Yes, Thrifty! Thanks for reminding me of that study. I ran across it a few months ago and sent it to Dr. Kelly, hoping they could make some sense of it.

I just really would like to understand if this test is something done on the individual patient level, or if it's some sort of general test where they measure occupancy on an experimental level to see how long before it declines, etc? Still hoping someone can explain it to me.
