The first fully interleaved hybrid images from a combined positron emission tomography (PET) and field-cycled MRI (FCMRI) system are presented. In FCMRI, it is possible to rapidly turn all magnetic fields off, enabling the use of conventional photomultiplier-tube-based PET detectors. PET data were acquired during MRI sequences in an interleaved manner with a period of several seconds.
