Magnetic resonance imaging of temporomandibular joint disc abnormalities: A pictorial essay

Abstract

Internal derangement is the most common pathological condition affecting the temporomandibular joint (TMJ). Magnetic resonance imaging (MRI) of TMJ is principally directed toward assessment of the soft-tissue abnormalities in terms of internal derangement. This pedagogical article describes anatomy and biomechanics and provides a pictorial overview of the MRI findings of the disc abnormalities of TMJ.
