Abstract：
:Normal anatomic variants may erroneously be interpreted as pathologic conditions on MR imaging of the ankle and foot. Therefore, sufficient knowledge of the normal anatomy and its variations is crucial for accurate diagnostic analysis of such images. This article will focus on outlining variants and MR imaging interpretation pitfalls of the tendons, ligaments, muscles, bones, and other miscellaneous structures of the foot and ankle.
