I need help answering a few simple questions:
Unwanted photons or "noise" can be reduced in nuclear medicine imaging by adjusting what?

How is the radiotracer for pet scanning selected?

The most common device used to produce nuclides for pet scanning?

Thanks

Adjust the energy window spectrum width or %. Reducing the E-window width will eliminate unwanted counts or noise.

Like any tracer in nuc med the organ or organ systems of interest determine the radiotracer. For example; Oncology primarily utilizes F-18. Cardiology primarily Rb82.
Additionally, the radiochemical determines the mode of action of all radiopharmaceuticals.

The most common device is a cyclotron. Many positron nuclei have a short half so some facilities have them onsite or very nearby.

Hope this helps.
