We have developed a MRI compatible PET tomograph for use inside a 9.4 T microMRI scanner. This synergistic integration resulted in simultaneous acquisition of MR and PET imaging of rodents with minimal mutual interference between the two systems. New MRI coils have been built that fit inside the PET detector and obtain high quality MR images. Simultaneous MR and PET images of a rat striata phantom, rat brain and gated mouse cardiac images have been acquired, providing the flexibility to perform both rat brain and mouse cardiac studies using the same PET detector inside MRI.
