There is a new combination of 2 powerful and excellent diagnostic tools: The PET, which shows metabolic and functional processes, and the MRI, which has a perfect soft tissue contrast without ionizing radiation. They are put together to acquire pictures simultaneously. This is a big time saver for a patient getting a complete diagnostical examination. For the PET examination, radioactive pharmaceuticals like 18F-FDG, 11C-methionine, 68Ga-DOTATOC, and 18F-choline are injected. After a standardized time these radiopharmaceuticals are at their destined place and measured with the PET. At the same time the MRI examination takes place, without interrupting and disturbing the PET. The whole body examination takes about 1 h in generally 5 steps to cover the field of view from the upper legs up to the head. After the PET and the anatomical MRI both datasets are fused and then it is very well recognizable where the enrichment takes place. The PET-MRI is also a new and very good invention for the reduction of radiation exposure on children, who initially get a PET-CT. This is also very important for follow-up examinations. The PET-MRI will not detach the PET-CT, because many patients cannot get a MRI examination. In case of a cardiac pacemaker or claustrophobia the MRI is unsubscripted. But it is nice to be able to find additional diseases which cannot be exhibited in the PET-CT. Furthermore it helps the patient, when diseases are identified early, so therapy can be started in time.

Abstract
Die Gerätekombination aus MRT und PET ist neu. Erstmalig in der Hybridbildgebung ermöglicht das PET-MRT eine deutlich strahlensparende Untersuchung. Es erlaubt die zeitgleiche Erfassung von Morphologie und Funktion. Insbesondere die Onkologie profitiert von der anatomischen Zuordnung von tumorspezifischen Stoffwechselprozessen. Das PET visualisiert diese Stoffwechselprozesse, wohingegen das MRT die anatomische Lage detailgenau zuordnet.
