A dual-echo (blade) Spin-Echo propeller is presented for motion and flow robust T1-w imaging. With the echoes are played out orthogonally to each other, a parallel imaging acceleration of R=2 is used relying on mutual cross-calibration. Shortening the blade acquisition time is important to avoid intra-blade head motion.
