Today, non-invasive imaging techniques are significantly contributing to the understanding of molecular processes in vivo. Positron emission tomography (PET) is a scintigraphic medical imaging modality that uses radiolabelled molecules (tracers), provides quantitative tomographic images and allows non-invasive assessment of the biodistribution of radioactive substances in vivo. The assessment of pathological glucose metabolism is the clinically best-established application of PET today; however, a multitude of different tracers are available to assess diverse physiological processes. The growing interest in pre-clinical imaging studies, in biological and medical basic research, as well as in pharmaceutical research, has fostered the recent growth in small-animal PET. Small-animal PET can be applied to enable the transfer from molecular findings in vitro to in vivo applications in humans, from bench to bed side.
