Figure 2
Myocardium at risk by T2-weighted imaging and by endocardial extent of infarction. A) MaR by endocardial extent of infarction versus T2-weighted imaging. Solid line = line of identity; dashed line = regression line; r2 = 0.17, p = 0.002. The two patients with an aborted infarction and the two patients with more than 90% myocardial salvage are encircled. B) Bland-Altman graph showing the difference between myocardium at risk quantified by endocardial extent of infarction versus T2-weighted imaging. The difference between endocardial extent of infarction and T2-weighted imaging was -11 ± 12%. Solid line = mean of endocardial extent of infarction - T2-weighted imaging; dashed lines = ± 2 SD. The two patients with an aborted infarction and the two patients with more than 90% myocardial salvage are encircled.
