摘要(Abstract)：

[目的]探讨基于CT图像使用Mimics软件量化颈椎后纵韧带骨化(OPLL)容积方法的可行性,并将测量结果与传统X线测量法进行比较。[方法]选取于本院2012年2月～2015年12月在门诊接受非手术治疗的34例颈椎OPLL患者,所有患者均至少先后两次同时接受颈椎侧位X线片和CT平扫检查。由3名高年资骨科专科护师在1名脊柱外科医师的指导下分别于两次检查后使用X线法和Mimics软件法对骨化物的容积进行测量,每次测量均重复1次,对测量结果进行可信度和可重复性分析。[结果]X线片法组中共有5例患者因摄片质量问题而导致测量失败,Mimics软件法组均顺利完成测量。两次测量平均间隔14.3个月。两种测量方法均提示OPLL发生进展,X线法测得的骨化物纵向长度平均进展率为4.52%,Mimics?软件法组骨化物容积的平均进展率为5.82%。X线法的可重复性为较好～极佳水平(ICC为0.810～0.922),可信度均为较好水平(ICC为0.786和0.824);Mimics软件法的可重复性和信度均为极佳水平(ICC≥0.9)。[结论]本研究结果表明,基于CT图像,使用Mimics软件能够更为精确地测量OPLL的容积。
