Arterial spin labeling (ASL) is a non-invasive MRI perfusion technique that can quantify tissue blood flow, which is meaningful for clinical applications. However, ASL perfusion images always have a limited signal-to-noise ratio (SNR). We aimed to using the echo planar imaging with compressed SENSE (EPICS) to obtain high-quality brain ASL images. Eleven healthy subjects and four patients with intracranial infarction were enrolled, and underwent ASL imaging with and without EPICS. The results demonstrated the feasibility of EPICS to increase the quality of ASL images.
