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.
