PURPOSE
To explore the consistency of FRACTURE (Fast-field-echo Resembling A CT Using Restricted Echo-spacing) MRI and X-Ray/computerized tomography (CT) in the evaluation of bone injuries in knee and ankle joints.
METHODS
From Nov. 2020 to Jul. 2023, 42 patients with knee joint or ankle joint injuries who underwent FRACTURE MRI examinations were retrospectively collected. 11 patients were examined by both X-Ray and FRACTURE examinations. 31 patients were examined by both CT and FRACTURE examinations. The fracture, osteophyte, and bone destruction of the joints were evaluated by two radiologists using X-Ray/CT and FRACTURE images, respectively. Kappa test was used for consistency analysis.
RESULTS
The evaluation consistency of fracture, osteophyte and bone destruction via X-Ray and FRACTURE images by radiologist 1 were 0.879, 0.867 and 0.847 respectively, and for radiologist 2 were 0.899, 0.930, and 0.879, respectively. The evaluation consistency of fracture, osteophyte and bone destruction via CT and FRACTURE images by radiologist 1 were 0.938, 0.937 and 0.868 respectively, and for radiologist 2 were 0.961, 0.930, and 0.818, respectively.
CONCLUSION
For fracture, osteophyte, and bone destruction of knee and ankle joints. FRACTURE MRI showed a high consistency with X-Ray/CT examinations.
目的
探讨 FRACTURE（Fast-field-echo Resembling A CT Using Restricted Echo-spacing）MRI 在膝关节和踝关节骨损伤评估中的一致性与 X 射线/计算机断层扫描（CT）。
方法
回顾性收集 2020 年 11 月至 2023 年 7 月期间 42 例膝关节或踝关节损伤患者的 FRACTURE MRI 检查资料。其中 11 例患者同时接受 X 射线和 FRACTURE 检查，31 例患者同时接受 CT 和 FRACTURE 检查。两位放射科医生分别使用 X 射线/CT 和 FRACTURE 图像评估关节的骨折、骨赘和骨破坏情况。采用 Kappa 检验进行一致性分析。
结果
放射科医生 1 评估 FRACTURE 与 X 射线图像的骨折、骨赘和骨破坏的一致性分别为 0.879、0.867 和 0.847，放射科医生 2 的一致性分别为 0.899、0.930 和 0.879。放射科医生 1 评估 FRACTURE 与 CT 图像的骨折、骨赘和骨破坏的一致性分别为 0.938、0.937 和 0.868，放射科医生 2 的一致性分别为 0.961、0.930 和 0.818。
结论
对于膝关节和踝关节的骨折、骨赘和骨破坏，FRACTURE MRI 与 X 射线/CT 检查具有高度一致性。
