Vessel Encoded Arterial Spin Labeling Using Fourier Encoding

Youngkyoo Jung¹, ²

PCASL-based VE-ASL methods often require long scan times and complicated clustering algorithms to classify multiple vascular territories. VE-ASL can be performed by encoding blood signal in the Fourier space based on the source location. We have demonstrated that the proposed Fourier encoding method allows quantitative vascular territory mapping without knowledge of accurate locations of feeding arteries or complicated post-processing algorithm. In addition, the method is immune to phase errors due to resonance offsets and can be performed within clinically relevant scan time (<4min).
