目的研究螺旋CT二维重建及三 维重建在骨关节病变中的诊断价值。方 法 回顾性分析从2013年8月-2015年4月在 我科收治的骨关节病变患者98例。对患者 先行X线平片进行检查(对照组)，之后实 施螺旋CT二维重建与三维重建检查(观察 组)，对比两组诊断价值。结果 观察组股 骨头坏死41.84%、半月板撕裂伤24.49%、 骨性关节炎32.65%、关节病变18.37%的检 出率均分别显著高于对照组的25.51%、 13.27%、18.37%、7.14%，差异均有统计 学意义(均P＜0.05)。观察组对骨关节病 变检查漏诊率2.04%、误诊率0.00%，显著 低于对照组的9.18%、5.10%，差异均有统 计学意义(均P＜0.05)。观察组检查骨关 节病变的敏感度86.73%及特异性89.80%均 分别显著高于对照组的68.37%、76.53%， 差异均有统计学意义(均P＜0.05)。观察 组单病灶检出率45.92%、多病灶检出率 52.04%均分别明显高于对照组的30.61%、 34.69%，差异均有统计学意义(均P ＜0.05)。结论 螺旋CT二维重建及三维重 建技术具有高敏感度、特异性特点，运用 于骨关节病变中能明显提高病变检出率， 为临床提供精准诊断信息，安全性高，值 得推荐。

Objective To study diagnosis value contrast of Spiral CT two-dimensional reconstruction and three-dimensional reconstruction for the bone joint disease. Methods Retrospective analysis from August 2013 to April 2015, 98 cases of bone joint disease patients admitted in our department. Inspection on patients was first with X-ray plain film (control group), then with the spiral CT two-dimensional reconstruction and threedimensional reconstruction (observation group), compared with the diagnosis value. Results The observation group of femoral head necrosis 41.84%, meniscus tear24.49%, osteoarthritis 32.65%, joint disease 18.37% detection rate was significantly higher than the control group of 25.51%, 13.27%, 18.37%, 7.14%, had statistically significant differences (all P<0.05). Observation group for joint disease's rate of leakage diagnosis 2.04%, misdiagnosis 0.00%, was significantly lower than the control group were 9.18%, 5.10%, which were statistically significant differences (all P<0.05). Observation group check especially the sensitivity of 86.73% and specificity 89.80% was significantly higher than the control group 68.37%, and 68.37%, which were statistically significant differences (all P<0.05). Observation group's single lesion detection rate 45.92%, lesion detection rate 52.04% was significantly higher than the control group of 30.61% and 30.61%, which were statistically significant differences (all P<0.05). Conclusion Spiral CT two-dimensional reconstruction and three-dimensional reconstruction technique has the characteristics of sense of high sensitivity, specificity, applied to joint pathological changes can be obviously improved lesion detection rate, provide accurate diagnostic information for clinical. It has high security, is worth to recommend.
