What is a cardiac MRI?
A cardiac MRI is performed on using Magnetic resonance imaging (MRI) which is a safe, non-invasive test that creates detailed pictures of your organs and tissues using radio waves, magnets, and a computer. MRI does not use ionizing radiation or carry any risk of causing cancer.
Cardiac MRI captures pictures of the heart and major blood vessels that assist Imaging Central’s reporting cardiologist to identify the most appropriate treatment for your heart condition.
What can a cardiac MRI scan in Perth diagnose?
Cardiac MRI is used to diagnose and assess diseases and conditions, such as:
- Heart valve problems
- Coronary heart disease
- Damage caused by a heart attack
- Heart failure
- Cardiac tumours
- Congenital heart defects
- Pericarditis (a condition whereby the membrane, or sac, around your heart is inflamed)
What is required to prepare for the cardiac MRI?
If you require an MRI scan, we require you to make an appointment and answer some qualifying questions prior.
If you have one of the following, it MAY NOT be safe for you to have an MRI scan:
- Cardiac pacemaker
- Cochlear Implant
- Cerebral Aneurysm Clip
- Metal in your eyes
- Artificial Heart Valve
- Infusion Pump
Please bring any previous films with you to your appointment. All body piercings, jewellery and metal objects will need to be removed prior to your scan.
What happens during a cardiac MRI?
The cardiac MRI scan at Imaging Central will be thoroughly explained to you by our Radiographer prior to beginning.
As part of preparations for an MRI scan, patients change into a comfortable gown. This is all in the name of safety and helps maintain a metal-free area around the MRI machine. Patients also pass by a special ferrous metal detector to check for any metal that may have been overlooked while changing and that may pose a risk as they enter the MRI suite. Every care is taken to ensure the safest, most comfortable experience possible.
You will be asked to lie on the scan table. The part of your body to be scanned will be carefully positioned and gently secured, so you are comfortable and more likely to remain still. Small devices, called coils, may be positioned around the body part that is being studied. These coils are receivers, which enhance the picture quality.
A contrast may be given during certain MRI tests through a vein in the back of your hand or your forearm. The contrast helps the radiologist demonstrate certain areas more clearly. When you make a booking for an MRI scan that may require IV contrast you will be asked for your age and whether you are diabetic or if you’ve had any trouble with your kidneys. We may need the results of a blood test within the past 3 months that shows your kidney function. If you have not had one within the past few months we will ask you to get your doctor to write you a referral for a blood test or you can come to see us and we will provide you with one. We need to establish that your kidneys work well before we give you an injection of contrast. There are several options available for MR contrast which is gadolinium-based. We only use the safest agents available on the market today, which are macrocyclic chemical bonds (for those chemistry buffs!).
The scanning process is painless. However, if you are claustrophobic, please inform our staff prior as a sedative may be provided.
To ensure the quality of the images captured, it is very important to remain still throughout the procedure.
