In this study, we investigated the characteristics of a 3D bSSFP sequence in ASL. We developed a BS-pCASL bSSFP with 2D (Ky and Kz) GRAPPA acceleration. The results were compared with conventional 2D EPI ASL. We demonstrated the advantages of a 3D BS pCASL-bSSFP sequence with high quality data while keeping the acquisition fast and efficient.
