Ultrasound is key to evaluating placental function. However, traditional ultrasound examinations cannot evaluate the changes in the biomechanical properties of the placenta in vivo. As a non-invasive technique, shear wave elastography (SWE) can be used analyze the physiological and biomechanical properties of the placenta. Moreover, it can evaluate the pathological changes in early placental insufficiency in a more direct and sensitive manner. This study aimed to systematically introduce SWE in placental function evaluations. The terms 'placenta', 'ultrasound', and 'elastography' were searched on Pubmed, Embase, and CNKI databases (Apr 2023); this review was limited to results including placental sonoelastography. Twenty-six studies satisfied the inclusion criteria and were included in this review. Herein, we introduce the basic principle of SWE, analyze the factors affecting placental measurements, and summarize the prospects of clinical applications of SWE in the field of obstetrical diseases. The SWE technology demonstrates excellent clinical application value and research prospects in obstetrics, particularly in placental function evaluation, owing to its objective and repeatable quantitative operation.
超声检查是评估胎盘功能的关键。然而，传统的超声检查无法评估胎盘在体内的生物力学特性变化。作为一种非侵入性技术，剪切波弹性成像（SWE）可用于分析胎盘的生理和生物力学特性。此外，它还可以更直接、更敏感地评估早期胎盘功能不全的病理变化。本研究旨在系统介绍 SWE 在胎盘功能评估中的应用。在 Pubmed、Embase 和中国知网（CNKI）数据库中以“胎盘”“超声”和“弹性成像”为检索词进行检索（2023 年 4 月）；本综述仅限于包括胎盘声触诊弹性成像结果的研究。26 项研究符合纳入标准，并被纳入本综述。本文介绍了 SWE 的基本原理，分析了影响胎盘测量的因素，并总结了 SWE 在妇产科疾病领域的临床应用前景。SWE 技术在妇产科领域具有出色的临床应用价值和研究前景，尤其在胎盘功能评估方面，因为它具有客观和可重复的定量操作。
