Representative Images from STEMI Patients with LAD, LCx and RCA Myocardial Infarctions. X-ray Digital subtraction angiography (X-ray DSA) images acquired before and after PCI, along with corresponding short-axis myocardial T2-STIR and CE-SSFP showing at-risk regions and infarct territories (LGE) acquired at 3T are shown. On X-ray DSA images, the red arrows refer to occlusive or substantially narrowed vessels, and the red box with dotted line demonstrates the re-establishment of blood flow following recanalization of the corresponding vessel. On CMR images, epicardial and endocardial borders are delineated by green and red borders, respectively. The left columns shows the raw images and the right columns shows the same images processed using semi-automatic threshold-based signal detection. The edematous myocardium delineated by the T2-STIR and CE-SSFP images are shown as a region enclosed by the pale blue areas and irreversibly damaged myocardium is identified on LGE images as yellow areas
