Validation of the accuracy of ECV measurements using ANGIE T1 mapping. a This panel shows the correlation plot comparing left ventricular extracellular volume (LV-ECV) in pulmonary hypertension (PH) obtained with accelerated and navigator-gated Look-Locker imaging for cardiac T1 estimation (ANGIE) versus the modified Look-Locker inversion recovery (MOLLI) imaging. The ANGIE measurements of LV-ECV (in regions excluding scar on late gadolinium enhancement) in PH patients were in close agreement with those of MOLLI (r = 0.91; p < 0.001), confirming the accuracy of ECV measurements performed using ANGIE. b The corresponding Bland-Altman plot is shown.
