Would you treat a small focus of PET/Axumin uptake just below prior field of salvage prostate bed radiation just below a vesico-urethral anastomoses?

First, I assume there is a PSA recurrence and the patient has no evidence of disease outside of that one nodule.

I would first look at where the inferior edge of the initial post-prostatectomy field ends. The RTOG consensus guidelines recommend the inferior edge of the CTV to be 8-12 mm below the ve...

I would be interested to hear if anyone has seen urinary leakage from the vesicourethral anastomosis show similar signal on Axumin or PSMA PETs.
