Coronary computed tomography (CT) is one of the most rigorously tested imaging modalities. The history of evidence of coronary CT reflects the hierarchical model of efficacy of diagnostic imaging proposed by Fryback and Thornbury. Coronary CT has gone through technological evolution from electron beam CT to helical CT to multidetector CT. As technology improved, it also had to meet higher bars for evidence from proof of concept to diagnostic accuracy to evidence that it improves outcomes compared with its competitors.
冠状动脉计算机断层扫描（CT）是经过最严格测试的成像方式之一。冠状动脉CT的证据史反映了弗莱巴克（Fryback）和索恩伯里（Thornbury）提出的诊断成像功效分层模型。冠状动脉CT经历了从电子束CT到螺旋CT再到多探测器CT的技术演变。随着技术的进步，它还必须满足更高的证据标准，从概念验证到诊断准确性，再到与竞争对手相比能改善预后的证据。
