The benefits and challenges in creating a system combining pinhole SPECT and MRI are explored. By using a field-cycled MRI system operating at low readout field strength, a number of concerns, such as susceptibility-related field perturbations, are alleviated. Though mutually combative, these two imaging modalities are very useful for a combination of structural and functional imaging. The system we are designing is geared towards dual-modality imaging of small animals.
