Summary

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.

Conditions

• Computed Tomography Angiography
• Coronary Artery Disease

Interventions

Type	Name	Description
RADIATION	Coronary computed tomography angiography	All patients will be subjected to: Two CT scans (coronary calcium scoring and angiography) using 128 or 160-row scanners with a slice thickness of 0.5 mm (Revolution Evo 128, GE Health care, Chicago, Illinois, USA) or (Aquilion 160, Canon Medical Systems, Tochigi, Japan). Calcium scoring will be performed with the use of prospective electrocardiographic gating with 400-ms gantry rotation, 120-kV tube voltage, and 300-mA tube current. For CTA, retrospective electrocardiographic gating will be used, with heart rate adjusted gantry rotations of 350 ms to 500 ms to enable adaptive multisegmented reconstruction. Iopromide (Ultravist 370, Bayer AG, Berlin, Germany) is the intravenous contrast medium that will be used for CTA. Beta-blockers will be given if the resting heart rate is 70 beats/min.
