Our group has built the worlds first preclinical,
digital PET insert which is designed to be installed
inside a clinical 3T MRI system and makes use of digital
Silicon Photomultipliers. In this work, we investigate
the MR-compatibility of our PET detector in combination
with a 3T MRI system and performed a first animal
studies to demonstrate the imaging performance. This
comprehensive interaction investigation includes
interference studies between the PET detector and all
sub-systems of the MRI scanner. We found acceptable
level of MRI performance degradation with the PET system
operated and no relevant PET performance degradation
during normal imaging conditions.
