摘要：目的 分析MRI在肘关节损伤中的应用价值.方法 选择17例经临床或手术证实的肘关节损伤患者,进行T1W/FSE、T2W/FRFSE、STIR序列扫描,回顾性分析、总结其MRI表现.结果 17例均有不同程度骨质损伤,表现为网状、地图状稍长T1信号、等长或稍长T2信号.关节腔积液1例,内侧副韧带损伤5例,撕裂1例,外侧副韧带损伤3例,部分撕裂1例.损伤韧带表现为韧带不同程度增粗,但韧带连续性存在,正常低信号内出现不规则高信号;撕裂表现为韧带明显增粗,呈弥漫性高信号,韧带的连续性部分或完全中断.结论 MRI检查可很好地显示肘关节损伤的各种表现,可作为肘关节损伤检查的重要或首选手段. Abstract： Objective To analyze the MRI findings of elbow joint and assess its diagnosic value. Methods The MRI findings of 17 cases injured elbow joints confirmed clinically and surgically were retrospectively reviewed and evaluated. Results The tibia injury was detected in all, MRI appeared net or piecc-like long T1 and long T2 signal, and joint effusion in 7 cases. The tibial ligament sprains in 5 cases and tears in 1 cases, the fibular collateral ligaments sprains in 3 cases and tearsin 1 cases. MRI of contusive ligaments appeared as irregular hyperitensity in swoilen ligament but their continuity was not disturbed and teared ligament presented as diffusive hyperintensity and total or partial interruption in the injuried ligaments. Conclusions MRI image can accurately demonstrate the various appearances of elbow injury. MRI should be used as a routine or important method in diagnosis of elbow trauma.
