This study was to evaluate the diagnostic value of myocardial perfusion in patients with acute myocardial infarction (AMI) and “infarct-like myocarditis” using IVIM-DWI imaging. And the results showed: 1. Insufficient oxygen in the necrotic or infarted myocardium might affect myocardial perfusion and function. 2. IVIM-DWI may be a reliable sequence to evaluate different myocardial perfusion patterns in acute myocardial infarction and infarct-like myocarditis. 3. Acute myocardial infarction may exhibit lower myocardial perfusion status compared with infarct-like myocarditis due to different pathophysiological process.
