The purpose of this article is to provide a practice-focused review of accelerating musculoskeletal MRI with the use of widely accessible techniques and to assess the effects of such acceleration on the value of musculoskeletal MRI. Echo-train compaction with fast radiofrequency pulses, high gradient performance modes, and high receiver bandwidth, as well as basic phase undersampling techniques, affords at least twofold acceleration of musculoskeletal MRI examinations while retaining image quality, comprehensiveness, and diagnostic performance. Optimized efficiency is a cornerstone for adding value to musculoskeletal MRI.
本文旨在提供一个以实践为重点的综述，介绍使用广泛应用的技术来加速肌肉骨骼 MRI，并评估这种加速对肌肉骨骼 MRI 价值的影响。采用快速射频脉冲、高梯度性能模式和高接收带宽的回波列车压缩以及基本的相位欠采样技术，至少可以将肌肉骨骼 MRI 检查的速度提高两倍，同时保持图像质量、全面性和诊断性能。优化效率是为肌肉骨骼 MRI 增加价值的基石。
