MR imaging of the wrist and hand—A review of the normal imaging appearance with an illustration of common disorders affecting the wrist and hand

Abstract

This article provides a brief overview of magnetic resonance imaging (MRI) of the wrist and hand for the clinician. A basic review of MRI protocols for the region is followed by discussion of the most common imaging sequences. The appearance of normal anatomy is reviewed with emphasis on structures prone to injury, congenital and developmental abnormalities and normal variants. These are correlated to annotated images. Imaging of distal upper limb pathology and trauma is discussed, with emphasis on the identification of positive findings for the manual physician. Illustrative examples are given with discussion of specific common conditions including carpal coalition, carpal tunnel syndrome, game-keeper's thumb, avascular necrosis, tendinitis and commonly presenting fractures.
