: To evaluate dual-energy computed tomography (DECT) in comparison with conventional CT for periprosthetic bone and surrounding soft tissues in total hip arthroplasty (THA). : Two authors independently screened titles and abstracts for eligibility, discussing any disagreements with a third author for final decisions. The articles were categorized into two main groups: those focusing on periprosthetic bone and those on blood vessels or pelvic organs. : A total of 37 articles were selected to be included in this systematic review. : Our systematic review reveals significant variability in the use of DECT for periprosthetic bone and soft tissue imaging, due to differences in equipment, protocols, and clinical settings. While many studies indicate that virtual monochromatic imaging (VMI), especially when combined with metal artifact reduction (MAR), improves image quality, there is no consensus on optimal energy levels. Future research should focus on large-scale, multicenter studies with standardized protocols to compare reconstruction techniques, energy levels, and combined MAR-VMI use.
评估双能计算机断层扫描（DECT）与传统CT在全髋关节置换术（THA）中假体周围骨及周围软组织方面的差异。：两位作者独立筛选标题和摘要以确定其是否符合要求，如有分歧则与第三位作者讨论以做出最终决定。文章被分为两个主要组：关注假体周围骨的文章和关注血管或盆腔器官的文章。：总共37篇文章被选入本系统评价。：我们的系统评价显示，由于设备、方案和临床环境的差异，DECT在假体周围骨和软组织成像中的使用存在显著差异。虽然许多研究表明虚拟单色成像（VMI），尤其是与金属伪影减少（MAR）相结合时，可提高图像质量，但对于最佳能量水平尚无共识。未来的研究应集中在采用标准化方案的大规模、多中心研究上，以比较重建技术、能量水平以及MAR-VMI联合使用的情况。
