We introduced a new single echo MRAV method with inversed vessel-tissue contrast, which shows arteries with dark blood contrast via low VENC flow dephasing and veins with bright blood contrast using quantitative susceptibility mapping. This method has the potential to reliably extract both arterial and venous networks separately from the data from single echo GRE data, without the penalty of total scan time or image misregistration. The reconstructed arterial and venous maps are shown, and the potential application and future works of this method are discussed.
