WebJul 1, 2024 · Cortical microstructural abnormalities are associated with clinical and cognitive deterioration in multiple sclerosis. Using diffusion tensor MRI, a higher fractional anisotropy has been found in cortical lesions versus normal-appearing cortex in multiple sclerosis. The pathological substrates of this finding have yet to be definitively elucidated. WebNov 11, 2024 · The aspiration group showed significantly increased fractional anisotropy and mode of anisotropy in the anterior limb and the genu of the internal capsule in the right hemisphere. In contrast, the normal group showed significantly increased mean diffusivity, mainly in the superior longitudinal fasciculus in the right hemisphere (P < 0.05 ...

WebThe aim of this study was to investigate fractional anisotropy (FA) in the WM of the whole brain in patients with OCD by using diffusion tensor imaging (DTI).Methods: In total, 28 unmedicated patients with OCD and 28 healthy volunteers underwent DTI scan. ... Li et al studied partly medicated OCD patients and reported significantly increased FA ... WebOct 10, 2012 · These findings indicate that myelination in wild-type animals increases fractional anisotropy by up to 20% and reduces radial diffusivity and mean diffusivity by ~13 and ~10%, respectively, compared to Shi mice . After transplantation of Shi animals with glial precursors, the fractional anisotropy increased by 8 to 15% in different voxels . diastolic blood pressure of 30

WebNov 2, 2015 · Increase in fractional anisotropy in cerebellum was the most prominent result. A decrease in fractional anisotrophy in patients comparable with previous studies was located in forceps minor. There were no differences in the white matter morphology or in the white matter hyperintensities between patients and healthy controls. WebNational Center for Biotechnology Information WebPrincipal Diffusion Direction Map This is a map that assigns colors to voxels based on a combination of anisotropy and direction. It is also called the colored fractional anisotropy map, fiber direction map or diffusion texture map.The color assignment is arbitrary, but the typical convention is to have the orientation of the principal eigenvector (ε1) control hue … citimanager for gtcc
