Figure 3 Bland–Altman plots showing the mean difference (solid lines) and the limits of agreement (dashed lines) between echocardiographic and MRI measurements of LV end diastolic volume (A and B), end systolic volume (C and D) and EF (E and F). Left = baseline echocardiography; right = postcontrast echocardiography. The value for each patient is represented by a diamond. For each variable the limits of agreement become more narrow after contrast agent administration.
