Colour-coded fractional anisotropy images: differential visualisation of white-matter tracts – preliminary experience
Diffusion-tensor analysis allows quantitative assessment of diffusion anisotropy. Fractional anisotropy (FA) is commonly used to quantify anisotropy. One of the limitations of FA imaging is, however, that it ...
