Elastographic techniques are new ultrasound-based imaging techniques developed to estimate tissue deformability/stiffness. Several ultrasound elastographic approaches have been developed, such as static elastography, transient elastography and acoustic radiation force imaging methods, which include point shear wave and shear wave imaging elastography. The application of these methods in clinical practice aims at estimating the mechanical tissues properties. One of the main settings for the application of these tools has been liver stiffness assessment in chronic liver disease, which has been studied mainly using transient elastography. Another field of application for these techniques is the assessment of focal lesions, detected by ultrasound in organs such as pancreas, prostate, breast, thyroid, lymph nodes. Considering the frequency and importance of the detection of focal liver lesions through routine ultrasound, some studies have also aimed to assess the role that elestography can play in studying the stiffness of different types of liver lesions, in order to predict their nature and thus offer valuable non-invasive methods for the diagnosis of liver masses.
弹性成像技术是基于超声开发的新型成像技术，用于评估组织的可变形性/硬度。已经开发了几种超声弹性成像方法，如静态弹性成像、瞬时弹性成像和声辐射力成像方法，其中包括点剪切波弹性成像和剪切波弹性成像。这些方法在临床实践中的应用旨在评估组织的力学特性。这些工具的主要应用场景之一是慢性肝病中的肝脏硬度评估，主要使用瞬时弹性成像进行研究。这些技术的另一个应用领域是对在胰腺、前列腺、乳腺、甲状腺、淋巴结等器官中通过超声检测到的局灶性病变进行评估。考虑到通过常规超声检测局灶性肝病变的频率和重要性，一些研究还旨在评估弹性成像在研究不同类型肝病变硬度方面可以发挥多大作用，以便预测其性质，从而为肝肿块的诊断提供有价值的非侵入性方法。
