We received the following question regarding tracer details: "Could you specify exactly what tracers you are using? For example, is it F-18-PSMA-1007, F-18-PSMA-DCFPyL, …? The same applies to Ga-68-PSMA… Is it Ga-68-PSMA-11, Ga-68-PSMA-I&T, …?"

In alignment with the data extraction protocols established for the autoPET I and II challenge, we did not explicitly extract tracer information at this granular level. The objective of this challenge is to develop models capable of functioning independently of such detailed metadata. We appreciate your understanding in this matter.
