近年来，定量超声（QUS）方法越来越多地用于骨质疏松症的评估。新技术的发展已经加速，今天，许多不同的设备都可以在市场上买到。为了平衡评估方法，需要认识到两个问题：QUS有不同的应用，有不同的QUS方法和设备。关于应用，目前QUS方法的主要应用领域是骨折风险评估。为了用于监测和诊断，需要进一步的进展和研究。关于各种方法，需要认识到测量参数声速（SOS）和宽带超声衰减（BUA）之间的差异，不同的测量地点和采用的不同技术。此外，一些早期的设备已经得到了很好的验证，而较新的机器可能具有更先进的技术-然而，需要进行测试和验证。无论选择何种器械，充分和定期执行的质量保证措施以及对该方法的一般和器械特定限制的深入了解至关重要。如果使用得当，QUS设备可以在骨质疏松症的评估中发挥重要作用。
In recent years Quantitative Ultrasound (QUS) approaches have increasingly been used for the assessment of osteoporosis. The development of new technologies has accelerated, and today a number of different devices are commercially available. For a balanced evaluation of the approaches one needs to recognise two issues: There are different applications for QUS, and there are different QUS approaches and devices. Regarding the applications, today the main area for use of QUS approaches is the assessment of a fracture risk. For use in monitoring and diagnosis, further advances and studies are required. Regarding the various approaches, one needs to recognise the differences between the measurement parameters Speed Of Sound (SOS) and Broadband Ultrasound Attenuation (BUA), the different measurement sites and the different technologies employed. Moreover, some of the earlier devices are very well validated whereas newer machines may feature more advanced technology--which, however, needs to be tested and validated. Whatever the choice of a device will be, adequate and regularly performed measures for quality assurance and in-depth knowledge on the general and device specific limitations of the approach are of substantial importance. When used appropriately, QUS devices can play an important role in the assessment of osteoporosis.
