Given that this was published nearly a decade ago, I'd be very interested to see what the SOTA is today.

Between this and blipped-CAIPI in 2011, there hasn’t been much change from an acquisition perspective in the industry. Mostly everyone shifted to AI reconstruction, workflow improvements, and reducing helium use. Those are the low-hanging fruit. I’d be happy to be proven wrong but I don’t see any major breakthroughs coming from advanced math in the near future. ISMRM was this week though so maybe something came out of it.
