Sometimes the scans don’t line up well because of differences in rectal and bladder fullness- any tips to optimize the fusion?

I ask this because I am seeing more and more patients who have had surgery despite presenting with high risk disease.

I know many do not treat the pelvis at all, but for those who do, what criteria do you use? Risk? Gleason? PSA? T stage?

And should special precautions be taken (such as dose reduction, prophylactic symptom management, etc)?
