Ultrasound (US) imaging plays a crucial role in the assessment of musculoskeletal (MSK) disorders. Several quantitative tools are offered by US systems and add information to conventional US imaging. This article reviews the quantitative US imaging tools currently available in MSK radiology, specifically focusing on the evaluation of elasticity with shear-wave elastography, perfusion with contrast-enhanced US and noncontrast superb microvascular imaging, and bone and muscle mass with quantitative US methods. Some of them are well established and already of clinical value, such as elasticity and contrast-enhanced perfusion assessment in muscles and tendons. MSK radiologists should be aware of the potential of quantitative US tools and take advantage of their use in everyday practice, both for clinical and research purposes.
超声（US）成像在肌肉骨骼（MSK）疾病的评估中起着至关重要的作用。US 系统提供了几种定量工具，并为常规 US 成像增加了信息。本文综述了目前在 MSK 放射学中可用的定量 US 成像工具，特别是重点介绍了剪切波弹性成像的弹性评估、对比增强超声和非对比性超微血流成像的灌注以及定量 US 方法的骨和肌肉质量评估。其中一些已经得到了很好的确立，并具有临床价值，例如肌肉和肌腱的弹性和对比增强灌注评估。MSK 放射科医生应该意识到定量 US 工具的潜力，并利用它们在日常实践中的应用，无论是出于临床还是研究目的。
