Images in a 71-year-old man with CAD, status post three-vessel coronary artery bypass graft procedure and recurrent angina. (a) Pharmacologic stress, time-resolved myocardial CT perfusion maps superimposed on anatomic coronary CT angiography study demonstrates an occluded left internal mammary artery graft to the left anterior descending coronary artery (black arrow), with an associated stress-induced perfusion deficit in the anterior left ventricular myocardium (white open arrow). (b) Attenuation values within healthy (solid line) and diseased (dashed line) myocardium across the duration of the CT perfusion examination show persistently lower enhancement in the ischemic myocardium. (c) The perfusion deficit shown with CT correlates well with pharmacologic stress SPECT study in the same location (arrows).
