Triple velocity-encoded sensitivity (VENC) acquisition and reconstruction. Triple-VENC phase-contrast (PC) MRI sequence with a shared reference scan between low-VENC and high-VENC in the read, phase, and slice (i = x, y, z) directions, and combined use of low-VENC and high-VENC scans for reconstruction of the implicit VENC (iVENC) data. Imaging gradients are omitted for clarity. The red lines indicate the paired scans used to calculate low-VENC phase-difference images; the green lines indicate the high-VENC pairs; and the blue lines indicate the iVENC pairs. The first moments of each TR are described for all VENCs
