| 摘 要： | 目的运用16层螺旋CT的3种后处理技术:最大密度投影(MIP)、表面阴影成像(SSD)和容积重组(VR)对肋软骨骨折的显示状况进行评价。探讨肋软骨骨折的最佳CT成像方法。方法搜集经16层螺旋CT常规胸部容积扫描和薄层低对比图像重建41例,所有病例均应用MIP、SSD及VR对重建图像进行后处理,最后由2名CT诊断医师比较MIP、SSD及VR对肋软骨的显示状况。结果3种重组技术均可显示肋软骨。在显示肋软骨形态方面,VR、MIP成像模式优于SSD成像模式;VR成像模式与MIP成像模式差异无统计学意义。结论MIP、VR是显示肋软骨骨折形态的最佳CT成像方式。

| Abstract: | Objective To evaluate the visualization of costicartilage fracture with maximum intensity projection(MIP),surface shaded display(SSD)and volume rendering(VR)techniques using muhislice spiral CT(MSCT),in order to investigate the optimal imaging methods of MSCT in costicartilage fracture.Methods 41 normal cases were performed in volume scan according to conventional chest scan by 16 multi-slice CT and in thin slice low contrast image reconstructions.Then all the source images were processed using MIP,SSD and ... |
