Sarcopenia is age-related progressive and generalized loss of skeletal muscle mass and strength. Its prevalence is rising, which poses a burden for society because it increases disability and dependency and therefore raises health care costs. Muscle mass quality, however-an essential part of sarcopenia-is not easily diagnosable yet. Recent interest has risen for ultrasonographic evaluation of muscle. This review introduces muscle elastography as a possible, easy and cheap tool to evaluate qualitative muscle parameters. Basic principles of muscle elastography are described, as well as different elastography techniques and some technical considerations. Furthermore, a proposal for practical guidelines is offered and factors influencing muscle stiffness are highlighted.
肌肉减少症是一种与年龄相关的进行性和全身性骨骼肌质量和力量丧失。其患病率正在上升，这给社会带来了负担，因为它增加了残疾和依赖性，从而提高了医疗保健成本。然而，肌肉质量——肌肉减少症的一个重要组成部分——却不容易诊断。最近，人们对超声评估肌肉的兴趣有所增加。本文介绍了肌肉弹性成像作为一种评估肌肉质量参数的可行、简单且廉价的工具。本文描述了肌肉弹性成像的基本原理，以及不同的弹性成像技术和一些技术注意事项。此外，还提出了实用指南的建议，并强调了影响肌肉硬度的因素。
