摘　　要：目的探寻膝关节交叉韧带的完整显示最佳MR成像方法。方法健康成人自愿者膝关节30例,分别进行膝关节伸直位、微曲位(17°)和屈曲位(45°)的快速自旋回波序列垂直矢状位和斜矢状位的MR扫描,观察不同位置、不同角度交叉韧带的显示效果及MRI表现。结果30例膝关节前交叉韧带(ACL)在伸直位垂直、斜矢状面完整显示率分别为63.3%、70.0%;微曲位垂直、斜矢状面上完整显示率分别为93.3%、96.7%;屈曲位垂直、斜矢状面上完整显示率分别为96.7%、100.0%。后交叉韧带(PCL)在不同位置、不同角度断面完整显示率均为100%。结论MRI成像中交叉韧带在屈曲位斜矢状面显示最佳。Objective To find out the best method of MR imaging in showing the cruciate ligament completely . Methods 30 eases of adult knee joints were scanned by MR with the spin echo at vertical sagital surface and inclined sagital surface in extending position,slightly bending position（ 17°） and bending position （45°） ,the MR manifestations and showing effect of cruciate ligaments in different position and different angle in workstation. Results The complete showing rate of anterior cruciate ligament （ ACL ） in the vertical and inclined sagittal surface of extending position was 63.3% and 70.0% ; in slightly bending position was 93.3% and 96.7% and in bending position was 96.7% and 100.0% respectively. Conclusion Cruciate ligament is best display in sagittal bending position on MRI.
