Role of 128-slice, dual-source CT coronary angiography as a novel imaging technique in assessment of in-stent restenosis

Abstract

ABSTRACT Background: Over the past 35 years, catheter-based intervention has become the dominant form of coronary revascularization. Percutaneous coronary interventions are increasingly performed. The most important advance in the field of percutaneous coronary interventions was the introduction of coronary stent implantation in the 1990s, which led to reductions in incidence of restenosis. The use of multi–slice CT is gaining increasing acceptance for noninvasive cardiac imaging. Recent years with the new emerging machines have demonstrated successful application of multi–slice CT angiography for the noninvasive assessment of coronary artery disease and the evaluation of coronary artery stents. Aim of the Work: To evaluate the role of 128-slice, dual-source CT coronary angiography as a novel technique in assessment of coronary artery in-stent restenosis.
