Navigational skills correlate with hippocampal fractional anisotropy in humans
Hippocampus, 2008AbstractIndividuals vary widely in their ability to orient within the environment. We used diffusion tensor imaging to investigate whether this ability, as measured by navigational performance in a virtual environment, correlates with the anatomic structural properties of the hippocampus, i.e., fractional anisotropy. We found that individuals with high

Fractional anisotropy and diffusivity changes in thyroid-associated orbitopathy
Neuroradiology, 2016To investigate the extraocular muscle (EOM) changes in thyroid-associated orbitopathy (TAO) on DTI and the correlations between DTI parameters and clinical features.Twenty TAO patients and 20 age- and sex-matched controls provided informed consent and were enrolled. Ten-directional DTI was acquired in orbit. Fractional anisotropy (FA), mean, axial, and

Fractional Anisotropy in Three Variants of Primary Progressive Aphasia
European Neurology, 2012<b><i>Objective:</i></b> Our aim was to report diffusion tensor imaging (DTI) patterns in three patients, each with a different primary progressive aphasia (PPA) variant. <b><i>Design:</i></b> One agrammatic PPA, one semantic PPA, and one logopenic PPA subject underwent a magnetic resonance imaging ...

FRACTIONAL DIFFUSION-LIMITED AGGREGATION: ANISOTROPY ORIGINATING FROM MEMORY
Fractals, 2019This paper introduces a modified DLA model, based on a fractional diffusion mechanism, as a novel approach to modeling fractal growth. The specific memory performance of fractional operators can be reflected macroscopically in aggregated patterns eventually.

ISMRM Annual Meeting
In previous studies average values of Apparent Diffusion Coefficient (ADC) have been shown to change significantly after radiotherapy in Soft-Tissue Sarcomas (STS). In this study we evaluate the Fractional Anisotropy (FA) of STS before and after treatment and demonstrate that (i) tumours can exhibit significant diffusion anisotropy, and (ii) changes in

Microscopic fractional anisotropy with free water elimination
ISMRM Annual MeetingWater diffusion anisotropy is a diffusion MRI metric that is sensitive to brain injury and neurodegeneration. Microscopic fractional anisotropy (μFA) is a new metric of diffusion anisotropy that is immune to crossing fiber effects, unlike traditional FA, which enables probing of axon integrity in gray matter and crossing white matter tracts.

Reliability of Fractional Anisotropy Measurement for Children with Cerebral Palsy
Neuropediatrics, 2013Periventricular leukomalacia (PVL) is the leading cause of disability in children with cerebral palsy (CP). Diffusion tensor imaging (DTI) is a magnetic resonance imaging technique for detecting microstructural lesions of white matter. Fractional anisotropy (FA) is a widely used DTI index with clinical significance in children with CP.
