【摘要】 目的:探讨64排螺旋CT多平面重建(MPR)及容积再现(VR)图像在面中部复杂骨折中的临床应用价值。方法:对46例面中部复杂骨折患者进行64排螺旋CT薄层扫描,容积数据传送到工作站进行MPR和VR三维成像。结果:46例面中部366处骨折,MPR图像对面中部各部位骨折的显示率为100%;VR图像对颧骨、颧弓、下颌骨骨折的显示率为100%,对上颌骨骨折的显示率为94.3%、眼眶骨折为93.2%、筛骨骨折为13.0%、蝶骨骨折为55.6%,平均显示率为86.3%。VR图像能够通过图像旋转、切割等功能从不同方向观察骨折的位置、范围、骨碎块的移位,了解骨折线的走行及外伤所致的畸形情况。结论:MPR结合VR成像对面中部骨折的诊断治疗具有很高的临床应用价值。64排螺旋CT图像能提高对深部细微骨折的显示。更多还原

【Abstract】 Objective:To evaluate the value of clinical application of multiplanar reconstruction (MPR) and volume rendering (VR) with 64-slice spiral CT in the complex midfacial fracture.Method:Forty-six patients with the complex midfacial fracture were examined with 64-slice spiral CT, then MPR and VR were performed in work station.Result:Of 46 patients, there are 366 fractures. MPR imaging clearly showed all(the rate were 100%). VR imaging could show all zygomatic fracture and mandidular fracture(the rate were 100%), but the showed rate were 94.3% in maxillary fracture, 93.2% in orbital fractures,13.0% in ethmoid fractures,55.6% in sphenoid bone fracture,the mean rate were 86.3%. VR imaging could show the fracture location, range, fragment displacement from different direction by rotating picture and demonstrate the course of fracture line and deformities caused by fracture.Conclusion:MPR imaging combination with VR imaging has important clinical value in diagnosing the complex midfacial fracture. 64 slice CT may improve displaying tiny and deep fracture.更多还原
