Abstract:: Abstract: Gemstone spectral CT is a new type of CT transformed from traditional CT. The tube can take advantage of the high- and low-energy X-ray instantaneous switching, which not only makes up for the shortcomings of conventional CT, but also helps to further distinguish the components of different tissues. In recent years, energy spectrum CT has been used for the diagnosis of skeletal system lesions, such as diagnosis of osteoporosis, examination after arthroplasty, differential diagnosis of gout stone, differential diagnosis among myeloma, bone metastasis and bone island, diagnosis of bone injury, and diagnosis of tendon lesions. Some progresses have been made in the diagnosis of skeletal system lesions with energy spectrum CT, and the application of gemstone spectral CT in skeletal system is worthy to be further investigated. Although the diagnosis of bone mineral density with energy spectrum CT is still inconclusive, the comprehensive evaluation showed that energy spectrum CT has great values in the evaluation of skeletal system diseases. Herein the application of energy spectrum CT in skeletal diseases is reviewed from several aspects.
