Imaging versus electrographic connectivity in human mood-related fronto-temporal networks
Brain Stimulation, 2022 Background: The efficacy of psychiatric DBS is thought to be driven by the connectivity of stimulation targets with mood-relevant fronto-temporal networks, which is typically evaluated using diffusion-weighted tractography.

TWO-TENSOR FIBER TRACTOGRAPHY [PDF]
2007 4th IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2007 Estimating white matter fiber pathways from a diffusion tensor MRI dataset has many important applications in medical research. However, the standard approach of performing tracking on single-tensor estimates per voxel is confounded by regions of multiple pathways in different directions.

Diffusion Kurtosis Imaging Fiber Tractography of Major White Matter Tracts in Neurosurgery
Brain Sciences, 2021 Diffusion tensor imaging (DTI)-based fiber tractography is routinely used in clinical applications to visualize major white matter tracts, such as the corticospinal tract (CST), optic radiation (OR), and arcuate fascicle (AF).

PLOS Computational Biology, 2016 Tractography uses diffusion MRI to estimate the trajectory and cortical projection zones of white matter fascicles in the living human brain. There are many different tractography algorithms and each requires the user to set several parameters, such as curvature threshold. Choosing a single algorithm with specific parameters poses two challenges. First,

PopTract: Population-Based Tractography [PDF]
IEEE Transactions on Medical Imaging, 2011 White matter fiber tractography plays a key role in the in vivo understanding of brain circuitry. For tract-based comparison of a population of images, a common approach is to first generate an atlas by averaging, after spatial normalization, all images in the population, and then perform tractography using the constructed atlas.

NeuroImage, 2018 Tractography based on diffusion-weighted MRI investigates the large scale arrangement of the neurite fibers in brain white matter. It is usually assumed that the signal is a convolution of a fiber specific response function (FRF) with a fiber orientation distribution (FOD). The FOD is the focus of tractography.
