Several technological advances have greatly improved three-dimensional sonography, which have improved acquisition and display capabilities. This review describes these technical changes as well as current applications of 3D sonography in prenatal diagnosis.
Recently published papers have emphasized the potential of getting a precise 'any plane of choice' from a three-dimensional volume, as a new way of scanning, based on the off-line analysis of a volume dataset. Surface mode has been used to demonstrate malformations and genetic diseases. The maximum rendering mode, which highlights bones, has great potential for imaging the nasal bones and the frontal bones with the metopic suture. Organ volume can be measured, but the utility of this in clinical practice remains to be determined. Three-dimensional ultrasound needs to be standardized.
Three-dimensional ultrasonography is the most rapidly developing technique in fetal imaging. New features will permit the transition from the era of 'sonography in two-dimensional planes' to 'volume ultrasound'.
多项技术进步极大地改进了三维超声检查，提升了采集和显示能力。本综述描述了这些技术变革以及三维超声在产前诊断中的当前应用。
最近发表的论文强调了基于容积数据集的离线分析，从三维容积中获取精确“任意选择平面”作为一种新扫描方式的潜力。表面模式已用于显示畸形和遗传疾病。突出骨骼的最大渲染模式在成像鼻骨和有额缝的额骨方面具有很大潜力。可以测量器官容积，但在临床实践中的效用仍有待确定。三维超声需要标准化。
三维超声检查是胎儿成像中发展最迅速的技术。新特性将使从“二维平面超声检查”时代向“容积超声”时代转变成为可能。
