摘　　要：目的探讨X线数字断层融合技术（Digitaltomosynthesis，DTS）在诊断肋骨骨折中的应用价值。方法对可疑肋骨骨折的32例患者同时进行X线平片、DTS及多层螺旋CT（Multi—slicespiralCT，MSCT）成像，分析并比较其结果。结果DTS和MSCT的图像质量评分差异无统计学意义（P=0．183），均明显高于X线平片的评分（P〈0．01）。X线平片和DTS对肋骨骨折的检出率分别为72．8％和93．5％，DTS对肋骨骨折的检出率明显高于X线平片（P〈0．01）。结论DTS的图像质量佳，对肋骨骨折的检出率高，是诊断肋骨骨折的理想方法。Objective To explore the application value of digital tomosynthesis （DTS） in the diagnosis for rib facture. Methods X-ray, DTS and multi-slice spiral CT （MSCT） were performed on 32 cases of suspected rib fracture. The results of the scanning were analyzed and compared. Results There was no significant difference showed in the image quality score of DTS and MSCT （P=-0.183）. The image quality scores of DTS and MSCT were better than those of X- ray （P〈 0.01）. The diagnosis rate of DTS was significant higher than that of X-ray （93.5% VS 72.8%, 2a=14.005, P〈 0.001）. Conclusion DTS displayed high image quality and high diagnosis rate of rib fracture. DTS can be considered as an ideal diagnosis approach of rib fracture.
