Magnetic resonance imaging of the temporomandibular joint

This article aims to provide a brief overview of magnetic resonance imaging (MRI) of the temporomandibular joint (TMJ) for the clinician. A basic review of previous MRI protocols for the region is followed by discussion of the most common imaging sequences. The appearance of normal TMJ anatomy is reviewed with emphasis on structures prone to injury; congenital and developmental abnormalities; normal variants and pathology. These are correlated to annotated images. Imaging of TMJ pathology and trauma is then discussed with emphasis on the identification of key elements for the manual physician. Illustrative examples are given with discussion of specific common conditions.
