While we already reported indexes of the performance of one of the first commercially available SiPM-based MR-compatible PET Insert, no NEMA testing has been reported until now. Moreover the NEMA protocol for evaluating the performance of preclinical PET scanner, do not cover the integration and potential interference between PET and MRI. We hereby propose and report an extended NEMA protocol demonstrating the performance of the MRI (Biospec USR 70/30) with and without the presence of the PET Insert as well as the performance of the PET with simultaneous MRI acquisition.
