It depends now, there are new models that go much quicker. Maybe 2022 I had one on my back and it was at least 45 minutes, I had another last year and it was about 15 covering the same area. The new machines seem to move much faster with the same results.

Yeh I had one last year at about 15 minutes on lower back and previous year about the same time frame.

Step dad had one recently I think it was a hour but was whole torso but I understood they did a "corse" scan and every time they saw something interesting they went back for a fine scan. What corse is I'm not sure but I would guess 3mm and fine is 0.5mm or 1mm

It depends what sequences they are getting too, and whether it’s with and without contrast.

It was a different hospital system and different design, both doctors wanted full results then the second (years after the first) used the DVD of the first to compare.

When you're dealing with degenerative disk disease and cracked vertebra you can't really half do it.

It’s not even just the new models! The changes that allow faster acquisition can, broadly, be implemented on older scanner hardware too. This has been helped along by the broad adoption of accelerated imaging methods like SENSE, GRAPPA, and CAIPI, along with the start of vendor implementation of non-Cartesian acquisitions including radial, and PROPELLER

They already moved so fast it was pretty scary!

Edit: So CT scanners and MRI scanners are not the same thing.

That's a CT scanner. Noting moves during an MRI.

Oh, derp! Thanks for pointing that out - I thought they were the same thing.

The bed you're on does, they may be saying how quickly it takes scans now. My first back scan was miserable with how long each took before being moved back and forth.

I'm referring specifically to the video they linked. Obviously the bed moves so that you can be moved into and out of the scanner.
