Thank you for this - have seen this fog mentioned and will research. Our first PET was a 68Ga, supposed to have been one of 3 machines in the world. The 2nd was psma pet/ct at Mayo, which I believe is next month also. We have not had the choline eithe, which I understand can show things that don’t light on others or are obscured by the PSMA uptake say in the bladder.
