The temporomandibular joint (TMJ) is a small joint with complex anatomy and function. Diverse pathologies with very different symptoms can affect the TMJ.

While various imaging techniques such as plain-film radio - graphy and computed tomography can be useful, magnetic resonance imaging’s superior contrast resolution reveals additional structures like the articular disk, making this technique essential for accurate diagnosis and treatment planning.

We analyze the MRI signs of the different pathologies that can affect the TMJ from the structural and functional points of view.
