What is an MRI and how can it help me?

Magnetic resonance imaging (MRI) is a type of test. It lets your healthcare provider see pictures of the inside of your body. MRI uses strong magnets, radio waves, and a computer to make an image. Because it uses strong magnets, you need to tell the healthcare team about any metal in or on your body.

How do I get ready for an MRI?

  • Follow any instructions for not eating or drinking before the test.

  • Ask if you should stop taking any medicine before the test.

  • Don’t wear makeup. Some makeup contains metal.

  • You will be asked if you have any metal in or on your body. This includes electronic devices or implants. It includes metal plates, screws, clips, pins, or wires. Tell them if you may have any other metal pieces in your body, such as metal shavings or metal left from an injury.

  • Remove your watch, jewelry, and hearing aids. Take all objects out of your pockets. This includes credit cards, pens, pocketknife, glasses, and other objects that may have metal.

What happens during an MRI?

Most MRI tests take 30 minutes to 1 hour. But the test may take longer. This depends on the type of MRI you have. During this time:

  • You may be asked to wear a hospital gown.

  • You may be given earplugs to wear. This is because the MRI machine can be loud.

  • You may be injected with a special dye called contrast. This makes the MRI image better. 

  • You’ll lie down on a platform. The platform then slides into the MRI machine.

  • You’ll need to lie still as directed. Follow all instructions from the healthcare team during the scan.

  • The platform slides out of the MRI machine when the test is done.

What to tell your healthcare provider

Tell the healthcare team if you:

  • Have had an imaging test such as MRI or CT with contrast dye

  • Ever had a reaction to contrast dye

  • Are allergic to iodine or shellfish

  • Are allergic to any medicines

  • Have diabetes or kidney disease

  • Had a liver transplant

  • Have any other serious health condition

  • Are or may be pregnant

  • Are breastfeeding

What happens after an MRI?

  • You can go back to normal activities right away.

  • Contrast dye will pass naturally through your body within 1 day. You may be told to drink more water or other fluids during this time. 

  • Your healthcare provider will discuss the test results with you. This may be done during a follow-up visit or over the phone.

  • Your next appointment is: __________________

 

What can I expect during an MRI?

The magnetic resonance imaging unit is a large metal tube with a padded table that slides into it. As the scan starts, you may hear a thumping or humming sound. Having this type of noise close to your head can be worrisome, but you are not in any danger. Hearing protection is available, and you are welcome to bring music to help you feel more at ease.

Here is additional information about what to expect:

  • Clothing and accessories: Metal items like zippers, jewelry, watches, hearing aids and belt buckles are not allowed near MRI units. Please leave these items at home.
  • Food and medications: Eat and take medication as you usually would unless we tell you otherwise.
  • MRIs for children: Dress your child in comfortable clothing without zippers or snaps. Bring a favorite soft toy or blanket to provide comfort during your child’s MRI.
  • Billing: You will receive two bills. One is from the facility, and the other is for the radiologist who reads the results. Check with your insurance for specific billing charges to expect.

When is an MRI necessary?

Your care team may order an MRI when we can’t pinpoint a cause for your symptoms using other imaging tests. Conditions we assess with magnetic resonance imaging include:

Neurological issues

MRIs help us detect and monitor conditions such as multiple sclerosis, stroke, hydrocephalus or spinal cord injuries.

Orthopedic concerns

You may benefit from an MRI if doctors need to confirm or rule out cartilage injuries, a slipped disc in your back or a torn ligament.

Cardiovascular issues

We use MRI to assess heart structures and function. It can help us pinpoint the cause of chest pain or unexplained fainting.

Gastrointestinal disorders

An MRI helps us detect issues in your digestive tract, including inflammation, obstructions, blood clots, organ damage and gallstones.

Trauma

An MRI helps us determine which internal structures are affected and how severe an injury is if you experience a bad fall, collision or other trauma.

Tumors and cancer

MRI helps detect growths in the brain, spinal cord, breast, cervix, bladder and other body parts. It shows how deep into the tissue a tumor has grown.

Vascular anomalies

MRI helps determine whether atypical blood vessel formations are cosmetic concerns or something requiring treatment.
