Ultrasound estimation of fetal weight or ultrasound measurement of fetal abdomen alone enables identification of small-for-gestational-age fetuses. A prerequisite for this is a reliable dating of pregnancy, which is provided by a routine ultrasound screening in the first half of gestation. The fetal growth can be followed by serial fetometric measurements. As a standard, charts of intrauterine growth based on the ultrasonic measurement can be used. As a secondary diagnostic test for monitoring fetal health in pregnancies suspected of intrauterine growth retardation, Doppler ultrasound evaluation of fetal and uteroplacental hemodynamics provided useful for early detection of imminent fetal distress.
超声估计胎儿体重或仅超声测量胎儿腹部就能识别小于孕周的胎儿。前提是要有可靠的孕周确定，这可通过妊娠前半期的常规超声筛查来实现。通过连续的胎儿测量可跟踪胎儿生长情况。作为标准，可使用基于超声测量的子宫内生长图表。作为监测疑似子宫内生长受限妊娠中胎儿健康的二级诊断测试，对胎儿和子宫胎盘血流动力学的多普勒超声评估有助于早期发现即将发生的胎儿窘迫。
