An MRI produces images of the body without the need to have an Xray but it is not suitable for everyone. You cannot have an MRI if you have:
- Cardiac pacemaker
- Cochlear implant
- Metal aneurysm clip in the brain
- Retained metal fragments in the eye
- Programmable hydrocephalus shunt
- Some other types of biomedical implants
- You may also be excluded if you are pregnant.
What do I need to do before my scan?
You will be asked to fill in a safety questionnaire. You will also be asked to confirm your appointment by telephone.
What will happen during my scan?
You may need to change into a hospital gown. You will be asked to remove any dentures, jewellery, hearing aids, hairpins and eye makeup. The radiographer will check your safety questionnaire with you and explain what is going to happen. You will have the chance to ask any questions.
During the scan you will need to lie flat on your back on a couch. This is then moved into the magnet. You will hear some noise from the scanner which is quite normal. You will be given the option of listening to music during your scan. The radiographers will make you as comfortable as possible as it is essential that you lie still for the duration of your scan.
For some scans it may be necessary for you to have an injection of a special ‘dye’. This is done at your elbow and is similar to having a blood test.
Can someone stay with me while I have my scan?
Not normally. However, for children and people who are very anxious this may be possible providing that it is safe for the companion to enter the scan room.
How long will it take?
Your scan will usually take between 30 minutes and 1 hour.
Will it hurt?
No. You will not feel any discomfort from the scan.
When will I get my results?
You scan will be looked at by one of our x-ray doctors who will send the results to the doctor that referred you. This normally takes between 7 and 10 days.
