Fig. 8From: Using a respiratory navigator significantly reduces variability when quantifying left ventricular torsion with cardiovascular magnetic resonanceVariability of torsion due to enforced inconsistent end-expiratory positions versus the subject-specific range of end-expiratory position. There was a moderate positive correlation between RMSE of LV torsion due to inconsistent expiratory positions and the range of end-expiratory position (r = 0.50, p = 0.049). The dashed gray line illustrates the linear best fitBack to article page
