Neonatal brain is highly vulnerable to injury resulting in subsequent cognitive and motor disabilities. Our goal was to show that there are microstructural abnormalities in regions of the brain separate from the focal necroses in non-cystic periventricular leukomalacia. A diverse cohort of neonates was scanned at term equivalent age using DTI. We found that there is microstructural injury in white matter regions both proximal and distant from necrotic foci.
