CONTRAST-ENHANCED CARDIAC COMPUTED TOMOGRAPHY (CT) is being increasingly used for the investigation of patients with suspected coronary artery disease. Recent technological developments have allowed the reliable diagnosis of both coronary stenosis and occlusion with this modality. In addition to the identification of luminal stenosis, CT has the potential to visualize coronary plaque, collateral circulation, myocardium, and left ventricular function. Although the typical CT appearance of chronic coronary occlusion (extensive calcification and negative remodeling within the artery, potential presence of collateral coronary circulation and, in most cases, impaired left ventricular function associated with thinned myocardium) is well known, characteristics of acute occlusion have not been well described. The distinction between acute and chronic coronary occlusion has particular importance for the management of patients presenting with acute chest pain. In this series of cases, we highlight some characteristic features of acute and chronic coronary occlusions as demonstrated by contrast enhanced cardiac CT (Figs. 1 to 5).⇓⇓⇓
