摘要: 目的: 探讨不同磁共振扫描方法对膝关节前交叉韧带(ACL)的显示价值。方法: 对43例正常膝关节在常规横轴位、冠状、斜矢状扫描及在斜矢状图像基础上行平行于前交叉韧带的斜冠状薄层无间隔扫描、斜矢状薄层无间隔扫描。分析斜冠状、斜矢状及斜矢状薄扫对正常前交叉韧带的显示情况。结果: 斜冠状与斜矢状位薄扫可于一幅图片上清楚显示正常膝关节ACL全程,显示率均为100%(43/43),斜矢状位在一幅图片的显示率为83.7%(36/43)。结论: 斜冠状位与斜矢状薄扫可在一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。

    Abstract: Objective： To investigate the value of thin scan of Oblique Coronal and oblique sagital MR Images in visualization of the anterior cruciate ligment( ACL). Methods: Conventional axial, coronal and oblique sagital MR images were performed in 43 normal knees. Then thin scan of oblique coronal and oblique sagital images, which was parallel to ACL, based on conventional oblique sagittal images, were acquired. The visualization of ACL on thin scan of oblique coronal and oblique sagital, conventional oblique sagital images were analysed. Result: The visualization of the whole ACL was 100%(43/43) on one image of the thin scan of oblique coronal and oblique sagital ......
