Comparison of mean image quality scores between native relaxation-enhanced angiography without contrast (REACT) and contrast-enhanced magnetic resonance angiography (CMRA)

	Native REACT CMRA	Contrast-enhanced steady-state CMRA	P value
Ascending aorta	4.8 ± 0.5	4.3 ± 0.8	< 0.001
Main pulmonary artery	4.2 ± 1.0	4.6 ± 0.6	0.031
Left pulmonary artery	3.7 ± 0.8	4.0 ± 0.7	0.138
Right pulmonary artery	3.7 ± 0.9	3.9 ± 0.8	0.185
Left superior pulmonary vein	3.3 ± 0.9	3.7 ± 0.5	0.005
Right superior pulmonary vein	2.9 ± 1.0	3.5 ± 0.8	0.003
Superior vena cava	3.8 ± 0.8	4.0 ± 0.8	0.095
Inferior vena cava	4.6 ± 0.5	3.2 ± 0.8	< 0.001
Right coronary artery origin	4.0 ± 0.9	3.2 ± 1.0	< 0.001
Left coronary artery origin	4.1 ± 1.0	3.3 ± 1.1	0.001
Overall	3.9 ± 1.0	3.8 ± 0.9	0.018

The image quality was scored on a five-point scale (5 = excellent, 4 = good, 3 = intermediate, 2 = poor, 1 = non-diagnostic). Variables are given as mean ± standard deviation. P values refer to the Wilcoxon signed-rank test. Bold p-values indicate statistically significant results
