The mechanism of bSSFP edema contrast in acute myocardial infarction imaging is not well understood. To assess the various mechanisms that enable the detection of myocardial edema on the basis on bSSFP imaging, controlled experiments were conducted in canine models subjected to ischemia reperfusion injury. Results show that relaxation and M0 changes have significant contribution to the detection of edematous myocardial zones following acute injury to the myocardium on the basis bSSFP imaging.
