| 摘 要： | 目的分析多排螺旋CT体积扫描图像三维重建技术在肩关节损伤中的应用.方法 21例肩关节骨折病人接受MSCT检查,对CT二维图像资料经工作站处理,进行多平面重建(MPR)和三维表面遮盖法(SSD)重建,最后进行图像比较分析.结果 MPR可更全面地显示骨折的断面信息, 3D-SSD能立体地显示骨折的范围和方向,对关节脱位的解剖关系显示清楚.结论螺旋CT的2D-MPR和3D-SSD重建作为CT轴位图像的重要补充依据,能更直观和立体地显示肩关节损伤的骨折和脱位情况.

| Abstract: | ObjectiveTo evaluate CT 2D MPR and 3D SSD reconstructions in the diagnosis of shoulder joint injury. MethodsTwenty one patients with shoulder fracture were examined with multi slice CT by using post-process of 2D MPR and 3D SSD reconstruction. ResultsComparing the images of axial CT, 2D MPR and 3D SSD, 2D MPR demonstrated the extent better than axial CT, whereas 3D SSD images showed more exactly extent and direction than the others did. Conclusion2D MPR and 3D SSD images can show the extent and direction of fracture directly. Combining with MPR and SSD images, axial CT image can demonstrate imaging information of shoulder joint injury. |
