Influence of cardiac motion on stent lumen visualization in third generation dual-source CT employing a pulsatile heart model

摘要

Objective: To detect an in-stent restenosis, an invasive coronary angiography is commonly performed. Owing to the risk associated with this procedure, a non-invasivemethod to detect or exclude an in-stent restenosis is desirable. The purpose of this study was to evaluate the influence of cardiac motion on stent lumen visibility in a third-generation dualsource CT scanner (SOMATOM Force; Siemens Healthcare, Forchheim, Germany), employing a pulsatile heart model (CoroSim r; Mecora, Aachen, Germany).
