Normal and Hypoplastic Fetal Lungs: Volumetric Assessment with Prenatal Single-Shot Rapid Acquisition with Relaxation Enhancement MR Imaging

Abstract

Normal fetal total lung volume is strongly correlated with biometric measurements. Relative fetal lung volume can be calculated by expressing the observed volume as a percentage of the predicted volume calculated from biometric measurements; knowledge of the relative fetal lung volume assists in the confirmation and quantification of fetal pulmonary hypoplasia.
