中文摘要:
      目的 比较三维CT(3D-CT)和三维MRI(3D-MRI)诊断肩关节肩盂骨质缺损(GBL)的价值。方法 对50例肩关节不稳定患者行3D-CT和3D-MR扫描,比较分析两者测得的关节盂面积、GBL面积及GBL程度;术中采用数字卡钳测量所有患者GBL程度,以之作为金标准,对3D-CT和3D-MRI结果进行一致性检验,判断其诊断性能。结果 3D-CT测量的最佳拟合圆表面积大于3D-MRI,但差异无统计学意义(P>0.05)。3D-CT和3D-MRI测量GBL表面积和GBL程度差异均无统计学意义(P均>0.05)。线性回归分析结果显示,两者测得的最佳拟合圆表面积的回归系数为1.06(R2=0.78);而GBL表面积之间的回归系数为1.05(R2=0.88)。3D-CT和3D-MRI测得的GBL程度与术中测量结果的一致性较好(Kappa=0.82、0.88,P均<0.05)。结论 3D-MRI和3D-CT诊断肩关节GBL效果相当;3D-MRI具有替代3D-CT于术前更全面、无辐射评估SI患者GBL情况的潜在可能。
英文摘要:
      Objective To compare the value of three dimensional CT (3D-CT) and three-dimensional MRI (3D-MRI) in diagnosing shoulder glenoid bone loss (GBL). Methods Totally 50 patients with shoulder instability (SI) underwent 3D-CT and 3D-MR examinations. Glenoid surface area, GBL surface area and degree of GBL measured with 3D-CT and 3D-MRI were comparatively analyzed. Digital calipers was used to measure GBL of all patients during operation, and the data were analyzed with Kappa test to observe diagnostic performance of 3D-CT and 3D-MRI. Results The best fitting circle surface area with 3D-CT was larger than that with 3D-MRI, but there was no significant difference (P>0.05). There was no significant difference of GBL surface area nor degree of GBL acquired using two methods (both P>0.05). According to linear regression analysis, the regression coefficient of the best fitting circular surface area was 1.06 (R2=0.78) between 3D-CT and 3D-MRI, of GBL surface area was 1.05 (R2=0.88). GBL degree measured with 3D-CT and 3D-MRI was in good agreement with intraoperative measurement results (Kappa=0.82, P<0.05; Kappa=0.88, P<0.05). Conclusion 3D-CT and 3D-MRI have the same value in diagnosis of shoulder GBL. 3D-MRI has the potential to take place of 3D-CT for providing full and non-radiative pre-operative evaluation of GBL in SI patients.
