Multi-delay arterial spin labeling (ASL) is a powerful MRI technique that allows to non-invasively measure both cerebral blood flow and arterial transit time quantitatively, which has great potential for clinical applications. However, usage of multi-delay ASL is limited by the prolonged scan time with the number of post-labeling delay times used for acquisition. Up to date, low-rank property has been observed in signals of various MR applications where low-rank approach has demonstrated promising results. This work shows that the dynamics of ASL signal display low-rank property and the scan time of multi-delay ASL can be accelerated using low-rank image reconstruction.
