MRI is not an emergency technology. Most hospitals will outright refuse to do them for the vast majority of inpatient stays.
This technology will mostly end up in imaging centers, improving throughput.

Still, an ER MRI is wildly unlikely. “Possible evolving emergency” and “an hour in a tube where we can’t see you” don’t play well together. Any chance you’re confusing CT scan for MRI? Cause -that- we would do for a head trauma like 1000% of the time.
I think the combination of weird blood work + medical mystery + stabilized meant I got an MRI. wish they'd gotten to the bottom of it..
If you solve or alleviate those issues it becomes more attractive. There is a fair bit of research around potential trial benefits if the contrast provided for some emergency procedures already.
Ugh, I just wrote this long-ass post and lost it. Whatever, here's the short version:
Stroke is a clinical diagnosis, not a radiologic one.
CT will catch hemorrhages or large infarcts just fine. That's the important stuff: big infarcts cause big tissue damage. Tiny infarcts cause tiny tissue damage. MRI's superiority over CT is in that it catches smaller infarcts, and catches infarcts early. If I see a patient that screams "stroke" and the noncontrast CT is negative for hemorrhage, it's ischemic until proven otherwise. I don't need an MRI at the less than six hour stage and, while having one would be nice for malpractice reasons, whatever, I don't actually need one for your care. I may follow-up with an MRI if it's less certain that it's a stroke: tumors, infection, etc. that look like strokes. But, key - those aren't pressing, time-wise, the way a stroke is, if they look like a stroke ("look like" implies things about the nature of the underlying condition.)
After 6 hours we've passed the TPA stage and we're looking at clot removals. Here we need to know the exact territory of the infarct. If I'm bothering with imaging, yes, MRI/MRA, but that's not about finding the kind of stroke - it's about telling the interventionalist where to go.
The method that works where I didn't accidentally close the last tab associated with a particular renderer process (or, TL;DR, didn't close any tabs), is to promptly figure out which renderer process is behind the tab in question via chrome's task manager, quickly attach to it with gdb, then `generate-core-file (filename)`, and grep through the result for my text. (Usually `grep -aC100`.)
Alternatively, hibernating generally seems to always(?) save the disregarded bytes to disk (the associated memory regions immediately get used for something else, so they stay in in the pagemap); then I can reboot the machine, carefully prevent it from resuming, boot to Linux, mount the FS readonly as appropriate (since it was never unmounted cleanly), then go through the hibernation/swap image. (Bonus points for then resuming once you're done.) I recovered a family member's lost draft email this way once (TIL Gmail encodes emails in both HTML _and_ HTML-inside-JSON O.o).)
