MR imaging is the imaging technique of choice for evaluating ankle tendons and ligaments. Although reformation of three-dimensional Fourier transform (3DFT) gradient-recalled echo (GRE) MR images on an independent console has been evaluated in other joints, little attention has been given to use of this technique for evaluation of the ankle. In this essay, we illustrate the spectrum of normal appearances of the posterior tibial tendon (PTT), flexor digitorum longus tendon, flexor hallucis longus tendon, and plantar calcaneonavicular ligament (PCNL) on 3DFT GRE images. Also, we describe the advantages of evaluating these structures with 3DFT GRE vs spin-echo (SE) MR images, demonstrate the spectrum of abnormal findings seen in these structures on 3DFT GRE MR images in a large clinical series, and show the relationship of the accessory navicular bone to PTT abnormalities.
磁共振成像（MR）是评估踝关节肌腱和韧带的首选成像技术。尽管在独立控制台对三维傅里叶变换（3DFT）梯度回波（GRE）MR图像进行重组已在其他关节中得到评估，但该技术用于踝关节评估的情况却很少受到关注。在本文中，我们展示了三维傅里叶变换梯度回波图像上胫后肌腱（PTT）、趾长屈肌腱、拇长屈肌腱和跟舟跖侧韧带（PCNL）的正常表现谱。此外，我们描述了与自旋回波（SE）MR图像相比，利用三维傅里叶变换梯度回波评估这些结构的优势，在一个大型临床系列中展示了三维傅里叶变换梯度回波MR图像上这些结构中所见异常表现谱，并显示了副舟骨与胫后肌腱异常的关系。
