自古以来，人工触诊就是软组织状态的信息来源，能够检测出伴随着组织弹性变化的各种疾病。在过去的二十年里，由于许多新兴的弹性成像(EI)方法，古老的触诊艺术获得了新的生命。EI在医疗诊断和治疗监测中的应用领域正在稳步扩大。弹性成像方法正在作为商业应用出现，这是该领域进步和重要性的真实证明。本文简要介绍了EI的历史和理论基础，描述了EI的各种技术，分析了它们的优点和局限性，并概述了EI的主要临床应用。根据在组织中产生应力的方法(外部机械力、内部超声辐射力或内部内生力)以及组织响应的测量，我们提出了弹性测量和成像技术的分类。该测量方法可以使用不同的物理原理来执行，包括磁共振成像(MRI)、超声成像、X射线成像、光学和声学信号。直到最近，EI在很大程度上是少数拥有进行研究所需特殊设备的选定机构使用的研究方法。然而，自2005年以来，越来越多的主流制造商将EI添加到他们的超声系统中，以至于今天大多数制造商都在他们的临床系统上提供某种类型的弹性成像或组织硬度成像。现在可以肯定地说，几乎所有类型的局灶性和弥漫性疾病都可以进行某种弹性成像。大多数新的应用仍处于早期研究阶段，但少数正在成为临床实践中的常见应用。
From times immemorial manual palpation served as a source of information on the state of soft tissues and allowed detection of various diseases accompanied by changes in tissue elasticity. During the last two decades, the ancient art of palpation gained new life due to numerous emerging elasticity imaging (EI) methods. Areas of applications of EI in medical diagnostics and treatment monitoring are steadily expanding. Elasticity imaging methods are emerging as commercial applications, a true testament to the progress and importance of the field. In this paper we present a brief history and theoretical basis of EI, describe various techniques of EI and, analyze their advantages and limitations, and overview main clinical applications. We present a classification of elasticity measurement and imaging techniques based on the methods used for generating a stress in the tissue (external mechanical force, internal ultrasound radiation force, or an internal endogenous force), and measurement of the tissue response. The measurement method can be performed using differing physical principles including magnetic resonance imaging (MRI), ultrasound imaging, X-ray imaging, optical and acoustic signals. Until recently, EI was largely a research method used by a few select institutions having the special equipment needed to perform the studies. Since 2005 however, increasing numbers of mainstream manufacturers have added EI to their ultrasound systems so that today the majority of manufacturers offer some sort of Elastography or tissue stiffness imaging on their clinical systems. Now it is safe to say that some sort of elasticity imaging may be performed on virtually all types of focal and diffuse disease. Most of the new applications are still in the early stages of research, but a few are becoming common applications in clinical practice.
