Arterial Spin Labeling Angiography without the Need of Subtraction using a Triple Inversion Recovery Prepulse

Marcelo E. Andia¹, Rene M. Botnar¹

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 to background signal while maintaining the signal in labeled blood using a regional inversion pulse.
