Coronary spiral CT

This dissertation describes the use and clinical potential of ECG gated multislice spiral computed tomography in patients with coronary artery disease. First the use of other non invasive cardiac imaging, i.e. the previously mentioned electron beam CT and magnetic resonance imaging is reviewed (chapter 2.1). Part 3 contains studies related to the characteristics of multislice spiral CT for the imaging of the heart and coronary arteries, and the diagnostic potential of ECG gated spiral CT coronary angiography to detect and visualize obstructive coronary artery disease in symptomatic patients, using conventional coronary angiography as the standard of reference. Part 4 is focussed on the feasibility and characteristics of coronary wall imaging by CT, including the assessment of non calcified atherosclerotic plaque material. The usefulness of contrast enhanced multislice spiral CT in symptomatic patients who previously underwent coronary artery bypass grafting and percutaneous coronary intervention with stent implantation is discussed in part 5. Finally, the first results with the latest generation 16 slice computed tomography scanners and patient preparation with ~ receptor blockers are described in part 6, including a review and future outlook on the continuing development and clinical use of non invasive coronary angiography with spiral computed tomography.
