I had a "Nuclear Medicine whole body bone scan" in February. My urologist also ordered a CT scan. I expressed a concern that I might be exposed to too much radiation if I had CT so soon; I was assured it was safe to have both. Thanks Jeff; it's reassuring to know that the scans I went through is the equivalent of the newer "PET scan" -- I have been wondering for a long time why my urologist didn't order that. I guess PET scans are not yet widely done in my area.
@lag Simulation was actually done after my gold seeds implant -- the metallic markers to make the prostate radiation more precise. Each radiation treatment session is preceded by a mini-CT scan, according to my care team, so they can make adjustments as compared to the simulation images. I completed my SBRT in April.
