Outside of PSMA scans what tests are important to new patients?

Yes, PSMA can show where advanced prostate cancer is located. However, at lower PSAs, PSMA PET scans are less sensitive to prostate cancer (see attached chart).
Also, about 15% of prostate cancers are PSMA negative (or PSMA naive) such that PSMA PET will often miss them even though you know something is wrong due to the increasing PSA.
That’s where other types of PET scans that aren’t reliant on PSMA (like Axumin PET scans) may be helpful. Always consider the full set of tests/calculations that are available.

great advise . Also I think in Canada they say you need over at least o.45 or so for a PSMA to pick up anything . Maybe even higher . PSMA scans have a minimum detect level , depending on equipment . There is a risk at times letting it go that high w/o radiation , post surgery . I also had a Contrast MRI and a Pet scan prior to surgery 3 years ago . God Bless to you all !
