Abstract

We sought to establish normative data for fetal liver volume (FLV) between 27 and 38 weeks' gestation using three-dimensional ultrasonography. The study design was a longitudinal prospective study involving 53 participants. A total of 250 FLV measurements were obtained, using the multiplanar method with 3.0-mm intervals. Polynomial regressions with adjustments using the determination coefficient ( R2) were used to assess the correlation between FLV and gestational age (GA) and fetal parameters (biparietal diameter, head circumference, abdominal circumference, and estimated fetal weight). The mean, standard deviation, and median, minimum, and maximum values were calculated for each gestational age. The intraclass correlation coefficient (ICC) was used to determine inter- and intraobserver reliability. There was a high correlation between FLV and GA. The mean FLV went from 43.5 +/- 7.6 cm (3) (29.1 to 62.2 cm (3)) to 130.5 +/- 20.1 cm3 (87.5 to 191.1 cm3). There was a high correlation between FLV and all fetal biometric parameters (all P < 0.0001). Intraobserver and interobserver correlations were excellent with an ICC = 0.993 and 0.984, respectively. There was a high correlation between GA and biometric parameters. Reference limits were generated for FLV between 27 and 38 weeks. FLV is highly reproducible.

摘要

我们旨在使用三维超声技术为 27 至 38 孕周胎儿肝体积(FLV)建立规范数据。该研究设计为一项涉及 53 名参与者的前瞻性纵向研究。使用多平面法以 3.0mm 的间隔获得了总共 250 次 FLV 测量值。使用调整后的决定系数(R2)进行多项式回归,以评估 FLV 与胎龄(GA)和胎儿参数(双顶径、头围、腹围和估计胎儿体重)之间的相关性。计算了每个胎龄的平均值、标准差、中位数、最小值和最大值。使用组内相关系数(ICC)来确定观察者内和观察者间的可靠性。FLV 与 GA 之间存在高度相关性。FLV 的平均值从 43.5 +/- 7.6 cm(3)(29.1 至 62.2 cm(3))变为 130.5 +/- 20.1 cm3(87.5 至 191.1 cm3)。FLV 与所有胎儿生物测量参数之间存在高度相关性(均 P < 0.0001)。观察者内和观察者间的相关性均极好,ICC 分别为 0.993 和 0.984。GA 和生物测量参数之间存在高度相关性。在 27 至 38 孕周之间生成了 FLV 的参考限值。FLV 具有高度可重复性。
