Intra-and interobserver variability of CMR based measurements for stroke volume.
| Intraobserver Variability | Interobserver variability | |||
| Bias(95% Limits of agreement)* | CoV | Bias(95% Limits of agreement) | CoV | |
| PA Flow | -0.8 ± 1.7 (-4.1 to 2.4) |
3.1% | -0.9 ± 2.2 (-5.3 to 3.5) |
4.0% |
| Aorta Flow | -0.7 ± 2.6 (-5.4 to 5.0) |
2.7% | -1.3 ± 2.1 (-4.1 to 5.2) |
5.1% |
| RV volumes | -2.1 ± 5.2 (-12.3 to 8.1) |
8.7% | -2.6 ± 7.9 (-18 to 13.1) |
13.3% |
| LV volumes | -1.8 ± 3.2 (-8.0 to 4.4) |
5.4% | -2.6 ± 3.8 (-10.1 tot 4.9) |
6.4% |
*Bias and limits of agreement were determined according to the Bland and Altman method. CoV = coefficient of variability, PA = Pulmonary artery, RV = right ventricle, LV = Left ventricle.
