First brain MRI,any tips?

[Soccermom]

Hi folks!
I've been having heachaches and neck pain and am scheduled for brain/head (not sure how to refer to the MRI) MRI on Thursday mornimg. I didnt get a chance to speak w Nurse (inventory at work) so i'll ask you guys.....is a brain MRI similar to a thoracic MRI. It is done with contrast...will I need muscle relaxers so I can remain still (lying on back KILLS my neck)? I know,I know ...I need to call my Doc....but in the meantime any suggestions? Its at 7:30 AM and I have to be at work at 10:00...any chance I will make it?

Thanks in advance!
