To determine if angling the coronal plane in magnetic resonance (MR) imaging of the knee increases the conspicuity of the posterolateral structures.
A coronal oblique MR imaging sequence performed parallel to the popliteal tendon proximally was added to our routine study in patient knee examinations. One hundred patients (age range, 12-72 years) underwent MR imaging.
Coronal oblique images depicted the arcuate ligament in 46%, the fabellofibular ligament in 48%, and the fibular origin of the popliteal muscle in 53% of the patients, whereas standard coronal images depicted these in 10%, 34%, and 8% of the patients, respectively. Sagittal oblique images did not adequately depict these structures.
Depiction of the structures in the posterolateral aspect of the knee was optimal on coronal oblique images. We advocate obtaining coronal oblique T2-weighted images in patients with either posterolateral knee pain or suspected injury to the posterolateral ligamentous structures.
确定在膝关节磁共振成像（MR）中使冠状面倾斜是否能提高膝关节后外侧结构的显示清晰度。
在患者膝关节检查的常规研究中增加了一种冠状斜位MR成像序列，该序列在近端与腘肌腱平行。100例患者（年龄范围12 - 72岁）接受了MR成像检查。
冠状斜位图像显示，46%的患者有弓状韧带，48%的患者有豆腓韧带，53%的患者有腘肌的腓骨起点；而标准冠状位图像显示这些结构的患者分别为10%、34%和8%。矢状斜位图像未能充分显示这些结构。
在冠状斜位图像上，膝关节后外侧结构的显示效果最佳。我们主张对有膝关节后外侧疼痛或怀疑后外侧韧带结构损伤的患者进行冠状斜位T2加权成像。
