Connectivity-enhanced diffusion analysis reveals white matter density disruptions in first episode and chronic schizophrenia. [PDF]
, 2018 Reduced fractional anisotropy (FA) is a well-established correlate of schizophrenia, but it remains unclear whether these tensor-based differences are the result of axon damage and/or organizational changes and whether the changes are progressive in the ...

Multi-Fiber Tractography Visualizations for Diffusion MRI Data
PLoS ONE, 2013 In recent years, several new diffusion MRI approaches have been proposed to explore microstructural properties of the white matter, such as Q-ball imaging and spherical deconvolution-based techniques to estimate the orientation distribution function.

Diffusion Tensor MR Imaging and Fiber Tractography: Technical Considerations [PDF]
American Journal of Neuroradiology, 2008 This second article of the 2-part review builds on the theoretic background provided by the first article to cover the major technical factors that affect image quality in diffusion imaging, including the acquisition sequence, magnet field strength, gradient amplitude, and slew rate as well as multichannel radio-frequency coils and parallel imaging ...

Automated white matter fiber tract identification in patients with brain tumors
NeuroImage: Clinical, 2017 We propose a method for the automated identification of key white matter fiber tracts for neurosurgical planning, and we apply the method in a retrospective study of 18 consecutive neurosurgical patients with brain tumors.

Limbic Tract Integrity Contributes to Pattern Separation Performance Across the Lifespan. [PDF]
, 2014 Accurate memory for discrete events is thought to rely on pattern separation to orthogonalize the representations of similar events. Previously, we reported that a behavioral index of pattern separation was correlated with activity in the hippocampus ...

DTI Image Registration under Probabilistic Fiber Bundles Tractography Learning [PDF]
BioMed Research International, 2016 Diffusion Tensor Imaging (DTI) image registration is an essential step for diffusion tensor image analysis. Most of the fiber bundle based registration algorithms use deterministic fiber tracking technique to get the white matter fiber bundles, which will be affected by the noise and volume.

Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Background and Objectives Multiple sclerosis (MS) exhibits racially disparate rates of disease progression. Black people with MS (B‐PwMS) experience a more severe disease course than non‐Hispanic White people with MS (NHW‐PwMS). Here we investigated structural and functional connectivity as well as structure–function decoupling in the ...
