I am not jcf58 obviously, but it is Dr Woodrum interventional radiology who does Tulsa at Mayo, he did a lesion in my kidney (not with Tulsa obviously) a year before I had Tulsa on prostate as they only have had Tulsa for months and didn't even have it when I was at Mayo. Dr Scionti, Sarastoa FL did mine. Thing is Mayo is doing a study on Tulsa, they have parameters like 3+4 most likely in the protocol because that was the design of the study. The protocol was NOT meant to cover a wide range of people, so it is a simple study to quickly get to press and not be encumbered by wide ranging Gleason scores or other parameters that make a study harder to sort data. So you may or not qualify at Mayo because that protocol. I have been involved in research in past so I know how these things work sometimes. You will have to inquiry to be sure or not. Dr Scionti can still do Tulsa outside 3+4, he will take the temp up for long enough to cook a Turkey or Ham or 4+3.
