MSK MR imaging applications are making the transition rapidly from 1.5T to 3T. Initial experience in the knee suggests that the higher SNR provides technical improvement in routine clinical imaging with the potential for greater accuracy in the diagnosis of articular cartilage injury. Similarly, initial experience with 3T MR imaging in the evaluation of the hip and small joints of the hand and wrist has been positive. In other joints, clinical development has been limited by the lack of availability of dedicated surface coils, and sensitivity of 3TMR imaging to artifact. The clinical impact of this technology remains uncertain because no published controlled clinical trial has evaluated the impact of 3T MR imaging on diagnostic outcomes. In addition to clinical application, 3T MR imaging has an important role for furthering translational research in MSK diseases through the development of new molecular and functional MR imaging techniques.
肌肉骨骼磁共振成像应用正在迅速从1.5T向3T过渡。膝关节的初步经验表明，更高的信噪比在常规临床成像中带来了技术改进，有可能在关节软骨损伤诊断中实现更高的准确性。同样，3T磁共振成像在评估髋关节以及手部和腕部小关节方面的初步经验也是积极的。在其他关节中，临床进展受到专用表面线圈可用性的缺乏以及3T磁共振成像对伪影敏感性的限制。由于尚无已发表的对照临床试验评估3T磁共振成像对诊断结果的影响，这项技术的临床影响仍不确定。除了临床应用外，3T磁共振成像通过开发新的分子和功能磁共振成像技术，在推进肌肉骨骼疾病的转化研究方面具有重要作用。
