MRI of the temporomandibular joints

In contrast to X-rays, magnetic resonance imaging allows the imaging of muscles, joint capsules, tendons and ligaments and thus provides a particularly precise insight into possible malpositions and disorders of the masticatory system. 

Magnetic resonance tomography, or MRT for short, is used when diseases or malpositions of the temporomandibular joints are suspected. The diagnostic examination is painless, takes place without exposure to radiation and allows a three-dimensional view of the temporomandibular joint. Among other things, inflammations, tissue changes as well as displacements of the joint head and other disorders within the masticatory system, such as CMD, can be detected. The examination is useful, for example, in the case of chronic complaints and severe pain that has not shown improvement through other therapeutic options. 

Before the actual treatment, all metallic objects such as watches, hearing aids etc. must be removed. Patients with cardiac pacemakers, insulin pumps or inner ear prostheses are excluded from an MRI examination, as functional disorders may occur. 

Now the patient is placed lying down in a tube in which a special computer produces sectional images of the jaw. It is important that the patient lies still and does not move during the examination. Since an MRI is particularly loud and the tube is very narrow, patients often experience an oppressive feeling. Anxiety patients, or patients with claustrophobia can be given headphones with relaxation music or a sedative on request. 

The examination takes about 15 - 20 minutes.

If an MRI is required for TMJ diagnosis, referral to a radiology center will be made.
