Fractional Anisotropy - an overview ScienceDirect Topic

Fractional anisotropy. Aus Wikipedia, der freien Enzyklopädie. Die fraktionelle Anisotropie (FA) ist ein Skalarwert zwischen Null und Eins, der den Grad der Anisotropie eines Diffusionsprozesses beschreibt . Ein Wert von Null bedeutet, dass die Diffusion isotrop ist, dh sie ist in alle Richtungen uneingeschränkt (oder gleichermaßen eingeschränkt) Fractional anisotropy is a method that is used to emphasize and evaluate white matter fiber tracts. This method has been applied to MRI scans in diffusion weighted images. If full tensor data acquisition is applied, the fractional anisotropy (FA) is calculated from the eigenvalues

Fractional anisotropy. Fractional anisotropy is a scalar value between zero and one that describes the degree of anisotropy of a diffusion process. A value of zero means that diffusion is isotropic, i.e. it is unrestricted in all directions. A value of one means that diffusion occurs only along one axis and is fully restricted along all other. The fractional anisotropy (FA) gives information about the shape of the diffusion tensor at each voxel. The FA is based on the normalized variance of the eigenvalues . The fractional anisotropy reflects differences between an isotropic diffusion and a linear diffusion

What is Fractional Anisotropy 1. One of the commonly used measures of deviation from isotropy and reflects the degree of alignment of cellular structures within fiber tracts, as well as their structural integrity. Learn more in: Diffusion Tensor Imaging and Fiber Tractograph Furthermore, fractional anisotropy measurements on parahippocampal cingulum can potentially serve in evaluating the progression of neuronal deterioration (or even possible recovering) of AD. White matter (WM) fractional anisotropy (FA) is thought to be related to WM integrity and decline in FA is often used as an index of decreasing WM health. However, the relationship of FA to other structural indices of cerebral health has not been well studied Bilateral intersection of hippocampal cingulum and parahippocampal gyrus (referred as parahippocampal cingulum) is the region that best discriminates Alzheimer's disease fractional anisotropy values, resulting in an accuracy of 93% for discriminating between Alzheimer's disease and controls, and 90% between Alzheimer's disease and Mild Cognitive Impairment. These results suggest that pattern classification of Diffusion Tensor Imaging can help diagnosis of Alzheimer's disease, specially when. BACKGROUND AND PURPOSE: Fractional anisotropy (FA) is a useful measure of connectivity in the brain that can be derived from the diffusion tensor imaging (DTI) dataset

Fractional anisotropy in subcortical white matter of subjects with schizophrenia. Schizophrenia is reportedly associated with reduced FA in frontal regions, which correlates with cognitive and motor deficits in patients (Walther et al., 2011) Viele übersetzte Beispielsätze mit fractional anisotropy - Deutsch-Englisch Wörterbuch und Suchmaschine für Millionen von Deutsch-Übersetzungen. fractional anisotropy - Deutsch-Übersetzung - Linguee Wörterbuc Fractional anisotropy (FA) is a method that is used to emphasize and evaluate white matter fiber tracts. This method has been applied to MRI scans in diffusion weighted images. FA is a scalar value between 0 and 1 that describes the degree of anisotropy of a particular diffusion process. A value of 0 indicates that diffusion is isotropic, that is it is unrestricted or equally restricted in all. RESULTS: Fractional anisotropy and AD were increased in the three nigral subareas in PD (P < 0.01), but MD and RD were unaltered. The right SN had higher FA than the left in all subareas (P < 0.01). MD and AD were increased in the right anterior part (P < 0.04), whereas MD and RD were decreased in the right middle and posterior parts (P < 0.001)

We tested for an association between muscle power and standard DTI parameters, e. g. fractional anisotropy. MATERIALS AND METHODS: Maximal muscle power (Lmax) of the soleus muscle was determined in 11 healthy subjects. Subsequently DTI was performed and standard parameters (fractional anisotropy - FA, mean diffusivity - MD, parallel diffusivity - PD, radial diffusivity - RD) were extracted in an ROI of the soleus muscle. RESULTS: We found a signficant association of Lmax with FA (neg. INTERPRETATION: Significant changes in fractional anisotropy in individuals born preterm reflect white matter abnormalities from childhood to young adulthood, and the mechanism of fractional anisotropy alterations in preterm infants may vary during different stages of white matter development Reduced fractional anisotropy (FA) associated with Major Depressive Disorder (MDD) overlaps anatomically with effects of childhood maltreatment experiences. The aim of this study was, therefore, to replicate the negative effect of childhood maltreatment on white matter fiber structure and to demonstrate, that alterations in MDD might be partially attributed to the higher occurrence of.

The fractional anisotropy can also be separated into linear, planar, and spherical measures depending on the shape of the diffusion ellipsoid. [33] [34] For example, a cigar shaped prolate ellipsoid indicates a strongly linear anisotropy, a flying saucer or oblate spheroid represents diffusion in a plane, and a sphere is indicative of isotropic diffusion, equal in all directions. [35 Anisotropy (/ ˌ æ n. ə-, ˌ æ n. aɪ ˈ s ɒ t r. ə p. i /) is the property of a material which allows it to change or assume different properties in different directions as opposed to isotropy.It can be defined as a difference, when measured along different axes, in a material's physical or mechanical properties (absorbance, refractive index, conductivity, tensile strength, etc.

Cerebral tracts may be presented in 2D color images in: axial, coronal, and sagittal planes. The relational topographic appearance of the tracts are better identified in planes that are perpendicular to the major axis of the tract. For example, the corpus callosum which is an axial structure is better. Fractional anisotropy in the uncinate fasciculus differs significantly between patients with BD-I and patients with BD-II and healthy controls. This supports the hypothesis of differences in the physiological sub-tract between bipolar disorder subtypes. Similar results were found in unaffected siblings, suggesting the potential for this biomarker to represent an endophenotype for BD-I. However, fractional anisotropy in the uncinate fasciculus seems unrelated to polygenic risk for.

Main Cerebral Tracts on Orthogonal Fractional Anisotropy maps. Cerebral tracts may be presented in 2D color images in: axial, coronal, and sagittal planes. The relational topographic appearance of the tracts are better identified in planes that are perpendicular to the major axis of the tract. For example, the corpus callosum which is an axial structure is better defined in the sagittal or coronal view. Thus, tracts going anterior-posterior or posterior-anterior are better seen in coronal. Fractional Anisotropy is a normalized measure of the fraction of the tensor's magnitude due to anisotropic diffusion, corresponding to the degree of anisotropic diffusion or directionality and ranges from 0 (isotropic diffusion) to 1 (anisotropic diffusion).

Several studies (Reference Szeszko, Ardekani and Ashtari 7- Reference Benedetti, Giacosa and Radaelli 18) report either increased or decreased fractional anisotropy (FA) in OCD. FA is used to evaluate integrity of WM fibre tracts. Decreases in FA are interpreted as decreases in the WM integrity or increase in number of crossing fibres. Location and direction of the abnormal FA in OCD is inconsistent and the need for clarification of this issue is still prominent. One previous report. La anisotropía fraccionada (FA) es un valor escalar entre cero y uno que describe el grado de anisotropía de un proceso de difusión .

Therefore, we focused on fractional anisotropy (FA), which is used in neuroscience to evaluate anisotropic diffusion of water molecules in the body for revealing the shape of tiny nerve cells [11, 2]. In developing our method, we used FA to design a novel filter, which we call a fractional anisotropic filter, that passes only meaningful subtle changes and ig-nores non-meaningful ones. Our. This increase of fractional anisotropy occurred in the absence of demyelination: fluid leakage into the myelinated space increased the axial, but not the radial, diffusivity, resulting in the increased fractional anisotropy. This increased fractional anisotropy returned to pre-encephalopathy values in the recovery phase. Our results highlight the importance of the fractional anisotropy.
