A MRI is an advanced medical imaging tool which uses a strong magnetic field and radio waves to produce detailed imaging of internal organs making it ideal for imaging the heart.
Cardiac MRI is most commonly used for screening and diagnosis of the function of the heart.
How do I prepare?
When you book in for your MRI and at your appointment, you will be asked certain safety questions. This is because an MRI machine is essentially a large magnet and certain implants are not MRI safe or only safe on certain machines. Please let bookings staff and the MRI Radiographer know if you have any of the following:
- Cardiac Pacemaker
- Cochlear Implant
- Aneurysm Clips
- Active Implanted Biomedical Devices
- Infusion Pump
- Any implants or devices in your head or body
In some instances, you may find the MRI machine claustrophobic which could prevent you from having the imaging done. If this is the case, or if you have experienced this previously, let us know and we will talk through the options available to you.
Technology and Team
At Queensland X-Ray we can provide referrers and patients with a choice between 3T and 1.5T scanners. The number refers to the strength of the magnetic field created by the MRI machine. It’s recommended Cardiac MRI is done on a 3T scanner.
We also have wide bore options in limited locations. The wide bore offers slightly more space inside the MRI tube so it may help those who suffer from claustrophobia.
Your MRI will be performed by a MRI Radiographer. These are Radiographers who have undergone additional training and exams in order to operate an MRI scanner. The images the MRI captures are viewed by a Radiologist who makes a diagnosis.
What happens during my examination
You will be asked to change into a gown before your MRI. This is to ensure you are wearing nothing with metal in it.
When entering the MRI room, your MRI Radiographer will explain exactly what will happen during your procedure. It may vary slightly from what we describe below, so don’t worry.
In most cases we will insert an intravenous (IV) line into your arm. We will use this to give you some contrast, which will enhance the images we take of the breast tissue.
You will be asked to lie down on the MRI bed on your back. You will enter the bore or hole of the MRI feet first. We’ll make you as comfortable as possible using pillows and blankets.
When the MRI machine is taking the images, you will hear a loud banging noise. You’ll be offered headphones through which the MRI Radiographer can talk to you and play a selection of music to help the time pass more quickly. You will be given a button to press should you at any time want to talk to the Technician or stop the exam.
Once in position the MRI Radiographer will leave the room, and the bed will move slowly into the scanner so you are positioned in the centre of the machine.
You will need to lie very still for up to 45 minutes.
After your examination
The results of your Cardiac MRI will be sent directly to your referring Doctor. Please ensure you book a timely follow-up appointment to discuss your results with them.
There is no cost difference between a 3T or a 1.5T scanner.
Some MRI scans are rebatebale on certain machines across the state. Please ask at the time of booking for more information.
