Frey et al (2012) established a novel approach for fiber tracking based on navigated TMS mapping of the primary motor cortex and proposed a new algorithm for determination of an individualized fractional anisotropy value for reliable and objective fiber tracking.

DTI produces a measurement, called fractional anisotropy (FA), of the movement of water molecules along axons.

To measure white matter integrity, researchers used fractional anisotropy (FA), obtained by diffusion tensor imaging (DTI).

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).

Veterans who did not return to work displayed significantly lower fractional anisotropy (FA) and higher diffusivity in a specific brain region, the left internal capsule.

Effects of signal - to - noise ratio on the accuracy and reproducibility of diffusion tensor imaging - derived fractional anisotropy, mean diffusivity, and principal eigenvector measurements at 1.5 T.

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.

• Reduced white matter connectivity (as measured by reduced fractional anisotropy and increased radial diffusivity) for two discrete clusters on the forceps minor of the corpus callosum; and

The strongest predictions are the frontal pole grey matter volume and the posterior thalamic radiations, both such that greater volume and greater Fractional Anisotropy (FA) were associated with better scores.

LH GM metrics (i.e., percent spared cortical tissue) and bilateral WM scalars (i.e., fractional anisotropy [FA], mean diffusivity [MD]-RRB- were obtained from cortical and subcortical masks in each ROI.

A new approach for corticospinal tract reconstruction based on navigated transcranial stimulation and standardized fractional anisotropy values.

This imaging technique allows researchers to measure the uniformity of water movement (called fractional anisotropy, or FA) throughout the brain.

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

Just three of these significant differences — radial diffusivity in the right forceps minor, cortical thickness in the left pars opercularis and fractional anisotropy in the left forceps minor — yielded the best decision tree for distinguishing ASD participants from controls.

In particular, he employs two DTI measures — mean diffusivity and fractional anisotropy — to evaluate two fundamental elements of cartilage tissue — proteoglycan and collagen.
