Shown are axial MRIs of children with, left to right, holoprosencephaly (brain malformation), schizencephaly (brain malformation), periventricular leukomalacia (prematurity), and hypoxic-ischemic encephalopathy (neonatal encephalopathy).
Axial diffusion tensor images of the same children as above, in the same order as above, reveal white matter tracts oriented in the plane of the image (shown in blue), up and down (shown in green), and left to right (shown in red). Photos courtesy Dr. Susumu Mori and Dr. Lidia Nagae-Poetscher
