Here, a Y-shaped pulsatile flow phantom is used to evaluate the flow quantification error, as measured by 2D CINE PC, caused by magnetic susceptibility in the presence of clinically used MR-conditional ferromagnetic stents, even in ROIs where the artifact is not visualized in magnitude image. Our results indicate that flow measurements should be performed more than 12 mm away from the proximal or distal part of the stent to achieve accurate flow measurements.
