Choosing a proper velocity encoding (Venc) setting is challenging when covering large vascular territories with a single 4D PC MRI acquisition. Dual Venc acquisitions can improve the VNR while maintaining dynamic range utilizing (1) a low Venc data set to provide a good VNR and (2) a high Venc data set to identify and correct for velocity aliasing. In this in-vivo study, we compare flow measurements from an accelerated dual Venc PC VIPR acquisition with those obtained with a standard PC VIPR and targeted standard Cartesian 2D phase contrast (2D PC) acquisitions.
