Abstract
【Abstract】 Objective To build a nomogram normal fetal abdominal longitudinal diameter ratio, total lung area and lungs horizontal diameter throughout gestational age estimated by two-dimensional ultrasonography. Through these data to assess the value of lung development. Methods Two-dimensional ultrasonography was used to examine 592 normal singleton pregnancies at 18-40 weeks gestation. measured the heart horizontal tangen
