Table 1.

Quality assessment of cine short-axis (SAX) images. The image quality score corresponds to the sum of qualitative scoring based on 6 criteria (range of score: 0–5). One point was given if an artefact impeded the visualization of > 1/3 of the ventricular endocardial border at end-systole and/or end-diastole on a single SAX slice. If such artefact involved 2 slices or ≥ 3 slices, 2 and 3 points were given, respectively. Incorrect short-axis orientation was graded with 2 points

	0	1	2	3	Maximum Score
1. Wrap around	No	1 slice	2 slices	≥3 slices	3
2. Respiratory ghost	No	1 slice	2 slices	≥3 slices
3. Cardiac ghost	No	1 slice	2 slices	≥3 slices
4. Image blurring / mis-triggering	No	1 slice	2 slices	≥3 slices
5. Metallic artefacts	No	1 slice	2 slices	≥3 slices
6. Orientation of stack	Correct	–	Incorrect	–	2
