Simultaneous acquisition of MRI and PET shows great promise for disease characterization as it enables concurrent collection of complementary molecular and anatomical information. To overcome the limited dissemination of integrated PET/MRI systems due to the high cost, we have developed an RF-penetrable PET insert integrated with custom RF coils that can be inserted into any existing MRI system for simultaneous PET/MRI acquisition. The RF-penetrable PET/RF-receiver insert enables the use of the built-in body coil for more uniform transmit RF field, fast acquisition using parallel imaging, and high SNR MR and PET images.
