Elastography is a non-invasive imaging modality that has been developed for the evaluation of the stiffness of various organs. It is categorized into two main types: strain elastography and shear wave elastography. While strain elastography offers valuable information on the mechanical properties of the organ being studied, it is limited by the qualitative nature of its measurements and its reliance on operator skills. On the other hand, shear wave elastography overcomes these limitations as it provides a quantitative assessment of tissue stiffness, offers more reproducibility, and is less operator-dependent. Endoscopic ultrasound-guided shear wave elastography (EUS-SWE) is an emerging technique that overcomes the limitations of transabdominal ultrasound in the evaluation of the pancreas. A growing body of literature has demonstrated its safety and feasibility in the evaluation of pancreatic parenchyma. This article provides a comprehensive review of the current state of the literature on EUS-SWE, including its technical aspects, clinical applications in the evaluation of various pancreatic conditions, technological limitations, and future directions.
弹性成像术是一种已被开发用于评估各种器官硬度的非侵入性成像方式。它主要分为两种类型：应变弹性成像和剪切波弹性成像。虽然应变弹性成像能提供有关所研究器官力学特性的有价值信息，但它受测量的定性性质及其对操作者技能的依赖所限。另一方面，剪切波弹性成像克服了这些局限性，因为它能对组织硬度进行定量评估，具有更高的可重复性，且对操作者的依赖性较小。内镜超声引导下剪切波弹性成像（EUS-SWE）是一种新兴技术，它克服了经腹超声在胰腺评估中的局限性。越来越多的文献已证明其在评估胰腺实质方面的安全性和可行性。本文全面综述了关于EUS-SWE的文献现状，包括其技术方面、在评估各种胰腺疾病中的临床应用、技术局限性以及未来发展方向。
