As opposed to Velocity Selective Arterial Spin Labeling (ASL), which labels both arterial and venous blood, a new ASL technique is demonstrated, called AccASL, which labels flowing spins based on acceleration. It has been shown that the proposed AccASL is a promising method to enable measurement of the perfusion with spatially non-selective labeling, elimination of venous label and high signal intensity in grey matter.
