4D Dual-Venc Spiral Flow


Dual-Venc flow acquisition sequences perform flow imaging with differing Vencs. The technique can be used to improve velocity to noise ratio and image quality for diastolic flow velocities as part of a single scan. In this paper, Dual-Venc was used in conjunction with spiral read-out trajectories, offering a faster coverage of k-space. The results illustrate that 4D Dual Venc Spiral Flow behaves similarly to 4D Dual-Venc Cartesian Flow but with the benefit of faster acquisition time and lower echo time (TE).
