior quadrantic visual field deficits (VFDs). In some cases this can be severe enough to prohibit driving, even if a patient is free of seizures.

Probabilistic functional tractography of the human cortex revisited

NeuroImage, 2018
In patients with pharmaco-resistant focal epilepsies investigated with intracranial electroencephalography (iEEG), direct electrical stimulations of a cortical region induce cortico-cortical evoked potentials (CCEP) in distant cerebral cortex, which properties can be used to infer large scale brain connectivity. In 2013, we proposed a new probabilistic
