【摘要】 目的　探讨磁共振膝关节斜冠状位扫描对前交叉韧带的显示价值。方法　对 3 0例正常膝关节均行常规横断、斜矢状、冠状扫描 ,扫描序列还包括在斜矢状图像基础上行平行于前交叉韧带FSE序列斜冠状薄层无间隔T2 扫描 ,分析斜冠状、斜矢状及冠状位对正常前交叉韧带的显示情况。结果　正常膝关节于 1幅图片上可清楚显示ACL全程者 ,斜冠状显示率为 10 0 % (3 0 3 0 ) ,斜矢状位显示率为 83 .3 % (2 5 3 0 ) ,而冠状位前交叉韧带呈节段状 ,不能在 1幅图像中显示完整的ACL。结论　斜冠状位可在 1幅图像上完整显示前交叉韧带起止附着区及中间纤维束 ,有利于对前交叉韧带显示及损伤后的评价更多还原

【Abstract】 Objective To investigate the value of obli que coronal MR images in visualization of the anterior cruciafe ligment(ACL).Methods Conventional axial,oblique sagittal and coronal MR images were performed in 30 normal knees.Then oblique coronal T 2-weighted i mages,which was parallel to ACL,based on oblique sagittal T 2 -weighted images ,were acquired.The visualization of ACL on oblique coronal,oblique sagital and coronal T 2-weighted images was analysed.Results The visualization of the whole ACL was 100%(30/30 ) on one image of the oblique coronal T 2-weighted images, 83.3%(25/30) on on e image of the oblique sagaital T 2-weighted image. On the coronal T 2-weighte d images,the ACL appeared as segmental bundle.The whole ACL could not be visua lized on one image of coronal T 2-weighted images.Conclusion The whole ACL can be showed on one image of ob lique coronal T 2-weighted image,which is helpful in evaluation of the injure o f ACL.更多还原
