Fetal Growth in Uterus Monitored by Ultrasound / 中国医学影像技术

ABSTRACT

Objective　To investigate the characteristics of fetal growth in uterus. Methods　A total of 695 term singleton infant were studied. Various ultrasound measurements (including Biparietal diameter BPD, Transverse abdomen-diameter AD, femur length FL) obtained from 26 weeks' gestation to term. 147 cases were macrosomia. 48 cases were intra-uterine growth retardation (IUGR). 500 cases were normal weight. We assessed the tendency of BPD/AD and AD/FL of fetal. Results　BPD/AD ratio of macrosomia was lowest, and BPD/AD ratio of IUGR was highest of them. The tendency of BPD/AD ratio were declined in gestation. AD/FL ratio of macrosomia were highest, and AD/FL ratio of IUGR was lowest of them. The tendency of AD/FL ratios were smooth in gestation. Conclusion　The tendency of fetal growth in uterus showed that the add of abdominal diameter contributed to gain in weight.
