F-Dopa (AA PET)

[Gfunk6]

I recently learned about the utility of AA-PET for brain to help distinguish between radiation necrosis and tumor recurrence. Just curious if any of you use this, and if so, who is the vendor.

Would love to see if something useful opened up in this space. It is a struggle...in my area some neuro rads guys like MR perfusion or MR spec, some don't. We have a robust CNS program (for a community regional cancer center) with well trained neurosurgeron and neuro rads/neuro IR guys and we struggle with this diagnosis on the imaging side. Even with those images I still get very equiovocal reads and don't have confidence in them.

I switched to MR Perfusion from SPECT, as I don't think I had anything other than a hedge read with SPECT. I've had some more definitive calls with Perfusion, but it's still nowhere near where it needs to be.

I'll ping my neuro-oncs and see if they've heard of AA-PET.
