    摘要： A Positron Emission Tomography (PET″) insert for use with a Magnetic Resonance Imaging (“MRI”) scanning device, the PET insert including a plurality of photodetector modules provided adjacent each other in an array, the plurality of photodetector modules configured for placement adjacent a body of a patient and sized to be received in a magnetic bore of the MRI scanning device with the patient, the photodetector modules providing detection of gamma annihilation photons, and a Radio Frequency (“RF”) coil provided between the patient and the plurality of photodetector modules. Each of the plurality of photodetector modules includes a pixelated scintillator array provided for alignment adjacent the patient's body, and a shielding block including silicon photomultiplier pads and passive electronic circuitry only.
