Diffusion Tensor Tractography in the Presurgical Assessment of Cerebral Gliomas [PDF]

The Neuroradiology Journal, 2014
Glioma is the most common intra-axial brain tumor characterized by invasion into the surrounding white matter (WM) tracts. These tumors are usually diagnosed by conventional MRI, but this method is unable to describe the relationship between tumor and neighboring WM tracts.

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 ...

Feasibility of 3.0 T diffusion-weighted nuclear magnetic resonance imaging in the evaluation of functional recovery of rats with complete spinal cord injury

Neural Regeneration Research, 2015
Diffusion tensor imaging is a sensitive way to reflect axonal necrosis and degeneration, glial cell regeneration and demyelination following spinal cord injury, and to display microstructure changes in the spinal cord in vivo.

Estimating the confidence level of white matter connections obtained with MRI tractography. [PDF]

PLoS ONE, 2008
BackgroundSince the emergence of diffusion tensor imaging, a lot of work has been done to better understand the properties of diffusion MRI tractography. However, the validation of the reconstructed fiber connections remains problematic in many respects.

A novel framework for in-vivo diffusion tensor distribution MRI of the human brain

NeuroImage, 2023
Neural tissue microstructure plays an important role in developmental, physiological and pathophysiological processes. Diffusion tensor distribution (DTD) MRI helps probe subvoxel heterogeneity by describing water diffusion within a voxel using an ...

The effects of the dialysis on the white matter tracts in patients with end-stage renal disease using differential tractography study

Scientific Reports, 2023
This study aimed to determine whether white matter tracts correlate with kidney function using correlation tractography, and to investigate the effects of dialysis on white matter tracts in patients with end-stage renal disease (ESRD) using differential ...

Diffusion tensor tractography in the preoperative precise identification of the course of facial nerve in a meningioma of the cerebellopontine angle – Technical implications

Interdisciplinary Neurosurgery, 2017
Background: Facial paralysis remains as one of the major morbidities of surgery of cerebellopontine angle tumors. The preoperative standard Magnetic Resonance Image does not identify, with precision, the path of the facial nerve.
