4D flow MRI can derive 3D velocity of flow in a 3D volume in a shorter time in comparison to conventional methods. 4D flow can be used as an alternative and complimentary tool for assessment of valvular disease. In this abstract, we perform 3-way comparison of hemodynamic parameters derived from a new 4D UTE flow sequence with conventional 4D flow and Doppler Echocardiography in 6 patients with mild to moderate Aortic Stenosis. Results demonstrate good degree of correlation between the 3 methods.
