摘　　要：目的探讨128层螺旋CT扫描容积重建诊断肋骨骨折的临床价值。方法回顾性分析100例378根肋骨及20根肋软骨骨折病例,采用薄层(0.625mm)重组、容积再现(VR)重建技术进行肋骨及肋软骨重建,并在工作站上进行多角度、全方位动态观察。结果 100例肋骨发现320根378处骨折,其中多发骨折85例305根,单发性骨折15例;单侧肋骨骨折78例257根,双侧骨折22例共121根;肋软骨骨折20例,不全性骨折45根。合并肺挫伤35例,气胸26例,血气胸18例,脾挫裂伤8例、肝挫裂伤3例。结论胸部外伤患者行128层螺旋CT常规扫描后,薄层重组结合容积重建对肋骨骨折及其并发症的诊断有非常重要的价值。Objective To investigate the value of volume vendering after 128-slice spiral CT in the diagno-sis of rib fracture. Methods The clinical data of 100 patients （378 rib fractures and 20 costalcartilages fractures） were retrospectively analyzed. The thin-slice reconstruction （0.652 mm）, volume vendering （VR） were applied for the reconstruction of rib and costalcartilages. Multi-angel, comprehensive, dynamic observation in the workstation was performed. Results A total of 378 rib fractures in 320 ribs were found, including multiple rib fracture in 305 ribs in 85 patients, comminuted rib fracture in 15 fibs in 15 patients, of which 257 fractured ribs were on the same side （in 78 patients） and 121 were on two sides （in 22 patients）. A total of 20 patients with costaleartilages fractures were found, with 45 ribs of incomplete rib fracture. Thirty-five patients were found with lung contusion, 26 with pneumothorax, 18 with hemopnemothorax, 8 with dampened spleen and 3 with dampened liver. Conclusion Thin-slice reconstruction and volume vendering after 128-slice spiral CT scan has very important value in the diagnosis of ribs fracture and com-plications in patients with chest tramna.
