MRI is useful for showing structures such as the brain, spinal cord, internal organs, muscles, ligaments and cartilage.
Commonly asked questions about MRI scans
MRI is a safe scan with no known harmful effects. MRI does not use x-rays or involve any radiation.
MRI uses a strong magnetic field and radio waves to produce images of any part of the body, in any direction. MRI is particularly good for showing structures such as the brain, spinal cord, internal organs, muscles, ligaments and cartilage.
To be sure that it is a safe for you to enter the magnetic field, you will be sent an MRI Safety Screening Form to complete.

You may be asked to fast for 2 hours immediately before your examination (you will be informed if this is necessary for your examination at the time of booking). Please continue to take your regular medication unless advised not to by your doctor.
You will be asked to change into hospital clothes and remove all jewellery and metallic objects. You will not be able to enter the MRI scan room with objects such as your wallet, credit cards, mobile phone, or watch. The magnetic field will damage these items.
You will be interviewed by the radiographer, who will review your MRI Safety Screening Form with you and ask about your medical history.
You may need an intravenous line inserted.
MRI scans vary in length depending on the exam being done. Your scan may take anywhere from 15 min to 1 ½ hours. The radiographer will let you know the expected length of time for your exam.
MRI scanners are noisy. You will be given earplugs to wear during the examination. Sometimes, it is possible to give you headphones so that you can listen to music. This is not always possible, as the headphones are not compatible with some equipment.
You will be asked to lie as still as possible as any movement can make the images blurry.
The radiographer will keep in contact with you throughout your examination and you will be able to communicate with them as well.
The radiologist’s report and your images are automatically forwarded to your referring doctor, and you'll need to make an appointment with them to discuss the results.
If you needed sedation for your scan, you will need to remain in the department for some time afterward (time varies person to person) to ensure you that you recover from it fully. You will also need someone to take you home safely, as you will not be able to drive for 24 hours.
