I wish I could help. I did fall asleep during a CT in the 1990s. My sinus surgeon said it was the best image he had ever seen due to the limited movement during the scan.
I’m not sure if there is a limited image with a standup MRI, but it seems if you are paying for it then your physician should let you pick the MRI you want as long as it’s within your coverage and will do the job, diagnostically. Your doctor of course, wants to have you use the MRI that’s financially associated with his or her institution, but that doesn’t mean it’s the only choice available. I imagine it would be on you to look up which imaging services are covered by your insurance, and have your physician order it be done at the place of your choice.
But keep in mind the purpose of an MRI is to give your physician the best idea of what is going on. When MDA was still looking for metastasized cancer in me, my physician specifically asked that I be scanned with the brand new Siemens MRI, which he said gave a better image then the slightly older MRIs that was the backbone of scanning at MDA. In my case, the scan was to find small cancers that chemo hadn’t killed, and so I had no problem with a longer wait until that particular machine was available.
That is my long-winded way of saying that you need to pick the MRI alternative that gives you the best image. Period. So gummy up if you have to.
