The integration of small-bore MRI and SPECT systems for back-to-back multimodality imaging has previously been limited to magnetic field strengths of only 0.1 T. Through the use of CZT-based nuclear radiation detectors, we have integrated SPECT with a 7 T MRI system for small-animal imaging. Co-registered MR and SPECT images of a mouse injected with 99mTc were acquired using this combined system.
