MRI扫描技术在踝关节损伤的应用价值

目的探讨MR I扫描技术在踝关节损伤的应用价值。方法搜集33个损伤后踝关节,在自然体位下应用柔性线圈和头部线圈,矢状位采用双回波快速自旋序列(pd t2-tse),快速小角度单次激发加脂肪抑制(t2-fl2d fs)及短时反转恢复(t2-tirm)3种序列,冠状位和横断位采用多回波(m e-2d)序列检查。结果本组33个踝关节中有阳性发现的关节为25个,检查阳性率75.8%。结论踝关节的矢状位扫描以pd t2-tse和t2-fl2d fs为常规序列,t2-tirm为辅助序列,冠状位或横断位以m e-2d为常规系列,即可满足踝关节损伤的诊断要求。

Applied Value of MRI Scanning Technology in the Ankle Injury

Objective To discuss the applied value of MRI scanning technology in the ankle injury.Methods 33 cases of ankle injury were examined by MRI using flexible loop and head loop,the sequences were pd t_2-tse,t_2-fl2d fs,t_2trim(sagittal section) and me-2d(coronal section).Results The positive features in 25 of 33 cases were found on MRI,the positive rate was 75.8%.Conclusion In MR examination of the ankle's injury,the sagittal pd t_2-tse and t_2-fl2d fs are the routine sequences,the sagittal t_2-tirm sequence is the accessorial sequence,in the coronal or transverse scanning,the me-2d is the routine sequence,that can be satisfactory for clinical diagnosis.
