Coronary computed tomography angiography: principles of contrast material administration.
A conceptual framework to approach the application of contrast media in computed tomography angiography (CTA) is discussed. With an adequate conceptual framework, the physician or technologist should be able to modify or create CTA protocols to address specific clinical and patient circumstances. The focus of this review is coronary CTA, but the basic principles are applicable to CTA in any arterial system.
