While radiation exposure may become less of a concern with the development of low-dose scan protocols, there is still the need for intravenous injection of potentially harmful contrast media. Coronary CT angiography has the potential to identify patients with severe but noncalcified coronary artery disease, which would be missed by unenhanced CT. Finding severely obstructive disease is rare, and the overall prognosis of asymptomatic patients without detectable coronary calcium is excellent (<1% annual event rate).
