目的探讨SPECT/CT显像对术后骨折愈合程度的评价价值.方法回顾性分析骨折金属固定术后,X线检查无法明确骨折愈合程度而行SPECT/CT显像的28例患者(男13例,女15例,平均年龄45.3岁)资料,观察SPECT/CT图像特征.以骨显像剂通过骨折端判断为骨折可延迟愈合,否则为不愈合;同时观察螺钉周围是否有放射性浓聚,以判断螺钉是否松动.最终结果均经手术或X线检查随访证实.结果 28例骨折患者中,可延迟愈合者(随访证实)15例,不愈合者(手术证实)13例;6例患者13枚螺钉周围有放射性异常浓聚,提示螺钉松动(手术证实).结论 SPECT/CT显像可评估骨折愈合情况,对探寻骨折愈合不佳原因也有一定辅助作用.

Objective To explore the diagnostic value of SPECT/CT on fracture healing.Methods A total of 28 patients (13 males,15 females; average age 45.3 years) with fracture were enrolled.All underwent metal fixation.SPECT/CT scans were performed at least 6 months after the metal fixation.X-ray examination before SPECT/CT showed equivocal fracture healing.The fracture delayed union or nonunion were judged by degree of uptake as well as uptake pattern around fracture site.Final diagnosis was confirmed by surgery or follow-up X-ray film.Results Among 28 patients,15 showed delayed union (confirmed by follow-up),and 13 showed nonunion (confirmed by surgery).There were 13 screws in 6 patients showed abnormal uptake,suggesting screw loose (confirmed by surgery).Conclusions SPECT/CT imaging could be of clinical significance in assessing fracture healing.
