A total of 378 measurements of fetal liver size were made from 18 weeks gestation through term. Statistical analysis of the results showed a highly significant correlation between fetal liver measurements and gestational age, biparietal diameter, and fetal femur length (R = 0.93, R = 0.89, R = 0.89, respectively). Ultrasonic measurement of the fetal liver is a reliable indicator of fetal growth in the third trimester, as growth rates of the biparietal diameter and head circumference are blunt. Furthermore, consecutive measurements of fetal liver size enhance the detection of symmetrical, fetal growth, by acquisition of various ultrasonic parameters such as biparietal diameter, fetal femur length, fetal abdominal circumference and so forth.
从妊娠18周直至足月，共对胎儿肝脏大小进行了378次测量。结果的统计分析显示，胎儿肝脏测量值与孕周、双顶径及胎儿股骨长度之间存在高度显著的相关性（相关系数分别为R = 0.93、R = 0.89、R = 0.89）。超声测量胎儿肝脏是孕晚期胎儿生长的可靠指标，因为双顶径和头围的生长速率较平缓。此外，通过获取双顶径、胎儿股骨长度、胎儿腹围等各种超声参数，连续测量胎儿肝脏大小可提高对对称性胎儿生长的检测。
