title: Ultrasound placental study and fetal lung maturity.
abstract: This study was undertaken to ascertain the usefulness of placental development ultrasound study in prediction of RDS. We examined 96 women near term of pregnancy; the accuracy of placental maturity grades in predicting fetal lung maturity was compared with lecithin/sphingomyelin ratio and with clinical development of RDS in the infants. We observed good correlation among ultrasound placental grades and fetal maturity.
