Types of bone scans?

My shooting nerve back pain is gone for now. Xray was clear for "bone shifts" in my spine - ruling that out as the cause. I asked doc if no mets showing on xray meant they were gone. He said you cant say that for sure. Anyway, my PSA is now 0.1 as of last test - excellent. MO mentioned he would send me for more sensitive bone scan than my original to get a new baseline for how chemo is working. He said it was "floro.." something. I didnt ask him to repeat since i tjought i could google it. But seems i cant. Any clue what type of scan this would be?

  • Based on your report I'd guess he is planning a PET scan. The radioactive tracer is an isotope of Fluoride (FL18). It highlights areas of abnormal cellular activity (aka, growth). I've had a couple for a different cancer (not PCa) which was all over my body. Simple, just like c a CT scan with a radioactive twist. I hope that's it for you; mine was a very useful and effective tool.

  • 0.1 is GOOD!

  • It could be a Choline trace or Axium tracer both are PET based scans that highlight PCa cell activity in organs or bones the cells glow when the tracer is present. Good luck :)

  • There are newer scans that allegedly can do better than the PET Fluoride (FL18). There are several PET choline scans. There is a PSMA PET scan. They all need higher PSA levels though.

    My Oncologist is intentionally letting my PSA climb to 2+ in order to do a PSMA PET scan.

    from Jelle Barentsz (considered world authority on Prostate Scans) :

    "PSMA PET-CT is the best, second is Fluciclovine PET, third is 11C Choline PET.

    Most probably Fluciclovine PET will be not as good as PSMA, as it is an amino acid like 11C Choline.

    For small LN Combidex is the best of all."
