Question 1

Is a Cardiac MRI safe for patients with implants?

Accepted Answer

A. Cardiac MRI safety depends on the type of implanted devices. Many modern pacemakers and defibrillators are MRI-compatible under specific conditions, but always consult the radiologist to verify if your device meets safety guidelines.

Question 2

What role does contrast dye play in a Cardiac MRI?

Accepted Answer

A. Contrast dye enhances image clarity during a cardiac MRI by highlighting blood vessels and abnormal tissues, enabling the radiologist to detect blockages, inflammation, and other cardiac issues more accurately.

Question 3

How is a Cardiac MRI different from other heart imaging tests?

Accepted Answer

A cardiac MRI provides high-resolution images without radiation exposure. It offers a detailed visualization of soft tissues, improving the detection of both structural and functional heart abnormalities.There may be specific scenarios where MRI may not be the best imaging test for you. An alternative, more suitable test will be then preferred.

Question 4

Can lifestyle factors affect the results of a Cardiac MRI?

Accepted Answer

A. Yes, lifestyle factors such as high blood pressure, stress, and poor diet can influence heart function. Certain cardiac MRI procedures may require certain dietary restrictions prior to the test. The radiologist will inform you regarding this prior to the procedure.

Question 5

What can I expect during the Cardiac MRI procedure?

Accepted Answer

You may be asked to arrive early and change into a hospital gown, removing all metal objects and electronics.

You will fill out a safety form, and a nurse may check your vital signs.

ECG leads will be placed on your chest to monitor your heart’s rhythm; a small area may be shaved if needed.

An IV line/cannula may be placed in your arm for injection of contrast dye.

During a cardiac MRI, you will lie on a table inside a cylindrical scanner. The procedure includes brief periods of breath-holding and several short scans to capture multiple views of your heart.

You may be injected certain contrast dyes or other agents such as required. This will be discussed in detail before your procedure.

The scan usually takes 30–90 minutes.

The machine makes loud tapping or thumping sounds; earplugs or headphones are provided to reduce noise.

You may be provided with a bell in hand to help communicate with the technologist performing the scan.

Question 6

Can children undergo cardiac MRI?

Accepted Answer

Yes, children can undergo cardiac MRI. The procedure is safe and does not involve radiation.

Most children older than eight years can complete the scan without sedation if they can stay still, sometimes with the help of cartoon or music.

Younger children or those unable to remain still may require sedation or general anaesthesia, and this decision is made carefully by the radiology team after discussion with the anaesthetist and your primary referring doctor.
