In most cases, MRIs don’t require special preparation. But, before your exam, you will put on a patient gown and remove all items that contain metal. Please tell your MRI technologist—the person performing your test—if you have a metal implant of any kind.
Your scan may require contrast (dye). If so, you’ll get an IV catheter to administer the dye. You may feel a cooling sensation. Contrast doesn’t have side effects, and your body will naturally eliminate it after the test.
The MRI machine is shaped like a large tunnel or tube. You will lie on a padded exam table that slowly moves into the machine for the scan. You need to stay very still during this time.
MRI machines are noisy, so we will give you earplugs or headphones to protect your hearing. The MRI technologist may provide instructions, such as asking you to hold your breath briefly.
Most MRIs last between 45 and 60 minutes.
If you feel nervous about tight spaces, let your doctor know ahead of time. They may give you medicine to help you feel more relaxed.
A radiologist will review your scan images and write a report for your doctor to discuss with you.
