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.
