WHAT IS AN MRI?

The exam itself is painless. You will lie on a table that moves into the MRI scanner while your images are taken.
MRI SAFETY
Have Metal or a Medical Device in Your Body? Tell Us Before Your Appointment.
MRI uses a very strong magnet. We need to know about anything implanted in your body before your exam.
If you have an implanted device, call our Radiology Department at 505-822-3803 before your appointment.
If you have a device ID card, please have it available when you call. The information on the card helps us make sure you can safely have an MRI.
If you no longer have the card, tell us where the device was implanted if you know.
Please don't wait until the day of your MRI to tell us. We may need time to research your device before your exam.
HOW TO PREPARE
Getting Ready for Your MRI
NERVOUS ABOUT YOUR MRI?
Tell Us. We Can Help You Prepare.
It's okay to be nervous about being inside the MRI scanner.
If you think you may need medicine to help you relax, contact your doctor before your appointment.
Bring the medicine with you rather than taking it before you arrive unless you have been instructed otherwise.
If you take medicine to help you relax, you must have someone drive you home.
