螺旋CT三维重建及切割软件在诊断颌面部骨折中的应用

目的探讨螺旋CT三维重建及切割软件在诊断颌面部骨折中的应用价值。方法29例颌面部骨折病例,先经螺旋CT扫描,后在工作站上进行三维重建和切割,显示骨折,分析总结二、三维及切割软件在显示骨折方面的效果。结果三维影像在显示浅部颌面部骨折位置,范围,骨碎片移位方面优于二维影像,但在显示深部结构方面不及二维影像;结合使用切割软件可扩大三维重建的应用范围,可同样清楚显示深部的三维结构。结论三维影像可清楚显示颌面部的空间解剖关系,切割软件能扩大三维软件的应用范围,可显示清楚深部结构的三维关系,有重要的临床应用价值。

The Diagnostic Value of Using Three-dimensional Reconstruction and Incising Software in Maxillofacial Fracture

Objective To evaluate the clinical value of using three-dimensional reconstruction and incising software in facial fracture. Methods Twenty-nine patients of facial fracture were examined with spiral CT first and then the images were taken with three-dimensional reconstruction and incising software on work-station. 2D images, 3D images and incising images were evaluated. Results BZ 3D images were superior to 2D images in demonstrating the space relationship of facial fractures, such as the fracture location, range, fragments displacement. However 2D images were better in illustrating deep structure; The 3D images could illustrate deep structure as well as 2D images when combined with incising software. Conclusion 3D images can provide information of space relationship in assessing facial fracture. The range can be extended combining with the incising software, and do better for illustrating deep struction.
