Synopsis

Adequate placental structure and function are crucial for fetal and maternal health. Here we assessed late-gestation placental perfusion (N=50, GA=31-38 weeks) using pseudocontinuous arterial-spin-labeling and radiomics feature-extraction, and their association with umbilical-cord insertion-site and the risk of fetal-growth-restriction (FGR). Increased blood-flow and arterial-transit-time were detected in our normal cases compared to earlier gestation as reported previously. Perfusion features differences were detected in placentas with marginal compared to central cord-insertion, indicating higher intensity heterogeneity. No differences were found between normal and FGR placentas. This study provides normal late-gestation placental perfusion values based on a large cohort, and implies on structural-functional associations.
