Cardiac MRI Scans
What is a Cardiac MRI?
A Cardiac MRI (Magnetic Resonance Imaging) uses strong magnetic fields and radio waves to create detailed images of the heart and surrounding blood vessels. Unlike X-rays or CT scans, it doesn’t use radiation, making it a safer option for children.
When is it Needed?
- To evaluate heart structure and function in detail.
- To monitor congenital heart defects.
- To check for scarring, damage, or other heart issues after surgery or illness.
- To assess specific heart conditions like cardiomyopathies or pericarditis.
Why Choose Cardiac MRI for Children?
- Safe: No radiation exposure.
- Detailed: Provides high-quality images of the heart and blood vessels.
- Non-invasive: No incisions or surgical procedures.
How to Prepare for a Cardiac MRI?
- Discuss with the Doctor: Inform your doctor about any medical conditions, surgeries, or implanted devices (e.g., pacemakers).
- Remove Metal Items: Your child must remove jewellery, glasses, or clothing with metal parts.
- Fasting: If a contrast dye will be used, your child may need to avoid food or drink for a few hours before the scan.
- Support for Anxiety: Let the staff know if your child feels nervous or claustrophobic. Sedatives or distractions, such as music or toys, may help.
What Happens During the MRI?
- Your child will lie still on a table that slides into the MRI machine.
- If needed, a contrast dye will be injected to enhance imaging.
- The machine makes loud noises, so earplugs or headphones may be provided.
- The procedure takes 30-90 minutes, during which the team monitors your child closely.
What to Expect Afterwards?
- Your child can usually go home and resume normal activities immediately.
- If contrast dye was used, encourage hydration to flush it out.
- Results are typically ready in a few days; your doctor will explain the findings.
