Abstract

Dynamic stress myocardial CT perfusion (CTP), a functional imaging modality that is proven highly valuable for evaluating myocardial ischemia, is one of the most challenging CT examinations being carried out in practice. The implementation varies among current CT systems on the image acquisition mode, the dose management, as well as the strategy to combine myocardial CTP with coronary CT angiography (CCTA), which may result in a large difference in the efficiency of the clinical workflow. Following the so-called “one-stop-shop” concept, a new genuine protocol has been implemented by using a 320-row CT imaging system, with rapid volumetric image acquisition in axial mode, adaptive temporal sampling rate, CCTA extracted from the boosted arterial phases within the CTP, and the deep learning algorithms ensuring the reconstructed image quality. This paper describes the imaging protocol and the associated technical parameters in detail and compares this protocol to those reported previously in the literature.
