We evaluate the performance of the spiral PILS, SPIRiT and CS reconstruction techniques for the spiral first-pass myocardial perfusion imaging at acceleration factor 2 and 4 by downsampling the full acquired clinical data. We find that at lower acceleration factor, all the techniques work well while at the higher acceleration rate, images reconstructed by CS with finite-difference in time have similar SNR and image quality to the fully sampled images and may have a SNR advantage compared to other parallel imaging techniques.
