Double pulse echoes--a novel approach for fat-water separation in magnetic resonance imaging.
A novel method to obtain separate fat and water images is presented. It is based on the replacement of the first echo generating pi pulse by two pi/2 pulses separated by a time delay corresponding to one-half cycle of the resonance frequency difference between fat and water protons.
