The properties of the cerebral vasculature are of clinical relevance and thus of interest for investigation. Here an ASL-based 3D angiographic technique (CINEMA-STAR) is used to measure blood arrival times and blood velocities of a bolus labeled in the neck. Results are shown to be in broad agreement with existing methods.
