Myocardium at risk by T2-weighted imaging and endocardial extent of infarction versus infarct size by late gadolinium enhanced CMR. A) Myocardium at risk by T2-weighted imaging in relation to infarct size by late gadolinium enhanced CMR presented with the line of identity. The myocardium at risk by T2-weighted imaging was consistently greater than the infarct size in all patients. B) Myocardium at risk by endocardial extent of infarction in relation to infarct size by late gadolinium enhanced CMR presented with the line of identity. The myocardium at risk by endocardial extent of infarction was, in general, greater than the infarct size. For one patient the infarct size was, however, greater than the myocardium at risk. The two patients with an aborted infarction and the two patients with more than 90% myocardial salvage are encircled.
