An error analysis of probabilistic fibre tracking methods: average curves optimization [PDF]

, 2009
Fibre tractography using diffusion tensor imaging is a promising method for estimating the pathways of white matter tracts in the human brain. The success of fibre tracking methods ultimately depends upon the accuracy of the fibre tracking algorithms and

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.

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

Validating atlas-based lesion disconnectomics in multiple sclerosis: A retrospective multi-centric study

NeuroImage: Clinical, 2021
The translational potential of MR-based connectivity modelling is limited by the need for advanced diffusion imaging, which is not part of clinical protocols for many diseases.
