摘  要:目的评价MRI对运动性软组织损伤的诊断价值和临床意义。方法58例不同部位运动性损伤患者接受MR检查,但X线平片未显示骨折。MR检查时间为外伤后1~14d,常规包括T1WI,T2WI以及T2WI脂肪抑制序列和短时间反转恢复序列(STIR)。观察软组织和骨损伤的MR表现。结果58例中发现髋肌损伤8例,胴绳肌损伤6例,股四头肌损伤5例,小腿三头肌损伤15例,胫侧副韧带损伤6例,前交叉韧带损伤5例,后交叉韧带损伤4例,髌韧带损伤3例,跟腱损伤4例,腓短肌键损伤2例。MR表现分为3度,Ⅰ度为牵拉伤,共31例,Ⅱ度为部分撕裂,共19例,Ⅲ度为完全断裂,共8例。损伤肌肉肌腱邻近的骨髓水肿23例,主要为Ⅱ度及Ⅲ度损伤的病例,其中1例可见骨骺骨折,X线片显示可疑。结论肌肉肌腱韧带损伤具有特征性的MR表现。Objective To evaluate the ability and clinical significance of MRI in diagnosis of soft tissue trauma. Methods 58 patients with a history of trauma in different parts of body and no evidence of fractures on X-ray films underwent MR imaging examinations after trauma 1-14 d. MR imaging sequences included T1WI,T2WI and T2 fat suppression sequences and short inversion recovery sequence(STIR). MR imaging features of soft tissue and bone trauma were analysed. Results Soft tissue injury in 58 cases included hip musculus in 8, hamstring musculus in 6, musculus quadriceps in 5, musculus triceps in 15, tibial lateral ligaments in 6, anterior cruciate ligaments in 5,posterior cruciate ligaments in 4, palellar ligaments in 3,achilles tendon in 4 and fibula short musculus in 2. MRI findings of soft tissue could be classified as three degrees :Ⅰ as traction injury in 31 cases,Ⅱ as tearing partially in 19 cases and Ⅲ as completely disrupted in 8 cases. In the majority of cases in Ⅱ and Ⅲ, marrow near soft tissue trauma could be seen in 23 cases. 1 case had epiphysis fracture. Conclusion MRI is of important value in diagnosing soft tissue trauma.
