摘　　要：目的：探讨3．0TMRI在肘关节脱位后内侧副韧带前束损伤中的应用。方法回顾性分析20例肘关节脱位患者内侧副韧带前束损伤的M RI征象；常规行冠状位、矢状位、轴位及薄层斜冠状位扫描，扫描序列包括SET1WI、T2加权预饱和脂肪抑制序列（T2 WI‐FS）。结果20例患者中，内侧副韧带前束均有不同程度损伤，其中轻度损伤8例，部分撕裂5例，完全断裂7例；另外11例伴外侧副韧带损伤，5例伴环状韧带损伤，9例伴屈／伸肌总腱损伤，7例伴发骨折。结论3．0TMRI能准确诊断肘关节脱位后内侧副韧带前束损伤，并能明确其损伤程度；对肘关节脱位患者宜常规行M RI检查。Objective To apply 3 .0T MRI in diagnosing injuries of anterior bundle of medial collateral ligament after elbow dislo‐cation .Methods The MRI features of the injuries of medial collateral ligament anterior bundle were analyzed retrospectively in 20 patients with elbow dislocation .The coronal ,sagittal ,axial and lamina oblique coronal were scanned routinely with SE T1WI ,T2WI‐FS sequences .Results Varying degrees of anterior bundle injuries of medial collateral ligament were observed in all the 20 patients ,in‐cluding the mild injury（n=8） ,part avnlsion（n=5） ,completely rupture（n=7） .Furthermore ,concomitant injuries including lateral collateral ligament（n=11） ,ringlike ligament（n=5） ,flex/stretch muscle tendon（n=9） ,and the fracture（n=7） were also observed . Conclusion The injuries of medial collateral ligament anterior bundle after elbow dislocation could be diagnosed accurately with 3 .0T MRI and the degree of injuries could also be defined on image .The 3 .0T MRI could be recommended as regular examination to pa‐tients with elbow dislocation .
