Fifty-three ankles of 29 normal volunteers were examined with Magnetic Resonance Imaging (MRI) to improve the anatomical MR knowledge of tibiotalar and subtalar joints. The aim of our study was therefore to assess the visibility of articular cartilages, tendons and ligaments of the ankle and to define the best scan plane for their visualization. MR studies were performed with SE T1-weighted sequences on the sagittal, coronal and axial planes. The visibility of articular cartilages was 70.8% for the tibiotalar joint and 56.3% for the subtalar joint. All ankle tendons and four of the eight ankle ligaments considered in our study were assessed, at least on one of the sagittal, coronal or axial planes, with over 70% visibility. The deltoid ligament was detected in 95% of the cases on coronal images, the anterior and the posterior talofibular ligaments were seen respectively in 82% and in 75% of the cases on axial images, while the interosseous ligament was detected in 87.5% of the cases on sagittal images. Our study assessed both the capabilities and the limitations of MRI in the detection of anatomical structures of the tibiotalar and subtalar joints and defined the best scan plane for their visualization.
对29名正常志愿者的53个踝关节进行了磁共振成像（MRI）检查，以增进对胫距关节和距下关节的解剖学MRI知识。因此，我们研究的目的是评估踝关节软骨、肌腱和韧带的可视性，并确定用于观察它们的最佳扫描平面。采用SE T1加权序列在矢状面、冠状面和轴位面上进行MR研究。胫距关节软骨的可视性为70.8%，距下关节软骨的可视性为56.3%。我们研究中考虑的所有踝关节肌腱和八条踝关节韧带中的四条，至少在矢状面、冠状面或轴位面上的一个平面上被评估，可视性超过70%。在冠状位图像上，95%的病例检测到三角韧带；在轴位图像上，分别有82%和75%的病例看到距腓前韧带和距腓后韧带；而在矢状位图像上，有87.5%的病例检测到骨间韧带。我们的研究评估了MRI在检测胫距关节和距下关节解剖结构方面的能力和局限性，并确定了用于观察它们的最佳扫描平面。
