Regulatory approval of ultrahigh field (UHF) MR imaging scanners for clinical use has opened new opportunities for musculoskeletal imaging applications. UHF MR imaging has unique advantages in terms of signal-to-noise ratio, contrast-to-noise ratio, spectral resolution, and multinuclear applications, thus providing unique information not available at lower field strengths. But UHF also comes with a set of technical challenges that are yet to be resolved and may not be suitable for all imaging applications. This review focuses on the latest research in musculoskeletal MR imaging applications at UHF including morphologic imaging, T, T∗, and T mapping, chemical exchange saturation transfer, sodium imaging, and phosphorus spectroscopy imaging applications.
超高频（UHF）磁共振成像扫描仪的监管批准为肌肉骨骼成像应用开辟了新的机会。UHF MR 成像在信噪比、对比噪声比、光谱分辨率和多核应用方面具有独特的优势，因此提供了在较低场强下无法获得的独特信息。但 UHF 也带来了一系列尚未解决的技术挑战，可能并不适用于所有成像应用。本综述重点介绍了 UHF 下肌肉骨骼磁共振成像应用的最新研究，包括形态成像、T、T*和 T 映射、化学交换饱和转移、钠成像和磷波谱成像应用。
