Magnetic Resonance Imaging of the Foot and Ankle

Abstract

Magnetic resonance imaging (MRI) can provide detailed information regarding the anatomy of the foot and ankle in health and disease. The physics and interpretation of MRI are complicated, and here we provide helpful concise tenets to facilitate understanding of the fundamental principles of MRI physics and interpretation in clinical routine. The advantages and disadvantages of MRI versus computed tomography (CT) for the musculoskeletal system are briefly discussed. Furthermore, the basic MRI appearance of normal and pathologic musculoskeletal tissue is demonstrated and a tailored MRI protocol for the foot and ankle region is provided. The main emphasis is on the anatomical detail and common pathology of the respective areas (ankle, hindfoot, midfoot, and forefoot).
