Invasive diagnostic imaging technique of coronary atherosclerosis has rapidly developed. For example, intravascular ultrasound(IVUS) is recognized as an essential device for percutaneous coronary intervention to evaluate the vessel wall, vascular lumen and coronary plaque morphologies because of its accuracy for quantitative analysis capability. Recently new imaging modalities such as radio-frequency signal analysis, elastography and contrast harmonic echography have been developed for the evaluation of histological characteristics. Also, optical coherence tomography(OCT), which provides approximately ten-times higher-resolutional cross-section images of the coronary arterial wall in comparison with IVUS, became available in clinical setting. In this article, we review the latest progress of the invasive diagnostic imaging of coronary atherosclerosis.
冠状动脉粥样硬化的侵入性诊断成像技术发展迅速。例如，血管内超声（IVUS）因其定量分析能力的准确性，被认为是经皮冠状动脉介入治疗中评估血管壁、血管腔和冠状动脉斑块形态的重要设备。最近，诸如射频信号分析、弹性成像和对比谐波超声等新的成像方式已被开发用于评估组织学特征。此外，光学相干断层扫描（OCT）与IVUS相比，能提供分辨率约高十倍的冠状动脉壁横截面图像，现已应用于临床。在本文中，我们回顾了冠状动脉粥样硬化侵入性诊断成像的最新进展。
