美国食品和药物管理局 (FDA) 以及欧洲监管机构批准超高场 (7T) 磁共振扫描仪用于临床,为更广泛的临床应用打开了大门 1, 2 特别是 MR 供应商发布了临床 UHF 扫描仪。尽管临床MR系统大多数为1.5和3T系统,但许多大型医院和学术研究中心已经探索了UHF3-9的肌肉骨骼MR应用。与较低场强扫描仪相比,UHF 7T 扫描仪具有一系列独特的优势,但它们也面临着一系列技术和安全挑战。是否使用 UHF 扫描仪的选择更加细致,并且取决于预期应用,因此,了解临床使用 7T 系统的优点、缺点和当前挑战非常重要。
The approval of ultra-high field (7T) magnetic resonance scanners for clinical use by the US Food and Drug Administration (FDA), and the European regulatory authority have opened the doors for more widespread clinical adoption1, 2 particularly with the release of clinical UHF scanners by MR-vendors. Although the majority of clinical MR systems are 1.5, and 3T systems, a number of large hospitals and academic research centers have explored musculoskeletal MR applications at UHF3–9. UHF 7T scanners provide a unique set of advantages over lower field strength scanners, but they also come with a set of technical and safety challenges. The choice of whether to use a UHF scanner is more nuanced and based on the intended application and thus, it is important to understand the advantages, disadvantages and current challenges of 7T systems for clinical use.
