The normal anatomy of the lateral ankle and subtalar ligaments seen at magnetic resonance (MR) imaging was studied in four cadaver ankles. Sixteen ankles of 11 healthy volunteers were imaged with four different MR imaging protocols to optimize technique. The anterior talofibular ligament was identified in 100% of the ankles of the volunteers in the axial plane, the calcaneofibular ligament in 81% of the ankles in the coronal plane, the cervical ligament in 69% of the ankles in the coronal plane and in 88% of the ankles in the sagittal plane, and the talocalcaneal ligament in 56% of the ankles in the coronal plane and in 62% of the ankles in the sagittal plane. It is concluded that thin-section (1-3-mm) MR imaging techniques, especially the one in which data are acquired with three-dimensional Fourier transform, are best for visualization of the ligaments. These techniques may play a role in the evaluation of patients with chronic ankle pain and instability.
对四个尸体踝关节进行了磁共振成像（MR）检查，研究了外侧踝关节和距下关节韧带的正常解剖结构。采用四种不同的MR成像方案对11名健康志愿者的16个踝关节进行成像，以优化成像技术。在轴向平面上，100%的志愿者踝关节中可识别出距腓前韧带；在冠状平面上，81%的踝关节中可识别出跟腓韧带；在冠状平面上，69%的踝关节中可识别出颈韧带，在矢状平面上，88%的踝关节中可识别出颈韧带；在冠状平面上，56%的踝关节中可识别出距跟韧带，在矢状平面上，62%的踝关节中可识别出距跟韧带。结论是，薄层（1 - 3毫米）MR成像技术，尤其是采用三维傅里叶变换采集数据的技术，最有利于韧带的可视化。这些技术可能在慢性踝关节疼痛和不稳定患者的评估中发挥作用。
