Morphology
positron + emission + tomography
The term is fully compositional: it denotes a tomography (cross-sectional imaging) that uses the emission of positrons, so the overall meaning follows directly from 'positron' + 'emission' + 'tomography'. This is a regular noun-compound, not idiomatic, and the construction is mirrored in many languages, so a learner who knows the constituent words can infer the MWE's meaning.
Etymology
Positron emission tomography breaks into positron, emission, and tomography: tiny positive particles are 'sent out' and a scanner makes 'slice pictures' of the body, so doctors can see which parts are more active.
