The effects of labeling location were assessed in
pseudo-continuous ASL by performing kinetic modeling of data acquired at
multiple post-labeling delays and by assessing the ratio of mean ASL intensity
to M0. Labeling location differences
resulted in significant MT effects on raw ASL data, and produced nonlinear
effects on bolus arrival time across vascular distributions.
