PET stands for

Explanation:
Positron Emission Tomography is a functional imaging method that uses radiotracers labeled with positron-emitting isotopes to visualize metabolic activity in tissues. When these isotopes decay, positrons are emitted and quickly annihilate with electrons, producing pairs of gamma photons detected by the scanner in coincidence. This allows the reconstruction of images that reflect biochemical or metabolic processes, such as glucose uptake with FDG. The other phrasing choices don’t describe the actual technique: they imply different, nonstandard or incorrect types of emission tomography or use different particles, whereas PET specifically uses positron emission.
