摘　　要：目的:探讨数字断层融合摄影(DTS)技术在腕舟骨骨折诊断中的应用价值。方法:搜集30例临床怀疑腕舟骨骨折的患者,所有患者均行普通DR、DTS及CT检查,以CT检查结果为标准,比较普通DR与DTS的诊断符合率、敏感度及特异度。结果:DTS对腕舟骨骨折的诊断符合率为86.67%(26/30),显著高于普通DR(56.67%,17/30),差异具有统计学意义(P<0.05)。DTS检查对腕舟骨骨折的诊断敏感度为88.89%,显著高于普通DR(敏感度为59.26%),差异具有统计学意义(P<0.05)。DTS检查对腕舟骨骨折的诊断特异度为66.67%,普通DR为33.33%,两者之间差异无统计学意义(P>0.05)。结论:DTS对腕舟骨骨折的诊断效能高于普通DR,能清晰显示骨折情况,具有一定的临床应用价值。Objective:To explore the application value of digital tomosynthesis(DTS) in diagnosing wrist scaphoid fractures.Methods:Thirty patients with clinically suspected wrist scaphoid fractures underwent standard digital radiography(DR),DTS,and computed tomography(CT) examinations.According to CT examination results as the gold standard, the diagnostic accuracy, sensitivity, and specificity of ordinary DR and DTS were compared.Data analysis was performed using the χ~2 test.Results:The diagnostic accuracy of DTS in wrist scaphoid fractures was 86.67%(26/30),which was significantly higher than that of ordinary DR(56.67%,17/30),and the difference was statistically significant(P<0.05).The sensitivity of DTS in wrist scaphoid fractures was 88.89%,which was significantly higher than that of ordinary DR(59.26%),with a significant difference(P<0.05).The specificity of DTS was 66.67%,and that of ordinary DR was 33.33%.The two groups had no statistical difference(P>0.05).Conclusion:The diagnostic ability of DTS for wrist scaphoid fracture is better than that of ordinary DR.DTS can display the fracture situation, which can be used as a good examination for the diagnosis of wrist scaphoid fracture with specific clinical application value.
