Have you, or a loved one, been referred for a cardiac MRI? If so, here’s a quick explainer to help you feel more informed ahead of your appointment.
🫀 What is a cardiac MRI?
A cardiac MRI is a scan that uses a magnetic field and radio waves to take detailed pictures of your heart and surrounding tissues. While MRIs are used across the body to investigate a range of conditions, a cardiac MRI focuses specifically on the heart and blood vessels. It’s one of several imaging tests that may be used to assess your heart — and it can provide crucial information to guide your treatment plan and care.
🫀 Why is someone sent for a cardiac MRI?
A cardiac MRI can help to:
• Detect abnormalities in the heart’s structure or function
• Assess damage from a previous heart attack
• Diagnose heart muscle disease or inflammation
• Identify congenital defects or heart tumours
🫀 What happens during a cardiac MRI?
You’ll lie on a table that slides into the MRI machine, where detailed images of your heart are taken. You may be asked to briefly hold your breath while each image is captured. The scan is painless and typically takes about 45 minutes. The machine can be noisy, so you’ll be able to communicate with your care team throughout the process via headphones.
🫀 What happens after the scan?
Once your scan is complete, your doctor will review the images and explain what they show. The results may be used to confirm a diagnosis, monitor a known condition, or plan the next steps in your treatment and care.
