Estimation of free water-corrected microscopic fractional anisotropy [PDF]
Frontiers in Neuroscience, 2023 Water diffusion anisotropy MRI is sensitive to microstructural changes in the brain that are hallmarks of various neurological conditions. However, conventional metrics like fractional anisotropy are confounded by neuron fiber orientation dispersion, and

FRACTIONAL ANISOTROPY OF THE FORNIX AND HIPPOCAMPAL ATROPHY IN ALZHEIMER’S DISEASE [PDF]
Frontiers in Aging Neuroscience, 2014 Decrease in the directionality of water diffusion measured with fractional anisotropy on diffusion tensor imaging has been linked to loss of myelin and axons in the white matter.

Microscopic fractional anisotropy outperforms multiple sclerosis lesion assessment and clinical outcome associations over standard fractional anisotropy tensor. [PDF]
Hum Brain MappAbstractWe aimed to compare the ability of diffusion tensor imaging and multi‐compartment spherical mean technique to detect focal tissue damage and in distinguishing between different connectivity patterns associated with varying clinical outcomes in multiple sclerosis (MS).

Developmental and regional dependence of macromolecular proton fraction and fractional anisotropy in fixed brain tissue. [PDF]
NMR Biomed, 2023 An important advantage of imaging fixed tissue is a gain in signal‐to‐noise ratio and in resolution due to unlimited scan time. However, the fidelity of quantitative MRI parameters in fixed brain tissue, particularly in developmental settings, requires validation.

Comprehensive analysis of early fractional anisotropy changes in acute ischemic stroke. [PDF]
PLoS ONE, 2017 Cerebral ischemia leads to a rapid decrease of the apparent diffusion coefficient. For fractional anisotropy both increase and decrease have been reported in acute ischemic stroke.

Age differences in diffusivity in the locus coeruleus and its ascending noradrenergic tract
NeuroImage, 2022 The noradrenergic locus coeruleus (LC) is a small brainstem nucleus that promotes arousal and attention. Recent studies have examined the microstructural properties of the LC using diffusion-weighted magnetic resonance imaging and found unexpected age ...
