Figure 3From: Quantification of biventricular myocardial function using cardiac magnetic resonance feature tracking, endocardial border delineation and echocardiographic speckle tracking in patients with repaired tetralogy of fallot and healthy controlsBland Altman plot demonstrating interobserver agreement for global strain values of the left (LV) and right ventricle (RV) measured using feature tracking (FT) on CMR. Horizontal solid line represents the mean difference and the dashed lines mean +/− 2 standard deviations of the difference.Back to article page
