What is this test?

This is a magnetic resonance imaging (MRI) scan of the brain focused on the temporal regions, which help with hearing, memory, language, and other functions. It is performed without injected contrast material.

Why might I need this test?

A temporal brain MRI may be ordered to evaluate symptoms such as seizures, hearing changes, memory problems, or other neurological concerns. It can also help identify structural abnormalities, including tumors, inflammation, injury, or changes in brain tissue.

How is the test performed?

You will lie on a table inside an MRI scanner while images of the brain are taken. The machine uses magnetic fields and radio waves, so it does not use ionizing radiation. The scan usually takes 20 to 60 minutes, depending on the examination.

How do I prepare for the test?

Follow the imaging center's instructions and tell the staff about any implanted devices, allergies, pregnancy, or metal in your body. You may be asked to remove jewelry, glasses, hearing aids, and other metal-containing items before the scan.

Frequently asked questions

Does this test use radiation?
No. MRI uses magnetic fields and radio waves rather than ionizing radiation, so it does not expose you to X-ray radiation.
Why is it called a temporal brain MRI?
The scan focuses on the temporal lobes on the sides of the brain, areas involved in functions such as hearing, memory, and language.
Can I undergo this MRI with metal implants or other medical devices?
Some implants are safe, while others may restrict MRI. Tell the imaging staff about every implanted or portable medical device so they can confirm whether the scan is appropriate.
