16层螺旋CT三维重建与DR平片对外伤性肋骨骨折的诊断探究

目的:研究16层螺旋CT三维重建与DR平片对外伤性肋骨骨折的诊断价值。方法:对白求恩国际和平医院收治的72例外伤性肋骨骨折患者分别行16层螺旋CT三维重建及DR平片检查。统计患者骨折部位,比较两种检查方法肋骨骨折确诊率及骨折合并症检出情况。结果:肋骨骨折多发高于单发,且多发生于第4~10肋骨及腋段,16层螺旋CT三维重建对肋骨骨折诊断准确率为97.2%,DR平片诊断准确率为80.3%,16层螺旋CT三维重建诊断率明显高于DR(x2=19.15,P<0.01);DR平片漏诊的肋骨骨折主要位于肋软骨(占58.1%),16层螺旋CT三维重建发现其他部位骨折19处及肺部合并症16例。结论:16层螺旋CT薄层诊断肋骨骨折极大提高了诊断准确率,在隐匿性肋骨骨折及并发症方面其临床价值明显优于DR平片。

Clinical research on diagnosis of traumatic rib fractures by multislice CT VRT and DR plain film

Objective： To research the value of diagnosis of traumatic rib fractures by multislice CT VRT and DR plain film. Methods： Seventy-two cases of traumatic rib fracture patients were diagnosed by DR film and multislice CT VRT. Results： Multiple rib fractures than single, most of them occurred in the 4-10 ribs and axillary segment, 97.2% of 16-slice spiral CT three- dimensional reconstruction of patients with rib fracture diagnosis rate significantly higher than DR plain film diagnosis rate 80.3% （x2=19.15, P〈0.01）, DR plain film missed rib fractures are mainly located in the costal cartilage （58.1%）, 16-slice spiral CT reconstruction is still found 19 other fractures and lung complications 16cases. Conclusion： 16-slice CT the thin layer VRT diagnosis of rib fractures greatly improves the diagnostic accuracy.
