The purpose of this work was to perform a preliminary evaluation of a self-retraced spiral in-out trajectory for 3D turbo/fast spin-echo imaging. By sampling k-space locations twice with a single spiral in-out trajectory, off-resonance effects are robustly attenuated and image quality is improved compared to using a standard spiral in-out trajectory.
