蝶腭孔CT三维成像的临床研究

目的：应用多层螺旋CT对鼻腔外侧壁即蝶腭孔进行重建观察，重建立体图像资料的数据与解剖标本数据进行对照，以验证三维成像测量数据的可靠性。方法：选用5具(10侧)固定后的成人尸颅进行位置、形状、大小及毗邻关系的观察与有关数据的测量。结果：多层螺旋CT成像的速度快．图像清晰，表面遮盖差异显示容积技术对鼻腔外侧壁即蝶腭孔的成像．表面结构清晰。多层螺旋CT成像的测量数据与解剖测量的数据无统计学意义．可直接指导临床。结论：多层螺旋CT三维立体成像可以帮助手术定位。

The clinical study of multi-slice helical CT three-dimensional reconstruction in the sphenopalatine foramen

Objective:Used multi-slice helical CT to observe the reconstruction of the surface structure of nasal lateral wall "sphenopalatine foramen" and compared with anatomical specimens to verify the dependability of 3D data.Method:The position, shape,size and their correlational data of sphenopalatine foramen of 5 cadaver heads (10 sides) in adults fixed with formalin were dissected and measured.Result:Multi-slice helical CT has more rapid speed of 3D reconstruction and clearer imaging.The technique of Shade surface display and Volume rendering can give very clear structure of nasal lateral wall "sphenpalatine foramen".The 3D data makes no statistic difference with anatomical measurement. The 3D data can instruct the clinic directly.Conclusion:Multi-slice helical CT three-dimensional reconstruction can be used to orientation of surgery.
