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.
