摘　　要：目的探讨肋骨切线位及正位DR双能量减影技术骨组织图像在肋骨骨折中诊断价值。材料与方法分析本院收治证实肋骨骨折患者60例,以复查DR片显示骨折端骨痂形成为骨折的金标准,均签写知情同意书,采用美国GE公司Definium 6000型双板DR检查,双能量减影法摄正、切线位胸片.每例患者分别获得标准DR图像、软组织像及骨组织像及肋骨切线位标准图像、软组织像及骨组织像。比较两组标准图像和骨组织图像对肋骨骨折的显示率,采用Cochran Armitage趋势检验进行统计分析。确定P<0.05为差异有统计学意义。结果本组60例肋骨切线位骨组织像显示肋骨骨折48例,常规DR切线位42例,骨组织减影图像正位40例,常规DR正位图像显示肋骨骨折36例。肋骨切线位+正位骨组织减影图像显示58例。结论肋骨骨折较好显示体位胸部正位+切线位,较好显示方法双能量减影骨组织图像。胸部正位+肋骨切线位DR双能量减影技术骨骼像可提高肋骨骨折诊断准确率。Purpose： To investigate the value of tangential position and dual emergy subtraction in the diagnosis of fracture of rib. Materials and Methods： There are 60 eases diagnosised of rib fractures, Each of them has A-P position, tangential projection and dual emergy subtraction film. Each of them has A-P position image, tangential projection image, the bone image , the soft tissue image and the tangential bone image. Analysis the rate of thediagnosis of fracture of rib of the A-P position, tangential projection and dual emergy subtraction film. Using Cochran Armitage trend test for statistical analy- sis. Determine the P 〈 0. 05 for the difference was statistically significant. Results： In the 60 cases , the cases of rib frac- tures were found with tangential projection image is 48, with A-P position image is 42, with tangential bone image is 40, with bone image is 36, with A-P position and tangential projection image is 60. Conclusion ： The best display position of rib frac- tures are A-P position ＋ tangent position, he best method of rib fractures is dual emergy subtraction film. The way to use A- P position and tangential bone image together can improve the rate of the diagnostic of rib fractures.
