Acute ischemic stroke requires extremely rapid imaging methods in order to effectively diagnose the occluded vessel(s) and provide timely intervention. Time-of-flight (TOF) angiography is central to this diagnosis. We investigate methods for optimizing TOF imaging given a 30 second acquisition window and demonstrate that highly accelerated methods provide significantly improved image quality relative to fully sampled data.
