The change in the signal intensity of perfusion-weighted images induced by arterial spin labeling is very small, which is even lower in the arterial spin labeling (ASL) TrueFISP Perfusion Imaging due to the low flip angle. The number of repetitions necessary to achieve reasonable SNR makes breath-hold scans difficult for patients in clinical application. In the current work, we investigated the potentials and drawbacks of using a respiratory triggered, ASL FISP imaging sequence at such 1.5 Tesla for quantitative mapping of Pancreas/Liver perfusion.
