Reperfusion injury components and manifestations determined by cardiovascular MR and MDCT imaging

Figure 2 Head-to-head comparison between first pass perfusion MR (top left) and first pass multi-detector computed tomography (MDCT) imaging (top right) in a 42-year-old man with acute reperfused infarct. Ischemic myocardium (arrows) appears as a hypoenhanced region with comparable extent on both imaging modalities. Bottom: Head-to-head comparison of DE-MR (bottom left) and DE-MDCT imaging (bottom right) shows a bright region comparable in size to enhanced inferior infarct (arrows). Note that the enhanced infarct on DE-imaging is substantially smaller than ischemic myocardium[38].
