摘　　要：目的 :探讨正常人寰枢椎相对旋转角度在三维图像上测量的可行性。方法 :10例正常人行头部左、右尽力旋转位颈椎螺旋CT扫描 ,并采用三维影像重建中表面遮盖法 (SSD)重建 ,在二维图像及SSD图像上分别测量寰枢椎的相对旋转角度 ,将两种方法测量结果进行比较。结果 :在二维图像及SSD图像上测量结果无统计学差异(P >0 .0 5 )。结论 :正常人寰枢椎相对旋转角度可以在SSD图像上测量。Objective: To study the feasibility of measurement of the relative rotation degree (RRD) of atlantoaxial vertebrae on three-dimensional images of Computed Tomography. Methods: 10 normal adults were examined by spiral CT while their heads were rotated fully to the right and left. The imaging was reconstructed with three dimensional surface shaded display (SSD) methods, the RRD was measured on two dimensional imaging and SSD, respectively. Results: The data measured and the two methods showed no significant differences with t-test(P>0.05). Conclusion: RRD can be measured on images of SSD.
