Magnetic Resonance Imaging (MRI) uses an exceptionally strong magnet, radio frequency waves and a sophisticated computer to generate detailed images of the body. No X-rays or ionising radiation is used.
The magnetic field and radiofrequency waves have not been shown to cause any long-term effects, but please advise our staff before your MRI if you know you are, or could possibly be pregnant.
Our MRI bookings staff can discuss whether a Medicare rebate is available for your scan, at the time of booking. Please contact them on +61 (0) 8 9726 6965.

As the MRI is a very strong magnet it is important for us to know at the time of your booking if you have any of the following:
- Cerebral Aneurysm Clip
- Cardiac Pacemaker
- Artificial Heart Valve
- Metal in your eyes
- Pregnancy (1st trimester)
- Infusion Pump
- Cochlear Implant
It is also important for us to know whether you’re claustrophobic, as sedation from your GP can be organised to help you feel more comfortable. However we must be aware of this, as your preparation differs.
The scanner consists of a large tube that is open at both ends. The tube contains a powerful magnet. The patient lies on a motorised bed, which is moved inside the tube during the scan.
Upon arrival, we will ask you to complete a detailed MRI safety questionnaire. The MRI radiographer will decide whether you need to change into a gown for your exam and run through any questions you may have.
Once you are positioned as comfortably as possible onto the MRI scanning bed it is important to stay still for the entire duration of the scan – typically 15-40 minutes. If you feel claustrophobic or uncomfortable it’s important to let the MRI radiographer know as soon as possible.
Though the MRI radiographer is operating the scanner from outside the scan room you will be observed at all times and can communicate with them using the intercom provided. For most scans you can also listen to music through the headphones provided. Feel free to bring your favourite CD along. The scanner creates loud rumbling and knocking noises. This is normal and how the scanner produces images. The headphones will block out the majority of the noise.
For some scans our specialists will require you to have an injection of MRI contrast. The contrast is injected intravenously into your arm or hand. Please let us know prior to the scan whether you have any kidney problems, as this may prevent the use of the contrast.
- Bring the MRI Request form given to you by your doctor.
- Please bring any previous relevant X-rays, CT, MRI or ultrasound films, as the radiologist reporting your MRI may need this information.
- Avoid wearing any jewellery or metallic objects – if you have piercings within the area to be scanned please remove. Also avoid make-up if you require a scan of your head or neck.
You may be asked to change into an examination gown prior to scan.
The magnetic field can erase credit cards, electronic devices and immobilisers. You will be asked to remove all of these objects which will be stored securely for the duration of the scan.
At the time of your scan, the images will be reviewed for clarity and accuracy.
Our Radiologist will conduct a detailed study of your examination and will forward the report to your doctor. The images obtained during your scan, will be made available to you directly after your scan.
At Global Diagnostics, we accept MRI referrals from medical specialists, GPs and allied health professionals. It is important to note that not all MRI examinations are Medicare rebateable. GPs have access to a limited number of MRI examinations for both adult and paediatric patients. Medical specialists have access to a larger number of MRI examinations.
