What does an MRI of the TMJ show?
MRI could also detect the early signs of TMJ dysfunction, like thickening of anterior or posterior band, rupture of retrodiscal tissue, changes in shape of the disc, joint effusion . Images can be obtained in all planes (sagittal, axial, coronal).
Can you see the brain in a TMJ MRI?
Intracranial findings. Intracranial cavity is partially imaged during a standard MRI examination of the TMJ. This is usually demonstrated in both scout images and cross-sectional sagittal oblique dedicated slices of the TMJ.
Do you need an MRI to diagnose TMJ?
Temporomandibular joint (TMJ) abnormalities cannot be reliably assessed by a clinical examination. Magnetic resonance imaging (MRI) may depict joint abnormalities not seen with any other imaging method and thus is the best method to make a diagnostic assessment of the TMJ status.
How long does a TMJ MRI take?
➢ You will need to open and closed you mouth for different parts of the exam. ➢ Your scan will take approximately 45-60 minutes. ➢ There are no restrictions placed upon you. You may eat or drive as normal, although if you took relaxation medication, you will need someone to drive you home.

Does TMJ affect your brain?
Patients with temporomandibular disorder (TMD) perform poorly in neuropsychological tests of cognitive function. These deficits might be related to dysfunction in brain networks that support pain and cognition, due to the impact of chronic pain and its related emotional processes on cognitive ability.
What is considered severe TMJ?
Internal TMJ derangement – Internal derangement is the most serious category of TMJ disorders. Trauma or a displaced jaw, among other causes, can precipitate it.
Can I cough during an MRI?
If you have a cough or cold, consider taking a cough suppressant or decongestant prior to you visit.
