Fast quantitative diffusion-tensor imaging of cerebral white matter from the neonatal period to adolescence

JFL Schneider, KA Il'Yasov, J Hennig, E Martin - Neuroradiology, 2004 - Springer
We investigated the isotropic diffusion coefficient (D’) and fractional anisotropy (FA) in white
matter (WM) during brain development, using an optimised diffusion-tensor imaging (DTI) …
