Free-breathing non-contrast flow-independent cardiovascular magnetic resonance angiography using cardiac gated, magnetization-prepared 3D Dixon method: assessment of thoracic vasculature in congenital heart disease

Table 3 Comparison of mean image quality scores between non-contrast-enhanced REACT-CMRA and contrast-enhanced steady-state- and first-pass-CMRA

	REACT–CMRA	Steady–state–CMRA	First–pass–CMRA	P value
Ascending aorta	4.1 ± 0.6^†	4.0 ± 0.7^†	3.3 ± 0.6^‡‖	< 0.001
Left pulmonary artery	3.8 ± 0.5	3.7 ± 0.8	3.6 ± 0.6	0.08
Left superior pulmonary vein	3.4 ± 0.6	3.7 ± 0.7^†	3.1 ± 0.6^‡	< 0.001
Coronary sinus	3.2 ± 0.6^†	3.3 ± 0.8^†	1.9 ± 0.8^‡‖	< 0.001
Right coronary ostium	3.1 ± 0.9^†‡	2.7 ± 1.0^†‖	1.4 ± 0.6^‡‖	< 0.001
Overall	3.5 ± 0.4^†	3.5 ± 0.6^†	2.7 ± 0.4^‡‖	< 0.001

Variables are given as mean ± standard deviation. P values were obtained using Friedmann test followed by Dunn multiple comparison test
