Sorry didn't mean t duplicate answers. For some reason Rainy's response did not show up until after I posted.
Check around local hospitals and imaging centers and see if anyone has an open MRI. The machine in more like a CT scanner and you don't have to go in a tube. Good luck, hope your area has one.
Some imaging centers offer open field or high field MRI... Or you could take some medicine instructed by your doctor to keep you clam prior to MRI time. Speak with you doctor about other options. Hope everything goes well...
