双源CT结合多平面重建与容积再现三维重建技术评价肋骨骨折

Dual-source CT with multiplanar reconstruction and volume rendering three-dimensional reconstruction in the evaluation of rib fractures

背景:依靠胸部摄片诊断肋骨骨折常导致误诊和漏诊。目的:分析双源CT结合三维重建技术在肋骨骨折中的应用价值。方法:使用双源CT对65例肋骨骨折患者进行薄层扫描,将数据发送至工作站行多平面重建、容积再现技术,得到肋骨骨折高清晰度的三维图像后,从不同角度观察骨折线走行、骨折移位及成角情况。结果与结论:双源CT结合三维重建图像清晰显示65例患者286根骨折,其中52例保守治疗,其余13例行切开复位、内固定治疗。制定手术方案时均参考了三维重建图像,所显示的骨折部位、移位、成角等情况与术中所见一致。提示双源CT能明确诊断肋骨骨折,多平面重建和容积再现技术互相补充对诊断肋骨骨折及指导治疗方案有明显的优势。

BACKGROUND：Diagnosis of rib fractures relying on the chest radiograph diagnosis often leads to misdiagnosis.OBJECTIVE：To investigate the application of dual-source CT with three-dimensional reconstruction in rib fractures.METHODS：Sixty-five patients with rib fractures were scanned with dual-source CT.The data were sent to the workstation line of multi-planar reconstruction using volume rendering technique,to obtain high-resolution three-dimensional images of rib fractures,and to observe the fracture line courses,fracture displacement and angulation of the situation from different angles.RESULTS AND CONCLUSION：The combination of dual-source CT and three-dimensional reconstruction images clearly showed 286 fractures in 65 patients,including 52 cases of conservative treatment,and the remaining 13 cases of surgery.The surgery programs in all patients were developed with reference to three-dimensional reconstruction images showing the fracture position,displacement,angulation,etc.,consistent with the intraoperative findings.Dual-source CT can confirm the diagnosis of rib fractures,and multi-planar reconstruction and volume rendering techniques complement each other in the diagnosis and guiding treatment of rib fractures which have a distinct advantage.
