| 摘 要： | 探讨颅底MSCT三维重建图像效果及主要孔的正常值,采用多层螺旋CT(MSCT),对200名正常成人(男100名,女100名)进行颅脑扫描,利用电子计算机三维重建程序立体地显示颅底外面的卵圆孔、棘孔、颈动脉管外口、破裂孔、茎乳孔、枕骨大孔,并观察其形态和测出其内径及其性差。

| Abstract: | Objective:The purpose of this research is to determine the results of three-dimensional reconstructed skull imaging using the multi-slice spiral computed tomography(MSCT) technique and to assess the normal values of the main canals and foramina in a skull base.Methods: This study used the multi-slice spiral computed tomography(MSCT) technique for brain scans of 200 normal adults(100 male and 100 female).A three-dimensional reconstruction computer software program was implemented to assess the three-dimensional reconstruction of the skull base,which provided a 3-D display of the foramen ovale,foramen spinosum,outside foramen of the carotid canal,foramen lacerum,foramen stylo-mastoideum and the foramen magnum.The program measured functions the average inside diameters of the foramina and also observed foramina shape and sex differences. |
