Abstract/OtherAbstract:
Abstract Objective: Documentation of examination of brain structural development by MRI beyond the neonatal period is scarce for both preterm and small for gestational age (SGA) infants. Aim: To investigate by MRI structural brain development during infancy in preterm children born SGA. Methods: A total of 205 preterm infants, 139 appropriate for GA (AGA) and 66 SGA, of which 33 had birth weight (BW)<3(rd) percentile and 33 had BW 3(rd)-10(th) percentile, were examined prospectively by brain MRI at the corrected age of 5 months. The total volume of the brain, ventricles and cerebellum, the area of vermis and corpus callosum, and the height of the pituitary, mesencephalon and pons were estimated on MRI. Results: Brain volume was smaller in the SGA<3(rd) percentile infants, independent of other perinatal factors. Chronic lung disease was an independent predictor of low brain volume. Pituitary height was greater in SGA<3(rd) percentile than in AGA infants. The corpus callosum area was less in SGA<3(rd) percentile than in SGA 3(rd)-10(th) percentile infants. Conclusions: Preterm infants born SGA with BW<3(rd) percentile had differences in brain structural measurements at the corrected age of 5 months, compared with preterm AGA infants, which could have implications for their neurocognitive development.
