Anisotropic Anomalous Diffusion assessed in the human brain by scalar invariant indices

, 2010
A new method to investigate anomalous diffusion in human brain is proposed. The method has been inspired by both the stretched-exponential model proposed by Hall and Barrick (HB) and DTI.

Clinical and Radiological Evolution of Idiopathic Normal Pressure Hydrocephalus: A Critical Review

Movement Disorders Clinical Practice, EarlyView.
Abstract Background The pathophysiology of idiopathic normal pressure hydrocephalus (iNPH) remains poorly understood. While it is commonly accepted that iNPH has an insidious onset, little is known about its preclinical and early stages and its development over time.

Diffusion tensor tractography in children with sensory processing disorder: potentials for devising machine learning classifiers [PDF]

, 2019
The “sensory processing disorder” (SPD) refers to brain's inability to organize sensory input for appropriate use. In this study, we determined the diffusion tensor imaging (DTI) microstructural and connectivity correlates of SPD, and apply machine ...

Accelerating Multiparametric Quantitative MRI Using Self‐Supervised Scan‐Specific Implicit Neural Representation With Model Reinforcement

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a self‐supervised scan‐specific deep learning framework for reconstructing accelerated multiparametric quantitative MRI (qMRI). Methods We propose REFINE‐MORE (REference‐Free Implicit NEural representation with MOdel REinforcement), combining an implicit neural representation (INR) architecture with a model reinforcement ...

Early Brain Loss in Circuits Affected by Alzheimer’s Disease is Predicted by Fornix Microstructure but may be Independent of Gray Matter [PDF]

, 2014
In a cohort of community-recruited elderly subjects with normal cognition at initial evaluation, we found that baseline fornix white matter (WM) microstructure was significantly correlated with early volumetric longitudinal tissue change across a region ...

Transient Edematous Lesions of the Splenium in Epileptic Patients [PDF]

Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 2005
ABSTRACT:Background:Transient focal lesions in the splenium of the corpus callosum (SCC) have been previously described in patients with epilepsy or without epilepsy but receiving antiepileptic drugs (AED).Case reports:Two epileptic patients were admitted to our long-term monitoring unit.
