Simultaneous multi-slice EPI has been combined with pulsed ASL to record several times more images than conventional EPI. Comparison of quantitative CBF maps and perfusion weighted images show good agreement to EPI. Comparisons to segmented 3D GRASE ASL shows differences in scan times and susceptibility artifacts with advantages of background suppression and higher SNR in 3D GRASE, while both achieve whole brain slice coverage.
