摘　　要：目的探讨MRI在膝关节外伤中的诊断价值。方法对69例患者70个外伤膝关节进行T1W/SE、T2W/TSE、STIR序列扫描,并与X线及CT结果对比分析。结果70个膝关节MRI诊断25例骨折,35例骨髓水肿,31例半月板损伤,40例韧带损伤,46例关节积液。X线和CT诊断17例骨折,3例关节积液。结论MRI能够清楚地显示膝关节损伤的部位、性质和程度,其准确性和临床应用价值明显优于传统X线和CT,有利于患者及时有效的治疗。Objective To evaluate the diagnostic value of MRI in the knee joint trauma. Methods MR images of 70 cases of traumatic knee joint were obtained using T1W/SE, T2W/TSE, STIR and contrastively analyzed with the X-ray and CT findings. Results 25 cases of fracture, 35 of bone marrow edema, 31 of meniscus trauma, 40 of ligament trauma and 46 of hydrarthrosis were diagnosed by MRI, whilst 17 cases of fracture and 3 of hydrarthrosis were diagnosed by X-ray and CT. Conclusion Being able to manifest the location, kind and degree of trauma, MRI has better accuracy and clinic value than traditional X-ray examination and CT in the diagnosis of knee acute injury.
