Answer

A full discussion of multidetector computed tomography (CT) technology is beyond the scope of this article, but is well addressed in other literature. [39, 40, 41] The 2 major recent advancements in multidetector CT technology are dual-source 64-slice CT and single-source 256- and 320-slice CT. Both of these techniques offer the possibility of reduced radiation dose compared with single-source 64-slice CT. Dual-source CT allows coronary CT angiography (CCTA) to be performed at higher heart rates. Currently, there is little published literature on 256- or 320-slice CCTA.
