Many strategies are employed to compensate for respiratory motion in PC MR exams, yet its effects on blood flow are often neglected. This study demonstrates the feasibility of a 4D radially-undersampled respiratory resolved acquisition and reconstruction for the characterization of respiratory induced blood flow changes in the great vessels.
