A primary drawback of existing implementations of velocity selective arterial spin labeling (VSASL) is that the tagging pulse train produces velocity selective saturation rather than inversion, resulting in reduced SNR. We present here the design of composite velocity selective inversion pulse trains for use in VSASL. Preliminary results demonstrate B1 and B0 insensitivity, and higher SNR than current VSASL methods.
