What Happens During an MRI?

Getting an MRI for the first time can feel intimidating when you’re unsure what to expect. The good news? An MRI is a common imaging test that gives doctors a detailed look inside your body. Learning how to prepare and what happens during the scan can help you feel more comfortable and confident.

What Is an MRI?

Magnetic resonance imaging (MRI) uses powerful magnets and radio waves to create detailed images of organs, tissues and other structures inside your body. Unlike X-rays and CT scans, an MRI does not use ionizing radiation.

Doctors may recommend an MRI to help diagnose injuries, evaluate symptoms or monitor certain medical conditions.

How to Prepare for Your First MRI

Before your appointment, your care team will provide instructions based on the type of MRI you’re having. A few things to keep in mind:

Remove metal items. Jewelry, watches and other removable metal items must be removed before your MRI. Tell your care team if you have piercings, implanted medical devices or metal in your body.
Wear comfortable clothing. You may be asked to change into a hospital gown.
Share important health information. Tell your care team if you have kidney disease or could be pregnant.
Follow your preparation instructions. You can typically eat, drink and take medications as usual. However, some exams require special preparation.

If you’re nervous about enclosed spaces, let your care team know before your appointment. They can discuss options to help you feel more comfortable.

What Happens During an MRI Scan?

When it's time for your scan, an MRI technologist will help you lie on a padded table that slides into the scanner.

Here's what to expect:

Getting positioned: Your technologist will help position you comfortably and provide earplugs or headphones.
Taking the images: You'll hear tapping or thumping sounds as the machine captures images. These noises are normal.
Staying still: You'll need to remain as still as possible to help produce clear images.
Staying connected: Throughout the scan, your technologist can see, hear and communicate with you.

What Happens After an MRI?

Once your MRI is complete, you can typically return to your normal activities right away unless you received medication to help you relax.

A radiologist will review your images and send a report to the provider who ordered your exam. Your provider will discuss the results and any recommended next steps.
