@clevelandguy It’s been reported that different tracers bear out better results - even some of the older ones.
I think Gallium is standard now?
Perhaps your RO can brainstorm this with you. Best,

Micrometastases of prostate cancer are very small clusters of cancer cells, typically defined as having a maximum diameter of 2 mm or less. These tiny deposits often escape detection on standard imaging scans (MRI or CT). While often under 2 mm, some clinical definitions in research contexts may refer to lesions up to 1 cm as "micrometastases" in lymph nodes.

Those are exactly what they cannot see when doing a PSMA Pet Scan.
