Territorial ASL is a very interesting application for evaluation of patients with various cerebro-vascular disorders. Motion, however, is a serious issue, because its effects can not be easily corrected by post-processing. Reduction of scan time is an obvious strategy to reduce sensitivity to motion. Here we evaluate the use of shared rotating control for subtraction from multiple labeling conditions. Despite visible effects due to imperfect MT cancellation at early inversion times, this approach is useful for depiction of vascular territories.
