In this work, we implemented background suppression for continuous arterial spin labeling based MR angiography to suppress the noise resulting from the influence of magnetic transfer effect. Pulsed labeling is also incorporated in the background suppression scheme to address the flow void effect in continuous labeling. With the proposed method, the overall vessel clarity was improved without prolonging the scan time.
