目的用计算机辅助软件Mimics测量数字影像学资料的Cobb角,将其同传统X线片测量方法比较,探索将其用于临床测量的可能性及其优劣势.方法随机选择20例脊柱侧凸患者X线胶片,扫描后,由两名经验丰富的医生用Mimics进行Cobb角测量,并同样由这两名医生测量X线胶片Cobb角,各测量两次(之间间隔1周),对所得Cobb角和两次测量之间的差值进行统计分析.结果 Mimics测量和传统x线胶片测量的Cobb角之间有很好的相关性,重复测量方差分析并无统计学差异(r=0.986,P＞0.10).Mimics和传统x线胶片方法的重复测量差值有显著差异(Wilcoxon 检验,Z=-2.576,P＜0.05),Mimics较传统测量更为精确.不同测量者用Mimics测量Cobb角时,不影响测量的精度.结论 Mimics可用于数字影像学资料Cobb角的测量,其精度优于传统X线胶片测量.

Objective To assess Mimics as a new measurement method in Cobb angle in a comparison with traditional measurement and try to explore the advantages and disadvantages of the new method. Methods Twenty X-ray plates of scoliosis were chosen randomly. Two experienced physicians measured the Cobb angles via Mimics and traditional methods twice with an interval of 1 week.And statistical analyses of Cobb angle and difference between two measurements were carried out. Results The overall correlation was 0. 986 for Mimics and traditional measurements. ANOVA demonstrated no significant difference between these two methods. A significant difference existed between the first and second values of Cobb angle in Mimics and traditional measurements. However the absolute difference was small. Conclusion Mimics can be a new method for measuring the digital radiographs. And its precision is superior to that of the traditional measurement.
