ABSTRACT Objective To measure pulmonary artery (PA) diameters and Doppler values in normal fetuses and to analyze their trends and correlations with gestational age (GA). Methods We took PA ultrasound measurements of normal fetuses with GAs of 20–32 weeks, including the main pulmonary artery (MPA),...
