We describe a new approach for flow imaging and quantification consisting of a prototype cine arterial spin labeling (ASL) pulse sequence using a highly-accelerated radial fast interrupted steady-state (FISS) readout. The technique was successfully applied in several vascular regions (coronary arteries, pulmonary arteries, renal arteries, circle of Willis). These preliminary results suggest that cine FISS ASL has the potential to provide an efficient and visually-appealing alternative to phase contrast for the depiction and quantification of blood flow.
