abstract = {Positron emission tomography (PET) combined with magnetic
resonance (MR) is a rapidly expanding imaging modality. For
this application, the availability of radiotracers labelled
with positron emitters is a basic requirement. These
short-lived neutron deficient positron emitters are produced
at a cyclotron. In a cyclotron, charged particles are
accelerated up to energies enabling to overcome Coulomb
repulsion and induce nuclear reactions. The beam is
extracted to target systems containing stable isotopes. Due
to the bombardment, these stable isotopes are converted via
nuclear reactions into radionuclides. The positron emitters
are subsequently used for radiolabelling molecules to obtain
radiotracers for various applications. Usually
radiosyntheses are carried out in automated synthesis
modules. The relatively short physical half-life of the
positron emitters in use requires fast and efficient
radiolabelling strategies that have been optimised for the
most common radiopharmaceuticals in order to facilitate
robust tracer production in sufficient activity amounts.
Beside the PET alone approach, emerging methods deal with
simultaneous PET-MR imaging to combine the high sensitivity
of PET with the high resolution of MR. One possibility to
exploit the synergy of both techniques is the combination of
clinically established paramagnetic contrast agents and
radiopharmaceuticals. This method was studied in several
preclinical and clinical studies. A much more elegant
possibility is the introduction of both modalities in one
single, bimodal contrast and positron-emitting probe. Thus
far, this technique was only tested in preclinical set-ups.},
