Oops.
Sorry...
I forgot to explain completely how the use of FDG (flourodeoxyglucose) liberates gamma-rays.
PET = Positron Emission TomographyThe two particles that are liberated upon the cell's metabolizing a FDG molecule instead of a normal glucose molecule are:
1. Electrons = Matter
2. Positrons = Antimatter (Positively charged electrons)
When these two particles collide, both are annihilated. They are converted into pure energy, in this case, in the form of gamma-rays. The rays are detected, measured, and rendered as an image.

Again:
1. A typical rendering of comparative PET scans in depression:
2. Fluordeoxyglucose (FDG)https://en.wikipedia.org/wiki/Fluorodeoxyglucose_(18F)
-------------
PET scans are not limited to using FDG. There are a plethora of other radio-labelled substances used for imaging various biological processes.
Enjoy...
