Breast elastography is a new sonographic imaging technique for the characterization of focal breast lesions in addition to conventional ultrasonography (US) and mammography. Elastography provides a non-invasive evaluation of the stiffness of a lesion. Two different technical approaches are available for clinical use: free-hand elastography (USE) and shear wave elastography (SWE). Initial results of these techniques in clinical trials suggest that elastography substantially improves the US capability in differentiating benign from malignant breast lesions, thus reducing the number of breast biopsies in benign nodules. This review paper, based on an extensive literature search, highlights the basics of breast elastography, including main technical features, how to do suggestions, limit and pitfalls, and presents the results of major clinical studies.
乳腺弹性成像是一种新的超声成像技术，除了常规超声（US）和乳房 X 线摄影术外，还可用于局灶性乳腺病变的特征描述。弹性成像是对病变硬度的一种非侵入性评估。有两种不同的技术方法可用于临床应用：手持弹性成像（USE）和剪切波弹性成像（SWE）。这些技术在临床试验中的初步结果表明，弹性成像可显著提高 US 区分良性和恶性乳腺病变的能力，从而减少良性结节中乳腺活检的数量。本综述论文基于广泛的文献检索，重点介绍了乳腺弹性成像的基础知识，包括主要技术特点、操作建议、局限性和缺陷，并呈现了主要临床研究的结果。
