Conventional CT of the postoperative patient with metal hardware is frequently limited by beam-hardening artifacts. With the evolution of 3D CT, CT is an increasingly effective means of examining the postsurgical patient for the integrity of their hardware and the course of their healing.
Potential postsurgical complications such as nonunion, osteolysis, infection, and heterotopic ossification are all well assessed by 3D CT.
术后植入金属硬件患者的传统CT常受线束硬化伪影限制。随着3D CT的发展,CT越来越成为检查术后患者硬件完整性及其愈合过程的有效手段。
3D CT能很好地评估潜在的术后并发症,如骨不连、骨质溶解、感染和异位骨化。
