What is this test?

This is a magnetic resonance imaging (MRI) examination of the temporal bones, the skull bones that surround the inner ear. Intravenous contrast is given through a vein to help certain tissues and abnormalities appear more clearly.

Why might I need this test?

It may be used to evaluate unexplained hearing loss, dizziness, balance problems, ringing in the ears, or suspected problems involving the inner ear, nearby nerves, or blood vessels. It may also help assess tumors, inflammation, infection, or congenital abnormalities.

How is the test performed?

You will lie on a table inside an MRI scanner while images of the temporal bones are taken. Contrast material is usually injected into a vein before or during the scan, and the scanner may make loud knocking or clicking sounds.

How do I prepare for the test?

Tell the imaging team about kidney disease, prior contrast reactions, allergies, pregnancy, implanted medical devices, or metal in your body. Follow the facility's instructions, which may include avoiding some medicines or eating and drinking normally unless you are told otherwise.

Frequently asked questions

Does this test use radiation?
No. MRI uses magnetic fields and radiofrequency signals rather than ionizing radiation.
Is intravenous contrast different from the contrast used in some CT scans?
Yes. The contrast used for MRI is a different type of material and may cause warmth, nausea, or a metallic taste, although serious reactions are uncommon.
Will I be able to drive after the test?
Most people can drive afterward, but the facility may advise extra observation if you received sedating medication or had a contrast reaction.
