Question

Question Posted 07/18/24:
I read from ADNI3 PET imaging protocol that you collect venous blood samples throughout scan for generating venous input function, but I couldn’t locate where this data is on IDA. Could you please advise?
Response posted 07/18/24 by Robert Koeppe:
Collecting venous samples was done in a subset of subjects only during ADNI-1. That hasn't been done in ADNI-2 or since. I guess that part of the original manual never got removed. I apologize for the confusion.
