We assessed micro and macrostructural cortical development in preterm infants using cortical curvature and thickness measures and neurite orientation and density imaging (NODDI). We studied two independent datasets of 64 and 42 neonates, and characterised the association between cortical features (median FA, MD, NDI, ODI, mean curvature and cortical thickness) and post-menstrual age (PMA) at MRI and gestational age at birth (degree of prematurity). We found a distinct pattern of development between the term (>37 weeks PMA) and preterm period (<37 weeks PMA), and different growth patterns between somatosensory and fronto-temporal areas.
