In the current issue of the Netherlands Heart Journal, Zhang et al. describe the incidence of anomalous origins of the coronary arteries, demonstrated by dual-source computed tomography angiography (DSCT), in 1879 Chinese adults.
1 The three-dimensional images obtained by DSCT are particularly suited to demonstrate the origin and course of anomalous coronary arteries in relation to adjacent structures, as is clearly demonstrated by the illustrations in Zhang et al.’s paper. This usually allows an accurate and detailed diagnosis which, compared with conventional coronary arteriography, is easier to achieve. Essentially the same results may be obtained by magnetic resonance imaging, a method which, in contrast to DSCT, entails no radiation exposure but lacks the advantage of the short imaging time required for DSCT.
