Merging data across the two contrasts (T1-weighted and T2-weighted) and the two acquisition planes (short-axis and four-chamber) ( n = 41 paired image sets), preference for radial bSSFP over standard-of-care Cartesian fast spin-echo was highly significant for overall image quality (3.9 ± 0.59 vs. 3.4 ± 0.74, P < 0.001), fat suppression (4.2 ± 0.4 vs. 3.5 ± 0.53, P < 0.001), RV free wall visibility (3.8 ± 0.75 vs.2.8 ± 0.88, P < 0.001), LV free wall visibility (4.3 ± 0.67 vs. 3.6 ± 0.88, P < 0.001) and septum visibility (4.5 ± 0.6 vs. 4.0 ± 0.74, P < 0.001).
