Background: Cardiac CT is routinely performed to gain knowledge about cardiac or coronary anatomy, to detect or diagnose coronary artery disease, to evaluate patency of coronary artery bypass grafts or implanted coronary stents or to evaluate volumetry and cardiac function (including ejection fraction). Content: The presentation discusses the possibilities of cardiac CT in diagnosis of coronary artery disease, including the evaluation of coronary bypass graft patency and the diagnosis of in-stent restenosis. Available literature on coronary angiography CT will be reviewed and several cases will be used as examples to illustrate the imaging approach to coronary artery disease, cardiac and coronary anatomy. Interactive questions/answers with audience will be used to assess the proper delivery of the objectives. In particular the audience will be asked an opinion on multiple cases and the answers will be discussed during the lecture. Conclusions: Attendees will be familiar with indications, possibilities and limitations of CT coronary angiography.
