These are two totally different tests. The isotope that takes up in the bones will illuminate in the bone scan. CT shows the uptake in the soft tissues. He is just verifying that the uptake in the bone IS arthritis. I believe what the doctor saw was enough uptake in the bones to be unsatisfied with the results. The PSA numbers do not suggest he has such wide spread PC. I just believe he was unable to use the bonescan to any real value. Could it be something more? Yes. But the CT should show some activity as well. I still believe that he has local recurrance. The 0.3 suggest slight spread, and that is usually in the prostate bed. Have you ever had anybody tell you to stay positive?
