Infants with Congenital Heart Disease (CHD) are at increased risk of neurodevelopmental impairments. Forty-three neonates with CHD underwent multi-shell high angular resolution diffusion MRI (HARDI) on a 3T scanner before surgery. At 22 months parents completed a questionnaire characterising internalizing and externalizing behaviours. Network-based statistics were used to characterise the relationship between internalizing and externalizing symptoms and structural connectivity. Reduced neonatal structural connectivity in fronto-limbic regions before surgery was associated with increased externalizing symptomatology in toddlers with CHD.
