Distribution of CMR scans and segmentations judged of good or acceptable quality (score 1 or 2) according to the CMR image sequence

CMR image sequence	Proportion of studies with good/acceptable quality
LV contours
Short axis (SAX) stack	99.8% (n = 1976/1980)
Long axis 2-chamber	99.6% (n = 1974/1982)
Long axis 3-chamber	99.7% (n = 1979/1984)
Long axis 4-chamber	99.8% (n = 1981/1985)
RV contours
Short axis (SAX) stack	99.8% (n = 1977/1980)
Long axis 4-chamber	99.9% (n = 1983/1985)
LA contours
Long axis 4-chamber	99.6% (n = 1978/1985)
Long axis 2-chamber	97.0% (n = 1965/1982)
RA contours
Long axis 4-chamber	99.8% (n = 1981/1985)
Native T1 maps	98.9% (n = 1909/1930)
Aortic valve flow	99.7% (n = 1923/1928)

The proportion of studies deemed of good/acceptable quality was calculated per each image sequence after removing the studies with missing images or clips, which were due to that image sequence not being performed for those studies or corrupted files not being recognized by software.

LV, left ventricle; RV, right ventricle; LA, left atrium; RA, right atrium.
