What is this test?

This is a contrast-enhanced MRI of the temporomandibular joint, or TMJ. The TMJ connects the lower jaw to the skull and allows the jaw to open, close, and move from side to side.

Why might I need this test?

A TMJ MRI may be ordered to investigate jaw pain, clicking or popping, limited movement, locking, or swelling. It can help assess the joint disc, bones, muscles, and nearby soft tissues.

How is the test performed?

You will lie on a padded table while the MRI machine creates images. Intravenous contrast may be given through a vein in your arm to improve the visibility of certain tissues; the scan itself does not use ionizing radiation.

How do I prepare for the test?

Tell the imaging staff if you are pregnant, have kidney disease, or have had an allergic reaction to MRI contrast. Also report any metal implants, pacemaker, or other devices in your body, and follow the facility's instructions about medications, eating, and drinking.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Abnormal findings may indicate displacement or degeneration of the joint disc, arthritis, inflammation, joint fluid, bone changes, or a mass. Imaging can also identify less common problems such as infection or injury. The results should be interpreted with your symptoms, examination, and other imaging by a qualified clinician.

Short name

TMJ MRI with IV contrast

Frequently asked questions

Does this MRI use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation, although intravenous contrast is sometimes administered.
Why is intravenous contrast used?
Contrast can make inflammation, fluid, and certain tissues easier to see. It is injected through a small IV line, usually in the arm.
What if I am pregnant or allergic to contrast?
Notify the imaging facility before the appointment because these factors may affect whether contrast should be used or whether the examination should proceed. The ordering clinician can review the risks with you.
