Balanced steady-state free precession (b-SSFP) imaging of left atrial cine is severely affected by off-resonance artefacts, particularly in the pulmonary veins. Acquisition and combination of data sets with different phase-cyclings has been shown to remove banding artefacts with a trade-off in scan time. The purpose of this work is to present an approach to banding artefact removal in b-SSFP imaging for left atrial cine. We propose the use of interleaved, undersampled radial projections with LC-SSFP. This method provides increased pulmonary vein conspicuity and image quality with only minor increase in scan time and streaking artefact.
