Summary
A cardiac MRI is a safe and painless imaging test that helps doctors see detailed pictures of your heart. This handout provides easy-to-follow steps to prepare for your appointment, ensuring accurate results and your comfort during the procedure.
What Is This & Why It Matters
A cardiac MRI is a special type of scan that creates detailed images of your heart. It's used to help doctors understand how your heart is functioning and to diagnose any potential issues. Preparing properly ensures the images are clear and the procedure is safe for you. This process involves removing metal objects, following specific instructions, and understanding what to expect during the scan.
What You Should Do
- Remove all metal items, including jewelry, watches, and piercings, before the scan.
- Wear comfortable, metal-free clothing such as sweatpants or a cotton shirt.
- Arrive at the imaging center at least 30 minutes before your appointment for check-in and preparation.
- Inform the technician if you have any implants or medical devices in your body.
- Practice holding your breath for short periods as this may be required during the scan.
- Bring a list of medications you currently take to discuss with the medical team.
- Stay relaxed during the procedure; you can talk to the technician through a microphone if needed.
