Prior to MRI scans, we require all patients to complete a safety screening form(s). You may wish to complete these prior to your appointment:

Claustrophobia
As the MRI scanner is an enclosed space, occasionally claustrophobia is a problem for some patients. If you have claustrophobia or anxiety, you may opt to receive a light sedative. If this is the case, you need to contact our MRI staff on (09) 523 7054 ext 2 at least 24 hours prior to your scan for information and assistance.
If you are having sedation for your scan you will require a support person to accompany you to your appointment. This support person MUST stay in the department for the entire time. Following your scan, you will require a driver as the effects of the sedative will last some time, and as such, you must refrain from any significant activity for the rest of the day. You should neither drive a car nor operate any machinery.
Metallic Foreign Bodies
Those people who have had metal in their eyes from grinding metal should contact us before their scan. In some cases an x-ray will need to be taken to ensure that all the metal has been removed. Other metallic foreign bodies such as shrapnel may also require an x-ray prior to an MRI.
Tattoos, Fillings and Dental Braces
Dyes used in tattoos may contain iron and could heat up during MRI, but this is rarely a problem. Dental fillings and braces usually are not affected by the magnetic field but they may distort images of the facial area or brain, so the radiologist should be aware of them. Please advise our staff prior to your scan.
Pregnancy
Women should always inform the MRI technologist if there is any possibility that they are pregnant. Because the risks of an MRI exam to the unborn foetus are unknown, pregnant women should not have this exam unless the potential benefit from the MRI is assumed to outweigh the potential risks.
Contrast Dye (Gadolinium)
Some MRI examinations may require that the patient receive an injection of gadolinium based contrast into the bloodstream. You will be asked if you have allergies, however Gadolinium based contrast agents used in MRI are very safe and do not contain iodine, making it less likely to cause an allergic reaction.
You must advise us if you have kidney disease or diabetes and especially if you are undergoing renal dialysis. These conditions may prevent you from having the contrast agent.
All patients are required to change into a gown that has been provided and remove all:
- Jewellery (including body piercings)
- Watches
- Hairclips
- Glasses
- Wallets/purses
- Hearing aids
- Any other metallic objects
