Actually, the PSMA PET scan has a hard time seeing metastasis that are smaller than 2 1/2 mm. Micro metastasis are a problem for sure.
I was at the UCSF conference today and asked them about it and they said yes 2 mm is hard and even bigger can be hard depending on the case. The radiation oncologist gave a few different presentations and showed a number of slides with people that had metastasis that couldn’t really be noticed without the PET scan.

From what I have read and others have stated the PMSA PET scan is better that an MRI at picking up micro metastatic cancer. A lot of times the PSA will rise before the PET scan can see it.
