Fetal central nervous system malformations are among the most common congenital anomalies. Whereas simple axial views are sufficient for basic fetal brain examination, other important views are essential for a more detailed examination, which are sometimes challenging to obtain. Three-dimensional ultrasound can be helpful in obtaining standardized and reproducible images of many difficult fetal brain views. The aim of the present review is to explore the most recent evidence on the utility and technique of three-dimensional ultrasound in the examination of the fetal brain, with particular emphasis on the brain views that benefit from three-dimensional ultrasound.
The article describes the various techniques of acquisition and analyses of three-dimensional ultrasound volumes of the fetal brain and their usefulness in the assessment of normal and abnormal fetal brain anatomy. Three-dimensional ultrasound has also permitted the application of many new technologies, such as artificial intelligence and deep machine learning. Recently, thanks to high-quality three-dimensional ultrasound, fetal cortical development can be assessed quantitatively and reliably.
Three dimensional ultrasound can help as a complementary tool to two-dimensional ultrasound in the assessment of the fetal brain development and malformations. In addition, it paves the way for the application of promising technologies in the evaluation of fetal brain.
A video summarizing the findings of the article. The video illustrates the various approaches and techniques applied for the examination of the fetal brain using three-dimensional ultrasound. Furthermore, the advantages and future perspectives of the application of three-dimensional ultrasound in the examination of the fetal brain are discussed, http://links.lww.com/COOG/A74.
胎儿中枢神经系统畸形是最常见的先天性畸形之一。虽然简单的轴向视图足以进行基本的胎儿大脑检查，但其他重要的视图对于更详细的检查是必不可少的，而这些视图有时很难获得。三维超声有助于获得许多困难的胎儿大脑视图的标准化和可重复的图像。本综述的目的是探讨三维超声在胎儿大脑检查中的最新应用证据和技术，特别强调受益于三维超声的大脑视图。
本文描述了获取和分析胎儿大脑三维超声体积的各种技术及其在评估正常和异常胎儿大脑解剖结构中的作用。三维超声还允许应用许多新技术，如人工智能和深度学习。最近，由于高质量的三维超声，可以对胎儿皮质发育进行定量和可靠的评估。
三维超声可以作为二维超声评估胎儿大脑发育和畸形的辅助工具。此外，它为评估胎儿大脑的有前途的技术的应用铺平了道路。
总结本文发现的视频。该视频说明了使用三维超声检查胎儿大脑的各种方法和技术。此外，还讨论了三维超声在胎儿大脑检查中的应用的优势和未来展望。http://links.lww.com/COOG/A74。
