Here, wed like to report relevant influences of novel
SiPM-based PET scanner on MR images at ultra-high
magnetic field. Several MR image including FSE, SE, GRE,
3D SPGR, and EPI were evaluated with a 7-T MRI scanner
and 35-mm-inner-diameter mouse body transceiver coil.
The experimental results show that the PET insert unit
affects only minor effect on MR images that can be
ensured for preclinical evaluation. It was also proved
that to perform multi-functional study of PET and
functional MRI using our PET insert unit is possible.
