This study was done to produce enhanced fetal biometry charts and graphs presenting percentile values as a function of fetal age.
The relationships between the ultrasound measurements of 10 fetal parameters and menstrual age were determined by a cross-sectional study. Data were obtained from 508 to 790 fetuses. Anatomic structures were scanned and measured 3 times during 1 routine sonographic examination. The study group consisted of 1,396 Caucasian women who had normal singleton fetuses with confirmation of menstrual dates by sonography before 14 weeks and for whom complete pregnancy outcome information was available. For each of the 10 parameters, percentile curves were derived for the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles.
Ready-to-use fetal measurement charts and graphs are presented in a format giving the percentile values as a function of fetal age. There were no significant differences between male and female fetuses.
These fetal biometry charts and graphs, obtained from a North American Caucasian population, enhance previously published data.
本研究旨在制作增强型胎儿生物测量图表和曲线图，展示百分位数作为胎儿年龄的函数。
通过横断面研究确定10项胎儿参数的超声测量值与月经年龄之间的关系。数据来自508至790例胎儿。在1次常规超声检查期间对解剖结构进行3次扫描和测量。研究组由1396名白人女性组成，她们怀有正常单胎胎儿，在14周前通过超声检查确认了月经日期，且可获得完整的妊娠结局信息。对于10项参数中的每一项，得出了第5、10、25、50、75、90和95百分位数的百分位数曲线。
以一种将百分位数作为胎儿年龄函数的格式呈现了现成可用的胎儿测量图表和曲线图。男胎和女胎之间无显著差异。
这些从北美白人人群获得的胎儿生物测量图表和曲线图完善了先前发表的数据。
