MRI lasted about 45 minutes in the tube. Took a chunk of my afternoon though to get up there and wait and such. Don't get me wrong, they were efficient and very kind, no complaints of any kind. There is just a lot logistically to do: clothing, get the IV line ran (for contrast), paperwork, etc.
I'm no expert at reading the films so I cannot comment on what they look like. I'll call to get a copy of the report in a few days / a week. I didn't get by the Dr.'s office to drop off the last of the Avonex paperwork today so I'll do that tomorrow.
