副鼻窦骨折的64排螺旋CT应用价值

Application of 64 Multi-Detector Helical CT in Evaluation of Fracture of Accessory Nasal Cavity

摘要: 目的:探讨64排螺旋CT对副鼻窦骨折的诊断价值。方法:2005年9月至2007年2月对连续188例门急诊颜面部外伤后疑似副鼻窦骨折患者进行了64排螺旋CT检查,采用多层面重建(MPR);最大灰度重建(MIP)和容积显示(VR)等多种后处理技术并结合原始横轴位图像进行综合分析。结果:MDCT共显示副鼻窦骨折患者共69例,可以准确评估各副鼻窦骨折的部位、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副鼻窦骨折的评价是可靠和准确的,颜面部外伤患者疑似副鼻窦骨折时应作为必要的影像检查方法,可为临床采取及时有效的治疗提供准确的信息。

Abstract: Objective: To evaluate the diagnostic value of 64 multi-detector helical CT in fracture of accessory nasal cavity.Methods: 188 cases suspected fracture of accessory nasal cavity were performed with 64-MDCT.The data was transmitted to ADW4.2 workstation,and reconstructed by MPR,MIP,VR and generally analyzed with original axial images.Results: All the 69 fracture of accessory nasal cavity were demonstrated clearly by MDCT,and it can revealing the location,types,level and complication of fracture change.Conclusion: 64-MDCT is reliable and accurate in evaluating fracture of accessory nasal cavity,gradually become necessary modality examination in patients after trauma of facial surface.
