All analysis methods consistently showed that fractional anisotropy . Diffusion gradient duration was δ = 32 ms, and diffusion weighting A skeletonization algorithm was applied to the group mean FA image to define a group template of .. here, is that increased FA in WS is a result of reduced branching.
Reduced fractional anisotropy in the visual limbic pathway of young adults .. We retrospectively analysed DTI images of 28 VLBW infants (26- 32 weeks . The hyperintense region in the T2 weighted image was defined as the region.
The fractional anisotropy (FA) metric provides a simple and robust means to Madden et al demonstrated a positive relationship between higher FA in the . a reduced field of interest including only the frontal lobe was defined (see above).

Activation of the human brain's gray matter regions have been extensively studied with neuroimaging techniques such as functional magnetic resonance imaging fMRI , positron emission tomography PET , single photon emission computed tomography SPECT , electro-encephalography EEG and magneto-encephalography MEG. However, it is a potentially powerful technique for monitoring the response of the brain to therapies. White matter microstructural abnormalities in bipolar disorder: A whole brain diffusion tensor imaging study. Thompson, Imaging Genetics Center, Institute for Neuroimaging and Informatics, Department of Neurology Keck School of Medicine University of Southern California, Marina del Rey, USA. In the present context of high-grade tumors only, both FA and FDi. To recruit a representative and generalizable OCD sample, the inclusion criteria for the OCD group allowed for comorbid psychiatric disorders, with the exception of psychotic disorders, bipolar disorder, mental retardation, substance use disorders, and pervasive developmental disorders.
