Objective: In this study, we evaluated the utility of slice MDCT multidetector computed tomography to assess stent patency after coronary artery stenting. Qualitative assessment of 61 coronary stent lumens by MDCT is reported, and the reasons preventing assessment were investigated. Results: All non-assessable stents were non-assessable due to partial volume effects and metal artifacts.

To evaluate instent restenosis, conventional coronary angiography was performed on the 54 assessable stents in 48 patients, and the results were compared with the MDCT results. Based on the results of the conventional coronary angiography, MDCT correctly detected four in-stent restenosis. Conclusion: Despite some limitations, slice MDCT provides sufficient evaluations of some coronary stents, and can detect in-stent restenosis with high accuracy.
