The purpose of this article is to provide a practice-focused review of the clinical application of advanced acceleration techniques for rapid musculoskeletal MRI examinations. Parallel imaging, simultaneous multislice acquisition, compressed sensing-based sampling, and synthetic MRI techniques provide unprecedented opportunities for rapid musculoskeletal MRI examinations. For 2D and 3D fast spin-echo and turbo spin-echo pulse sequences, acceleration factors between 3 and 8 can be realized in clinical practice, amounting to a time savings of 66-85% when compared with unaccelerated acquisitions.
本文旨在提供一份以临床应用为重点的综述，探讨加速技术在快速肌肉骨骼 MRI 检查中的应用。并行成像、单次激发多层面采集、基于压缩感知的采样以及合成 MRI 技术为快速肌肉骨骼 MRI 检查提供了前所未有的机会。对于 2D 和 3D 快速自旋回波和涡轮自旋回波脉冲序列，在临床实践中可以实现 3 到 8 倍的加速因子，与未加速采集相比，可节省 66-85%的时间。
