The Role of Magnetic Resonance Imaging in Fetal Lung Maturation

The assurance of fetal lung maturation is important in preterm birth. Pulmonary maturity does affect postnatal respiratory function and is associated with significant neonatal morbidity and mortality. This study aimed at assessing the role of magnetic resonance imaging evaluation of fetal lung maturation correlated with the respiratory status of the neonates. 1.In fetuses with normal chest, FLV increased as pregnancy advanced as well as Signal intensity and lung to liver signal intensity ratio. 2.In high risk fetuses , FLV, SI and lung to liver signal intensity ratios increased significantly with the progress of pregnancy. 3.FLV was lower among high risk fetuses than control fetuses. 4.fetuses with poor respiratoy outcome had significantly smaller FLV. 5.The mean FLV and SI increase after antenatal corticosteroids therapy.
