Comparison of images acquired at various number of readouts per segment. A balanced steady state free precession (bSSFP) off-resonance band near the imaging slice, which is not observed on the ECG-gated breath-hold reference cines (ECG BH, Row 1) due to its sequential PE, caused severe dark flow artifact (white arrows) with the original GS (Row 2) due to the compounding effects of large PE jumps and flow. The artifact is significantly reduced when readouts are sorted into segments of ascending or descending PEs (sGS FB, Row 3–5). At more than 4 readouts per segment, the artifact becomes essentially unnoticeable. bSSFP: balanced steady state free precession. PE: phase encode. RO: readout. SAX: short axis. LAX: long axis
