The development of atherosclerotic plaques occurs slowly over decades. This provides an opportunity for diagnostic imaging to identify patients before clinical events occur. Computed tomography (CT) is an important imaging technique that is rountinely used for the noninvasive imaging of the arteries throughout the body. One of the most recent innovations in CT is the use of two tubes with different energy, which is called dual-energy CT. This technique has the potential to improve the abilities to differentiate various body tissues with CT, and to increase the inherently low contrast of single-energy CT. This chapter reviews the current status and potential future role of dual-energy CT to detect, characterize and differentiate atherosclerotic plaques.
