Abstract

The goal of this conference record is to present the experiments conducted to evaluate a magnetic resonance (MR) compatible, simultaneous SPECT-MR insert for small animal (SA) imaging that we have been working on for the last three years. As previously demonstrated, the insert consists of 5 rings of 19 MR compatible CZT detectors connected seamlessly. A multi-pinhole (MPH) collimator with focused pinholes was built using a plastic shell filled with high-density coated tungsten powder and fitted with solid tungsten pinhole inserts. To acquire SPECT and MR data simultaneously, a shielded transmit/receive radio frequency (RF) coil is inserted into the MPH collimator. The insert was evaluated as a standalone SA SPECT system using both a hot-rod resolution phantom (HR-RP) experiment and SA imaging studies. Furthermore, simultaneous SPECT-MR phantom and SA imaging experiments were conducted by …
