Positron Emission Mammography (PEM) is a dedicated breast imaging systems performing breast imaging under gentle compression. PEM exhibited a higher spatial resolution than PET due to the good immobilization of the breast and its small interdetector distance. However, its data acquisition scheme results in a poor axial spatial resolution. In this study, we introduce a new combined PEM/MRI system taking advantage of the high resolution soft-tissue contrast provided by MRI and the best signal to noise ratio (SNR) due to efficient count collection configuration of PEM. The performance of the system is validated on a breast phantom.
