Simultaneous small animal PET/MR allows the study of functional processes on multiple levels. Here we present a comparison between simultaneous activation as well as resting state fMRI and PET in rats. Additional activated components of brain networks are found in PET, not present in fMRI. The data show complementarities of both techniques in respect to activation as well as default mode network imaging in the brain.
