  1. Results of mean values and biases of cardiac magnet resonance imaging (CMR), manually corrected semi-automatic and uncorrected semi-automatic three-dimensional echocardiography (3DE) analysis. Means expressed with ± standard deviation (SD). 3DE image quality: 2 means fairly visualized, 3 good and 4 excellent visualized. n = 53 for 2+3+4 and n = 27 for 3+4.
  2. †: compared to CMR, p ≤ 0.001; ‡: compared to corrected 3DE, p ≤ 0.001; No significant differences in means and biases between image quality more than 2 compared to less than 3.
