Figure 3 Irreversible and Reversible Myocardial Injury in Acute Reperfused Infarcts in 2 Patients as Visually and Semiautomatically Defined
(A) Patient 1. Cardiovascular magnetic resonance (CMR) images 3 days after an acutely reperfused infarct with a subtotal (99%) occlusion of the left anterior descending artery in a 71-year-old patient. (B) Patient 2. CMR images 1 day after reperfusion of an occluded right coronary artery in a 57-year-old patient. Red indicates the result of a semiautomatic delineation of pixels with abnormal signal as defined by a signal intensity of >2 SD above mean signal intensity of the remote myocardium. Note that the spatial extent of myocardial injury in the edema-sensitive T2 imaging is consistently larger than that of the necrosis-sensitive late enhancement.
