Highly accelerated real-time tagging at 3 T. Steady-state free-precession imaging has a higher signal-to-noise ratio than gradient-echo and is thus more robust to high acceleration rates. Tag lines were perpendicular to phase-encoding to preserve harmonics. Off-resonance artifacts were reduced by using fat-saturation (S1) and steady-state ramp-up (S3) pulses. Only five pulses were used to minimize the delay between tag preparation (S2) and the first imaging frame
