Technical development across all cardiac imaging modalities continues to evolve rapidly, often outpacing the ability to perform rigorous clinical validation and application. Current and anticipated technical developments of CT scanners and software are intended to improve the spatial and temporal resolution of cardiac CT images while reducing the radiation dose received from a typical examination. They include wider detector arrays that allow higher numbers of simultaneously acquired image slices, faster x-ray tube rotation times, and the use of alternative image reconstruction techniques that target image noise, all of which could improve the diagnostic value of CCTA in currently challenging scenarios, such as calcified coronary arteries and coronary stents.
