The most recently introduced PET/MRI systems, like those which include silicon photomultiplier (SiPM) detectors and time of flight (TOF) capabilities, have higher sensitivity levels compared to conventional PET/CT devices, but comparable to the latest generation PET/CT systems. Considering new-generation PET/CT systems, the cost difference between PET/MRI and PET/CT is not as significant. The percentage of MRI-only scans performed using the PET/MRI camera system, and the clinical indications for PET/MRI were gathered. The upcoming PET/MRI generation is set to feature several hardware and software advancements that will benefit image quality and speed-up PET/MRI procedures, particularly addressing the traditionally time-consuming MRI component.
