超声是评价腮腺病变的一线影像学检查;然而，单独超声不能区分良性和恶性病变。具有这种能力的成像技术将具有很大的价值，因为细针穿刺细胞学（FNAC）并不总是准确的，部分/全部腮腺切除术与面神经麻痹和弗雷综合征有关。超声弹性成像是一种新的成像技术，已用于研究环境中的组织，包括乳腺，甲状腺，前列腺和唾液腺的评价。最近，它已被用作诊断辅助超声评价大涎腺病变。这篇综述文章概述了超声弹性成像在腮腺病变诊断成像中的作用，特别是参考了两篇发表在《欧洲放射学》上的研究论文。这些文件采用略有不同的技术：第一个利用剪切波弹性成像，而第二个使用实时超声弹性成像。超声弹性成像可能作为常规超声的辅助诊断成像。然而，FNAC/芯活检似乎仍然是必要的。关键点超声是腮腺病变的初始且通常是决定性的研究已经尝试了基于超声的应变弹性成像，但提供的额外信息很少。新的剪切波弹性成像技术也没有带来太多的优势。然而，弹性成像模式的分析似乎比单独的超声提供了优势。
Ultrasound is the first-line imaging investigation in the evaluation of parotid gland lesions; however, ultrasound alone cannot differentiate between benign and malignant lesions. An imaging technique with this capability would be of great value, as fine needle aspiration cytology (FNAC) is not always accurate and partial/total parotidectomy is associated with facial nerve palsy and Frey's syndrome. Sonoelastography is a novel imaging technique that has been employed in the research setting in the evaluation of tissues including breast, thyroid, prostate and the salivary glands. More recently it has been used as a diagnostic adjunct in the sonographic evaluation of major salivary gland lesions. This review article outlines the current role of sonoelastography in the diagnostic imaging of parotid lesions, with particular reference to the findings of two research papers published in European Radiology. These papers employ slightly different techniques: the first utilises shear wave elastography whilst the second uses real-time sonoelastography. Sonoelastography may have potential as a diagnostic imaging adjunct to conventional ultrasound. However, it seems likely that FNAC/core biopsy will continue to be necessary. Further studies to evaluate the reproducibility of sonoelastographic results across a range of operators and systems are also needed.Key PointsUltrasound is the initial and often definitive investigation for parotid lesionsUltrasound-based strain elastography has been attempted but offered little additional informationNew shear wave elastographic techniques did not confer much advantage eitherHowever, analysis of elastographic patterns seems to provide advantages over ultrasound alone
