Although PET offers high spatial resolution and low radiation exposure, its use in newborns is limited. This study investigated the feasibility of cardiac PET imaging using the latest silicon photomultiplier (SiPM) PET technology in infants of extremely low birth weight (ELBW) using a phantom model. <b>Methods:</b> The study used a phantom model representing a 500-g ELBW infant with brain, cardiac, liver, and lung tissues. The cardiac tissue included a 3-mm-thick defect mimicking myocardial infarction. Organ tracer concentrations were calculated assuming <sup>18</sup>F-FDG myocardial viability scans and <sup>18</sup>F-flurpiridaz myocardial perfusion scans and were added to the phantom organs. Imaging was performed using an SiPM PET/CT scanner with a 5-min acquisition. The data acquired in list mode were reconstructed using 3-dimensional ordered-subsets expectation maximization with varying iterations. Image evaluation was based on the depiction of the myocardial defect compared with normal myocardial accumulation. <b>Results:</b> Increasing the number of iterations improved the contrast of the myocardial defect for both tracers, with <sup>18</sup>F-flurpiridaz showing higher contrast than <sup>18</sup>F-FDG. However, even at 50 iterations, both tracers overestimated the defect accumulation. A bull's-eye image can display the flow metabolism mismatch using images from both tracers. <b>Conclusion:</b> SiPM PET enabled cardiac PET imaging in a 500-g ELBW phantom with a 1-g heart.
