Challenges in Acquiring Clinical Simultaneous SPECT-MRI on a PET-MRI Scanner

The INSERT is the world’s first clinical SPECT-MRI brain imaging system based on scintillation detectors with a silicon photomultiplier readout. Here, we demonstrate its use within MRI environment for time. Using standard transmit-receive head coil, and an appropriate selection of custom sequence (GRE), overcome mutual interference. bulky 50kg tungsten collimator introduce magnetic field inhomogeneity. Due to specific MRI-compatible design, inhomogeneity compensated by shimming, leading simultaneous acquisition. We process SPECT data acquired alongside evaluate performance impact MRI. Finally, present set acquisitions, demonstrating multimodal capabilities, albeit limited sequence.
