A group of 252 patients who had total intrauterine volume (TIUV) measurements after 20 weeks menstrual age were evaluated for prediction of growth retardation. The measurements were compared to previously published normal values derived at out institution. The birth weights of these patients' babies were evaluated by the California standard. Setting the threshold of an abnormal test at the lower 10% tolerance limit, the TIUV measurement was sensitive in 70%, specific in 72%, and accurate in predicting IUGR in only 41% of cases. Ultrasonic estimation of TIUV is limited as a predictor of IUGR.
对一组252例月经龄20周后进行了子宫总容积（TIUV）测量的患者进行了生长迟缓预测评估。将测量结果与本机构先前公布的正常值进行了比较。这些患者所生婴儿的出生体重按照加利福尼亚标准进行评估。将异常检测的阈值设定在较低的10%耐受限度，TIUV测量在预测宫内生长受限（IUGR）方面的敏感性为70%，特异性为72%，准确性仅为41%。超声估计TIUV作为IUGR的预测指标存在局限性。
