Introduction: Visual impairment in preterm infants at term equivalent age (TEA) is associated with impaired microstructural development in the optic radiation, measured as reduced fractional anisotropy (FA) by Diffusion Tensor Imaging (DTI). We tested the hypothesis that these abnormalities develop during the late preterm period. Methods: DTI...

Our aim was to compare white matter (WM) microstructure in preterm infants with and without punctate WM lesions on MRI using tract-based spatial statistics (TBSS) and probabilistic tractography. We studied 23 preterm infants with punctate lesions, median GA at birth 30 (25-35) wk, and 23 GA- and sex-matched preterm controls. TBSS and...
