Criteria for imaging quality parameters of cardiac MRI cases

Score	Overall image quality	Systemic arteries	Pulmonary arteries	Pulmonary veins	Valves	Ventricles
5	Outstanding; small arteries with high SNR and well-delineated	Both coronary origins well seen	Arteries seen to within 1 cm of pleura	Can sharply see entrance to LA for all veins	Sharp on all phases	Sharp trabeculae
4	Excellent; medium arteries with high SNR and well-delineated	One coronary origin well seen	All segmental arteries well seen	Can sharply see entrance to LA for some veins	Sharp	Trabeculae seen
3	Good; all medium arteries can be assessed	Arch vessels well seen	Most segmental arteries well seen	Can see entrance to LA of all veins	Blurred	Sharp border
2	Diagnostic; all but 1–2 medium arteries assessed	Aorta well seen	Lobar arteries well seen	Can see entrance to LA of some veins	Partially seen	Can segment
1	Limited assessment of several medium arteries	Aorta not well seen	Right and left pulmonary arteries well seen	Cannot see entrance to LA	Not seen	Cannot segment

LA left atrium, SNR signal-to-noise ratio
