Considering
the extra-environmental associated effects on brain development, it may be unreasonable
to scan preterm infants at term-equivalent GA. To clarify this, we aim to explore
the effects of postnatal days on neonatal WM maturation by DTI. Results
indicate that postnatal days at-scan may be a considerable factor to
investigate the WM maturation: during a close to in-uterine period, the absent
effects of postnatal days may suggest the reasonability of performing neonatal
MR-scans in such period; while as postnatal days increases, observed FA changes
may imply the bias of comparing the preterm neonates at term-equivalent GA to
term ones.
