OBJECTIVE
This article reviews the neoplastic and nonneoplastic abnormalities of the musculoskeletal system that contain high signal intensity on T1-weighted MRI. The physical properties accounting for the increased signal intensity as well as the key clinical and imaging characteristics of each entity are discussed.
CONCLUSION
Recognition of high signal intensity within musculoskeletal lesions on T1-weighted MRI can limit the differential diagnosis and can also have important clinical implications.
目的
本文综述了在T1加权磁共振成像（MRI）上呈现高信号强度的肌肉骨骼系统的肿瘤性和非肿瘤性异常情况。文中讨论了导致信号强度增加的物理特性以及每个实体的关键临床和影像学特征。
结论
认识到T1加权MRI上肌肉骨骼病变内的高信号强度可限制鉴别诊断范围，并且还可能具有重要的临床意义。
