Simultaneous PET-MRI imaging is an exciting new technology for quantitative assessment of whole-joint disease in osteoarthritis (OA). Attenuation correction (AC) for MRI hardware is a challenge for PET quantification in hybrid PET-MRI systems. In this work, we tested a new, lightweight, screen-printed, flexible, 12-channel phased-array MR coil which reduces PET photon attenuation from MR hardware in a PET phantom to below 3%, potentially removing the need to correct for it. Further, the close proximity of coil elements to the knee show promise for high SNR MRI knee imaging.
