MRI Tech that can hopefully give you some helpful advice:
1. Wear comfortable clothing the day of your test, nothing with zippers or
metal. This includes your bra, wear a sports bra. You will probably be
most comfortable in pants with an elastic band and a t-shirt. Do wear
socks in case your feet get cold.
2. Leave all jewelry at home.
3. If you take a xanax, valium, or ativan pill, take it 1 hour before your test
time. Someone will need to drive you to and from the testing facility.
4. No prep the day of the test, you should be able to eat or drink as you
wish, especially if you are taking meds, you need to eat something.
5. You will be asked to fill out some forms once you get there so be sure to
know your surgical history.
The MRI machine can be intimidating but just remember that nothing is going to close up on you. The only part that can move is the table you will be lying on and it will go in or out based on where the images are being taken. You will be given earplugs or music to help with the noise (yes, the machines are very loud!) and if you tell the tech that you are claustrophobic, they will give you a handheld device that will trigger an alarm if you decide you can't stay in the machine and they will pull you right out. You can also request to have your eyes covered up so you don't see the machine and yes, this helps a great deal!
The contrast is easy breezy. Somewhere in the middle to the end of the test, the tech will bring you out and give you an injection but you will not get warm all over your body (that's CT!). You may taste a metallic taste in your mouth and some people report that they feel nauseous but it passes quickly.
Each scan lasts approximately 20-30 minutes on a closed MRI and you will be asked to hold perfectly still. ANY movement from any part of your body can show up on the scan and "blur" the images. Try not to cough during the test.
That's all I can think of right now. If you have any questions, I will try to answer them for you the best I can.
