Figure 2 Patient examples. (Top row) Patient with a positive DE-CMR study demonstrating an infarct in the inferolateral wall (arrow) although perfusion-CMR is negative. The interpretation algorithm (step a) classified this patient as positive for CAD. Coronary angiography verified disease in a circumflex marginal artery. Cine-CMR demonstrated normal contractility. (Middle row) Patient with a negative DE-CMR study but with a prominent reversible defect in the anteroseptal wall on perfusion-CMR (arrow). The interpretation algorithm (step c) classified this patient as positive for CAD. Coronary angiography demonstrated a proximal 95% left anterior descending coronary artery (LAD) stenosis. (Bottom row) Patient with a matched stress-rest perfusion defect (arrows) but without evidence of prior MI on DE-CMR. The interpretation algorithm (step d) classified the perfusion defects as artifactual. Coronary angiography demonstrated normal coronary arteries. Abbreviations as in Figure 1.
