Figure 2 Bland-Altman diagrams of end-diastolic volume (EDV), end-systolic volume (ESV), and ejection fraction (EF), demonstrating mean difference (solid lines) and limits of agreement (dashed lines) between baseline echocardiography and magnetic resonance imaging (MRI) (left column), and contrast echocardiography and MRI (right column). (Bottom panels) closed circles = poor baseline image quality (n = 36); open circles = good baseline image quality (n = 51).
