In 2017, a whole-body 7T magnetic resonance imaging (MRI) device was given regulatory approval for clinical use in both the EU and United States for neuro and musculoskeletal applications. As 7 Tesla allows for higher signal-to-noise , which results in higher resolution images than those obtained on lower-field-strength scanners, it has attracted considerable attention from the musculoskeletal field, as evidenced by the increasing number of publications in the last decade. Besides morphological imaging, the quantitative MR methods, such as T2, T2*, T1ρ mapping, sodium imaging, chemical-exchange saturation transfer, and spectroscopy, substantially benefit from ultrahigh field scanning. In this review, we provide technical considerations for the individual techniques and an overview of (mostly) clinical applications for the assessment of cartilage, tendon, meniscus, and muscle. The first part of the review is dedicated to morphological applications at 7T, and the second part describes the most recent developments in quantitative MRI at 7T.
2017年，一台全身7T磁共振成像（MRI）设备在欧盟和美国均获得监管批准，可用于神经和肌肉骨骼方面的临床应用。由于7特斯拉能实现更高的信噪比，相较于低场强扫描仪所获得的图像，其能生成分辨率更高的图像，因此在过去十年中，出版物数量不断增加，这表明它已引起肌肉骨骼领域的广泛关注。除形态学成像外，定量磁共振方法，如T2、T2*、T1ρ成像、钠成像、化学交换饱和转移和波谱分析，也从超高场扫描中受益匪浅。在本综述中，我们针对评估软骨、肌腱、半月板和肌肉的各项技术提供了技术考量，并概述了（主要是）临床应用情况。综述的第一部分致力于7T下的形态学应用，第二部分描述了7T定量MRI的最新进展。
