This study aimed to identify the optimal site for AR assessment using 2D and 4D MR flow measurements. We retrospectively analyzed patients with congenital aortic valve disease, performing 2D and 4D MR flow measurements in the ascending aorta while using midpulmonary artery measurements as a reference. The best agreement in % AR between 2D and 4D flows was at the aortic valve. Vortices in the ascending aorta led to AR overestimation in 2D measurements. For congenital aortic valve disease, the most accurate AR quantification occurs at the aortic valve using 2D and 4D MR flow.
