A bone scan makes sense when you're on ADT and your PSA is very low — a PSMA-PET scan probably wouldn't work in that situation.

I've had at least 3 bone scans since my diagnosis in 2021. They injected me with a tracer, then I came back in a couple of hours for the actual scan. The challenge is that you have to stay very still for 30–45 min, so they might wrap something around your ankles and even your arms, lightly, to make it easier to hold them in place.

Best of luck!
