Hi Steve,
Welcome to OCF. I can not articulate the technical merits of either other than to say a PET/CT is both a CT and a PET scan, two scans. So I would venture to say having both types of scans to review the progress is better in the hands of those who know how to read each.

My understanding of the CT done during PET/CT is not as clear and useful as the standalone CT. Someone mentioned the reason why but that eludes me now.

Best for your scans. I am due end of this month too for first set.
