Magnetic resonance imaging (MRI)
Magnetic resonance imaging (MRI) uses a magnetic field and pulses of radio wave energy to build a detailed picture of the inside of your body.
MRI allows us to see your organs and internal body structures to help diagnose and treat disease.
MRI covers an extensive range of examinations including:
How to prepare for your test
- Some MRI procedures require specific preparation. We will send you instructions with your appointment letter.
- Please tell us if you are or suspect you might be pregnant or are breastfeeding. · Please arrive 30 minutes before your appointment to complete an MRI Safety Questionnaire (patients to complete first page ONLY and bring with you to your MRI appointment) to ensure you are safe to enter the MRI room.
- You will need to remove all items of jewellery and clothing which contain metal such as buttons, zips, wire in undergarments, keys and credit cards.
- You will be allocated a change cubicle and instructed to put on a gown.
What happens during the procedure?
- You will be asked to lie on a detachable table which will be wheeled and docked on the MRI scanner.
- The MRI machine is like a long cylinder that is open at both ends.
- The machine is very noisy and you may hear thumping and knocking sounds (like a jackhammer). You will be offered ear plugs or headphones and music.
- You will not feel anything during the scan. Different pieces of equipment may be placed over you, depending on the body part being imaged.
- MRI staff will not be in the room with you during the scan but can see and talk to you at all times. You will be given a call button to use if you need help.
- The scan will take between 15 and 90 minutes. It is extremely important that you keep completely still during the scan. Any movement can blur the pictures.
- Depending on the area being scanned, you may be given MRI contrast.
- A fine needle (IV cannula) will be put into a vein in your arm to inject the MRI contrast.
- For more information on MRI contrast and the risks involved in its use, please read the MRI Contrast Patient Information Sheet.
What happens after the procedure?
You can eat and drink normally after your scan is finished. Your results will be sent to your doctor.
