Examples of inducible myocardial ischemia on stress CMR in asymptomatic patients. a Normal. 58-year old male with hypertension and history of non-ST elevation myocardial infarctino (NSTEMI) treated by percutaneous coronary intervention (PCI) of the left anterior descending coreonary artery (LAD). Stress CMR revealed no perfusion defect and late gadolinium enhancement (LGE) was negative, ruling out the diagnosis of myocardial ischemia. b inducible ischemia. 62-year old female with a history of inferior NSTEMI treated by PCI of the right coronary artery (RCA). First-pass myocardial stress perfusion images revealed a reversible perfusion defect of the anteroseptal wall (white arrows) without LGE, indicative of myocardial ischemia suggestive of significant LAD stenosis, confirmed by coronary angiography. c myocardial scar without ischemia. 73-year old male with prior anterior STEMI treated by PCI of the LAD. Stress CMR showed a subendocardial antero-septo-apical scar on LGE (orange arrows), with a colocalization of the perfusion defect (white arrows) and, therefore, no inducible ischemia. Coronary angiography confirmed the absence of significant stenosis. d myocardial scar with ischemia. 66-year old male with a history of inferior STEMI treated by PCI of the RCA. Stress CMR showed a subendocardial scar on the inferior wall on LGE sequences (orange arrows), and a perfusion defect of the antero-septo-basal wall (white arrows) on first-pass perfusion images, indicative of inducible myocardial ischemia. Coronary angiography revealed high-grade stenoses of the LAD
