Tissue stiffness has long been known to be a biomarker of tissue pathology. Ultrasound elastography measures tissue mechanical properties by monitoring the response of tissue to acoustic energy. Different elastographic techniques have been applied to many different tissues and diseases. Depending on the pathology, patient-based factors, and ultrasound operator-based factors, these techniques vary in accuracy and reliability. In this review, we discuss the physical principles of ultrasound elastography, discuss differences between different ultrasound elastographic techniques, and review the advantages and disadvantages of these techniques in clinical practice.
组织硬度一直以来都被认为是组织病理学的生物标志物。超声弹性成像是通过监测组织对声能的响应来测量组织的力学特性。不同的弹性成像技术已经应用于许多不同的组织和疾病。根据病理学、基于患者的因素和基于超声操作者的因素，这些技术在准确性和可靠性上有所不同。在这篇综述中，我们讨论了超声弹性成像的物理原理，讨论了不同超声弹性成像技术之间的差异，并回顾了这些技术在临床实践中的优缺点。
