简要总结
The goal of this study is to describe the techniques for coronary multi-slice CT angiography and to illustrate the spectrum of artifacts that can simulate coronary artery stenosis and lead to non-assessable segments using 128- and 160 multi-detector row CT scanners and discuss post-processing pitfalls with each. In addition, to review the normal anatomy and anatomic variants of the coronary arteries and discuss effective strategies for improving the diagnostic accuracy of coronary CT angiography.
