摘要
目的探讨低场MRI对膝关节外伤的诊断价值及MRI表现。方法对经临床或手术证实的48例膝关节外伤患者行低场MRI检查,分析、总结MRI表现。采用0.32T低场MR扫描机,常规应用冠状位和矢状位SE序列、GRE序列及脂肪抑制STIR序列T1WI、T2WI成像。结果骨挫伤及骨折32例;关节囊积液18例;半月板损伤24例;后交叉韧带撕裂伤2例;内侧副韧带撕裂伤9例;外侧副韧带撕裂伤8例;仅3例未见异常。结论低场MRI可以很好显示膝关节损伤后的各种表现,可作为膝关节外伤后检查的首选或重要手段。
Objective To analyze the MRI findings of knee joint injury and assess the diagnostic value of the low field intensity MR.Methods The MR findings of 48 injured knee joints confirmed clinically or surgically were retrospectively reviewed and evaluated.Sagittal and coronal scanning with SE T1W sequences were used at 0.32T MR scanner.Results Bony contusion and fracture was 32 cases,joint effusion was 18 cases,meniscal tear was 24 cases,posterior cruciate ligament sprang was 2 cases,the tibial collateral ligament sprains in 9 cases,the fibular collateral ligament sprains in 8 cases,but only 3 cases no abnormalities were found.Conclusion The low field intensity MR can accurately demonstrate the appearances of knee injury.It should be used as an important or routine method in diagnosis of knee injury.
