fractional anisotropy biomarker_for white matter

Fractional anisotropy was used as our measure of tract integrity, given that earlier studies have indicated it to be a reliable assessment of microstructural integrity of white matter fibers.

white matter fiber integrity is commonly measured in terms of fractional anisotropy (FA), which is usually higher in fibers ... such as healthy white matter

Developmental studies of white matter coherence have demonstrated increasing FA across adolescence
