yeah, i had been in the closed bore MRi before, and did not bother me. but i am of the thinking that the one i had this one time, (where i too kept pressing that button) was a smaller diameter..??? i mean jeez, that bore was IN MY face like i never remembered. and yeah, i freaked out like crazy....!!!!!! from now on, it's open MRI or no MRI.... i highly suspect that sometime after this upcoming operation, there will be at least one more MRI, and if i still need yet another operation on top of this one..??? more MRI's i surmise will be ordered.
