Field-cycled MRI employs two actively controlled resistive magnets to polarize and subsequently image an object, the benefits of which include an increase in T1 dispersion contrast and a reduction in susceptibility artifacts. Due to the versatility in design of the main resistive magnets, an allotment of space can be made for the integration of a PET ring or SPECT camera. The construction of the main magnets for a dual-modality, field-cycled MRI/PET system is presented.
