On May 22, jt inquired:

Without knowing jt's details, it's difficult to guess.

But, since the communication was not via phone, I'd suppose that it's
probably something else that the medic suspects and wishes to verify.

Regards,

Sure, it could be something else.  What happens in the bone
scan is that "hot spots" show up.  A "hot spot" is anywhere
that there is increased metabolism or uptake of the radioactive
isotope that was injected for the scan.  So, if you had a wisdom
tooth removed or had a healing bone fracture or you have
osteoarthritis, for example, that's all going to show up on a
bone scan as "hot spots."  No way to tell from those scans if
they are cancer or not.  If the doc wants to x-ray then  it may
mean that the scans showed something going on in some of
those places that the doc wants more information about.

Sorry, jt, but I know nothing of your history.  How old are you?  When did
you find you had PCa?  How was it removed?  What have your PSA results been?
Etc., etc.

Based on absolutely nothing else, I'd say there is a significant possibility
that you have arthritis.  When I had a bone scan my hands, feet and back lit
up like a Christmas tree.  And I was only 48 at the time.

There are several possibilities.  No use in assuming the worst.

I'm a radiologist who reads bone scans.  How old are you?
The fact that only joints need to be x-rayed says to me that this is
probably just arthritis.
Prostate metastases tend to go to the "axial" skeleton...meaning the
spine, pelvis, skull, and proximal femurs.  Without knowing the
situation,  I would speculate that the "doctor" is looking to do some
extra billable imaging by filming any area that showed up "hot" on your
scan.  The distribution you describe is highly unlikely to represent
metatstatic disease.
Good luck, CPW
