What Patients Commonly Experience During an MRI

Magnetic Resonance Imaging (MRI) is a vital tool in modern diagnostics, particularly valued for its ability to provide detailed images of soft tissues such as the brain, spine, joints, and internal organs. For many patients, however, undergoing an MRI scan can be an unfamiliar and sometimes daunting experience. While the scan is painless and non-invasive, understanding what typically happens during the process can help demystify it and put you at ease.

Before Your Scan: What to Expect

Once your doctor refers you for an MRI, the process begins with a safety questionnaire. This is an important step that allows the radiology team to confirm the scan is safe for you. You’ll be asked about any metallic implants, pacemakers, or a history of claustrophobia, since these details help prevent complications and allow the staff to tailor the procedure to your needs.

Getting Ready at the Imaging Centre

When you arrive, the staff will guide you through the process. You’ll need to remove any metal items like jewellery or glasses, and change into a hospital gown to avoid interference with the scanner’s magnetic field.

As part of this preparation, you’ll also have the process of magnetic resonance imaging explained to you in clear terms. This step ensures you understand what happens during the scan, why certain precautions matter, and gives you an opportunity to ask questions so you feel more confident going in.

Inside the MRI Room

You’ll lie down on a padded table that slides into the scanner—a large, tube-like machine. The radiographer will position you based on which part of your body needs imaging. You may be given cushions or pads to help you stay comfortable and still, which is important for capturing clear images.

Sometimes, a contrast agent is used to improve the quality of the images. If that’s needed, it will be injected through a small cannula in your arm. You might feel a cool sensation, but most people don’t notice anything unusual.

The Noises and Sensations You’ll Notice

Once the scan begins, the machine will start making loud, repetitive noises, often described as clunks, buzzes, or knocking sounds. These are caused by the machine’s gradient coils. You’ll be given earplugs or headphones to reduce the noise, and in some places, you might even get to listen to music.

The scan itself won’t cause any discomfort. You won’t feel the magnetic field or radio waves, and there’s no exposure to ionising radiation. Your main job is to lie still and relax.

Staying in Contact During the Scan

Although you’ll be alone in the scanning room, the radiographer will be monitoring you from outside and can talk to you through an intercom. You’ll also have a button to press if you need help or want to stop the scan.

How Long It Takes and What You Might Feel

The duration of the scan varies depending on which part of your body is being imaged, but most scans last between 15 and 45 minutes. Some may take a bit longer. You’ll hear instructions to hold your breath briefly or stay extra still during certain parts of the scan.

Physically, you probably won’t feel much at all. There’s no contact from the scanner itself, and the environment, while a bit noisy and enclosed, is tolerable for most people. Staying relaxed and focused on your breathing can help the time pass more quickly.

After the Scan: What Happens Next

Once the scan is over, the table will slide out, and you can get up and change back into your clothes. Unless you’ve had sedation, you’ll be able to carry on with your day as normal. If contrast was used, drinking water afterwards can help flush it out of your system.

Your images won’t be reviewed immediately—a radiologist will study them and send a report to your referring doctor, who will then go over the results with you. This usually takes a few days.

Putting the Experience into Perspective

Getting an MRI might seem intimidating at first, but once you know what to expect, it becomes far less daunting. You’ll be supported by trained professionals, the procedure itself is completely painless, and you’re actively involved by staying still and following simple instructions.

By understanding each step of the process, from preparation to the scan itself, you can approach your MRI with greater confidence and clarity.
