Cardiac output and myocardial displacement pre and post contrast agent acquisition. A) Agreement shown with line of identity (left) of cardiac output between pre and post contrast agent acquisitions. Bland-Altman plot (right) showing differences between pre and post contrast agent acquisitions (mean and 2SD indicated; mean 0.03 l/min, limits of agreement -0.30-0.35 l/min). Measurements by observer 1 are plotted. B) Bland-Altman plots showing differences between myocardial displacement for maximum (left; mean 0.13 mm, limits of agreement -1.79-2.05 mm) and average (right; mean 0.07 mm, limits of agreement -1.41-1.56 mm) values pre and post contrast agent administration (mean and 2SD indicated). CA = contrast agent; MD = myocardial displacement.
