PSMA PET Scans...some interesting info

Thanks for sharing that. Here in Ontario, PSMA-PET hasn't become standard yet: it is available, but it's not automatic, and tends to be reserved for complex or exceptional cases.

When I asked my radiation oncologist about it, he said "The problem is that we don't know what to do with the results." I see that the article is saying the same thing: as far as they can tell so far (it's very early days), much of the stuff that lights up on PSMA-PET but not CT and/or bone scans never develops into anything serious, so what do you do with that extra info?

"Here's somewhere a serious tumour might develop some day … maybe … but probably (?) not … so, um …" 😕

@northoftheborder A confusing bit of information isn't it? How do we actively surveil metastases if they might not require immediate treatment?

@northoftheborder With PSMA PET scans there are different levels of “lighting up.” The level of “lighting up” is reported in a SUVmax score. The lower the SUVmax score, the less aggressive the prostate cancer; the higher the SUVmax score, the more aggressive the prostate cancer.
