A summary of averaged reader scores for each of four categories per pulse sequence per field strength. The two groups (standard and real-time with radial CS) were significantly different for temporal fidelity, artifact, and noise scores (P = 0.013), except for myocardial wall definition (P > 0.05). Interestingly, real-time cine with radial CS produced higher artifact and noise scores than standard cine. Each category is scored from 1 to 5 (worst to best). Note that for all four categories, mean scores were greater than 3.0, suggesting that all scores were deemed clinically usable by our readers.

Field Strength	Sequence	Myocardial Edge Definition	Temporal Fidelity	Artifact	Noise
1.5T (N=16)	Standard Cine	4.4 ± 0.5	4.9 ± 0.3*	4.2 ± 1.0*	4.4 ± 0.3*
	Radial CS	4.6 ± 0.4	4.4 ± 0.6*	4.8 ± 0.3*	4.8 ± 0.3*
3T (N=18)	Standard Cine	4.6 ± 0.6	5.0 ± 0.1*	4.3 ± 0.7*	5.0 ± 0.0
	Radial CS	4.5 ± 0.5	4.3 ± 0.6*	4.7 ± 0.3*	4.9 ± 0.2
