Images in 80-year-old man with chest pain. A, Myocardial CT perfusion image at stress demonstrates subendocardial perfusion defect in anteroapical and apical walls (arrows). B, Myocardial CT perfusion image at rest shows that defect is reversible. C, SPECT images demonstrate normal myocardial perfusion with subdiaphragmatic attenuation artifact. D, Image from invasive coronary angiography demonstrates 85% stenosis in proximal left anterior descending artery (arrow).
