16层螺旋CT在颅骨骨折病人中的临床应用

Clinical application of 16-slice Spiral CT in Skull Fracture

目的:探讨16层螺旋CT在颅骨骨折病人中的诊断价值。方法:将所检病人按照设定好的方案扫描,待重建结束后,将需要的重建图像导入配备的工作站。根据头颅外伤的部位,选用不同的处理方式和相应软件进行三维重建。结果:对这100例患者回顾性分析,通过层厚为8 mm的横断面图像诊断,只有89例发现颅骨骨折。在对这些患者的重建薄层图像的连续观察后,颅骨骨折人数增至93例。而将重建薄层图像经工作站的相应软件进行3D处理后,100例患者的颅骨骨折均被发现。结论:头颅外伤时颅骨骨折的诊断,仅靠原始的厚层图像是不可靠的。应结合不同重建参数获得的薄层图像连续观察,尤其是通过功能强大的工作站处理后的优质三维图像综合诊断,这样才能使确诊率大为提高。

Objective： To evaluate the value of 16- slice Spiral CT in diagnosis of skull fracture. Methods： 100 patients suspected skull trauma undervent head multislice spiral CT （MSCT） examinations. All original images were transferred to workstation and post- processed. Results： Among 100 skull trauma patients, skull fractures were fond in 89 cases with the routine 8mm slice thickness cross- sectional imaging.After careful observation by thinner slice thickness cross- sectional image, the number of fracture were 93 cases. All 100 patients were found fracture by images of the three - dimensional reconstruction. Conclusion： The diagnosis of skull trauma by routine original images is not enough. The application of thin slice thickness images and the three - dimensional reconstruction is necessary to improve the diagnosis rate.
