PURPOSE
Early detection of fetal sex is becoming more popular. The aim of this study was to evaluate the accuracy of fetal sex determination in the first trimester, using 3D virtual reality.
METHODS
Three-dimensional (3D) US volumes were obtained in 112 pregnancies between 9 and 13 weeks of gestational age. They were offline projected as a hologram in the BARCO I-Space and subsequently the genital tubercle angle was measured. Separately, the 3D US aspect of the genitalia was examined for having a male or female appearance.
RESULTS
Although a significant difference in genital tubercle angles was found between male and female fetuses, it did not result in a reliable prediction of fetal gender. Correct sex prediction based on first trimester genital appearance was at best 56%.
CONCLUSION
Our results indicate that accurate determination of the fetal sex in the first trimester of pregnancy is not possible, even using an advanced 3D US technique.
目的
胎儿性别的早期检测越来越普遍。本研究的目的是评估使用三维虚拟现实技术在孕早期确定胎儿性别的准确性。
方法
对112例孕龄在9至13周之间的孕妇进行了三维超声检查。将这些三维超声图像在BARCO I-Space中离线投影为全息图，随后测量生殖结节角。另外，检查生殖器的三维超声外观，判断其呈现男性或女性特征。
结果
虽然发现男性和女性胎儿的生殖结节角存在显著差异，但这并未导致对胎儿性别的可靠预测。基于孕早期生殖器外观的正确性别预测率最高为56%。
结论
我们的结果表明，即使使用先进的三维超声技术，在妊娠早期准确确定胎儿性别也是不可能的。
