I went through the same thing. I had an 8 month wait list to get my MRI.

Other than the cancellation list, the only suggestion I can make is going the private route. I belive it is usally in the $1,500 range for a private MRI. If you do go the private route make sure you talk to the neuro first to get the specs they want for the MRI. You don't want to spend the money and then find out it wasn't what the doctors were looking for!
