In this study we offer a unique approach to achieve simultaneous evaluation of tissue and blood flow velocities from a single low-VENC phase-contrast dataset (i.e. prescribed for measurement of tissue velocities). A novel phase unwrapping algorithm (PUROR) is tested for this purpose. The in vivo results demonstrate that the presented technique allows for simultaneous quantification of cardiac tissue and blood flow velocities within a single image acquisition.
