Cardiac MRI

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
  • Defibrillator
  • Cochlear Implant
  • Neurostimulator
  • 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.

Your MRI will be performed by an 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 heart muscle.

You will be asked to lie down on the MRI bed on your back. We’ll make you as comfortable as possible using pillows and blankets. You will need to lie still for about one hour. During this time you will be asked to hold your breath for short periods at a time (10-15 seconds) when requested by the radiographer.

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 radiographer or stop the exam.

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.


The cost of an MRI will depend on the reason for your scan, and who referred you. We can provide you with a quote at the time of booking.
