The tracer kinetic properties of velocity selective inversion pulses were characterized using a two compartment model. The properties of these pulses indicate that VSI pulses can produce large input functions and little or no transit time effects. These translate into speed and SNR gains for perfusion images of both grey and white matter without the use of contrast agents.
