Coronary Angiography by 64-Row CT

To the Editor: In their article on the Coronary Artery Evaluation Using 64-Row Multidetector Computed Tomography Angiography (CORE 64) trial (Nov. 27 issue), 1 Miller et al. rather miss the point of contemporary computed tomographic (CT) angiography, as do Redberg and Walsh in their accompanying Perspective article. 2 CT angiography will never replace catheter angiography in the same manner that CT pulmonary angiography has usurped its invasive counterpart as the standard. Even the use of CT scanners with a steadily rising number of detectors is unlikely to fully overcome the limits on spatial resolution imposed by cardiac motion. With this in mind, . . .
