Optimized Spiral Pulse Sequences may have advantages for clinical myocardial perfusion imaging. The goal of this project was to evaluate how variations in the readout duration per interleaf, number of spiral interleaves, and spatial resolution affect the image quality and artifacts for first-pass myocardial perfusion imaging using spiral trajectories in human subjects.
