Recently, it was shown that phase-modulated balanced steady-state free precession (bSSFP) offers banding-free radial cine bSSFP images. Because this novel approach for bSSFP overcomes the need for short repetition times (TR), this work proposes to use more efficient spiral readouts with long TR of 15 ms. Banding free bSSFP cine images are demonstrated for either high temporal or high spatial resolution. The long TR furthermore facilitates fat suppression with spatial-spectral water-only excitation pulses which could improve depiction of the coronary arteries. Out of slice signal pileup at dark band frequencies is shown to be reduced with pre-saturation of those frequencies.
