Regional myocardial ¹⁸F-FDG uptake is highly specific and sensitive for exercise-induced myocardial ischemia and may persist for 24 h after an episode. Exercise and rest ^99mTc-sestamibi perfusion and ¹⁸F-FDG imaging were performed on this patient with exertional angina. Exercise-induced perfusion abnormality was reversible on rest images, and intense ¹⁸F-FDG uptake on exercise images was not seen on rest images. The patient had 85% right coronary artery stenosis.
