Detection of myocardial viability by LGE-CMR. The figure shows five different patients with an increasing amount of late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR). LGE-CMR can determine the degree of non-viable myocardium as a continuous spectrum of increasing transmural extent of scar tissue. Dysfunctional myocardium without scar is viable. Viability proportionally decreases with increasing transmurality of scar. A small apical thrombus is also evident for the patient on the bottom row. See also Supplementary data online, Movie S3
