A validation study of a pathline based left ventricular (LV) blood flow quantification approach is presented. The approach integrates morphological and three-directional, three-dimensional cine phase-contrast MRI flow data, to separate the blood that transits the LV into four components. The validation includes comparison of the LV outflow obtained from this approach to results from clinically applied methods of determining LV outflow: 2D through-plane cine PC-MRI and Doppler ultrasound. Additionally inflow and outflow volumes obtained from the pathline based approach were compared.
