MRI (Magnetic Resonance Imaging)
BMI have two MRI scanners (Siemens 1.5 Tesla & 3.0 Tesla) located at University Hospital Geelong.
What to expect?
During the scan you will be lying inside the centre of a large circular magnet, it is important that you remain very still during the scan. Any slight movement can blur the images and reduce their usefulness.
The MRI scanner will make some loud buzzing and knocking noises. Headphones will be provided to reduce the loud noise and allow you to listen to music or watch TV (available for some scans)
You can bring a CD or we can connect your music player to the scanner, allowing you listen to your favourite music during the scan.
What is MRI?
MRI stands for Magnetic Resonance Imaging. It is an imaging technique which uses a very strong magnet and radio waves, to make images of inside the body. MRI does not use x-rays.
The images produced can be acquired in different ways to demonstrate specific body structures and diseases. MRI shows most tissues of the body including muscles, nerves, brain, discs, ligaments and bones.
How long does the MRI take?
Most MRI scans take between 20 and 40 minutes. Our radiographers will communicate to you during the scan through an intercom system.
Preparation for MRI
- Fill out the MRI Safety Questionnaire. A relative may assist with this if required.
- Change into a gown and remove all external metal objects (including all jewellery and body piercings)
For most scans there is no other preparation required. Food, drink and medication can be continued.
If preparation is required – this will be discussed with you at time of booking and instructions sent to you with your booking confirmation letter.
If you have experienced claustrophobia, or have trouble in enclosed spaces, please discuss this with MRI staff when making your appointment or notify us before your appointment date.
Due to the strong magnetic fields used, patients and accompanying staff need to be aware of several important safety issues.
You are not allowed to enter the MRI scan room if you have certain types of:
- Implanted cardiac pacemaker (not MRI safe)
- Infusion pumps
- Brain aneurysm clips
- Cochlear (hearing) implants
- Metal foreign body in your eye
No metal objects can be taken inside the scan room. This includes things such as jewellery, keys, paper clips and scissors. They can be attracted to the magnetic field and become dangerous missiles.
No electronic or magnetic sensitive devices can be taken inside the scan room. This includes things such as mobile phones, pagers, watches and credit cards. The magnetic field can stop these devices from working.
