Figure 1 A Significant Lesion in the LAD

Volume-rendered dual source computed tomography scanner image (colored image) and corresponding conventional angiography image of the right coronary artery (RCA), left anterior descending artery (LAD), circumflex artery (CX), intermediate branch (IM), diagonal branches (D1, D2) in a 57-year-old man with stable angina and an equivocal bicycle test. Mean heart rate during scanning was 78 beats/min. A significant lesion was found in the midpart of the LAD (arrow) with detailed color inlay, curved multiplanar reconstruction (bottom left), and maximum intensity projections image (bottom right). The proximal part of the CX showed an occlusion (arrowhead).
