目的探讨64排螺旋CT三维重建在埋伏牙诊断中的价值。方法对28例颌骨埋伏牙行多层螺旋CT扫描,采用MPR、MIP和VR3种方式重建图像,显示埋伏牙的形态、位置及其与邻牙的关系。结果三维CT重建图像可以从多个角度完整清晰地显示28例患者埋伏牙的位置、形态、大小、方向及与邻牙的关系。结论 64排CT三维重建能全方位地展示埋伏牙,为临床诊断和治疗提供可靠的信息指导。
Objective To investigate the value of 64-slice spiral CT three-dimensional reconstruction in the diagnosis of impacted teeth. Methods Twenty - eight cases of mandibular jaw implanted with multi - slice spiral CT were reconstructed by using MPR, MIP and VR3 methods to show the morphology and location of the impacted tooth and its relationship with its adjacent teeth. Results Three-dimensional CT reconstruction images can show the location, shape, size, orientation and the relationship between the adjacent teeth of the ambush teeth in 28 patients completely and clearly from multiple perspectives. Conclusion 64-slice CT three-dimensional reconstruction can display all-directional ambush teeth and provide reliable information guidance for clinical diagnosis and treatment.
