摘　　要：传统CT诊断骨骼肌肉系统疾病,尤其是骨髓、肌腱和韧带等病变的价值有限。随着性能的改进及对辐射剂量的有效控制,第二代双源CT(DSCT)已初步在骨骼肌肉系统疾病的诊断,尤其在骨髓、肌腱和韧带病变以及痛风石检出中显示了独特的应用价值。本文对第二代DSCT双能量成像的原理,其在骨骼肌肉系统中的临床应用、研究进展以及存在问题与不足等予以综述。The diagnostic value of conventional CT for musculoskeletal system, especially bone marrow, tendon and liga- ment diseases, etc is relatively limited. However, with the improvement of performance and effective control of radiation dose, the second generation definition flash dual-source CT （DSCT） has shown unique application value in musculoskeletal system, including bone marrow, tendon and ligament lesions, as well as gout stone and so on. The principle, clinical appli cations, research progresses, problems and shortcomings of the second generation DSCT imaging in musculoskeletal system were reviewed in this article.
