Background: Coronary Computed Tomography Angiography (CTA) has become one of
the most important diagnostic imaging modalities for the evaluation of coronary artery diseases.
During coronary computed CTA, sufficient vascular enhancement is essential for the accurate detection
and evaluation of lesions in the coronary arteries. To obtain optimal contrast enhancement
and perform appropriate clinical coronary CTA, physicians, radiologists, and radiology technologists
should acquire a basic knowledge of contrast injection protocols.
Conclusion: This review article summarizes the basic concepts of contrast injection protocols for
Keywords: CT angiography, computed tomography, ECG, physicians, radiologists, radiology technologists.
