Identification of area at risk (AAR) using cardiovascular magnetic resonance (CMR) T1 mapping. AAR was automatically delineated (pink contour) using threshold of 2SD above the mean value of remote reference region of interest (ROI, contoured in blue) placed 180 degrees opposite to the injured myocardium. This process was performed irrespective of presence of microvascular obstruction (MVO)
