An MRI is painless and most scans need little preparation. The one thing that makes an MRI different from other scans is safety screening for metal and implants, because the scanner uses a powerful magnet that is always on. This simple guide walks you through how to prepare for an MRI — before, during and after — so your appointment goes smoothly and the images are clear. Always follow the specific instructions from your scan centre, as they take priority.
An MRI (magnetic resonance imaging) scan uses a strong magnetic field and radio waves — and no ionising radiation — to produce highly detailed images of soft tissues, organs, joints, the brain and the spine. For most people, preparing is straightforward: you can usually eat and drink normally, take your regular medicines, and turn up in comfortable clothing. What makes an MRI different is that the magnet is always on and very strong, so every patient is screened for metal and implants before going anywhere near the scanner.
The checklist below covers what to bring, what to remove, when fasting applies, and what to tell the team — so your scan is safe and the images come out clear. If your scan relates to a cancer concern, CION’s oncology team can review the findings and advise the right next step. If an MRI raises a question, you are welcome to a free written second opinion before deciding what to do next.
An MRI scanner’s magnet is always on — even when no scan is running — and it is powerful enough to pull loose metal forcefully across the room. That is why honest metal and implant screening, and removing every metal item before you enter, is the single most important step in preparing for an MRI.
A little planning makes the appointment smoother. Here is what to do — and what to bring — before an MRI:
Because the magnet is always on and very strong, every patient completes a safety questionnaire. Answer it fully and honestly, and bring any implant card you have. Tell the team about anything implanted or any metal in your body, including:
Before entering the scanner room you must remove all metal — jewellery, watches, hairpins, glasses, removable dental work, hearing aids and piercings — and leave phones, cards and coins outside. The magnet can pull loose metal forcefully, so nothing metallic should go in with you.
Some MRIs use a gadolinium-based dye to make certain tissues stand out. If your scan needs contrast:

You will lie on a table that slides into the scanner. The MRI is painless, but you must lie still so the images are sharp, and you may be asked to hold your breath briefly for some scans. The machine is loud — the knocking is the magnet working — so you will be given earplugs or headphones, and you can speak to the team through an intercom and hold a call buzzer. If contrast is given, you may feel a brief cool sensation. Most scans take about 30–60 minutes.
You can usually return to normal activities straight away. If you were given contrast, drink plenty of water to help flush it out. A radiologist reviews your scan, and the report is typically ready the same day or by the next day, depending on the study and centre.
If enclosed spaces are difficult, ask about a wide-bore or open scanner, music or an eye mask, going feet-first where possible, or a mild sedative arranged with your doctor. For children, explaining the steps in advance helps; the scan is painless, and young children sometimes need help — or occasionally mild sedation — to stay still for clear images.

Most MRIs need little preparation: carry your prescription, complete the metal and implant safety screening, remove all metal, and follow any fasting instructions for contrast or abdominal scans. Tell the team about pregnancy, kidney problems, allergies, implants or claustrophobia.
For most MRIs, no. For some contrast studies, MRCP or abdominal scans you may be asked to fast for about 4–6 hours. Follow the specific instructions from your scan centre.
Comfortable, loose clothing without metal. You will often change into a gown and must remove jewellery, watches, hairpins, glasses, removable dental work and hearing aids.
Many implants are safe ('MRI-conditional') under specific conditions, while some are not suitable. Always declare any implant or metal so you can be screened correctly — this is the most important safety step.
Most scans take about 30–60 minutes. A companion can usually wait nearby, which is especially helpful for children or anyone who feels anxious.
Ask about a wide-bore or open scanner, music or an eye mask, feet-first positioning, or a mild sedative arranged with your doctor. The team can talk to you throughout and you can hold a call buzzer.
