¹⁸F still wins: even though ⁶⁴Cu’s positron energy is similar, ¹⁸F produces tighter resolution due to shorter positron range and less gamma noise.⁶⁴Cu images are still good, but slightly more diffuse than ¹⁸F.

So it seems there may be another benefit? Table above is from ChatGPT, along with the summary. So does this defuse the CU64 threat?
