Abstract
The technology of musculoskeletal magnetic resonance imaging (MRI) is advancing at a dramatic rate. MRI is now done at medium and higher field strengths with more specialized surface coils and with more variable pulse sequences and postprocessing techniques than ever before. These innumerable technical advances are advantageous as they lead to an increased signal-to-noise ratio and increased variety of soft-tissue contrast options. However, at the same time they potentially produce more imaging artifacts when compared with past techniques. Substantial technical advances have considerable clinical challenges in musculoskeletal radiology such as postoperative patient imaging, cartilage mapping, and molecular imaging. In this review we consider technical advances in hardware and software of musculoskeletal MRI along with their clinical applications.
摘要
肌肉骨骼磁共振成像（MRI）技术正在迅速发展。与以往相比，现在的 MRI 采用中高磁场强度、更专业的表面线圈，以及更多变化的脉冲序列和后处理技术。这些无数的技术进步是有利的，因为它们提高了信号噪声比，并增加了更多的软组织对比选择。然而，与此同时，与过去的技术相比，它们也可能产生更多的成像伪影。在肌肉骨骼放射学中，大量的技术进步带来了相当大的临床挑战，如术后患者成像、软骨绘图和分子成像。在这篇综述中，我们考虑了肌肉骨骼 MRI 的硬件和软件技术进步及其临床应用。
