Cardiac Magnetic Resonance Imaging (MRI)

What is a Cardiac Magnetic Resonance Imaging (MRI)?

Cardiac Magnetic Resonance Imaging (MRI) is a non-invasive imaging test that uses powerful magnets and radio waves to create detailed images of the heart and its structures. It helps evaluate heart function, detect heart disease, and assess damage from heart conditions.

What happens during a Cardiac Magnetic Resonance Imaging (MRI)?

​

During Cardiac MRI, you will go through a cylindrical MRI machine which will take detailed images of your heart. Additionally, you may be given a contrast dye through an IV to enhance the images of your heart. The procedure typically lasts between 30 to 60 minutes.

Why would I need a Cardiac Magnetic Resonance Imaging (MRI)?

​

You might need a Cardiac MRI if:

• You have symptoms such as chest pain, shortness of breath, or unexplained fatigue.

• Your doctor needs to assess the function and structure of your heart in detail.

• There is a need to evaluate heart disease, damage from a heart attack, or congenital heart defects.

​

Who needs a Cardiac Magnetic Resonance Imaging (MRI)?

​

A Cardiac MRI may be necessary for:

• Patients with suspected heart disease or abnormalities

• Individuals with inconclusive results from other cardiac tests

• Those needing detailed evaluation of heart function or structure

​

What are the risks of Cardiac Magnetic Resonance Imaging (MRI)?

​

Cardiac MRI is generally safe with minimal risks, including:

• A small risk of allergic reaction to the contrast dye, if used

• Discomfort or anxiety from lying still in the MRI machine

• Rare cases of claustrophobia due to the confined space of the MRI machine

​

It's important to note that these risks are rare and the benefits of the test typically outweigh the risks. Additionally, the test is performed under the supervision of trained medical professionals who are equipped to handle any complications that may arise. Your doctor will review your medical history and assess your overall health to determine whether the benefits of the test outweigh the risks for you. If you have concerns about the risks of a stress echocardiogram, discuss them with your doctor before the test.

How do I prepare for a Cardiac Magnetic Resonance Imaging (MRI)?

​

To prepare for a Cardiac MRI:

• Follow your doctor’s instructions, including fasting for a few hours before the test.

• Inform your provider of any allergies, particularly to contrast dye, and discuss any medications you are taking.

• Remove all metal objects, including jewellery and watches, before the test.

• Wear comfortable, metal-free clothing.
