Introduction

Magnetic resonance imaging represents a relevant way to diagnostically assess the wrist with high-resolution, multiplanar imaging without employing ionizing radiation. It influences clinical and surgical diagnosis and management of wrist pathologies.^[1] This article will discuss typical indications for advanced imaging of the wrist, including post-traumatic lesions, avascular necrosis, chondral injuries and arthritis, tendon pathologies and internal derangements of ligaments and the triangular fibrocartilage complex (TFCC).
