Novel hybrid systems such as PET/MR can simultaneously provide metabolical and anatomical information in breast cancer imaging. Here we present design and implementation of a 16-channel breast RF coil optimized for simultaneous PET/MR (3T) systems. In phantom studies we found that the MR performance of the PET/MR coil was comparable to MR-only coils. Accurate PET quantification could be achieved with the PET/MR breast coil in the PET FOV by implementing a CT-based template-attenuation correction (AC) map of the coil to be combined with the MR-acquired phantom-AC map.
