This study evaluated the labeling characteristics directly on various cerebral arteries using VSMRA with different VS labeling modules, including double refocused hyperbolic tangent (DRHT), eight-segment B1-insensitive rotation (BIR-8), delay alternating with nutation for tailored excitation (DANTE), Fourier transform based velocity-selective saturation (FT-VSS) and inversion (FT-VSI). Their effects on both the cerebral arterial vasculature and static brain tissue were visualized angiographically and compared quantitatively. And the implication for VSASL and VSMRA are discussed.
