Intrauterine growth retardation (IUGR) may arise from a variety of causes, including placental insufficiency, maternal diseases, and fetal anomalies. Sonography plays a number of important roles in the diagnosis and management of growth retardation. Diagnosis of IUGR is based on fetal measurements, assessment of amniotic fluid volume, and other sonographic findings. Once IUGR has been diagnosed, sonography can help establish its cause. If a lethal cause is excluded, the fetus is monitored for the remainder of the pregnancy using sonography, including serial fetal measurements, biophysical profiles, and Doppler waveform indexes. Used appropriately, sonography can improve the outcome of fetuses with IUGR.
胎儿宫内生长受限（IUGR）可能由多种原因引起，包括胎盘功能不全、母体疾病和胎儿畸形。超声检查在生长受限的诊断和管理中发挥着重要作用。IUGR的诊断基于胎儿测量、羊水量评估及其他超声检查结果。一旦诊断出IUGR，超声检查有助于确定其病因。如果排除了致命原因，在妊娠剩余时间内使用超声检查对胎儿进行监测，包括连续胎儿测量、生物物理评分和多普勒波形指数。合理使用超声检查可改善IUGR胎儿的结局。
