In the past, MR imaging of the ankle and foot has been performed by scanning both extremities simultaneously to provide a normal side for comparison. More recently, unilateral imaging with small local coils has been favored to maximize spatial resolution through use of small fields of view or large matrices. Such clarity of detail, however, demands a greater knowledge of normal anatomy and anatomic variants. We illustrate the MR appearances of a number of variants involving muscle, tendons, ligaments, and osseous structures of the foot and ankle. Familiarity with these findings is essential to prevent errors in the interpretation of MR images.
过去，踝关节和足部的磁共振成像（MR成像）是通过同时扫描双侧肢体来提供一个正常侧进行对比。最近，人们更倾向于使用小型局部线圈进行单侧成像，以通过使用小视野或大矩阵来最大化空间分辨率。然而，这种清晰的细节需要对正常解剖结构和解剖变异有更深入的了解。我们展示了足部和踝关节的肌肉、肌腱、韧带及骨性结构的一些变异的MR表现。熟悉这些表现对于防止在MR图像解读中出现错误至关重要。
