A method to measure Inflow Velocity Density of brain
tissue based on velocity selective ASL is proposed. The
method uses modified BIR-8 pulses to generate both
cosine and sine velocity dependent profiles in the
observed magnetization. Fourier analysis of the
resulting data yields the distribution of flow
velocities in the arterial blood supply to a given
voxel.
