MRI Cardiac Scans Sydney
MRI Cardiac (Cardiac MRI / CMR) is an advanced, radiation-free scan that provides detailed images of the heart’s structure, function, and blood flow. It is one of the most accurate tools for assessing cardiomyopathy, heart muscle scarring, congenital heart disease, and complex cardiac conditions. All Medicare-eligible cardiac MRI studies are fully bulk-billed at Advicon Imaging.

Description of MRI Cardiac
MRI Cardiac uses powerful magnetic fields to create high‑resolution images of the heart in motion. Unlike CT or X‑ray, cardiac MRI does not use radiation, making it safe and suitable for repeated follow‑up imaging where required.
Cardiac MRI can assess:
- Heart size and pumping function
- Cardiomyopathy (dilated, hypertrophic, restrictive)
- Myocarditis and inflammation
- Cardiac scarring or fibrosis
- Ischaemic heart disease
- Congenital heart abnormalities
- Pericardial disease
- Valvular abnormalities
- Cardiac masses or thrombus
- Right ventricular function (common in pulmonary hypertension)
Using specialised sequences, cardiac MRI can evaluate tissue characteristics, blood flow patterns, delayed enhancement, and stress responses (if stress protocol is requested).
Contrast (gadolinium) is commonly used to assess scar tissue, inflammation, and viability of the heart muscle.
At Advicon Imaging, cardiac MRI is performed using modern equipment and interpreted by specialist cardiac radiologists. Medicare‑eligible referrals are fully bulk‑billed.
Additional Notes
Certain implanted cardiac devices are MRI‑conditional. Please bring device information and your device card to your appointment.

Frequently Asked Questions
Why do I need a cardiac MRI?
Your doctor may be investigating cardiomyopathy, inflammation, scarring, structural abnormalities, or reduced heart function.
Is it safe?
Yes. MRI uses magnetic fields, not radiation. However, you must inform us if you have pacemakers, defibrillators, or other implanted devices.
Will I need contrast?
Most cardiac MRI studies use gadolinium contrast to evaluate scarring and inflammation. It is generally safe and well tolerated.
Do I need preparation?
Yes:
- Avoid caffeine for 12–24 hours before the scan (important for heart rate control).
- Continue regular medications unless advised otherwise.
- Leave all metal objects at home.
- Notify us if you are pregnant, breastfeeding, or have kidney problems.
How long does the scan take?
Cardiac MRI takes longer than standard MRI—usually 40–60 minutes due to multiple sequences.
What happens during the scan?
You will lie on the MRI table with ECG leads placed on your chest. You will be asked to hold your breath for short periods while images are taken.
Is the scan noisy?
Yes. Ear protection is provided.
Will I feel unwell afterwards?
Most people feel completely normal. If contrast is used, mild warmth may be felt briefly.
Can I drive after the scan?
Yes, unless sedatives were required (rare).
When will my doctor get the results?
Typically within 24–72 hours, depending on complexity.
Is this scan bulk‑billed?
Yes. All Medicare‑eligible cardiac MRI studies are fully bulk‑billed at Advicon Imaging.
