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.
