A new velocity selective ASL using an inversion pulse train was developed. Because inversion labeling was achieved with our new VSASL method, the labeling efficiency can be improved by approximately a factor of 2, compared to saturation labeling. The diffusion b value was the same in both label and control scans, therefore diffusion contamination was eliminated in the perfusion images.
