Rapid Imaging of Multiple Vascular Territories using Cycled Arterial Spin Labeling with Independent Component Analysis

A method for regional ASL imaging is presented in which selected vascular territories were visualized at 1.5T in 2 minutes using a new labeling cycled scheme (cycled ASL) which varies the selective labeling of different inflow arteries before image acquisition with a single shot 3D GRASE read-out. When subject motion caused improper slab positioning of arterial labeling, the separation of vascular territories could be markedly improved using independent component analysis.
