Morphology
PET = positron + emission + tomography (opaque) = P + E + T
If a learner knows the full phrase 'positron emission tomography', the acronym formation from initials is straightforward, but the abbreviated form itself is not self-explanatory.
Etymology
PET comes from the first letters of positron emission tomography. A positron is a tiny particle, emission means 'sending out', and tomography means making 'slice' pictures. So a PET scan shows active parts of the body by catching particles they send out and turning them into images.
