In this work, we present how the challenges of acquiring dynamic angiography images at ultra-high fields can be overcome using an adapted STAR sequence. The cerebral vasculatures of three volunteers were imaged in a 7 Tesla MR system with an in-plane resolution of 0.56x0.56 mm so that small peripheral vessels could be visualized. The results show that with the adapted sequence, high-resolution dynamic ASL imaging at 7 Tesla is feasible within an acquisition time of 6:45 min.
