It was just yesterday I was reading about this, and I was left with the distinct impression that 10T existed, though they were uncommon. I can't cite my source, though, as I don't remember where I was reading this, so maybe I'm just crazy.
Well, I *am* crazy, and I have MRI proof of brain damage
, but that's beside the point.
Anyway, does anyone think/know if it's worth the minor extra effort to find higher resolution machines or not? What about this 'open bore' design stuff? Does that actually improve image quality?
