目的研究T1-vibe MRI成像结合 Argus软件测量膝骨关节炎髌骨软骨体积 的应用价值。方法 选择2013年6月至2014 年6月，于我院治疗膝骨关节炎的患者88 例作为研究对象。以数字法随机将其分为 观察组44例以及对照组44例。观察组患 者使用T1-vibe MRI成像结合Argus软件对 髌骨软骨的体积进行测量，对照组患者使 用T1-vibe MRI成像技术结合常规手工测 量，对比观察两组测量结果，研究其应用 价值。结果 两组在操作过程中，观察组 所需时间明显少于对照组，差异有统计学 意义(P＜0.05)。两组进行测量的可重复 性误差之间进行比较，观察组的误差分别 为6.2%，1.6%，(0.7-2.0)%以及22%，除 个体间差异外，其它均明显低于对照组误 差，差异均有统计学意义(P＜0.05)。两 组髌骨体积测量结果显示，观察组测量体 积和对照组并无较大差异(P＞0.05)，系 统配对误差为-3.8%，两组随机配对误差 为(4.7±2.6)%。结论 使用T1-vibe MRI 成像结合Argus软件测量膝骨关节炎髌骨 软骨体积，大大减少了检测所耗时长，并 且可重复性较高，安全性较好，值得临床 测量使用推荐。

Objective Research the application value of T1-vibe MRI imaging combined with Argus software in measuring the knee osteoarthritis patella cartilage volume. Methods Choose 88 knee osteoarthritis patients who were admitted in our hospital from June 2013 to June 2014, which were devided into two groups with random number table method, every group had 44 patients. We used T1-vibe MRI imaging combined with Argus software to measure the patella cartilage volume of observation group while the control group use T1-vibe MRI imaging combined with manual measurement. Compare the measurement results of two groups and study its application value. Results The examination time of observation group was obviously less than the control group. There's significant difference in the examination time of two groups（P＜0.05）.The comparison of the repeatability error of measurement in two groups indicated that the observation group had less error than the control group, which had significant difference between them. The error of observation group was 6.2%，1.6%，(0.7-2.0)% and 22% respectively. The patella cartilage volume of two groups indicated that there was no significant difference between them（P＞0.05）. System matching error was -3.8%, the random matching error of two groups was（4.7±2.6）%. Conclusion T1-vibe MRI imaging combined with Argus software is used to measure the knee osteoarthritis of patella cartilage volume, which would reduce the test time greatly, it also has higher repeatability and better security. It is worthy of using in clinical measurement.
