I haven't looked, but I'd surprised if we could do much better than 1/8th of
a mm^3. Even if it was as good as MRI spectroscopy, it's still a far cry from
TEM's ~nm resolution.

You can't. Sensitivity is limited, and so is field strength. We've had quite
a few discussions in the past, you can find some recent ones on
http://www.google.com/search?q=site%3Aleitl.org+resolution&hl=en&num=100&btnG=Google+Search

Never, of course. It's either invasive, or destructive. There is no other
way.
