Diffusion Tractography Biomarkers of Pediatric Cerebellar Hypoplasia/Atrophy: Preliminary Results Using Constrained Spherical Deconvolution. [PDF]

AJNR Am J Neuroradiol, 2016
Advances in MR imaging modeling have improved the feasibility of reconstructing crossing fibers, with increasing benefits in delineating angulated tracts such as cerebellar tracts by using tractography.

Constrained spherical deconvolution on diffusion-weighted images of dolphin brains [PDF]

Magnetic Resonance Imaging
Invasive neuronal tract-tracing is not permitted in very large or endangered animals. This is especially the case in marine mammals like dolphins. Diffusion-weighted imaging of fiber tracts could be an alternative if feasible even in brains that have ...

Red nucleus connectivity as revealed by constrained spherical deconvolution tractography

Neuroscience Letters, 2016
Previous Diffusion Tensor Imaging studies have demonstrated that the human red nucleus is widely interconnected with sensory-motor and prefrontal cortices.In this study, we assessed red nucleus connectivity by using a multi-tensor model called non ...

A Fiber Tracking Algorithm Based on Non-Local Constrained Spherical Deconvolution

Chinese Journal of Magnetic Resonance, 2020
Fiber tracking with diffusion magnetic resonance imaging provides a powerful tool for non-invasive observation of white matter in the brain. Constrained spherical deconvolution (CSD) is a multi-fiber tracking model, which can model the orientation of ...

Improvement in White Matter Tract Reconstruction with Constrained Spherical Deconvolution and Track Density Mapping in Low Angular Resolution Data: A Pediatric Study and Literature Review [PDF]

Frontiers in Pediatrics, 2017
IntroductionDiffusion-weighted magnetic resonance imaging (DW-MRI) allows noninvasive investigation of brain structure in vivo. Diffusion tensor imaging (DTI) is a frequently used application of DW-MRI that assumes a single main diffusion direction per ...

Connectome analysis with diffusion MRI in idiopathic Parkinson's disease: Evaluation using multi-shell, multi-tissue, constrained spherical deconvolution [PDF]

NeuroImage: Clinical, 2018
Parkinson's disease (PD) is a progressive neurodegenerative disorder that affects extensive regions of the central nervous system. In this work, we evaluated the structural connectome of patients with PD, as mapped by diffusion-weighted MRI tractography ...

White matter organization in developmental coordination disorder: A pilot study exploring the added value of constrained spherical deconvolution [PDF]

NeuroImage: Clinical, 2019
Previous studies of white matter organization in sensorimotor tracts in developmental coordination disorder (DCD) have adopted diffusion tensor imaging (DTI), a method unable to reconcile pathways with ‘crossing fibres’. In response to limitations of the

Constrained Spherical Deconvolution Tractography Reveals Cerebello-Mammillary Connections in Humans

The Cerebellum, 2017
According to the classical view, the cerebellum has long been confined to motor control physiology; however, it has now become evident that it exerts several non-somatic features other than the coordination of movement and is engaged also in the ...
