Sentences with phrase «with fractional anisotropy»

The scientists found that maternal iron intake correlated inversely with fractional anisotropy (FA)-- a unit of measurement in DTI that is a useful measurement of tissue organization in the brain — at locations scattered throughout the gray matter of the brain.

Not exact matches

Compared to controls, patients with depression had decreased fractional anisotropy (FA), a measure of the structural integrity of white matter connections, around an area near the deep gray matter of the brain that is strongly associated with the brain's reward circuit.

Comparing MRI brain images of eight Dobermans with CCD to the control group, Ogata found that the CCD group had higher total brain and gray matter volumes, lower gray matter densities in the dorsal anterior cingulate cortex and right anterior insula, and higher fractional anisotropy in the splenium of the corpus callosum (the degree of which correlated with the severity of the behavioral traits).

Among other white matter tracts, the white matter organization of the cingulum tract (as reflected by the level of fractional anisotropy measured with diffusion tensor imaging) was found to be positively associated with IQ.

Blue indicates regions of the brain in which lower fractional anisotropy (a measure of microstructural integrity) correlated with more severe neurobehavioral symptoms.

Wolff and colleagues report that infants with ASD showed higher fractional anisotropy (FA) of most fiber tracts at 6 months followed by a slower change over time relative to infants without ASD such that by 24 months of age, the infants with ASD had lower FA values (Wolff et al., 2012).

Diffusion Tensor Imaging (DTI) and fractional anisotropy (FA) have enabled neuroradiologist and neurologists the ability to identify and quantify abnormal patterns within the brain that when paired with a history of trauma, can help to establish the existence of a brain injury.

In line with evidence in AB [151] significant differences in the fractional anisotropy (FA) measures of the uncinate fasciculus have been demonstrated in adolescents with conduct disorder [29,39] as well as in adult psychopathy [144,152].

The figure depicts increased fractional anisotropy in adolescents with Conduct Disorder with elevated callous - unemotional traits (CD / CU +) relative to those with Conduct Disorder with lower levels of callous unemotional traits (CD / CU --RRB-.

However, relatively few studies have investigated whether there are differences in brain structure between these subgroups.We acquired diffusion tensor imaging data and used tract - based spatial statistics (TBSS) to compare adolescents with CD and high levels of CU traits (CD / CU +; n = 18, CD and low levels of CU traits (CD / CU -; n = 17) and healthy controls (HC; n = 32) on measures of fractional anisotropy (FA), axial (AD), radial (RD) and mean (MD) diffusivity.
