The Nonculprit Coronary Lesion as Seen by Coronary CT Angiography: What Should We Be Looking For?

摘要

Coronary plaque burden and plaque vulnerability are important for predicting future cardiac events and there is great interest in developingnoninvasive tools to detect and quantify them. The article on the quantification of nonculprit coronary lesions using cardiac 64-MDCT angiography [1], published in this issue of the American Journal of Roentgenology,raises some interesting related questions. Is it worthwhile to quantify the nonculprit lesion severity or should coronary lesion detection and characterization be more important? And if lesion quantification is attempted, do we have reliable tools to do so?
