How long does a cardiac MRI take?

Consultant cardiologist Dr Joban Sehmi reveals how long a cardiac MRI takes.

If you are referred for a cardiac MRI, you’ll be asked to come in approximately half an hour before your scan time. You’ll be met by a member of the MRI team who will go through a safety questionnaire to ensure that it’s safe for you to be in an MRI environment. Once this is complete, you’re often asked to change into a hospital gown, and a small tube is placed in a vein within your arm through which dye can be given.

The MRI itself is in a specialized room. The MRI scanner looks rather like a large tunnel. Once you’re in the machine itself, it is rather noisy, and you will be given headphones for your protection. The technician carrying out the MRI will be in constant contact with you via the headphones. The MRI scan itself is rather noisy, and it can be quite disconcerting, but again, after five minutes, you will become accustomed to that environment.

The scan itself lasts about 45 minutes to an hour, and towards the end of the scan, a dye is administered, and more detailed images are taken. After the scan, you’re normally monitored for about 15 to 20 minutes to ensure that you’re well and you have no adverse effects from the dye. After which, you’ll be allowed to go home.

I invite you to book a consultation with Many Beats if you have any concerns about your heart health or if you’re concerned about risks for heart health going forward. We will see you in a timely fashion in a location in London, and we’ll provide you with very streamlined services so you can get a lot of investigations done, and a definitive management plan, which is tailored to you as the individual.
