64排螺旋CT三维重建技术评估稳定性骨盆骨折的应用价值

Clinical Application of 64 Multi-detector Helical CT in Evaluation of Stable Pelvic Fracture

摘要: 目的:探讨64排螺旋CT对稳定性骨盆骨折的评估价值。方法:收集2009年7月~2012年8月连续44例经64排螺旋CT检查确诊为稳定性骨盆骨折的门急诊患者影像数据,并重新采用多层面重建(MPR);最大密度投影(MIP)和容积重建(VR)等多种后处理技术进行了回复性分析。结果:全部病例均为Tile A型,其中16例A1型和28例A2型,MDCT 3D可以准确评估骨盆骨折的部位、类型、程度及并发症等,符合临床诊断要求。结论:64排螺旋CT联合应用多种重建技术对稳定性骨盆骨折的评价是可靠和准确的,尤其对并发症的评估可以为临床提供更多的诊断信息,能够为临床采取及时有效的治疗提供更准确可靠的影像依据。

Abstract: Objective: To evaluate the diagnostic value of 64 multi-detector helical CT in stable pelvic fracture. Methods: 44 cases of stable pelvic fracture were performed with 64-MDCT. The data was transmitted to ADW4.3 workstation, and reconstructed by MPR, MIP, VR and generally analyzed with original axial images. Results: All the 44 cases are Tile A classification, including 16 cases of Tile A1 and 28 cases of A2. All fractures were demonstrated clearly by MDCT, and it can reveal the location, types, level and complication of fracture change. Conclusion: 64-MDCT is reliable and accurate in evaluating stable pelvic fractures, gradually becomes necessary modality examination in patients after trauma of pelvis.
