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.
