Here we present a method for field-of-view reduction in cardiac CINE-MRI. A nonlinear prephasing gradient generated by a high-performance monoplaner gradient system is used for signal spoiling along phase-encoding direction. A speed up of 60% without additional SAR is demonstrated in a clinically relevant application.
