Figure 5 A 38-year-old man presenting with atypical chest pain. The calcium screening examination revealed no calcifications within the coronary arterial tree (A). After administration of contrast agent, using a three-dimensional volume-rendering reconstruction technique, all epicardial vessels, including major side branches, could be depicted with sufficient image quality, allowing reliable exclusion of significant coronary artery lesions or the presence of extensive non-calcified atherosclerotic vessel wall changes (B, C, D). Ao = aorta; CV = cardiac vein; DBs = diagonal branches; LAD = left anterior descending coronary artery; LCX = left circumflex coronary artery; OM = obtuse marginal branch; PA = pulmonary artery; RCA = right coronary artery.
