For what purpose is FDG (18F-Fluorodeoxy glucose) primarily used?

Visualizing metabolic functions

What is the primary reason that PET and SPECT use radioactive materials that emit γ radiation?

To enhance the penetration of the radiation through body tissues

Why are PET and SPECT referred to as TRACER methods?

Because they utilize pharmacologically insignificant amounts of materials
