MRI (magnetic resonance imaging) is a test that uses a magnetic field and pulses of radio wave energy to make pictures of the organs and structures inside the body. An MRI of the heart looks at the structures and blood vessels of the heart.
When you have an MRI, you lie on a table and the table moves into the MRI machine. A special dye (contrast material) may be put in a vein (IV) in your arm or hand to make the blood vessels easier to see on the scan.
An MRI of the heart is done to look at the structures and blood vessels of the heart. These may include:
In general, there's nothing you have to do before this test, unless your doctor tells you to.
Tell your doctor if you get nervous in tight spaces. You may get a medicine to help you relax. If you think you'll get this medicine, be sure you have someone to take you home.
The test usually takes 30 to 60 minutes but can take as long as 2 hours.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse advice line (811 in most provinces and territories) if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
