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 |
