Short summary
Transport processes can be observed with input–output experiments, disregarding the impact of heterogeneities, or they can be modelled, based on structural images. In contrast, positron emission tomography (PET) directly yields the spatio-temporal distribution of tracer concentration. PET benefits from its molecular sensitivity together with a reasonable resolution. We illustrate its use with examples of process monitoring of advection and diffusion processes, and we discuss benefits and limits.
