In this work we present a new ASL approach for
non-enhanced MRA without the need of subtraction. Triple inversion recovery
TIR-ASL exploits the ability of the Nonselective Double Inversion-Recovery
sequence tobackground signal while
maintaining the signal in labeled blood using a regional inversion pulse.
