摘要
目的:探讨多层螺旋CT三维重建技术在腕关节损伤中的应用价值。方法:14例腕关节创伤患者,全部行X线摄片和多层螺旋CT薄扫、三维重建及多平面重建,分析各种方法对骨折或脱位的显示情况。结果:14例腕关节损伤多层螺旋CT共发现19处骨折脱位,而X线平片只发现13处,MPR可以很好显示脱位的方向和程度,骨折线走向和移位及周围软组织的情况。SSD可以直观的多角度观察骨折立体关系和脱位情况。结论:多层螺旋CT的MPR和SSD两种重建方法可提高腕关节损伤的诊断准确性,有利于临床医师选择治疗方案和制定手术计划。
Objective： To evaluate the role of 3D imaging of Multi,slice Spiral CT in the diagnosis of wrist joint damage. Methods： The display images of 14 cases of wrist joint damage are compared with x ray; Multi-slice Spiral CT, 3D reconstruction and muhiplanar reconstruction. Results： 19 fracture dislocation in wrist joint damage were found in Muhislice Spiral CT, only 13 fracture dislocation were found in x ray, MPR can display orientation and degree of the dislocation, fracture line i displacement and surrounding soft tissue well. bone fracture was well demonstrated stereoscopically and could be viewed from any desired plane by SSD. Conclusion： Combination of all muhislice spiral CT techniques can increase the accuracy of diagnosis. These techniques will be of great benefit forsurgeons to choose surgical intervention methods and draft surgical schemes.
