Normal variants and pitfalls in magnetic resonance imaging of the ankle and foot

Abstract

Distinction of normal from disease is one of the principal tenets in magnetic resonance imaging (MRI) interpretation of the foot and ankle. Therefore, familiarity with normal anatomic variants and pitfalls in the foot and ankle is crucial for accurate diagnostic analysis of MR images. This article will focus on outlining variants and MRI interpretation pitfalls of the tendons, muscles, bones, ligaments, and other miscellaneous structures of the foot and ankle.
