摘要冠状动脉CT血管造影（CCTA）作为一项无创性影像检查技术，在冠脉支架术后随访中发挥着越来越重要的作用。虽然冠脉支架CT成像仍受限于线束硬化伪影与部分容积效应等，但随着CT设备的不断更新以及重建算法的逐步改进，CCTA的冠脉支架显示能力已得到了大幅提高。同时，CCTA结合功能学技术可以提供不同的功能学指标，在解剖层面基础上又新增了功能层面上的评估，从而给临床提供了形态和代谢的综合信息。本文就CCTA在冠脉支架评价方面的影像学科研进展进行综述。

Abstract：As a noninvasive imaging technique, coronary CT angiography(CCTA) plays an important increasingly role in the follow-up of coronary stenting. Although CT imaging of coronary stent is still limited by beam hardening artifact, partial volume effect etc, CCTA of coronary stenting has been significantly improved with the continuous updating of CT devices and the gradual improvement of reconstruction algorithms. At the same time, CCTA combined with functional techniques provides different functional indicators, adding the functional level based on the anatomical level of assessment, so as to provides comprehensive informationa of morphology and metabolism for clinical. In this paper, imaging research progress of coronary artery stent evaluationin CCTA were reviewed.
