摘　　要：X线数字断层融合技术（DTS）由于成像原理与CT不同，DTS在矢状面和冠状面上有着比CT更好的空间分辨率，又因DTS经重建后生成的是“层”影像，所以在区别3D组织结构方面优于普通X线摄影，可以为临床诊断提供3D信息，同时它的辐射剂量显著低于CT。近年来，DTS在骨骼系统成像中的应用取得了较大进展，现就DTS在骨折诊断、骨折愈合评价、椎骨骨质评估与骨折风险预测、关节脱位诊断、骨质侵蚀评价和关节置换术后评价等方面的研究进展以及将来可能的应用方向进行综述。Because X-ray digital tomosynthesis （DTS） imaging principle is different from that of CT, DTS has better spatial resolution than that of CT in sagittal and coronal planes, and since DTS is reconstructed to generate ＂layer＂ images, its power in the aspect of distinguishing 3D tissue structures is superior to that of general X-ray photography, so DTS can provide 3D information for clinical diagnosis; its radiation dose is markedly lower than that of CT. In recent years, DTS has made progress in the application of skeletal system imaging; the research progress and the possible direction of future application of DTS in bone fracture diagnosis, fracture healing estimation, vertebral bone quality assessment and fracture risk prediction, joint dislocation diagnosis, bone erosion evaluation and postoperative arthroplasty assessment were summarized.
