Prediction of muscle loss after stroke by analysis of corticospinal tract
Translational Neuroscience, 2020 Skeletal muscle loss induces a poor rehabilitation outcome after stroke. Little is known about the usefulness of diffusion tensor tractography (DTT) findings of the corticospinal tract (CST) in terms of predicting muscle loss in affected limbs after ...

Movement Disorders, EarlyView.Abstract Background Cognitive impairment is a prevalent and debilitating feature of Parkinson's disease (PD). Increasing evidence from postmortem and in vivo positron emission tomography imaging studies supports cholinergic dysfunction in PD. There is, however, little evidence regarding the influence of the structural integrity of cortical cholinergic ...

VIEW, EarlyView.In a cross‐sectional cohort of 104 participants, 7 T susceptibility separation MRI and diffusion imaging were combined with retinal imaging and visual evoked potentials to characterize visual pathway involvement in adrenomyeloneuropathy (AMN). Absolute diamagnetic susceptibility, a myelin‐associated measure, and fractional anisotropy (FA) showed ...

Clinical applications of diffusion tensor tractography of the spinal cord
Neuroradiology, 2007 Diffusion tensor imaging (DTI) can visualize the white matter tracts in vivo. The aim of this study was to assess the clinical utility of DTI in patients with diseases of the spinal cord. Fourteen subjects underwent magnetic resonance imaging of the spine at 1.5 T.

Tubes or Ribbons? Comparing Texture‐space Visualization for Multivariate Line Data
Computer Graphics Forum, EarlyView.Abstract Multivariate line data is critical for analyzing flow fields, agent systems, and dynamic trajectories. Embedding secondary variables along spatial paths using surface‐based primitives such as ribbons and circular tubes introduces challenges related to perspective, scale, and distortion.

Two-tensor Fiber Tractography [PDF]
, 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 ...

Developmental Medicine &Child Neurology, EarlyView.Normalized muscle volume remained unchanged in all evaluated muscles after the 12‐month treatment‐as‐usual in children with cerebral palsy. Higher intramuscular fat fraction was observed in the medial gastrocnemius, suggesting concurrent intramuscular fat infiltration.
