Breast elastography is a new sonographic imaging technique which provides information on breast lesions in addition to conventional ultrasonography (US) and mammography. Elastography provides a noninvasive evaluation of the stiffness of a lesion. Today, two technical solutions are available for clinical use: strain elastography and shear wave elastography. Initial evaluations of these techniques in clinical trials suggest that they may substantially improve the possibility of differentiating benign from malignant breast lesions thereby limiting recourse to biopsy and considerably reducing the number of benign breast biopsy diagnoses. This article reviews the basics of this technique, how to perform the examination, image interpretation and the results of major clinical studies. Although elastography is easy to perform, training and technical knowledge are required in order to obtain images permitting a correct interpretation. This paper will highlight the technique and point out common pitfalls.

乳腺弹性成像术是一种新的超声成像技术，除了传统超声检查（US）和乳腺X线摄影外，它还能提供有关乳腺病变的信息。弹性成像术可对病变的硬度进行无创评估。如今，有两种技术方案可供临床使用：应变弹性成像和剪切波弹性成像。这些技术在临床试验中的初步评估表明，它们可能会大幅提高鉴别乳腺良恶性病变的可能性，从而减少活检的必要性，并显著减少乳腺良性活检诊断的数量。本文回顾了该技术的基础知识、检查方法、图像解读以及主要临床研究结果。尽管弹性成像术操作简便，但为了获得能够正确解读的图像，仍需要进行培训并具备专业技术知识。本文将重点介绍该技术并指出常见的陷阱。乳腺弹性成像术是一种新的超声成像技术，除了传统超声检查（US）和乳腺X线摄影外，它还能提供有关乳腺病变的信息。弹性成像术可对病变的硬度进行无创评估。如今，有两种技术方案可供临床使用：应变弹性成像和剪切波弹性成像。这些技术在临床试验中的初步评估表明，它们可能会大幅提高鉴别乳腺良恶性病变的可能性，从而减少活检的必要性，并显著减少乳腺良性活检诊断的数量。本文回顾了该技术的基础知识、检查方法、图像解读以及主要临床研究结果。尽管弹性成像术操作简便，但为了获得能够正确解读的图像，仍需要进行培训并具备专业技术知识。本文将重点介绍该技术并指出常见的陷阱。
