We propose a method to simultaneously acquire spin echo and gradient echo and form two images with distinct contrasts. The spin echo and gradient echo are created by phase-cycled RF pulses, so that they are shifted from each other in image space. In reconstruction, coil sensitivity information can be used to separate them. This study demonstrates the feasibility of extracting multiple echo components using controlled aliasing and parallel imaging reconstruction.
