目的评价16层螺旋CT三维表面遮盖法重建技术(surface shaded display,SSD)和多层面重建技术(multiplanar reconstruction,MPR)在鼻骨骨折中的应用价值。方法分析195例鼻骨骨折的MPR及SSD表现。结果195例均经MPR和SSD技术重建图像。MPR对鼻骨骨折显示良好,195例均显示清晰并能判断骨折类型;SSD在显示骨折类型方面不及MPR,本组仅显示182例,但立体感强,能清晰地显示骨折的部位、程度和范围。结论16层螺旋CTSSD和MPR结合使用对鼻骨骨折的部位、类型、程度和范围具有良好的显示效果,有较高的临床应用价值。
Objective To evaluate the value of 16-slice spiral CT three-dimensional surface shaded display (SSD) and multiplanar reconstruction (MPR) in the treatment of nasal bone fractures. Methods 195 cases of nasal fracture MPR and SSD performance. Results All 195 cases were reconstructed by MPR and SSD. MPR on the nasal bone fracture showed good, 195 cases were clear and can determine the type of fracture; SSD in the display of fracture types less than MPR, the group only shows 182 cases, but the three-dimensional sense of the fracture can clearly show the location, extent and scope . Conclusion The combined use of 16-slice spiral CTSSD and MPR has a good display effect on the site, type, extent and range of nasal bone fractures, and has a high clinical value.
