Sonography has been the fundamental pillar of fetal diagnosis, and until relatively recently, no other valid and reliable noninvasive technique that could adequately determine fetal morphology was available. However, even after the technological advances in obstetric sonography, is still unable to detect some anomalies. One example of this shortcoming is the morphological study of the face and neck. Owing to the ossification of adjacent structures and interposition of the tongue, sonography is not accurate in the detection of some of the most common anomalies. Enormous advances have been made in fetal magnet resonance imaging since it was first described 25 years ago. The usefulness of this modality as a tool to complement sonography in fetal evaluation is now firmly established. MRI provides useful information about orofacial anatomy, enabling accurate evaluation of both the primary and secondary palates.
超声检查一直是胎儿诊断的基本支柱，直到最近，还没有其他有效且可靠的非侵入性技术能够充分确定胎儿形态。然而，即使产科超声技术取得了进展，它仍然无法检测到一些异常情况。这种缺点的一个例子是面部和颈部的形态学研究。由于相邻结构的骨化和舌头的阻挡，超声检查在检测一些最常见的异常情况时并不准确。自25年前首次被描述以来，胎儿磁共振成像（MRI）已经取得了巨大进展。这种检查方式作为在胎儿评估中补充超声检查的工具，其有用性现已得到明确确立。MRI提供了有关口面部解剖结构的有用信息，能够准确评估原发腭和继发腭。
