This study investigates the link between cerebral perfusion and white matter injury in preterm infants. Cerebral perfusion images were acquired using a background suppressed pulsed continuous arterial spin labeling sequence, and white matter injury scores were derived from structural T1- and T2-weighted MRI using a standardized scoring system. The correlation between perfusion and white matter injury was assessed on a voxelwise basis by permutation testing. White matter injury scores were negatively correlated with perfusion in the cerebellum, basal ganglia, and thalamus, suggesting that perfusion may reflect a selective vulnerability to lesions in these areas and in the cerebral white matter.
