摘要
目的:探讨颞骨的多层螺旋CT检查技术及临床应用价值。方法:对42例正常及56例异常颞骨行HRCT扫描,把扫描获得的容积数据行三维重建,包括多方位重组技术(MPR)、最大及最小密度投影法(MIP、MinIP)、仿真内镜法(VE)、容积再现法(VR)、表面阴影成像法(SSD)。结果:各种三维重建技术都可以从不同方面对颞骨结构进行显示。结论:HRCT和MPR技术是颞骨多螺旋扫描中最常用、最重要的检查方法,其他重建方式是对它们多层次、多角度的重要补充。
Objective： To explore the temporal bone of the multi-slice spiral CT examination techniques and clinical value. Methods： 42 cases of normal and 56 cases of abnormal temporal bone were performed HRCT scan, and the volume data obtained by scan were performed three-dimensional reconstruction, including the multi-directional reformation （MPR）, the largest and minimum intensity projection （MIP, MinlP）, virtual endoscopy law （VE）, volume rendering （VR）, shaded surface imaging（SSD）. Results： The various three-dimensional reconstruction techniques could show the structure of the temporal bone from different aspects. Conclusion： HRCT and MPR technology are the most commonly used and most important examination techniques, and other redevelopments are the multi-level perspective of an important supplement.
