Simultaneous, small animal PET/MR imaging has a great potential in preclinical research. Differences between MR contrast agent enhancement and PET uptake were observed in a brain tumor mouse model. The influence of a Choline-PET tracer on MR spectroscopy was evaluated. Simultaneous [15O]Water PET and ASL-MR perfusion measurements were performed and compared.
