It was a 1.5T machine. I have read that spinal lesions can be difficult to detect at that strength. I have no brain lesions, just the cervical spine and optic nerves that, as I said, took a very long time to show up.

I am seeing another neuro for a second opinion in February, so I suppose I might consider requesting a scan on a 3T machine. I don't think I would be able to get that bulk-billed though, so would probably be several hundred out of pocket. Worth it if I can get some answers though.
