It's pretty recent, but I see no reason something like this couldn't be iterated on? https://hyperfine.io/swoop/overview

I came to mention the same device

Even without superconductors, advances in permanent magnets make some innovation practical. Here's an article about a portable MRI that sells for $250,000[1]

Swoop is 5 gauss which is 0.0005 tesla. Compare that with my last MRI which was 3.0 tesla. It seems be used for some kind of brain imaging, neuroactivity, etc. but it won't be replacing regular MRI machines. HST magnets will get you 6 tesla MRIs in the next decade or two.
